Porsche Cayenne 958.1 GTS Handbook

Buying, servicing and modifying a 2013–14 Cayenne GTS · 4.8 V8

I'm hunting for a 2013-14 958.1 Cayenne GTS - the last of the naturally aspirated V8s - and I'd like to do most of the servicing myself. So I built an agent stack to do the homework: five research streams across forums, owner reports and Australian specialists, plus 40-odd YouTube videos read through their transcripts so I didn't have to sit through them all. Everything here links back to where it came from.

It was researched in September 2026, so it will date. It isn't advice - check part numbers against the car's VIN, and get any car you're serious about inspected.

Which 958 Cayenne to buy: the verdict#

What five research streams and 40-odd videos agreed on

The 2013–14 958.1 GTS is the sweet spot: the last naturally aspirated V8, past the early-958 faults, and workable from the top.

Why#

4.8 V8 without turbos. Plugs, coils, filters and fluids are driveway jobs; the 958.2's twin-turbo V6 is “buried”.
Clear of the early faults. The cam-bolt failures stop at builds before 13/09/2011; bore scoring is rare on the 958 4.8.
Nothing GTS-specific fails. Its weak points are shared with the S, so parts and know-how are everywhere.

Alternatives#

2013–14 958.1 S (same V8) at around $37k is the value pick, and the difference buys a healthy repair fund. The GTS premium is desirability, not reliability.
MY16 958.2 GTS ($48–55k) if the V8 isn't the point: faster and newer, but harder to service at home.

Avoid#

Hybrids - a high-voltage battery runs A$20–26k.
Diesel for a home mechanic - its big failures are engine-out jobs.
957s unless MY09–10 with a clean borescope; 9Y0s start well above 958 money.

The one big risk

The transfer case. Twelve YouTube channels and every forum stream name it the 958's weak point. Change its fluid every 30,000–60,000 km, as owners and specialists do (Porsche's schedule says 240,000 km). It's a driveway job - torque the plugs carefully, the case is aluminium. Ask every seller when it was last done, and keep A$6–8k in reserve until the history is clear. And assume air suspension: Australian S and GTS cars came with it as standard.

Before you buy a 958 Cayenne GTS#

What to look and feel for, what to ask the seller, and who can inspect it

paperwork#

Oil services every 12 months or 15,000 km, with no stretched intervals.Service history matters more than mileage; stretched oil intervals are a red flag.
Spark plugs done every 45,000 km or 4 years.Worn plugs and coils cause misfires around 100-130k km; plugs never done by 90k km is a red flag.
Evidence of transfer case, diff and ATF fluid changes.Fluid changes prevent and often fix transfer case slipping; the factory 'lifetime' 240,000 km interval is too long.
Invoice for the revised thermostat housing (94810608002), water pump and aluminium pulley.The glued pipe at the thermostat housing is the top coolant risk; the revised housing uses threaded pipes.
Any transfer case replacement, with invoice and part number.A recent replacement with no invoice is a red flag; a documented replacement adds value.
Get the build option list by VIN from a Porsche Centre: air suspension, PDCC, PTV Plus, PCCB.Each option changes running costs; PTV Plus cars see more rear diff noise, PDCC adds a hydraulic system.
Ask a Porsche Centre to run the VIN for open campaigns.AU recall history includes a 2015 under-bonnet fuel leak recall on petrol models.
Confirm the engine is the 4.8 V8, especially on any MY15-plated car.The July 2014 facelift (958.2) moved the S and GTS to a 3.6 twin-turbo V6.
On any 2011 S or Turbo, check the build date against 28/04/2010-13/09/2011 and whether the cam bolts were replaced.Shearing VarioCam bolts can stall the engine and, in the worst case, need a new engine.

scan#

Read stored and pending codes: misfires, P0016-P0019 cam/crank correlation, P0171/P0174 lean, air suspension and transfer case faults.Surfaces coil, PCV, timing and driveline faults the seller may not mention.
Watch ATF temperature behaviour with the scan tool.The Aisin 8-speed needs correct fluid level and condition; temperature is read by scan tool.

test drive#

Engine starts easily and settles to a steady idle almost immediately.CarsGuide's basic health check; rough idle can point to coils, plugs, PCV or carbon.
At full steering lock, accelerate hard and feel for hop or slip.The standard test for a failing transfer case.
Feel for shudder at low speed and in turns, and RPM flare followed by a lurch between shifts.Binding or slipping transfer case clutch pack.
Listen for harsh 2-3 upshifts and a clunky 5-4 downshift, and slurred shifts when warm.Valve body issues, or the transfer case slipping.
Feel for thumping or vibration under the centre console on acceleration, or a whine that fades as it warms.Failed driveshaft centre support bearing.

under the car#

If possible, see the car after it has been parked overnight and check for a sagging corner.A corner dropping overnight is the typical air strut leak.
Look for coolant crust under the engine and at the rear crossover near the firewall.Rear coolant fittings are a secondary leak point on the 958 V8.
Check the timing chain cover area and rear main seal for oil.A timing cover leak is an engine-out reseal per Porsche's bulletin - walk away or price it in.
Inspect the driveshaft centre bearing rubber for cracks.The rubber dry-rots at 10-15 years; the OEM part is a whole driveshaft.
Check disc lips and pad life; GTS front discs should be 360 mm; confirm any yellow (PCCB) calipers are genuine.Brakes are a major running cost; painted calipers can pass off steel brakes as ceramic.
Look for off-road scars underneath and trolley or parking dents.CarsGuide advises passing on cars that look off-roaded unless the price reflects it.

engine bay#

Sweet coolant smell when hot, crust at the front thermostat housing and under the intake, low reservoir level.The glued thermostat housing pipe and plastic vent pipes are the top coolant failures.
Check the valve covers for oil and listen for a whistle at idle.A whistle usually means the integrated PCV diaphragm has failed and the cover needs replacing.
Borescope a few cylinders.Bore scoring is rare on the 4.8 but not zero; cheap insurance.

cabin#

Test every button and switch, and the PCM.958 electrics are sensitive to weak batteries; trim buttons crack.
Open every door from the outside handle, especially the rear passenger door.Door lock actuators fail, rear passenger first.
Run the Bose audio and listen for dropouts or a pop at start-up.The Bose amplifier in the boot is a common failure (~£900 UK).
Check the front footwells and carpets for damp or a musty smell.Blocked sunroof drains flood the footwells, where control modules sit.
Cycle every ride height level, time the compressor and watch for chassis warnings.Slow raising or warnings point to leaking struts or a tired compressor.
Check the rear seats for kick damage and the trim for cracks and rattles.Signs of rough family use; trim is fragile.

Ask the seller#

Can I see the full service history - who did each service, and at what intervals? Service history matters more than mileage; dealer-to-independent jumps with gaps are a red flag.
Has the thermostat housing been replaced with the revised threaded version, and when were the water pump and pulley done? The glued coolant pipe is the top engine-bay risk; a documented fix is worth money.
Has the transfer case ever been replaced, or its fluid changed? Do you have the invoice and part number? The transfer case is the biggest driveline risk; fluid changes are the main prevention.
When were the spark plugs and coils last done? Plugs are due every 45,000 km; plugs and coils are a likely 100-130k km job.
Have the ATF and diff fluids ever been changed? The factory says 240,000 km; owners change them much earlier.
Does it ever need coolant or oil topped up between services? Coolant top-ups without a documented repair point to a slow leak.
Has any air suspension work been done - struts, compressor or 'no fault found' visits? Air suspension is standard on AU V8s and a major cost at this mileage.
Has any oil leak been noted at a service, especially at the timing chain cover? A timing cover leak is an engine-out reseal.
How old is the battery? Weak batteries cause electrical faults on the 958.
Which options does it have - air suspension, PTV Plus, PDCC, ceramic brakes? Each changes running costs and what can fail.
Has there ever been water in the footwells, or have the sunroof drains been cleared? Flooded footwells can kill control modules.
Has recall work been done? Confirms open campaigns such as the petrol fuel-leak recall have been closed.
Has the car been used off-road? CarsGuide advises passing on off-roaded cars unless priced accordingly.
Is there a known fault or reason behind the asking price? A car priced well below similar ones (e.g. the $44,500 WA GTS) needs an explanation before it's a bargain.

How to find a car's options#

The option sticker. On earlier Cayennes the list of three-character option codes is printed on a sticker in the service book and on another under the boot floor near the spare wheel. On 958s it's hit and miss - some owners report the service book only carries a black label with the VIN and engine code - so lift the boot floor and look. 6speedonline.com · 6speedonline.com · pelicanparts.com
A Porsche Centre printout. Give any Porsche Centre or independent specialist with PIWIS the VIN and ask for the factory equipment list. It's the most reliable source outside the US. rennlist.com · pistonheads.com
Porsche Production Specification. Porsche's online vehicle documentation service sells a Production Specification with the original options, colours and build date for US$150. Porsche says it covers all VINs, but it's run by Porsche Cars North America, so check it will issue one for a non-US car before paying. The Classic Technical Certificate doesn't cover the 958 - only the first-generation Cayenne. newsroom.porsche.com
VIN build-sheet sites. vinanalytics.com returns a full option list for many Cayennes with a free account. Packages hide their contents - a Turbo S includes PDCC and PTV Plus without listing them - so read the list against the sales brochure for that model year. rennlist.com
Physical tells. Sport Chrono has a stopwatch on top of the dash. PCCB has yellow calipers - check they're genuine, not painted. stuttcars.com · pistonheads.com

Known faults on the 958 Cayenne GTS#

958.1 GTS and S, 4.8 V8 - what fails, what it costs, and who fixes it

24 faults, most likely first

LikelyDIY with carecooling

Glued aluminium coolant pipe lets go at the thermostat housing#

Coolant smell when hot, puddles under the engine, sudden coolant loss (one owner heard a 'pop'), rising engine temperature.

When Any mileage - reports from under 10k to over 200k miles; several around 80-83k miles (~130k km); one 2013 GTS at 38k milesCost Dealer fix US$1,800-2,800. Parts ~US$310 (revised housing) + ~US$200 (thermostat); ~6 h book labour, intake manifold and injection rail off.

Prevent it: Fit the revised threaded housing (94810608000 superseded by 94810608002) before it fails; ask whether it has been done.

Transfer case clutch pack binds or slips#

Jerky shifts in low gears under power (binding); brief RPM flare then a lurch on shifts (slipping); shudder at low speed and in turns; hop or slip when accelerating hard at full steering lock.

When Binding failures under ~30k miles; slipping failures over ~50k miles (~80k km). One 2011 S had cases at 14.9k, 71k, 83k and 107k miles.Cost Reman ~US$2,400 incl. US$900 refundable core; ~US$6k dealer (one owner); UK specialist 'approach £3,000 including labour'. The US 10-year extended warranty has expired on every 2011-2014 car.

Prevent it: Change the transfer case fluid every 25-30k km (owners do 15-20k miles) despite the factory 240,000 km interval; fluid changes 'have fixed a LOT of them'.

LikelyDIY with caresuspension

Air strut leaks and compressor burn-out (air is standard on Australian S and GTS)#

A corner sags overnight (usually the O-ring at the top of the air spring); compressor runs long; 'Chassis System Failure' or 'Regulation not permissible' warnings.

When One aggregator: 80-120k km, spreading corner to corner. One high-mileage GTS had all struts done at 150k miles.Cost US: front strut ~US$1,320, rear ~US$1,257 (eEuroparts); Arnott new ~US$800, rebuilt OEM ~US$1,000 each; compressor part US$459; valve block ~US$367.

Prevent it: Fix a leaking strut early so the compressor isn't over-worked. One experienced owner now prefers genuine Porsche struts over Arnott.

Worn spark plugs and failing ignition coils#

Misfires under acceleration, rough idle.

When 60,000-80,000 miles (~100-130k km)Cost AU dealer plugs $760 (every 45,000 km / 4 years); plugs + coils US$600-1,200 at a shop.

Prevent it: Plugs every 45,000 km or 4 years. Coil connectors go brittle and the aluminium coil bolts are one-use - finger tight only.

Heavy brake wear, and ABS/pad-wear sensor loom faults#

Lipped discs, short pad life; brake/ABS warnings from damaged sensor looms that get misdiagnosed as worn pads. 958.1 GTS front discs are 360 mm (390 mm is the Turbo, and the GTS from 2016).

Cost UK specialist: '£500+ per axle; £1,000+ for a full set'. Brakes and tyres are the biggest running costs.

Prevent it: Rear pads normally need no scan tool; rear rotors may need the scan tool's EPB service mode if the parking-brake drum has a lip.

Oil consumption#

Needing top-ups between services.

Cost Porsche allows up to ~0.8 L/1,000 km. Owners report from half a quart per 5-6k miles (2014 S) to 1 L per ~1,800-3,000 km (GTS). Claims of 'abnormally high' consumption are weak.

958 Cayenne service schedule, fluids and torques#

Schedule, fluids and capacities, torques and tyres - check a VIN parts lookup before ordering

Before you start

Jack mode. Set Normal level with the ride-height rocker. With the ignition on, hold the rocker switch FORWARD for 10-15 seconds. Release it: a message appears on the instrument display and the car can now be raised. To switch levelling back on, hold the rocker forward for 10-15 seconds again, or just drive off. manualslib.com · manualslib.com · ecarguides.com
Jacking points. Lift only at the four sill jacking points (the jack head must seat in the cut-out) or at the jacking points for a trolley jack or lifting platform. Never jack under the engine, transmission or axles. For jack stands, eCarGuides jacks at the front centre crossmember and at the rear crossmember just ahead of the rear diff, between the exhaust pipes, then puts the stands under the jacking points. The car must be level for the transfer case, diff and ATF levels. Never work under a car supported only by a jack. manualslib.com · manualslib.com · ecarguides.com · ecarguides.com
Brake size. The brief assumed 390 mm front brakes. Porsche's MY14 brochure says the GTS has 360x36 mm front discs (390 mm is the Turbo). eCarGuides, Stuttcars and two Rennlist threads ('390 added to GTS for 2016 and up'; 'Red calipers on a GTS - 360mm') agree; eEuroparts disagrees. Measure the disc or check the VIN option list. manua.ls · ecarguides.com · stuttcars.com · rennlist.com · rennlist.com · eeuroparts.com
Stands, always. Jack mode stops the car levelling but doesn't lock it - one owner had an air spring deflate in jack mode.

Item	Every	Months	What owners do	Source
Engine oil and filter (Annual Maintenance)verified	15,000 km	12	Many owners change at 7,500-10,000 km or yearly, whichever comes first (eCarGuides recommends about 7,500 km). Reset the counter with the scan tool.	dealer.porsche.com · dealer.porsche.com · ecarguides.com · pcarwise.com

Fluids and capacities#

System	Spec	Part	Capacity	Notes
Engine oil (4.8 NA V8)verified	Porsche A40 approval. SAE 0W-40 for all temperatures; 5W-40 or 5W-50 above -25 °C. AU examples: Mobil 1 Triple Action 0W-40; Castrol EDGE 0W-40 A3/B4 (its product page lists Porsche A40).	–	9.0 L	9.0 L with a filter change (8.5 L without) per the owner's manual; a 2013 GTS owner confirms '9.5 qts' (about 9.0 L). eCarGuides says 10 US qt (9.46 L). There is no dipstick: read the level in the cluster (Vehicle > Oil level). Fill about 8.5 L, run it warm, then top up in 0.25 L steps; one display segment is about 0.25 L. The min-max span is about 1.0 L per the manual, or about 1.4 L per eCarGuides. Buy 10 L. manualslib.com · manualslib.com · rennlist.com · ecarguides.com · supercheapauto.com.au
Automatic transmission (Aisin 8-speed Tiptronic S)conflicting	Porsche ATF 958 300 540 00, the same fluid as VW G 055 540 A2 (the dealer confirmed the bottle is labelled G055 540 A2). FCP now lists Genuine Porsche 000 043 306 24 against that number, which is probably a supersession. Owners also use Febi 29934, Ravenol J1D2122 and Fuchs Titan 4400 as equivalents; these are owner-reported, not Porsche-approved.	958 300 540 00 (G 055 540 A2)	13.45 L	13.45 L is the total factory fill (owner's manual, Cayenne S). A service changes far less: about 6 L from the drain plug and pan without opening the cooler lines (Rennlist); 7.4-9.0 L for a drain and filter change (eEuroparts); eCarGuides buys 10 L. Fill through the drain plug with adapter VAS 6262/2 (M10x1). Porsche procedure WM 370235: if the cooler lines were opened, warm the ATF to 100 °C to open the thermostat, then let it cool to about 35 °C. Engine at idle, A/C off, shift slowly P-R-N-D three times. The level is correct when ATF drips continuously from the overflow tube. eEuroparts gives a 35-45 °C window and eCarGuides 35-40 °C. Read ATF temperature with the scan tool; an IR gun reads about 6 °C off (Rennlist). manualslib.com · rennlist.com · rennlist.com · rennlist.com · eeuroparts.com · ecarguides.com
Transfer case (PTM multi-plate)verified	Porsche transfer case fluid 000 043 305 63, sold as an 850 ml bottle. eCarGuides uses Motul ATF VI and some owners use Ravenol; those are substitutes, not the Porsche specification.	000 043 305 63	0.875 L	0.875 L per the owner's manual; eCarGuides and Rennlist say about 0.78 L. The car must be level. Remove the FILL plug first, drain, then fill until it overflows. Two new plugs 955 301 115 01, which come with thread sealant. Buy 2 bottles: one 850 ml bottle is marginal for 0.875 L. The Diesel/Hybrid Torsen case uses a different fluid. manualslib.com · fcpeuro.com · ecarguides.com · rennlist.com
Front differentialverified	75W-90 gear oil. Owners say non-locking diffs take any synthetic 75W-90; eCarGuides uses Motul Gear 300 75W-90. Porsche's own front-diff part number was not confirmed.	–	0.5 L	0.5 L (owner's manual and eCarGuides). The level should sit 7 mm (±2) below the lower edge of the fill hole. The fill plug is hard to reach: use a stubby 8 mm hex and a low-profile ratchet. Two new plugs 955 332 057 00. manualslib.com · ecarguides.com · rennlist.com · rennlist.com · rennlist.com
Rear differential (open / standard)verified	75W-90 gear oil (Motul Gear 300 75W-90 per eCarGuides).	–	1.0 L	1.0 L (owner's manual and eCarGuides). The level should sit 6 mm (±2) below the fill hole. Two new plugs 955 332 057 00. manualslib.com · ecarguides.com · rennlist.com
Rear differential (locking / PTV Plus, if fitted)conflicting	Porsche limited-slip 75W-90 with friction modifier. Part number conflict: Rennlist gives the latest number as 000 043 300 37, while FCP lists Genuine Porsche 000 043 305 03 '75W90 ... With Limited Slip Differential' for the same search. eCarGuides uses Motul Gear 300 LS 75W-90.	000 043 300 37 or 000 043 305 03 (conflicting)	1.3 L	1.3 L (owner's manual and eCarGuides). If you just fill to overflow it takes only about 0.5 L. With the wheels off the ground, alternately spin them and add oil. One owner got 1.4 L in this way. Check the option list for PTV Plus (I1Y1 per Rennlist). manualslib.com · ecarguides.com · rennlist.com · rennlist.com · fcpeuro.com
Engine coolantsingle source	Porsche antifreeze only (owner's manual). eEuroparts identifies it as the pink Si-OAT type (G12++, VW TL 774-G) for 2010+ Porsches; owners cite Zerex G40 as equivalent. Owners link to 000 043 301 05 and 000 043 305 75 (1 US gal).	000 043 301 05 or 000 043 305 75 (owner-cited, unverified)	19.5 L	18.0-21.0 L depending on equipment (owner's manual, Cayenne S/Turbo); 19.5 is the midpoint. Mix 50/50 with distilled water for protection to -35 °C. Porsche: 'Cooling systems with thermal management ... must be vacuum-filled'. Use an Airlift/Schwaben-type vacuum filler; if bleeding manually, run the heater/defroster. An owner drain-and-refill used about 2 US gal of concentrate (about 7.6 L) plus water, because the block doesn't drain fully. manualslib.com · manualslib.com · eeuroparts.com · rennlist.com · rennlist.com · rennlist.com
Brake fluidverified	Original Porsche brake fluid (owner's manual), a DOT 4 type. eCarGuides uses ATE Typ 200 DOT 4. FCP maps 000 043 203 66 to Pentosin Super DOT 4 (single source).	–	1.02 L	1.02 L per the owner's manual; eCarGuides says 0.95 L. For a flush, buy 2 L (eCarGuides bleeds about 1.6 L). Order: rear passenger-side, rear driver-side, front passenger-side, front driver-side. Each calliper has inner and outer bleeders (11 mm). manualslib.com · ecarguides.com · fcpeuro.com
Power steering (hydraulic)verified	Pentosin CHF 202 (green). The steering is hydraulic, driven by a tandem pump shared with PDCC.	–	1.85 L	1.85 L per the 2011 958 owner's manual. The reservoir (955 314 015 30) has a built-in filter; check the level with the dipstick in the cap. manualslib.com · ecarguides.com · rennlist.com · rennlist.com

All	N-rated (Porsche-approved) tyres	–	The manual says pressures apply only to Porsche-approved tyre makes and types, and that the load index and speed rating are minimums. N-spec (N0, N1, ...) is a Porsche-tuned construction and compound, not a higher load or speed rating (Rennlist). Owners report N-spec Michelin Latitude and Pirelli P Zero on Cayennes. AU prices for 275/45 R20 on 20/09/2026 (Tyroola, N-rating not stated): Michelin Pilot Sport 5 XL AU$500 each, Pirelli Scorpion Zero Asimmetrico AU$495 each. A later 958.2 manual gives lower part-load pressures (34/42 psi), so the car's own placard is authoritative.

Jobs you can do at home#

Job	Rating	Time	Needs	Notes
Oil and filter	Easy	–	About 9.5 L Porsche A40 oil (e.g. Mobil 1 0W-40); filter 948 107 222 00 / Mahle OX254D4; filter-cap socket; belly pans off	NA V8 filter housing is under the engine, in front of and above the drain plug (on the Turbo it is on top). 958-107-222-10 is the V6 filter, not the V8. No dipstick - level is read in the instrument cluster. FCP Euro OX254D4 fitment
Spark plugs (8)	Easy	1.5-2.5 h	Bosch FGR5NQE04 x8; 5/8 in magnetic plug socket; torque wrench (22 ft-lb); triple-square and Torx sets	Remove side engine panels, passenger-side engine torque strut, coil covers and driver-side intake cover. Coil bolts are aluminium (one-time use, owners often reuse). eCarGuides 958.1 S/GTS spark plugs
Ignition coils	Easy	–	Coils 948 602 104 13	Same access as the spark plugs. Rennlist V8 plug/coil DIY
Air filters	Easy	–		Rating is a judgement: the airbox lids come off during the plug job. Dealer price AU$212-327 for comparison. Porsche Centre Gold Coast Cayenne pricing
Coolant change and bleed	With care	–	Vacuum coolant refill tool makes it far easier	No easy radiator drain on the 958. Owners either vacuum-fill ('no bleeding necessary') or open the vent-line ring, squeeze hoses and drive with the vent open. Replacing the Y-shaped vent line under the intake manifold is a much bigger job ('What a job!'). Rennlist 958 coolant bleed
8-speed Tiptronic fluid (ATF) and filter	Special tool	3 h	Scan tool to read ATF temperature (or IR thermometer workaround); fill adapter VAS 6262/2; fluid pump; car level on stands; about 10 L ATF	Level is set at 35-45 C fluid temperature. Drain and filter change uses 7.4-9.0 L. eCarGuides suggests every 8 years / 80,000 miles. eCarGuides 958 ATF change
Transfer case fluid	Easy	–	About 0.78 L (PTM multi-plate) - fluid 000 043 305 63 for petrol S/GTS; Diesel/Hybrid Torsen case takes 958 341 536 00 (0.50 L)	Easy access but torque-critical: one owner cracked the housing mixing up 15 ft-lb and 20 Nm. Transfer case trouble is a known 958 issue on all but the diesels; fresh fluid often cures early symptoms. Rennlist 958 transfer case fluid
Front and rear differential fluid	With care	–	8 mm stubby hex, low-profile ratchet, fluid pump, torque wrench (35 Nm plugs)	Front fill plug is tight to reach. With PTV Plus (locking rear diff) the car must be off the ground so the wheels can be spun while filling in stages (about 1.3-1.4 L). No scan tool needed. Rennlist diff fluid DIY
Front brakes (958.1 GTS 360 mm)	With care	–	Torque wrench to 104 ft-lb; new caliper bolts (one-time use)	The 958.1 GTS runs 360 mm front discs with red calipers (390 mm is the Turbo and the 2016-on GTS) - measure the disc or check the VIN before ordering. Rotors are heavy. eEuroparts 958 brake service
Rear brakes and parking brake	With care	–	Scan tool only for EPB service mode / calibration when rotors or shoes are changed	The 958 parking brake is a drum-in-hat shoe inside the rear rotor. Owners change rear pads without a scanner. Rotor or shoe jobs sometimes need service mode and calibration; shoes can also be adjusted through the rotor hole. Rear caliper bolts 63 ft-lb. Rennlist rear brakes without a scanner
Air suspension struts (if fitted)	With care	–	Ball-joint puller; scan tool for ride-height calibration afterwards	Front: stabiliser link, air line, upper control arm ball joint, three top nuts, lower bolt. Rear: access from the cargo floor. Owners warn against aftermarket-tool ride-height calibrations - consider leaving calibration to a specialist. Check whether the car has air suspension at all. eEuroparts 958 air suspension guide

Diagnostic and coding tools#

Launch X431 (V+, PROS Mini, Diagun IV, CRP919X BT / Pros Elite)Buy this

The recommended owner-level coding tool for the 958. Rules: charger on (above 12.4V), never 'Online Coding' or 'Restore Default Setting', screenshot values before changing. Treat air-suspension functions as expert-only.

Does: Offline coding of all the owner-level changes above (confirmed on 958s in the Rennlist coding thread); Battery coding (Gateway); Service resets, fault reading and clearing, bi-directional tests; Custom TPMS preset in the instrument cluster; Works on other car makes too

Can't: Key and fob programming (online coding needs a Porsche dealer account); Factory tow-module retrofit on a 2013 GTS (needed PIWIS or the dealer); Some modules (one owner needed PIWIS for a BCM function)

Price: Australian price not verified. A Rennlist owner put coding-capable tools at USD 900-1,100.

Rennlist coding guide · Rennlist: PIWIS or Launch X431? · Spanner Rash: Launch X431 Pros Elite on a Cayenne

Foxwell NT530 (Porsche)

Fine for servicing, but it can't do any of the coding changes. Its ride-height calibration is risky: a 2016 GTS owner had the front about 50 mm higher than the rear before sorting it out (needs battery above 12.1V, ignition on, engine off). Software updates need a Windows PC.

Does: Service interval resets; Reading and clearing fault codes; Height sensor calibration (Level control/PASM > Special functions)

Can't: Control module coding or programming. Per Foxwell's own product page, as quoted by an owner: 'doesn't support control module coding and programming'; Key programming

Rennlist: Foxwell NT530 doesn't have a programming function · Rennlist: Foxwell NT530 ride height calibration

iCarsoft POR V2 / V3

A diagnostic and reset tool only. Warning: an iCarSoft 3.0 user poking at air-suspension diagnostics was left with a permanent 'Chassis System Failure' and dead ride-height/PASM buttons. The likely cause was the level-control module being left in diagnostic mode. Keep it away from air-suspension functions on the GTS.

Does: Service resets; Battery registration; Code reading and diagnostics

Can't: Coding (confirmed for POR V2.0 in the Rennlist coding thread)

Rennlist: Chassis System Failure after using iCarSoft 3.0 · Rennlist coding guide

PIWIS II/III clone

Not recommended as a first tool. Buggy, often in German, and risky. Leave dealer-level jobs to a dealer or a specialist with a genuine PIWIS.

Does: Dealer-level functions, including key programming if you have the codes; Consistency-checked multi-ECU coding

Can't: Guarantee: it's counterfeit software, and stories exist of misconfigured clones bricking engine and transmission control units; Some hidden items the Launch reaches weren't visible on one PIWIS2 v14

Price: About USD 450 for PIWIS II clones (May 2020); decent clones with an interface 'USD 1000 or more'. The real PIWIS is leased to dealers for about USD 20k a year.

Rennlist: PIWIS or Launch X431? · Rennlist coding guide

Autel MaxiSys

Capable but pricier. The Launch has far more 958-specific coding reports.

Does: Coded mirror auto-fold on a 2011 Cayenne Turbo; Coded comfort windows on a 2019 911 (MS908)

Can't: Broad 958 coding not confirmed in the sources

Hidden features (no tool needed)#

Built-in tricks most owners never find: a hidden cluster menu, key-fob window and mirror controls, memory buttons that store climate and start-up volume, and a programmable tailgate height. Free and good for a first session together.

$0Time 30 minReversible

Free.

Gotchas

Hidden cluster menu: scroll to the vehicle title in the right-hand display and press the stalk button.
Hold the fob unlock or lock button to move all the windows (seen on a UK car; may vary by market).
Press lock twice and hold, on the fob or door handle, to fold the mirrors.
Memory buttons also save the start-up volume. Set it low before saving.
Tailgate height: stop it where you want, then hold the tailgate button to program it.
B-pillar button disables the interior motion sensor (useful for a dog in a locked car).
The rear wiper wipes automatically when you select reverse after using the front wipers.

Sport exhaust valves always open#

Pull the vacuum hoses off the two factory sport exhaust flaps at the tailpipes so the valves stay open. It's the best-value sound upgrade: free, fully reversible and using factory hardware.

$0Time MinutesReversible

Free.

The exhaust stays factory, but the stationary noise limit (certified level + 5 dB(A)) still applies. The GTS's certified figure wasn't found, so a stationary test at an inspection station would settle it.

Gotchas

On MY13 the valves open only with the Sport button; MY14 has a separate exhaust button.
Tie up the hose and tape the actuator port so nothing gets in.
A 2013 GTS owner reports no warning lights.
The cabin sound barely changes; most of the difference is outside the car.
A dedicated exhaust button can't be added to a MY13: the switch panel is one coded unit.

Leather clean and bolster dye repair#

Driver's outer bolster and steering wheel lose their colour coat and go shiny with age. Cleaning and a colour-matched dye kit fix most of it; badly torn seats need a new cover.

$30–$125

Gyeon leather cleaner $26.99-28.99; Leatherique system $74.99 (250 mL) or $124.99 (500 mL). New OEM 18-way seat cover was about US$930 in 2022.

Gotchas

On ventilated or perforated seats, mist cleaner onto the cloth, never the seat - liquid in the holes swells the leather.
One owner's Chemical Guys leather wipes marked Bordeaux red leather.
Clean leather looks matte, not shiny.

Alcantara clean and protect#

The GTS has Alcantara seat centres, armrest, door inserts, headliner and pillars (and the wheel rim if optioned); it goes flat and matted with use. Clean it properly before paying for a retrim - owners find it is often matted, not worn through.

$70–$125Time Protectant needs 24-48 hours to cure before it gets wet

Product cost. Bowden's Own Fabra Cadabra $22.99, Plush Brush $32.99, Fabratection $46.99; Sonax Alcantara cleaner $29.99; Mint rubber brush $8.99.

Gotchas

Never spray cleaner straight onto the fabric - spray the pad or brush.

Wireless CarPlay / Android Auto (keep the PCM)#

Adds wireless CarPlay and Android Auto to the factory PCM 3.1 screen. Best buy is a fibre-optic (MOST) interface such as the Mr12Volt P3000: it keeps digital Bose/Burmester sound, the factory mic, steering-wheel controls and the reversing camera. Avoid full screen replacements.

$800–$1,500Time 1.5-3 h (experienced) to 5 h; one owner took 10 h fixing ribbon seatingReversible

Mr12Volt P3000-PM31 is USD 549 (about AUD 800-850 at an assumed 1.5 rate, plus shipping and GST). Euro Car Upgrades (Buderim QLD) kit AUD 990. Installed: AUD 1,430 (Autofidelity VIC), AUD 1,249.95-1,499.95 (Car Stereo Shop WA). Cheaper ISUDAR board ~USD 300; AliExpress boards ~USD 100-160.

Gotchas

Check the centre armrest for AUX/USB first. Some 958s (including one owner's MY14 GTS) have none. AUX-based kits then have no audio path; the MOST-type Mr12Volt still works.
Buy a current Mr12Volt P3000. The old blue P1000 box doesn't support the factory mic (grey P2000 does and can be upgraded).
Ribbon-cable clamps are fragile on 10-year-old PCMs and must be fully seated. Test in the car before reassembling.
An ISUDAR board burnt a chip on one 2014 958's PCM main board (single report).
If a factory TV tuner is fitted, Mr12Volt needs it bypassed with an optical loop.
Unresolved: whether FM radio can play while CarPlay navigation is on screen (Mr12Volt uses the TV source). Ask the seller.

Cooling system teardown#

Check whether the thermostat housing pipes are glued or threaded. If they're glued, fit the threaded housing and do the vent Y-pipe, water pump, thermostat and rear crossover fitting in one teardown. MY13-14 cars may already have the threaded pipes, so inspect before buying parts.

$1,000–$1,500Time About 6 hours for the housing alone (AllData labour time)

Parts about A$1,000-1,500. A dealer charged US$1,800 (≈A$2,500) for the housing fix alone in 2018. Engine-out quotes for the rear crossover reached US$8-10k.

Gotchas and part numbers

Wiggle the pipes where they enter the thermostat housing. Any movement means plan the replacement.
The intake manifold and fuel rail must come off. Replace the single-use aluminium bolts and the intake manifold gaskets.
The plastic cylinder-head vent Y-pipe cracks with age and leaks into the engine V. Replace it while you're in there.
The glued rear crossover fitting can be pinned in place (drill, tap, Loctite 271, stainless cap screw) with the engine in, if you remove the high-pressure fuel pump.
Removing the three-piece false firewall gives about 8 inches more room.
Replace the O-ring on the expansion tank's bottom hose while the system is drained.
Owners recommend a vacuum fill tool to avoid airlocks.

Replace TPMS sensors#

Original tyre-pressure sensors last about 11-12 years, so a MY13-14 car is likely due. Owners recommend Huf sensors, and the car relearns them through the instrument cluster menu with no tool.

Time Tyre-shop fit, then a short relearn drive

Not priced. Easiest to have fitted at the next tyre change.

Gotchas

Porsche changed TPMS systems partway through MY2014. Have a dealer confirm the right sensor from the VIN.
Avoid cheap knock-off sensors.
Don't carry the old wheels in the car during the relearn; the car sees 8 sensors and won't learn.
Don't confirm 'tyre change' settings until the system reads the new sensors.

Coding: convenience features#

Scan-tool coding changes: one-touch indicator 3 to 5 flashes, windows up/down from the key fob, mirrors auto-fold on lock, auto-lock speed, teardrop wipe, and tailgate beep off. Each is a single value change and can be changed back.

Time 30-60 minReversible

Needs a coding-capable scan tool such as a Launch X431 (see tools).

Gotchas

Put a battery charger on first; keep above 12.4V while writing to modules.
Never use 'Online Coding' or 'Restore Default Setting'. One owner zeroed his parking-brake module that way.
Screenshot every original value first; 'Back Up All Coding' doesn't work on the Launch.
Many changes only show after you switch off, lock the car and wait 30 seconds.
Mirror auto-fold needs power-folding mirrors already fitted. Once coded, 'Mirror retract' appears in the PCM car options.
Indicator flashes may already be adjustable in the cluster settings menu. Check first.

Transfer case fluid change#

Drain and refill the PL72 transfer case with the correct fluid and keep doing it. It's the cheapest protection against the 958's most common expensive failure, and owners often report symptoms clearing after one to three changes.

$150

Under about A$150 for fluid and new plugs. If it fails: dealer replacement US$5,000-5,500 in 2024 (≈A$7,000-7,700); AWD.tech remanufactured unit €1,650-1,890 (≈A$2,650-3,050).

Gotchas and part numbers

Torque the drain and fill plugs to 20 Nm (15 ft-lb). An owner cracked the case by using a 1/2" wrench set to 20 ft-lb, so use a 3/8" or 1/4" wrench.
Remove the fill plug first, so you're never left with an empty case you can't refill.
It's fill-to-overflow: about 0.78-0.85 L, with the car level.
Use new drain and fill plugs; they come with thread sealant.
Never use generic gear oil. One shop's Motul 75W-80 caused immediate shudder.
Diagnosis: unplug the transfer case stepper-motor connector and drive gently. If the lurch goes away, the problem is the transfer case.
Interval from owners: every 15,000-30,000 km, or every second oil change.
Keep the same tyre size and wear on all four corners; replace all four together.
Turn on air-suspension jack mode before lifting: hold the level switch forward for about 10 seconds until the lights blink.

Leather dash lifting re-glue (if fitted)#

The leather dash is optional on the GTS; where fitted it commonly shrinks and lifts behind the instruments and near the passenger A-pillar, worse in sun. Hydrate it, inject leather glue and weight it down early - once it has shrunk back it cannot be stretched.

Time About a week of daily conditioning, then 12-24 hours weighted after gluing

Not priced in AUD: leather glue, syringes and conditioner. Full re-cover quoted around US$3,000 by one owner.

Gotchas

Check first whether this car has the optional leather dash.
Act at the bubble stage; shrinkage is permanent.
Needle holes need massaging closed afterwards.

Brake pads and rotors (360 mm GTS set)#

The MY13-14 GTS has 360 mm front and 330 mm rear discs, not 390 mm. Fresh rotors and a low-dust ceramic pad are the sensible upgrade.

$60–$1,800Reversible

Aftermarket pads from about US$40-45 per axle (≈A$60). A full front and rear job in parts was US$800-1,300 (≈A$1,100-1,800).

Like-for-like or manufacturer-optional brakes are fine. A Turbo 390 mm conversion wasn't a GTS option, so it needs an Approved Person. Don't machine rotors below their limit.

Gotchas and part numbers

Measure the disc or do a VIN parts lookup before ordering; some sellers list 390 mm for the GTS.
Caliper bolts are torque-to-yield, so replace them. One owner quotes 140 Nm; verify in the manual.
No grease on the pad backs or shims (Porsche rule); do grease the clips and pins.

Oil separator (AOS / PCV)#

The V8's air-oil separator membrane tears with age, causing warning lights and oil use. Replace the unit or membrane on condition, or while the intake is off. A catch can is largely redundant on this engine.

$100–$430Reversible

Genuine AOS A$430 (Australian owner). An aftermarket membrane is about A$100 delivered, but one split after a year.

If a catch can is fitted, it must stay in the closed crankcase loop, never venting to atmosphere.

Gotchas

High crankcase vacuum at the oil cap is normal on these engines.
Owners report Porsche treats up to 1 L per 1,000 km of oil use as acceptable.
Membrane size is 87.5-88 mm, and there are different parts for different V8s, so order the right one.
If you fit a catch can anyway, it goes inline in the hose from the oil-mist separator to the intake plenum.

Driveshaft centre bearing#

The driveshaft carrier bearing commonly starts to whine from under the rear-seat floor. Porsche sells only the complete shaft, but a VW carrier kit or a JXB clamshell carrier fixes it far more cheaply. Most owners wait for the noise rather than replacing it early.

$420–$4,500

JXB carrier US$299.99 (≈A$420). A Timken 6007-2RS bearing is about US$15. The OEM complete shaft is over US$3,200 (≈A$4,500+).

Gotchas and part numbers

Test: push a grease needle through the bearing seal. If the noise stops, it's the bearing.
The exhaust centre section and heat shields must come off. Support the shaft with straps or a helper.

Front + rear dash cam, hardwired#

A two-channel dash cam powered from the dash-end fuse panel so the wires are hidden. Straightforward on the 958, but on this era of car the dash cam cable can knock out the PCM's GPS.

$449–$869Time 1-3 hReversible

Camera only (Dash Cams Australia: FineVu GX35 2CH AUD 449 to BlackVue Elite 10 2CH AUD 869). Add a hardwire kit; parking-mode battery packs are AUD 389-399.

Gotchas

GPS antenna sits behind the rear-view mirror. A mirror-mount dash cam's power cable dropped a 2013 GTS's nav to 0 satellites. Fix: shield the cable (foil or shielding tape) and route it away from the antenna. Check the satellite count afterwards (Map > Info > Location info).
Keep the cable behind the A-pillar airbag. On the 958 there are no screws behind the 'airbag' logo; prying it has damaged pillars.
The right-side fuse panel has empty ACC and constant-12V slots for add-a-fuse taps.
Some PCM/accessory circuits stay live 20-30 min after locking. Test which feed you're on (ACC, delayed, constant).
The rain-sensor feed at the mirror is always live, not switched.
Don't remove the vent above the fuse cover; it's bolted internally.
Rear cable: use the left tailgate conduit (the right one carries the washer hose).
Fit the supplied ferrite filter or DAB reception can suffer.

Time 30-60 minReversible

Bulbs are cheap (not priced). Needs a Launch X431-class tool (see tools).

Not researched. Exterior lights must meet Australian lighting rules, especially white LED side markers that replace amber ones. Check before fitting.

Gotchas

Number plate LEDs need built-in resistors, or you get a bulb-out warning.
Plate-light coding (rear-end electronics) sometimes fails with 'check conditions'. One owner still saw a brief startup warning and also disabled the light-out warning in the instrument cluster.
Side marker coding is in front-end electronics ('Side marker light SML in LED'). The bulb is a 194/T10.

Reversible

Not priced. Parts: harnesses 8D0973822 and 1J0973332, a 720p CVBS camera, and a Fakra-to-RCA lead.

Gotchas

The PCM only accepts CVBS. An AHD camera needs its mode wire cut to force CVBS (see the camera manual).
With a Mr12Volt, wire an extra camera's trigger to the '12v rear camera' lead, not the tail-light reverse wire. That caused a 'Left tail light defective' warning on one car.
Cars with a factory TV tuner (behind the right D-pillar) can route the camera through it. A water-damaged tuner killed one car's camera, so check the sunroof drains.

SUV prices are by quote. Brisbane sedan examples: from $375 (entry level), XPEL XR Plus ceramic $695. An Australian owner paid $490 on a small SUV.

TMR's site could not be reached (403). Limits are from We Tint Windows citing TMR's September 2017 rules; the 35% front limit includes factory glass. Confirm with TMR or an Approved Inspection Station.

Gotchas

Over-dark front windows cause night glare and poor visibility when looking left.
Check the factory privacy glass first - film stacks on it.

Air suspension lowering#

Lower the factory air suspension by coding the height sensors, by fitting lowering links or with an electronic module. It's for looks; ride reports are mixed and an alignment is needed afterwards.

$0Reversible

Coding is free if you own a capable scan tool. Links are US$55-270 (≈A$80-380). Module prices (TechArt, H&R ETS) weren't verified.

Keep at least 100 mm ground clearance and meet ADR 43. Lower by no more than one-third of the suspension travel, with front and rear lowered equally.

Gotchas

Foxwell NT530 coding fails below 12.1 V; do it with the ignition on, engine off and doors closed.
One owner briefly ended up with the front 2" higher than the rear.
Links lower every height level; some owners call the ride bouncy.

Intake valve carbon cleaning#

Walnut-blasting the direct-injected V8's intake valves. Build-up on the 958 V8 is generally mild and owners report little difference, so only do it when the intake is already off.

$700–$1,400

US$500-1,000 at shops (≈A$700-1,400) when done as a standalone job.

Gotchas

Only blast or soak cylinders whose valves are fully closed; otherwise there's a hydrolock risk.
Walnut blasting needs a good compressor with dry air and a runner adaptor.
Replace the eight intake manifold gaskets.
Owners who cleaned at 60,000-115,000 miles noticed no driving difference.

ECU tune#

An OBD-flashed remap from Softronic, Fabspeed, FVD or similar. Tuners claim about +20-30 hp on the NA V8, and owners mainly notice sharper throttle and shifts. It's reversible, but several owners say it's not worth the money for power alone.

$1,530–$2,710Reversible

Softronic US$1,095-1,395 (≈A$1,530-1,950); Fabspeed XperTune A$2,709.80. A Tunezilla gearbox (TCU) tune was about US$400.

Allowed without approval if the car still meets its ADR emissions standard. A power gain over 20% (about 62 kW on 309 kW) needs an Approved Person. Tell the insurer.

Gotchas

The Fabspeed handheld needs a Windows PC (no Mac) and pairs with one car only.
Keep a 15-25 A battery charger connected while flashing.
Softronic is tuned for US 91-93 octane (roughly 95-98 RON), so use 98 in Australia.
Expect a short relearn period with odd shifts or surging.
Cobb doesn't support the 958.
Tunes that disable rear O2 monitoring for cat deletes are emissions tampering.

Secondary cat bypass pipes#

Pipes that replace the two secondary catalytic converters for a louder V8. Not road-legal in Queensland, and owners complain about the very loud cold start and pops. Avoid.

Fabspeed A$1,598.10 (claims +11 wheel hp); Soul US$1,135 (≈A$1,590); Hanksville Hot Rods US$795 new.

They remove emission control equipment. Alternative exhausts must keep equivalent emission control, and catalytic converters may only be replaced with ADR-marked parts. Fabspeed sells them for 'closed track events and off-road use only'.

Gotchas

Very loud cold starts; several owners removed them.
Overrun pops.
No warning light reported on the 958.

Gotchas

Changing only the engine module lasts one drive cycle.
One 2011 owner did it in the air-con module ('Last Mode'). A 2018 GTS owner turned it off in all relevant modules, including 'save to last' in air-con.
With PIWIS it has to be coded in 4 ECUs together, or the change silently doesn't save.

958 Cayenne GTS questions, answered#

The short answers, drawn from the research above

Which 958 Cayenne is the best one to buy?

The 2013-14 958.1 GTS. It has the last naturally aspirated V8 (the 4.8), it's past the early-958 cam-bolt faults, and nothing GTS-specific fails - its weak points are shared with the S. A 2013-14 958.1 S has the same V8 and is the value pick. A MY16 958.2 GTS is faster and newer, but its twin-turbo V6 is harder to service at home.

What is the most common problem with the 958 Cayenne?

The transfer case: its multi-plate clutch pack binds or slips, and twelve YouTube channels and every forum stream name it the 958's weak point. The other faults rated likely on a 958.1 V8 are the glued coolant pipe letting go at the thermostat housing, air strut leaks and compressor burn-out, worn spark plugs and failing ignition coils, and heavy brake wear with ABS and pad-wear sensor loom faults.

How often should the 958 Cayenne transfer case fluid be changed?

Porsche's schedule says 240,000 km or 16 years, but owners and specialists change it far sooner - typically every 30,000-60,000 km (Rennlist owners every 15,000-20,000 miles, PcarWise 40,000 miles, eCarGuides 120,000 km). It takes Porsche transfer case fluid 000 043 305 63, 0.875 L per the owner's manual, so buy two 850 ml bottles. The car must be level: remove the fill plug first, drain, then fill until it overflows, with two new plugs 955 301 115 01.

What oil does the 958 GTS 4.8 V8 take, and how much?

Oil with Porsche A40 approval: SAE 0W-40 for all temperatures, or 5W-40 or 5W-50 above -25 °C. Australian examples are Mobil 1 Triple Action 0W-40 and Castrol EDGE 0W-40 A3/B4. It takes 9.0 L with a filter change (8.5 L without) per the owner's manual. There is no dipstick - read the level in the instrument cluster - so fill about 8.5 L, run it warm and top up in 0.25 L steps. Buy 10 L.

Can you service a 958 Cayenne GTS at home?

Largely, yes. The naturally aspirated 4.8 V8 is workable from the top: oil and filter, spark plugs, ignition coils, air filters and transfer case fluid are all rated easy, and coolant, differential fluid, brakes and air struts can be done with care. The 8-speed Tiptronic fluid change needs a special tool. Leave transfer case replacement to a specialist, and walk away from a car with an oil leak from the timing chain cover.

Does the 958 Cayenne GTS have air suspension?

Australian S and GTS cars came with air suspension as standard (option code 1BK). Elsewhere the GTS came on steel springs with PASM, with air as an option. Air strut leaks and compressor burn-out are rated likely on a 958.1, so assume it's part of the ownership cost.

How do I find what options a 958 Cayenne has?

Look for the option sticker under the boot floor near the spare wheel and in the service book - on 958s it's hit and miss, so check both. Failing that, give the VIN to a Porsche Centre or a specialist with PIWIS and ask for the factory equipment list. The VIN itself doesn't contain the options.

What are the 958 Cayenne option codes for PDCC, PTV Plus and Sport Chrono?

PDCC is 0AW, PTV Plus is 1Y1 and Sport Chrono is QR4. Air suspension with PASM is 1BK, and Burmester sound is 9VJ.
