I just pulled it all apart to check fuse in back of PCM and wiring. PCM has power and everything it needs. It is just dead. Tried all the methods to reset unit but guess it finnaly took a **** on me. Thanks for the help. They were factory discs. It had been acting up but I tought it was just becasue the navi discs were out which I have seen happen before.

I just got a 2006 Turbo S, that was missing the nav dvds. It kept displaying a PCM temp cutoff message and turning off. I would reset the PCM it would be fine for a few starts. Now I tried to update the discs and it was not taking th software update. Then I reset PCM and now its completelty dead. U guys think everyhting is toast or what. Any help or suggestions is appreciated. Prolly time for a Kenwood head unit.

What are you guys seeing for fuel pump failures on your turbo cayennes. I have 100k on mine and taking a 2500 mile road trip next month and was gonna throw a new set of fuel pumps in the pig because I didnt want to have a failure on the road becasue that is my luck, or I could just bring them and change on the side of the road if need be, they are so easy to do. Thanks guys.

If you verified that it has good pressure and warning light is still on, prolly a sending unit. If you have a multimeter you can check the signal from the oil pressure sender to DME to make sure it has a good signal or not. But prolly just easier to throw in a sending unit and if that dont fix it then you can really dig into it. If it dosent let me know and I will tell you exactly how to check circit and send u diagram if need be.

If you have service manual you will see that the spec for the fluid is Mobil 3309. Mobil 3309 is made the Aisin transmissions in our cars, which is same as Toyota IV. You could actually use pretty much any good multi vehicle fluid or universal synthetic becasue they meets the same specs, but I would stay with the Mobil 3309 or Toyota IV. The fluid is not synthetic. These are the same transmissions in the Touarags and you can see that Mobil 3309 is used for that part number. I am a tech and have used the Toyota fluid in about 5 Cayennes / Touaregs. Save youself some money guys. Here is from Mobil site: Mobil ATF 3309 Mobil ATF 3309 is an exceptionally high-performance lubricant that meets original equipment manufacturers’ specifications for use in certain slip-controlled lock-up automatic transmissions manufactured by Aisin AW Co.

Meets key OEM requirements: For many Toyota, Lexus, Volvo, Saturn, VW and other imported and domestic vehicles where Aisin transmissions are used. Meets key Type T-IV for Toyota/Lexus vehicles Mobil ATF 3309 is recommended for use in transmissions made by Aisin AW requiring a fluid approved against Type T-IV, JWS 3309, GM 9986195 and Audi G-052-025-A2.

These outstanding performance capabilities translate into significant operational benefits, including: Excellent lubricating characteristics for quiet operation and smooth shifting in approved transmissions. Controlled friction properties for smooth and efficient transmission of power across all normal temperature ranges. Helps to control transmission shudder and provide excellent vehicle driveability. Helps to extend transmission life based on excellent wear control. Long fluid life based on excellent oxidation resistance. Excellent viscosity stability (high viscosity index) to help assure adequate lubrication without excessive thinning in severe high-temperature service or thickening at low starting temperatures. Resistance to foaming. Superb protection against rusting and corrosion. Compatibility with transmission seal materials. Applications: Mobil ATF 3309 is recommended for use in transmissions made by Aisin AW requiring fluids approved against JWS 3309 or GM 9986195. It is also recommended for service fill applications where Toyota T-IV is needed. Please refer to the owners’ manual for proper fluid requirements. Automatic transmissions should be checked for proper fluid levels at regular intervals, and the fluid should be changed at manufacturer-recommended intervals. However, this may vary due to your vehicle's operating conditions. Some manufacturers recommend more frequent changes of transmission fluid under severe driving conditions, such as heavy traffic, hot weather and trailer pulling.

Yup gotta have it running and in neutral. Have fun. I just did mine. When you fill it up you dont have to buy the Porsche fluid for 30 bucks, go over to a toyota dealer and get some Type IV fluid, exact same stuff for 5 bucks a quart. Or you can use Mobil 3309 if you can find it.

For the trans just get Toyata IV fluid at the dealer, around 5 bucks a quart. You dont want to put gear lube in the transfer case!!!! It takes VW G 052 162 A2 which is a synthetic transmission fluid. You could also use a synthetic ATF that meets requirement like mobil 1 or Amsoil. OR you could use Esso LT 71141 which is ATF used in some BMW's etc. All will work fine. 75w-90 synthetic gear lube for front and rear diffs. Ill post some pics up I just did all my fluids. Good for another 100k.
