  1. Another possibility is the transmission lever position switch module on the transmission itself. It senses what position the transmission lever is at.
  2. P2281 is a leak between the turbocharger and the throttle valve. It may not be the turbo charger that is cracked, but could be the ducting from the turbo to the throttle valve. If it is leaking ducting, it should not be hard nor an expensive issue to rectify.
  3. The temp control servos are located on the rear ac unit located in the rear left luggage component as Clarksong has noted, Getting to the right servo should be easy once you pull the left side lining of the cargo off, as opposed to the left servo, you have to unbolt the ac unit and tilt it inboard to get access.
  4. I had the dealer do mine. Mounts can be changed without major component removals.
  5. Engine mounts sag after a few years transmitting vibes through to the chassis. Changed mine 12 months ago, vibes were gone.
  6. The attached wiring diagram shows the fan power coming from the 60 amp fuse F1 and the 30 amp fuse F10.
  7. You could always get access to the rear a/c unit and inspect the temperature control servo/flap, ensuring it is not stuck in the full heat position.
  8. Good that it's not the transmission hardware. Hopefully it's an indication fault only.
  9. The display with the all the PRND lit up can mean your transmission is in a Limp mode. (Degraded mode). You need to get the codes read to determine what is causing the fault.
  10. Any codes? I would check / reseat the connector on the transmission control unit under the right front seat. Also note that there was an issue where transmission fluid can wick up the cable and contaminate the TCU connection.
  11. My research reveals that the Porsche recommended oils are non synthetic. Using alternative synthetic oils is not recommended as it may affect seals in the transmission that have been subject to initial mineral oils. This may lead to possible leaks from the transmission. Sound maintenance philosophy is to use the Porsche recommended oil and change it more frequently, every 40,000 miles.
  12. If your going down the GPS antenna route being the issue, one would expect the Nav accuracy on your system would also be compromised. Is this the case?
  13. Take the battery out. Blow air from a hairdryer across the fob on low heat for five minutes. Reassemble fob. Good Luck.
  14. Definitely sounds like your defect is with the wiring under the water box. How difficult is it to lift the water box and check the wiring?
  15. Do your brake lights turn on when you press the brake pedal?
  16. This is a common problem with the pumps. There is a valve for each pump that connects the hose from the pumps to the exhaust manifold. The valves fail open and allow hot exhaust air to reach the pump, destroying the foam etc. Check them to ensure your new pump doesn't prematurely fail.
  17. Secondary air pumps have been known to fail. The impellers disintegrate and prevent the motor from turning. You could try electrically disconnecting the pumps and replace the fuse to see what happens.
  18. Can you list what year and model along with the faults that your Cayenne had.
  19. Without codes we are guessing, but it sounds like your transfer case servo motor is not working. Check the fuse for it, if ok then it most probably will be a servo motor replacement. If the servo requires replacement, it may also need a controller replacement to match the new version motor. This was common for the early model Cayennes. If it is a faulty servo motor, it will be putting the transfer case in the wrong gear position. This will result in excessive loads on the drivetrain. Servo is about $1000 AUD and the controller is another $950 AUD. Labour will be $1000 if done a
  20. Good to hear that it is fixed. Strange though, as I have heard it said that this cooling system was supposed to be self bleeding.
  21. Was there a specific time or event that made the temperature sit higher than normal? What temperature did it display when you originally bought the car?
