    Perhaps there is a leak in the system, a shortage of refrigerant shut the compressor for safety reasons off. Let check the quantity of refrigerant (900gr./950gr.)

    At PTEC interpretation, i can add nothing. Hope it helps.

    With the doors closed, the windows should go up to the fully up possition after closing the top. It is possible to program the control box with a PIWIS diagnostic tool, closed with ignition on, closed while driving 5 Km/h and always open.

    Check if the blue cap part # corresponds with the last up date, if not, replace. The traces on the bleeder (black) cap would also have to disappear.

    I would like to remind you that it is not possible to remove a Tiptronic gearbox separately without silly things to do on a 996 with M.B. Tiptronic. On a 996 with a Z.F. Tiptronic on the other hand, there is no problem at all.

    Check if the third brake light is still working, on a 997, the left brake light is directly controlled by the brake switch, the third and right brake light are controlled by the rear control box, via the brake switch. If both, the third and the right are out, it could be more than a socket.

    As Loren said, the ground strap is located under the carpet, just in front, right side of the seat.
  8. RFM
    Yes, the crank position sensor and the system relays are the first suspects IMHO, their values are highly dependent on temperature, engine temp. and heat generated by system power consumers as well.

    On the top rear of the engine, starter motor area, you find a plastic support with 3 water hoses you have to remove in case of a light alloy water pipes install. The 3 water hoses are side by side in the support ready to connect on 3 water pipes, side by side, behind the engine. The order is not logical (most left on most left, middle on middle, etc.) two of the hoses are connected wrong, they must be crossed. This situation is responsible for the overheat problem you describe. Take a look in to an other Cayenne for the right order. Hope it helps.

    A defective "new" coil is possible, if the issue stays away within a week or so, it should be OK.

    Vario Cam Plus (valve lift) engines are suffering every now and than with a defective valve lifter (stuck in full lift or minimum lift). This problem indicates a "misfire code" let check that out first.
  12. RFM
    It can be different things as temp. sensors, servo motors, etc. A diagnostic tool should help to read out any existing fault code.
  13. RFM
    If you cant find any trace of water in the engine oil (only slight traces of oil in cooling water) after several proper checks and the engine runs perfect without restriction of any kind, and the car is a Tiptronic, do not hesitate to check the ATF and Tiptronic oil exchanger/cooler as well, it's very uncommon but still possible under some circumstances. Once again, it's only a small chance but you can seek for ever before discovering the problem. Therefore it would be a shame to dismantle an engine. Hope it helps.

    Cars with "saddlebag" formed fuel tanks and fuel pumps mounted in the middle and on top of the tank, as Turbo and C4/S, needs recalibration by the dealer using a PIWIS diagnostic tool. This type of fuel tanks must always be filled up to the top when empty, a partial fill (10 liter) will cause the problem what you have now.
  15. RFM
    Disconnect the ground strap in front of the driver seat for approx. 5 minutes and try again, if the system still does not work you will need a PIWIS diagnostic tool. Hope it helps.
  16. RFM
    You can always try with key #2, or replace the battery inside the remote, to start with.
  17. RFM
    A cracked diaphragm spring belongs to the possibilities, unfortunately the gearbox must be build out to verify this.
  18. RFM
    Sounds as a snapped window regulator cable, a replacement will be required.
  19. RFM
    US cars parts as control boxes, door locks, remote controls, etc which are directly connected to radio frequencies (Hz) are different than ROW cars, i don't know for sure if it will work, but you can try.

    1) Quick speaker check = ignition on - lights on - ignition off - the speaker should work now. 2) Quick park assist check = ignition on - gearbox in reverse - does the reversing lights work ? - if not, check fuses/reversing light switch - if yes, use a PIWIS tester.

    The rubber shrinks over time, the best is to replace. Just push in with the help of a small amount of silicone spray.
  22. RFM
    I forgot to mention the pliable part of the oil filling pipe, there are cracks after repeated use and over time.
  23. RFM
    The codes means engine run too lean on both cylinder banks ( DME on rich threshold), most common problems when working on the filter and intake, are air leaks between MAF and intake manifold and defective MAF.
  24. RFM
    The engine did not reach range2, 91 times at 3140h, but 91 ignitions, which is a very short duration, i would not worry about it.
  25. RFM
    The AC display unit is the only control box (computer), the sensor on top of the dash is a solar (sun) sensor. You really need a PIWIS tester to read the codes and values of each part in the system. A program error in the AC or other CAN-BUS related control boxes and devices (PCM, etc.), can cause similar problems as described.
