    And perhaps weird shift phenomenons (Tiptronic) because the final ratio is changed.
  2. RFM
    Coolant is the answer.

    I would first check what exactly is defective, accumulator, slave cylinder/valve block/power unit, power steering pump or a fracture/deformation in the clutch system itself, an accumulator is what it is, a spare storage of liquid under pressure, to remain auxiliary power for approx. 10 clutch pedal movements with the engine shut off. In other words with the engine running receives the power cylinder/valve block, on the gearbox, always directly pump pressure. It's important to know for sure what's broken before replacing parts randomly. It is only the rear part of the hydraulic clutch system (accumulator and power unit) which is under high pressure, the front part (main cylinder, clutch fluid canister and clutch fluid line to the rear of the car) works like a regular Carrera. The pedal box parts and the main cylinder will go defective over the long term, they are not designed for long time use without clutch power assistance, they can't hold the much heavier pressure that the driver should perform on the pedal.

    Is the correct fill level held? With for example 200 gram too little, he will still function but should be circulated more to maintain an acceptable cooling capacity. PST and PIWIS diagnose not everything, i would advise you to contact a AC specialist or a experienced dealership.
  5. RFM
    Certainly not on AC systems with a compressor equipped with an electromagnetic clutch (986/996/987/997), unless you are at the equator, the temp. set to LOW and the convertible top is open. The system will clearly need to be further investigated if this is not the case.

    The front and rear doors act in the same way, the childproof rear door locks are mechanical and are independent from Kessy system.
  7. RFM
    More or less, point B on the pic is the Cayenne AOS, replacing the tube is the proper method, repair with glue is looking for trouble IMHO.
  8. RFM
    Cayenne, 987 and 997 use no longer TORKX, which have 6 points. They use KLANN KL-4064-601 K which is a set of 9 small keys, they look the same but have only 5 points. The reason they give is that the MAF is available only as a unit with the housing, just like the older 964 and 993. The MAF should be calibrated inside the housing according Bosch, but may also commercial reasons. KLANN keys are rather hard to find.
  9. RFM
    As "wvicary" already indicated, only a PIWIS diagnostic tool can help you out in a decent and quick way. Kessy system can cause problems for sure.
  10. RFM
    A simple scanner can read no other codes than emission related codes. Since the unit wont turn on, i would check the fuse on the rear (back side) of the unit too.
  11. RFM
    The pipe is a part of the crankcase ventilation system, there will always be an oil residue present by precipitating oil vapors. The yellowish creamy fluid is a mix of these oil residue and water vapour from the combustion which precipitates as water drops on the coldest parts of the engine, remember that a cold engine get soaking wet inside until fully warmed up ( approx. 10 a 15 Km normal driving). This is therefore a normal phenomenon.
  12. RFM
    It is not the new cap that broke the coolant reservoir, it is the old cap which is defective and therefore loose cooling system pressure, no pressure no leak. Driving without pressure in the cooling system increases the chance of overheating significantly.
  13. RFM
    The code you mentioned is a timing issue, not a misfire code, either a camshaft sensor problem or a stretched timing chain/worn guides IMHO. This happens sometimes.
  14. RFM
    A broken wire inside the cable, near the shock absorber, where the cable attachment in rubber is located would sometimes occur. Cut the cable and the rubber mounting open in the longitudinal direction with a razor blade, the protective cable casing and the rubber are vulcanized too tight, the inside wiring will crack by several up and downwards wheel movement.
  15. RFM
    There should be a note glued on the driver side B-pillar, 18 " front 2.5 Kg/cm² rear 3.0 Kg/cm² measured on cold tires (for example: in the morning, car not driven yet)
  16. RFM
    Maybe the cap is not properly installed or the filler neck tube cracked, both are pretty common. Better to read the codes first as suggested by Loren.
  17. RFM
    997/987 use no longer a locking pin, i believe that you have to push the button forwards, turn full to the left and than pull the button off at the same time, i cant check it for sure cause the car is not here for the moment.
  18. RFM
    DFI engines tubes are different in design and dimensions, maybe they are more confident in it. The older Cayenne's kept around 100.000 Km.
  19. RFM
    Hard disc driven Porsche navigation systems use a code (payable to the dealer) and a PIWIS 1 or 2 diagnostic/programing tool to finish the job.
  20. RFM
    The left and right longitudinal tension cables are hold by a transverse elastic ribbon, which pull the cables slightly to the middle of the car so that they fit in the plastic trim instead of over the trim. Probably the ribbon broke, take a look with the roof halfway, between the textile roof layers, the ribbon can be sewn by hand.
  21. RFM
    The factory has never changed the water pipes from plastic to metal ones during the production, these were intended only as the ultimate upgrade for V8 up to MY06 with indirect fuel injection. From MY08 V8 with direct injection, they are still made from plastic, but a different design. Maybe it will surprise that MY07 is missing, that's because MY08 (VIN) is delivered early 2007. This fact will affect the purchase/sale price in some countries depending on whether the VIN MY or the date of entry into service is applicable, if the purchase prise is linked to the entry into service date there is no problem, in the other case (per MY) the car is too expensive under certain circumstances, for example MY08 delivered early 2007.
  22. RFM
    The secondary air pump would indeed be eligible for replacement, just as your tires shown in the video :o .
  23. RFM
    It may be that your dealer proceed to replace the plastic master clutch cylinder (if fitted), there are some problems with in some circumstances.
  24. RFM
    The points you mentioned are all possible, however, random replacing parts is very expensive at the end. Use a diagnostic tool or go to a dealer to read out the fault codes first, according to the codes and some measurements it's more possible to narrow your search IMHO.
  25. RFM
    Usually the wiper motor/control box unit is the culprit, anyway, its better to check the fuses, wiring's and connectors first and the moving parts of the mechanism as well to be sure.
