    The batteries inside the sensors cause reading problems after about 4 years, anyway, 4 defective sensors at the same time seem very coincidental. I would check it out with a PIWIS diagnostic tool, look for fault codes first, do a reprogramming if there are no codes stored.

    Maybe i misunderstood, but the cylinder heads on the pics are not VarioCam Plus.

    The window problem is caused by a malfunction of the window motor/control box combination, unfortunately, a replacement is the solution.
  4. RFM
    I would clean up the connectors on top of the oil pressure switch to start with.
  5. RFM
    A reasonable labour time to replace the cable by a experienced person is approx. 1.h 00 for a manual transmission and 1.h 30 for a Tiptronic.
  6. RFM
    Cracked pressure plate (diaphragm spring) will happen occasionally also.

    There are several "air sensors" included in the system, mostly behind the dash. Let the system read out with a diagnostic tool, otherwise it's guessing.

    The clicking sound is caused by the temp. flap/motor combination, this happens not completely noiseless. Since the car is still covered with warranty, i would check it out for sure and peace of mind.

    The AC condenser fan is also the cooling fan, you have to remove the front wheel on the same side of the defective fan. It's up to you to know which fan is defective (fault codes), left or right.

    The catcher (hook) is located in the trunk, on the floor.
  11. RFM
    The oil level sensor is located on top of the engine bloc under the intake manifold, approx. in the middle/right side.

    Yes, the front and rear window seals are changeable without removing the windows, they just pull out. They should even out first before the window can be removed.

    This is an easy question, separate the electrical part of the lock unit, try if the key now works properly, if yes, the electric part is bad, if not, the lock unit is the culprit.

    The engine room ventilation fan may not always on, certainly not with cold engine, some possible causes are: DME error, DME poorly programmed, sensor failure, wiring/connector failure. I would be inspected the issue if i was you.
  15. RFM
    The chart is correct, the rest is wishful thinking.

    PTEC has it right, it comes with the allu. door sills sold as spare part, they are used to clean up the paint, after removing the old OEM standard plastic door sills, then the allu. sills are glued on the clean paint.

    Be especially careful that the correct tyre pressure is set, and the tank full of fuel !!!!
  18. RFM
    That kind of sensors have no direct contact with cooling water, it is certainly not the sensor, rather the tank it self, as Loren mentioned.

    If all fusses are OK, i would start with a brake light switch check/replacement, the switch will solve the three problems, PSM/ABS, brake lights and Tiptronic park lock.
  20. RFM
    They probably mean the secondary air system, a conventional EGR system is not present. It is important, in all cases, to note the fault code(s).

    http://www.renntech.org/forums/index.php?/topic/32649-the-mod-that-increase-40-plus-miles-per-tank-to-my-cayenne/ Read this topic, it may answer your question.

    Looks normal to me, at slow speed, hot engine, and under the circumstances you describe, the transmission use the second gear, with W.O.T. the Tiptronic will switch back to first gear and stay there till the max. RPM is reached or the accelerator is released. You can (let) read out the fault memories with a diagnostic tool for peace of mind.
  23. RFM
    A second important spot to look at are the air entrance and exit in the front doors, sometimes the air exit holes in the doors do not/bad match with the air entrance in the B pillar (loose grill, damaged seal, door badly adjusted) You can check it out if you put some tape on the dashboard air exit/connection between door and dashboard, so that no airflow can pass through the inner door air channels.

    The whistle is caused by air pressure inside the car, the pressure escapes through small cracks and holes which are in direct contact with the outside air (door and window seals). Behind the removable trim, left and right, in the trunk are two ventilation grilles which are covered by a rubber membrane, make sure the grilles are free of dirt, junk, etc. cut away a small part of the membrane such that direct contact occurs between outside air and car interior, the pressure will escape without that annoying whistle.

    There was a DME update about 3 years ago and a intervention in the fuse box for some countries.
