i have a Porsche cayenne of 2006 and have some problems with the air suspension. i changed all seals and the airspring in the front and yesterday everything was ok. today i went to the car and the airsuspension in the front was down again. i start the engine and touched the leveler  to raise up the car. i heard how the compressor was working but the front suspension stay down. after a while the light for the ABS and Traction control went on and the speedometer went up to 90mph. the ABS light and traction control light stay now on and in the dash comes the message PSM failure. if i use now the leveler to bring down the car or i would try to raise it up nothing happens not even the compressor comes on. i disconnect the Battery for 5 minutes and start the car again. the compressor work but only a very short time  and the car don't raise up. i can push the leveler in every position and nothing happen. i hook up the VCDS and choose the Touareg 7L from 2003-2006 but i can only read out the ABS and it show ABS wheel speed sensor front left and both in the rear implausible signal also it showed tiptronic switch F189 implausible signal. had that something to do with the air suspension? do i need hear the OEM Software of Porsche and if it is so can someone PLEASE send me a link where i can buy it? i changed 2 years ago the valve block. can i change the lines from the valveblock from the front to the rear that i get air pressure on the front springs to see whether a leak is there or how i can get air in? if someone have technical information about the air suspension Please send it to me and i will donate again.


many thanks for every help

      i have a 2006 Porsche Cayenne 4.5 V8 Bi-Turbo.
      after i parked the car overnight the front suspension goes down and the rear stay up. the display show nothing about a failure. if i start the engine the front goes up and after a short while i hear that by the passenger side airfilterbox the air get short release again. the whole suspension is working perfect only that the fron goes down over night. i sprayed all lines and airbags in with dish liquid to see whether there is a leak but i didn't find anything. can it be that the regulation valve is not proper working or the little valves on the strut?
      please help!!!

      Just figured i would share.  Christmas Day heading down to see the parents i had a loud BANG come from the front left.  sounded like i had a rock kick up under the car or something.  Completely flat, fresh pavement, so no bumps of any kind around.
      Anyways i didn't see anything come out the back of the car and no warning lights so i figured i'd keep driving.  Got to my parents, and as i'm pulling in i get a suspension warning.  Weird, still same ride height so enjoyed the day with my family.
      Coming home, the car was at the loading height in the front.  definitely sitting on the bump stops.
      Got a replacement from Germany through Miessler for 289 with the new o rings.  A STEAL considering sunset wanted 1200.
      replacement is pretty easy.
      Something to keep in mind.  take a look at the aluminum cover that split on me.  Mine had cracks for a long time, but never really though anything of it.

      Hi Guys,
      I am owner of Cayenne S 03'. From few days an error message pops-up on car display "Air suspension warrning". I connected it to the computer and it is shown as P1400 - control position not adjustable.
      My observation are the following:
      1.There is no problem with going for higher position (for example from normal to terrain).
      2. There is no error while I am riding on terrain level and not exceeding a speed which is lowering the car. After exceeding this speed car is starting to go down and error pop-ups.
      3. Error is shown only while lowering the car.
      4. Front suspension is lowering without any problem, it applies only for rear.
      5. When error pop-ups I can see that front suspension is much lower then rear.
      6. It only only applies to front/rear relation. I can not see any difference between right/left.
      Local workshop pointed it as a compressor problem, but in my opinion it is rather some kind of valve responsible for releasing the pressure then compressor, as I can not see problems with getting car higher. Just with going for lower position.
      I will be very thankfull for your opinion as a specialists, as nearest Porsche dedicated workshop is like 300km from the place where I live.
