Hi all I new to cayenne bought the truck a few months back ,fix all back up so far great truck , every time I start the car air suspension fault workshop,I've done the compressor piston ring and still I get the code on the selector inside It shows the different selection in the cluster but it doesn't raise or lower sometime I drive the back bouncy around real bad and rides horrible I don't have access to durametric so idont have any codes .thanks

You may still need Durametric or Vagcom to clear the stored faults in the Controller to reset it.

I have vag.com but it doesn't read the suspension it only reads the engine

Try to go to the Level Control Module in Vagcom and it should work if you have the newer version. The Audi A8/Q7 and the older Allroad all have a very similar version of the Cayenne/Touareg Air suspension. Actually, the parts and modules are all the same manufacturers, just model differences. I have both Vagcom and Durametric and use them almost interchangeably.  The Vagcom works better on the Porsche than the Durametric works on the Audi.

I was able to make an adapter to get the vagcom to work and I get this code and erase it and it comes right back not sure where to go from here I also notice I can't lower or raise the truck .thanks again

I was warned by Owen at Durametric not to use vagcom on porsche as it can cause can bus faults and display false codes.

have you replaced the air pressure retaining valves on 4 corners? about 80 bucks each. need special tools to take them out. front 2 are easy. back are hard but doable.

when they have problem car won't lower or raise. 

I talked to the local dealer parts guys and they replace those frequently.

@royxaxa thank I'll do that and I'll update my results thanks for your help

If the fault shown in post #5 is accurate, then it looks like the sensor at the spare wheel filling port might be faulty.  That's the one under the front passenger seat.
