Common Symptoms

If you experience these symptoms, your Porsche Cayenne (955/957/958/9Y0) may need air suspension repair:

PASM / air suspension warning light
Vehicle sitting low on one or more corners
Rough ride on highway — cannot raise to off-road height
Audible compressor grinding or not cycling
Slow sag overnight when parked

Why This Happens

Understanding the root cause helps prevent future issues:

1.Air compressor motor overload (tries to compensate for leaking struts)
2.Air strut rubber bladder deterioration (age and ozone exposure)
3.Valve block solenoid failure (directs air to each corner)
4.Desiccant in air dryer becomes saturated
5.Strut top mount bearing wear (separate from air bladder)

Frequently Asked Questions

Can I convert my Cayenne to coilovers instead of fixing the air suspension?

Yes. On 955/957 Cayenne (2003-2010), converting to quality coilover springs is a legitimate option when multiple struts have failed and the compressor is also going. The ride quality difference is minimal for normal driving. The PASM system can be left in a static position. We perform coilover conversions as well as air system repairs — we'll help you decide which makes more sense for your mileage and budget.

My Cayenne compressor runs but the car still sits low. What's wrong?

If the compressor is running but the Cayenne still sags, the leak is in the air struts, valve block, or supply lines — not the compressor itself. Running the compressor to compensate for a strut leak eventually burns out the compressor motor. Diagnose and fix the leak source first. A PIWIS 4 scan helps isolate which corner is leaking based on pressure loss rate.
