Mine cluster chime has failed also. Local dealer suggested I call local speedometer shop, he informed me that its a difficult fix and was not interested in repairing.

This has left me out in the cold and sometimes with my turn signal still on.

Any help would be appreciated.

Sounds like the compressor piston seal is worn. Mine was not really making a noise but it was constantly working to keep a certain PSI in the system.

See my post above, go to the VW dealer and buy the rebuild kit. Save the money and spend 1 hour to fix your problem.

guys,

i have a cayenne turbo 2005 with techart lowering module installed

the system was working great. kept it in the LOW mode and when i lock it it drops to LOADING.

then all of a sudden about 4 months ago when the car raises itself back up to LOW level the air compressor turns on (as expected) but much louder than i originally remembered. it also stays on for quite a while and cylces more often when i am driving.

i took it to the stealership who were no help and said the sound is normal, confirming this with another CTT. since then i have been driving with it in NORMAL mode and the air compressor rarely cycles as it is not raising/lowering constantly but the noise is still loud when it does.

any ideas why this is happening? its frustrating as a i like to drive in low level.

do you think this air pump repair kit will correct the noise?

I do have the instructions from WABCO and would like to scan an attach to this posting but am new to the forum and could use some help. Do I just uplaod the file in my post here?

Thanks for the great DIY help!

Bought a 2004 Turbo and I immediately had the "Air Suspension Faulty - Workshop" error light. Of course I took it to the dealer but the light did not come on while at their shop. But as soon as I would drive it - I would get the fault. Ran across this posting and thought I would rebuild before paying for a new compressor.

I bought the part from a local VW dealer for $170.00 USD and spent an hour following isakpede's posting. Very easy and immediately solved my fault.

My kit from Wabco contained a piston ring, two Torx bolts for compressor head and an o ring seal. No elbow is included nor did my unit need one. It was in good shape.

Thanks for the great DIY help!
