I did the Air Compressor rebuild this weekend using bagpipingandy's kit. It was a breeze to do the rebuild. It was harder and more time consuming taking the compressor out and putting it back in.

Used the Arnott video on replacing the compressor:

Took about 2 hours.

Driving it around for a couple of days now and I haven't seen the "Air Suspension Fault" message yet.

Woo hoo! On to the next task!

 

Were you able to pull the codes before undergoing this exercise by any chance?

 

Congratulations on your rebuild, anindyam! For others who determine that their compressors need to be rebuilt, I took photos and put together some supplemental information at the links below.

Cheers,

Don

Lagonia - I don't remember the codes as the issue was flagged a long time ago. When I used to go to the local dealer, they said there was a short in the wiring. It didn't happen often enough to warrant a fix, so I chose not to pursue.

My local indy Jag shop (who I trust more completely) said the codes show the compressor isn't able to pump out enough air in the timeframe required, so I needed to replace it. The only drawback to my indy is they don't put in procure rebuilt or 3rd party parts, only Jag parts. So their repair was going to be >$700 for the Jag compressor, or I could buy a used, rebuilt or new Wabco and they would put it in for the labor costs.

But thanks to this forum and the numerous threads on Air Suspension Faults, I discovered bagpipingandy's kit. To me it was a no brainer - get the kit ($30) and spend some time getting it out and rebuilding the existing air compressor. If it works, great. If not, I'm out $30 and some time.

Again, can't say for sure it worked, but I haven't seen the error message appear since then.

 

You oughta get this pinned!

 

Thanks anindyam,

I hope to find time to actually repost the photos and captions here if edobernig doesn't beat me to it!

Cheers,
