Air suspension compressor
 

I've been spending a fairly significant amount of cash bringing my 2003 '8 (3.7l) back up to standard as several problems have arisen in recent months - the car is just too nice not to spend the dough. I'm left with just one outstanding issue, though - the compressor for the air suspension is getting rather weak and noisy.

The local indy garage (whom I've been using for years - they've been very good) advise that the compressor is a very expensive part at a little over a grand including the VAT. I don't really want to spend that if I can avoid it, so I'm left with the option of aftermarket or used (the latter from our forum sponsor).

This is the aftermarket option I've found (with a 2-year warranty):

Anybody used them, or have any other advice? I know that A8parts are an extremely conscientious supplier and aren't going to send me a badly worn pump, but on the other hand, I anticipate keeping the car for a while yet (she still drives like new, despite a few minor battle scars), so a new part would seem like a good idea.

Look for the bagpipingandy rebuild kit on Ebay.

I had this fitted to my compressor 3 years ago as it was weak and generating fault codes. I've been code free since that day.

Thanks for the tip!

Yes. I just bought a compressor from them a couple of months ago. It was a wabco part that appears to be identical to the audi part I took off. Other than the sticker. Working great for me...

Thanks - it's good to have options :)

Ive used this company and found them to be good -

When you return your old compressor they will also give you a £25 refund and they guarantee the units as well, when I took mine off this one looked identical.
I used the bagpiping Andy kit to try and fix the old one first but it didn't last very long. The old compressor was putting out 7.6 bar instead of 16 bar that the new one puts out!

I have read a lot of good stuff an other Audi forums about bagpipingandys kit, seems to be well regarded+++

Thanks again for the advice guys!

I would recommend the DIY repair option. When I bought the car, the suspension wouldn't raise at all. I removed the compressor and replaced the piston ring and it's been fine since.

The job only takes 1-2 hours overall and total cost was around £15. The hardest part was removing the bolts on the compressor cylinder as one in particular was in tight (snapped a hex key in half trying to remove it!)

Thanks for the suggestion, MatthewH, but whichever way I go, it's going to have to be done by my local garage as I have MS and no longer have the strength to work on my own cars, sadly.
