I don't have access to a vag com just yet but I may be able to find on locally (slc, utah) but here's what happened. I was pulling up to a stop and all of a sudden it sounded like a valve opened and was dumping air. It didn't sound like a leak or a burst bag, I've had both of those before. Got out and both fronts were still at 2 or 3 I forget, but both rears were completely empty. Since then the fronts have lowered to their bump stops as well and none of them have filled up since. Anything in particular I can try to fix my problem or at least get me closer to knowing what's happening?

MrKid

Does the compressor run when you start the vehicle?

What do you have for dash and height control lights?

yea, you're gonna need that vagcom to scan for codes and go through the output tests
and while its doing the tests, check for leaks

It does run and I get the orange suspension light in the cluster flashing. The lights on the level buttons seem to be acting normally. It sounds like it is just blowing air somewhere towards the back. I'm going to pull it into my warehouse later today and check it out.

01577 compressor getting hot from running too much, check for leaks (never hurts to so this regardless)
00774 that sensor died, replace it; new from the dealer is going to be close to $200, source a good used one if you can
01400 your going to have to reset the ride heights, search for '402 mod' to get the proper procedure
01771 should go away when you address the 3 problems here

IsaacD2

Cool, Thanks a bunch. I'm pulling it into the shop today to swap out my cv axles so i'll look at that sensor also.

Sounds like one of your soilionds valves block has come lose or come apart and is letting air out

Sounds to me like you lost a Pneumatic supply line to the rear. You can buy a 50 ft roll of the line on Amazon for about $25 and its enough to do the whole car and half of another car. while you are at it go ahead an order a new compressor piston ring from Bagpipe Andy in the UK. Be careful when you disconnect
the Plastic line from the distribution block to capture all of the old fitting pieces. The Color of the line sold by Amazon is black. The color doesn't matter once the vehicle leaves the factory. I've seen far more plastic line failures than Strut or Distribution Blocks go bad. And yes I've changed them all for no reason what-so-ever. Bagpipe Andy also carries spare compressor Piston Assemblies as well as Replacement Compressor Cylinders for the WABCO Compressors.
Dixon 1091P0401 5/32 Pneumatic supply line At Amazon.com they even sell the ferrules and nuts as well

My 2002 allroad has a solid orange suspension warning light, except very occasionally it randomly flashes when the vehicle is in motion. The code is 00776 which indicates a fault with the front left level control sensor. That has been removed from the vehicle but no issue such as corrosion is visible. Is there a way to bench test the sensor with a multimeter? I do not have a wiring diagram. Is there a trick to disassemble the connecting plug so it can be checked for corrosion?
Thank you for any assistance.
