My 04 A8 seems to be sitting about 1/2 inch lower on rear right suspension. Barely noticeable and it seems to drive straight though. Has anyone experience something similar?

Thanks-

Probably caused by the WABCO/ATE ELM system sensor at that wheel end. Compare it with the rear left sensor. Look carefully at the lever mounting as well as the sensor mounting. A fastener may be loose or broken

with VAG COM, either to a generally lower setting or to where it should be consistent w/ the other corners. Search archives for the how to's.

This assumes you are out of warranty and free repair.

I had a similar issue with my 04 A8L. You can find some message traffic on it early in this forum. Say late 03-early 04. It showed up as a "sag" in the right (?) front suspension. I finally became convinced that though it looked pretty dumb..."it don't hurt the runnin' of it none". Seems likely that all the pumps and controllers level out the flagship when it starts up and moves.

Going into the fifth year the A8 remains a fantastic car with no peculiar handling or tire wear due to sagging at rest.

YMMV of course but I hope your results are as good as mine

Hi ZRH,

Is your suspension air compressor the original one?

Spread that dead body in the trunk more evenly...

ZRH

Yep it is the original compressor and valving. The car has had virtually no warranty work beyond trunk hinges. It is a very low mileage car....and I hope I am not risking the Wrath of the demons of Ingolstadt by mentioning its trouble-free record.

I vaguely recall mention of suspension sensor replacement as a seaport update, but my A8L had that and still sagged. Maybe still does but perhaps it would look odd to me if dead level.

Would I be able to set individual height? I just tried by setting both of rear corner the same height, but it didn't compensate. I also tried setting the real values (left one higher) and that did not compensate either.

Any ideas? If I can raise the rear right a bit via VAG-COM?

Thanks,

Yes. Evenly distribute them. Always works for me.

Where are these sensors / levers located? Can they be seen from lifting the car looking at them from unerneath? I jacked up the car today and compared both sides and I did not see anything out of ordinary.

Thanks,
