Any thoughts on this one please? The car is a 2000 model S8 (80k miles) and
it has a rumble from the front end. It's quite bearable at cruising speed
but very noticeable at low speeds on good surfaces, where it appears as a
"wop, wop" noise each wheel revolution. Front discs and pads are new, so I
don't think it's a warped disc. Tyre wear is slightly uneven (more wear on
the outside of the tyre on both sides) but no worse than on the front tyres
of any Audi.
I suspected front wheel bearings, and last week I took it for service at a
VAG main dealer (Crewe Audi - nee Charles Audi). I told them about the noise
and said I suspected the bearings, but I told them they would need to
test-drive the car and listen to it. As soon as I'd uttered my suspicions I
regretted doing so, and guess what, they've just changed the bearings and
the noise is still there. They obviously haven't listened for the noise
either before or after doing the work.
Three questions. First, could this be worn inner or outer CV joints? Second,
could it (gulp!) be from the final drive? Third, can anyone in the UK
recommend a decent independent Audi specialist in the midlands who knows
about quattros and is actually interested in diagnosing a problem, rather
than just doing what the owner thinks might need doing? I was wondering
about BR Motorsport in Leamington. I'm in Staffordshire.
Thanks for any help.
