I'm new here so I'll pop over to the welcome section sometime soon to introduce myself properly but I am considering buying a 2001 Audi S3 210 bhp. The one I'm considering all checks out okay with a good SH and fairly tidy all over. I wouldn't say it was 'pampered' car but certainly it's been looked after and has most of it's stamps from dealers with receipts etc. I've read all the buying guides etc which have all been a great help so thanks for that.
I noticed one thing on the test drive which I haven't been able to find an answer for though. When doing around 40 - 50 mph I noticed a road-speed noise coming from the rear, like a gentle woomp woomp woomp in time with the wheel spinning. It wasn't only doing it at 40 - 50 but certainly that's where it was most noticeable. It's not a loud noise, you only really notice it if you press the clutch in and let the car free-wheel, it doesn't really sound mechanical to me and it's definitely not a whine.
It's very possible it could be a slightly out or round tire or flat-spot because the car hadn't been used for a few months. However, there was no noticeable vibration, just the noise.
I know it's hard to diagnose noises on the t'internet but I thought it was worth checking your opinions here first and whether I'm just being a bit paranoid over Haldex / 4wd issues. It's possible it's completely normal too....
Thanks in advance for the help!
