guys i just bought a new rs3. when the car is worm these is a rattle on the exhaust like a shield is touching the exhaust slightly its very loud and everyone has pointed it out to me. you can even hear it when i have the car ticking over on the drive and iam in the house. sounds like a banger lol. its mainly when its ticking over and pulling away. doesn't always happen though audi said they cant find anything wrong so must be normal bull sh*t! but i have found the problem myself there is a valve type thing on the back box in between the tails. its coming from that its like it needs tightning up or its missing summit not sure. also when i bough the car new the steering wheel wasn't dead centre when driving straight like it was at 11.50 instead on 12 o clock. told them to sort that and its still not straight! its now at 11.55. useless!.
