Hi new here. thought i'd just post a problem i have. My car is an 2002 A4 1.8T quattro sport. If i am travelling at say 50mph in 5th gear and i floor the throttle,when i get between 60 and 70 mph i get a rumble noise through the car.Then when i get over 70mph it stops.Also when i pull away on a right or lefthand lock i get a rumble too.My audi dealer said it was the bearing in the propshaft.So i had it reconditioned but the problem is still there. Then i was told by another audi dealer that all quattros make the noise on a lock when pulling away when they get older.Mine has done 77000 miles.Can anyone help please?
