Hello everyone! Got a 2005 A3 2.0 TDI SLine Quattro..I have a slight knock on the front wheels at low speed when turning left or right. Almost like a stick (which there isn't!) is running round the back of the wheel spoke! Only a couple of seconds but it's there! I know for sure one bearing has been replaced not sure about the other. Never had Audi before so I'm a bit dumb! Thanks!
