hi, thanks for the reply, to be honest, i'm not really sure where it's coming from. the car was laid up for the best part of a year so I changed the starter, oil, filters, the works. i got a set of audi tt wheels which I put on her but the noise only seems to be happening at 40mph and then stops so i thought that ruled out the alloys although i could be wrong. it's feels like something rubbing when you're driving and the pitch stays the same if you could call it a pitch. would if have anything to do with the gear box?
