My A4 needs yet another front wheel bearing replaced. Already had one replaced under warranty at ca. 35k miles, near-side replaced about 1500miles ago and now off-side needs replacing. I did not have this problem on my three previous Audis which all covered high mileages. Much of my day-to-day mileage is on minor roads but I'm not going off-road with it! Is there a problem with Audi wheel bearings on this model? And, no, it's not the tyres.
