Got the A6 serviced today and asked them to check a droning noise coming from the front, thinking maybe wheel bearings.
they tell me that the differential bearing in the gearbox is gone and a new box is the way to go!!!
i have no experience when it comes to gearboxes and wondering if anyone on here has a better idea.
the car is a 2003 A6 2.5tdi sport with a 6 speed manual box
