Purchased above vehicle (new) in Sept. 2011. Serviced by Audi. Just developed noise when driving so had a mechanic friend have a look at it and he believes it is either a problem with a bearing in the gearbox or differential bearing. Warranty expired SEPT. 2014!
Anyone had similar experience?
Next week I will take it to the dealer. In view of low mileage and the service history with the dealer am I likely to get a fair deal from Audi? Many tks.
