Driving westbound on i20 from columbia, SC to st robert/fort leonard wood, mo when engine suddenly lost power. Limped about 3/4 mi to next exit and called for a tow truck. Transported vehicle back to nearest Audi dealer (45 mi east) in columbia, SC. Audi of columbia did diagnostic and after $2527. 00 determined that the exhaust camshaft on bank 1 broke in the center. The service department manager stated he has never seen or heard of that happening in all his years with Audi. I believe that this is a material defect and I should not be charged for the replacement of the engine (service managers recommendation).
Audi A6 quattp with twin turbo, oil pump failure due to "coking" from turbos. Exact same problem as the recall on the 1. 8 turbo engine. I feel that my engine should be included even though it is a 2. 7 litre engine.
