| Engine Head Gasket Leaking problems |
Cam cover oil leaks discovered after 50,000 mile service at approx 48,500 miles 11/7/05. Audi TSB 05-03, Nov. 2, 2005 covering 2000-2006 models a4, cabriolet, tt, a6, S4, allroad, a8, s8, and rs6 with engines 1. 8t, 2. 8 v6, 2. 7 v6t, and 4. 2 v8 states that if a customer complains and the area is wet with fluid residue or droplets that are not coming off, to clean the oil stained area and tell the customer that it could be the result of spillage when topping off or normal gasket "sweating" and is not indication of a malfunction. If found and no customer complaint, no action is to be taken. If found and only if a customer complains, then replace gaskets and leak test the engine. This is an unacceptable policy of hiding by lack of disclosure, the leak and unfairly shifting the cost of a manufacturing or design defect to the customer. Audi needs to be held accountable and forced to cover these leaks for an extended period of time and notify owners to bring their cars in for inspection and repair.
