Engine oil leaks are common from the valve cover gaskets and camshaft chain tensioner gasket.

Check Engine Light Due to Faulty Torque Converter

2004 Audi A6 Quattro Reviews

Some plastic fittings on the front passenger seat have failed. Several painted surfaces on the headlight switch, mirror switch and heating and A/C controls have worn off. The radio on/off button has come off. The front suspension needs relatively frequent repairs. The roads are terrible around here. Water pump and oil cooler replace at different times. The latter repair VERY expensive.
i love my a6
