Parts for the Audi A4 TFSI

Known issues

Common issues include oil leaks (especially from the valve cover gasket and cam chain tensioner), coil pack failures (particularly on the 2.0T engine), and worn suspension components. Carbon buildup can also be a problem on direct-injection petrol engines. Diesel models can suffer from diesel particulate filter (DPF) blockages if not driven regularly on longer journeys. Check for error codes using an OBD2 scanner.

WOF tips

WOF failures often relate to worn suspension components (especially ball joints and bushes), brake condition (pads, rotors, and hoses), and headlight alignment. Oil leaks are a common cause for concern. Make sure the exhaust system is in good condition and free from excessive rust. The airbags and seatbelts must be functioning correctly, with no warning lights illuminated. Also, check all lights are functioning correctly.
