Parts for the Audi A6 S6 4.2

Known issues

Common issues on the A6 C4 include worn suspension bushes, especially on the front control arms, leading to knocking noises and vague handling. Oil leaks from the valve cover gaskets and around the engine are another frequent concern. The automatic transmissions, while generally reliable, can suffer from torque converter issues and shift problems as they age. Electrical gremlins, such as failing window regulators and central locking malfunctions, are also worth checking.

WOF tips

When inspecting an A6 C4 for a WOF, pay close attention to the condition of the lighting system, including headlights, tail lights, and indicators. Check the brakes thoroughly, ensuring the discs and pads have sufficient thickness and that the brake lines are free from corrosion. Suspension components, particularly the ball joints and bushes, should be inspected for excessive play. Rust can be an issue, especially around the wheel arches, door sills, and underbody, so check these areas carefully.
