The Audi A6 C4, a masterpiece of automotive history produced from 1994 to 1997, represents a perfect blend of refinement and performance. With its iconic transition from the Audi 100 to the A6 nameplate, the A6 C4 delivers a superb combination of edgy design, exceptional comfort, and unrivaled durability. This model has garnered loyalty among New Zealand drivers, establishing itself as a classic. It’s a vehicle that speaks to the heart of its owners, offering both a reliable daily driving experience and a distinguished presence on the road.
Owners often report issues with the automatic transmissions which may exhibit harsh shifting or slipping. Oil leaks are also common, particularly from the valve cover gaskets and crankshaft seals. The cooling system, including the radiator and water pump, is also prone to failures due to age. Electrical issues, especially with the central locking system, are also frequently reported. Suspension components, such as the bushings and ball joints, may need replacing due to wear and tear.
WOF tips
Pay close attention to rust, particularly around the wheel arches, sills, and underbody. Suspension components such as ball joints and bushes are routinely checked, and worn parts will cause a WOF failure. Headlight alignment is crucial, as these can deteriorate over time. Also check the condition of brake lines for corrosion, as this is a very common WOF failure point. Finally, ensure all lights (headlights, taillights, brake lights, indicators) are functioning correctly.
About the Audi A6 TDI
The C4 A6 comes with an impressive array of engine options, including the fuel-efficient TDI diesel variants that are especially sought after for their longevity and low running costs. With common maintenance intervals around 15,000km, it’s crucial to keep an eye on wear-and-tear parts like the water pump, radiator, and thermostat, particularly as the vehicle approaches 150,000km. Owners may experience issues with the automatic transmission, often resolved with timely servicing. Addressing oil leaks from the valve cover gaskets and crankshaft seals as they arise can significantly prevent more extensive repairs down the line. The A6’s braking system also demands regular checks — pads and rotors should be inspected at every service to maintain safety and performance.
