The Audi A6 C4, produced from 1994 to 1997, is a distinguished executive sedan that exemplifies Audi's refinement and reliability. With its roots in the Audi 100, the A6 introduced innovative updates while maintaining a timeless appeal. Available new or as imported used models in New Zealand, these vehicles are now becoming vintage treasures that need regular care to preserve their legacy.
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.
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.
The A6 C4 is powered by a selection of inline-four and V6 petrol and diesel engines, complemented by either front-wheel drive or Audi's celebrated Quattro system. This combination not only provides a smooth, composed driving experience but also makes this vehicle ideal for everyday commuting or long-distance travel. However, as these cars age, certain parts may require attention. Common replacements include essential components like water pumps, alternators, and brake pads. Regular servicing, including an oil change, is advisable approximately every 10,000 km to ensure optimal engine performance.
It's important to be aware of the potential issues that may arise, such as common oil leaks or wearing suspension bushes. These can lead to knocking noises or less responsive handling. Inspections of the suspension components and cooling system are vital; for example, you should check the water pump, thermostat, and radiator hoses around the 150,000 km mark to prevent overheating.
