The Audi A6 C4, produced during the notable years of 1996 and 1997, embodies the classic blend of German engineering and practicality. This vehicle not only signifies a pivotal shift from the Audi 100 but also invites Kiwis into the realm of European luxury at an accessible price point. As a cherished entry into European motoring, this A6 stands out with its refined design and focus on driver comfort, yet requires diligent maintenance to ensure its longevity and reliability.
Common issues with the A6 C4 include oil leaks from various engine seals, cooling system problems (radiator, hoses, water pump), and electrical gremlins that affect the lighting and other systems. Suspension components, especially control arm bushings, also wear out over time. Diesel models can suffer from injection pump and turbocharger issues.
During a WOF inspection, thoroughly check the suspension for wear and play, especially in the front control arms and ball joints. Pay close attention to the brake system and ensure it is functioning effectively. Inspect for any significant oil leaks, as these will likely lead to a failure. Ensure all lights are working correctly and that the vehicle is free from excessive rust or corrosion, especially in the underbody and sills.
The A6 C4 offers a variety of engine options, including inline-4, V6, and inline-5 configurations, serving both petrol and diesel preferences. Notably, the Quattro all-wheel drive feature is available on select models, enhancing handling in diverse driving conditions. Inside, you'll find a cabin designed for functionality with a keen focus on driver comfort, making every journey enjoyable. However, due to its age, expect to conduct maintenance more frequently. Keeping an eye on components such as the water pump, brake pads, and engine filters is prudent.
It's advisable to check the cooling system components around 150,000 km — the water pump, thermostat, and radiator hoses should all be inspected to avoid overheating issues. Our service packs, including the Cooling and Filtration categories, offer the perfect parts to keep your A6 healthy. Furthermore, as braking plays a crucial role in safety, regular brake pad replacements are essential; refer to our Braking category for quality parts. Remember, minor upgrades to the suspension can significantly enhance your driving experience, ensuring this classic remains as enjoyable as the day you brought it home.
