The Audi A6 C5, produced between 2000 and 2005, is a cherished choice among Kiwi car enthusiasts. This generation blends luxurious design, spirited performance, and everyday practicality. Whether you're drawn to the economical TDI, the elegant V6, or the exhilarating 2.7T, the C5 A6 caters to a variety of tastes. However, owning a vehicle of this age does come with its quirks. Let's explore the key aspects to consider when owning this classic Audi.
Common issues on the C5 A6 include coil pack failures (especially in the turbo models), vacuum leaks (leading to poor performance and fuel economy), suspension wear (control arm bushings are a known weak point), and automatic transmission problems (especially with age and lack of maintenance). On TDI models, check for turbocharger issues and blocked EGR valves. The 2.7T is notorious for its complexity making maintenance more costly and more frequent.
WOF tips
When getting a WOF, pay close attention to suspension components (check for play in ball joints and bushings), brake lines (corrosion is common), and headlight alignment (the self-leveling system can fail). Also check for excessive oil leaks, as these are a WOF failure point. Rust is less of a concern on these Audis than some other makes, but still inspect around the windscreen, sills, and wheel arches.
About the Audi A6 TDI
The C5 A6 is available in both sedan and wagon configurations ('Avant'), boasting a range of engine options from the efficient 1.8L Turbo I4 to the more robust 4.2L V8. The Quattro all-wheel drive system is a highlight, ensuring excellent traction regardless of the conditions encountered across New Zealand's diverse climates.
However, potential owners should be aware of common issues that may arise. For instance, the cooling system components, including the water pump and thermostat, are recommended for inspection around the 150,000 km mark. Addressing these early can prevent expensive repairs, and you can find all necessary parts in the Cooling category. Additionally, regular brake pad replacements are crucial for safety, and we offer comprehensive brake service options, including both front and rear brake maintenance—essential for ensuring the integrity of your stopping power. If you’re considering an oil change, it’s a simple task that can be performed every 10,000 km and is vital for engine longevity, linking to our Oil Service category. Remember, routine inspections and maintenance, including air and oil filter changes, will keep your A6 running smoothly and efficiently.
