The Audi A6 (C6 generation, 2008-2011) stands as an iconic representation of Audi's commitment to luxury and performance. With its sleek lines and spacious, well-appointed interior, it delivers an experience that resonates with those who appreciate fine engineering. As these models enter the used market at attractive prices, prospective buyers should remain mindful of common issues that could impact ownership experience. Let’s explore what makes the A6 special, alongside essential maintenance insights to keep your journey smooth and enjoyable.
• Timing Chain Tensioner (2.0T): A known weak point, especially on early models. Listen for rattling on startup. Failure can be catastrophic.
• Oil Leaks: Valve cover gaskets, timing cover, and rear main seals are prone to leaking as the car ages. Regular checks are crucial.
• DSG Transmission (S-Tronic): Requires regular servicing (oil change) at the specified intervals (typically every 60,000km) to prevent issues like jerky shifting or premature wear.
• Suspension Airbags (where fitted): Can develop leaks, leading to a sagging vehicle or compressor failure.
• Electrical Gremlins: Audis of this era can be prone to minor electrical issues, from sensor malfunctions to infotainment glitches.
• Lights: Ensure all lights (headlights, taillights, brake lights, indicators) are functioning correctly. Check for proper alignment of headlights.
• Brakes: Ensure discs and pads have adequate thickness. ABS and ESP systems should be functioning, or a warning light will trigger a failure.
• Suspension: Check for worn ball joints, bushings, and shock absorbers, especially if the car has air suspension. Any play in the suspension components is a fail.
• Tyres: Ensure tyres meet minimum tread depth requirements (1.5mm) and are in good condition (no sidewall damage or perishing). Matching tyres on each axle is recommended, especially for Quattro models.
• Fluid Leaks: Excessive oil or coolant leaks will result in a WOF failure.
The C6 A6 promises a comfortable ride with a selection of efficient diesel engines and robust V6 petrol options. Its Quattro all-wheel drive enhances stability, especially on New Zealand's winding roads. However, as with any sophisticated vehicle, regular maintenance is crucial to ensure long-term satisfaction. For instance, the cooling system should be monitored around the 150,000km mark, prompting checks on the water pump, thermostat, and radiator hoses.

Regular servicing, which includes oil changes every 60,000km, will help mitigate these concerns. Don’t forget about the brake system; a front or rear brake service is essential to keep your driving experience safe and enjoyable.
