Parts for the Audi A6 BBJ Wagon 160kW (2005-2006)

Known issues

Common problems with the 2005-2006 Audi A6 include issues with the MultiTronic CVT transmission (on front-wheel drive models), oil leaks (especially from the valve cover gaskets and timing chain tensioners), and electrical gremlins affecting sensors, lights, and the infotainment system. Carbon buildup can be a problem on direct-injection petrol engines, leading to reduced performance and fuel economy. Suspension bushes and control arms can also wear out, resulting in knocking noises and uneven tyre wear. Diesel models may experience DPF (Diesel Particulate Filter) issues if not driven regularly on longer journeys.

WOF tips

When taking your 2005-2006 Audi A6 for a WOF, pay close attention to the following: Check for excessive oil leaks, as they will often result in a failure. Ensure all lights are functioning correctly, including headlights, taillights, brake lights, and indicators. Suspension components will be thoroughly inspected for wear and tear. Brake pads and rotors must be within acceptable limits. Tyre condition and tread depth are also critical. A malfunctioning parking brake is another common failure point. Because of the age of these, rust must be minimal, focusing on the undercarriage.

About the Audi A6 BBJ Wagon 160kW (2005-2006)

The C6 generation A6 comes with an array of engine options, from fuel-efficient petrol and diesel engines to robust V6 and V8 powerhouses. Audi’s Quattro all-wheel-drive system enhances handling for a secure grip on New Zealand's varied terrain. Inside, the A6 treats occupants to a comfortable, well-furnished cabin, though it’s worth noting that the advanced electronics may sometimes present challenges. As many of these models have miles under their belts, consistent maintenance is vital.

Suspension components also bear watching as they endure New Zealand’s unique road conditions; regular inspection can save on costly repairs later. The brakes—pads and rotors—should be serviced routinely to maintain both safety and performance, making our Braking service pack a great option. Additionally, replacement of air filters and spark plugs ensures your engine runs smoothly, contributing to overall reliability. Lastly, with the common challenge of oil leaks, particularly from the valve cover gaskets, timely intervention is essential to prevent further issues down the line. Utilizing our extensive Filtration category keeps your car running like new.
