This generation of the A4 not only upheld Audi's illustrious tradition of sophistication and engineering excellence but also provided an enjoyable driving experience that many New Zealanders have come to love.

Parts for the Audi A4 TDI

Known issues

Common faults for this A4 included: Oil leaks (valve cover gaskets, cam chain tensioner seals), coolant leaks (water pump, thermostat housing), suspension wear (control arm bushings, ball joints) and failing coil packs. Oil consumption issues can also be present, especially in the 2.0T models. The Multitronic CVT gearbox can be prone to issues. Check if car idles unevenly. Check that all electric accessories work. Make sure the air conditioning works and that it blows cold as the AC compressors are common to fail on these vehicles.

WOF tips

For WOF inspections: Worn suspension components (bushings and ball joints), tyre condition (uneven wear), and brake wear are critical. Make sure to check the CV boots for any tears. Evidence of fluid leaks (oil or coolant) can also lead to WOF failure. Also, ensure all lights are functioning correctly. The parking brake may also cause issues in tests.

About the Audi A4 TDI

The Audi A4 (2006-2009) was offered with various engine options, including robust petrol and fuel-efficient diesel variants. The turbocharged engines, particularly the 1.8T and 2.0T, deliver the perfect mix of power and economy, ensuring every drive is enjoyable. Inside, expect a premium ambiance crafted from high-quality materials, paired with a comfort that transforms any journey.

However, as these beloved vehicles age, keeping an eye on regular maintenance is crucial. Recommended service intervals for engine oil changes, spark plug replacements, and brake pad servicing will help maximize performance. Common faults can include oil and coolant leaks—particularly from the water pump and thermostat—and suspension wear that necessitates timely inspections of control arm bushings and ball joints. For instance, around 150,000 km, the cooling system should be thoroughly examined, focusing on the water pump, thermostat, and radiator hoses to prevent overheating issues.
