The Audi A4 B6 and early B7 generation models from 2004 to 2008 have established themselves as preferred vehicles in New Zealand, celebrated for their sophisticated design, advanced engineering, and unmatched driving comfort. With various engine options, from the sporty 1.8T to the high-performance 3.2 V6 S4, these models cater to different driving styles. For New Zealand terrain and weather conditions, the Quattro all-wheel drive system offers an added layer of capability, making every drive enjoyable, whether on winding roads or during unpredictable weather. However, potential buyers should be aware of common maintenance considerations to keep these vehicles performing at their best.
Common issues with the 2004-2008 Audi A4: Oil Consumption (2.0T): The 2.0T engine is known for oil consumption issues. Regular monitoring and using the correct oil is crucial. Timing Chain Tensioner (2.0T): The timing chain tensioner can fail, leading to serious engine damage. Listen for rattling noises on startup. Coil Packs: Coil packs are a common failure item on the 1.8T and 2.0T engines. Suspension: Front control arm bushings, especially on kiwi roads, can fail causing MOT/WOF failures. Water Leaks: Clogged sunroof drains are known to cause water leaks into the interior, especially in the footwells.
When getting a WOF for a 2004-2008 Audi A4, be mindful of: Brakes: Check brake pad thickness and rotor condition. The parking brake must function correctly. Suspension: Inspect all suspension components for excessive play or damage. Pay close attention to the condition of the control arm bushings. Tyres: Ensure tyres meet legal tread depth requirements and have no cuts or bulges. Lights: All lights must be functioning correctly, including headlights, taillights, brake lights, and indicators. Exhaust: The exhaust system must be free from leaks and securely mounted. Pay attention to rust as this is now getting old.
The 2004-2008 Audi A4 models feature an extensive range of engine options, offering a balance of performance and efficiency. Regular servicing is critical for maintaining the health of your A4 S4, especially considering common issues with the 2.0T engine, including oil consumption and a potentially failing timing chain tensioner. Owners can benefit from regular intervals for oil changes, spark plug replacements, and brake pad servicing, ensuring smooth operation and safety on Kiwi roads. Pay close attention to the cooling system, which typically requires inspection around 150,000km; this includes replacing the water pump, thermostat, and radiator hoses to avoid overheating issues. It’s also wise to keep Control Arm Bushings in check, especially given the challenging driving conditions in New Zealand.
