The 2002-2004 Audi A4 (B6) is a beloved compact executive car that combines elegant aesthetics with exhilarating performance and everyday practicality. This model marked a significant step forward in quality and refinement compared to earlier iterations, proving to be a popular choice among New Zealand drivers. With its well-appointed interior and a choice of reliable engine options, the A4 sets a high standard for compact cars, while potential buyers should be attentive to the common issues that can arise as this vehicle ages.
Common issues on the 2002-2004 Audi A4 (B6) include: Timing belt failure (crucial – check service history!). Oil leaks: Valve cover gaskets, cam seals, and turbocharger oil lines (on turbocharged models) are all potential sources. Suspension issues: Control arm bushings wear out quickly, leading to clunking noises and poor handling. Cooling system problems: Leaks in the radiator, hoses, and water pump are common. Electrical issues: Window regulators, door locks, and central locking systems can fail.
When inspecting an Audi A4 (B6) for a WOF in New Zealand, pay close attention to: Suspension: Worn control arm bushings, ball joints, and shock absorbers are common failures. Brakes: Check brake pad thickness, rotor condition, and ensure the parking brake functions correctly. Lights: Ensure all lights are working and properly aligned. Tyres: Check tread depth and condition. CV Boots: Check for splits and grease leaking. Fluid leaks: Oil and coolant leaks are easily spotted and will cause a failure.
The B6 generation A4 excels in delivering a comfortable and smooth driving experience, captivating its drivers with its stylish interior and array of engine choices. While front-wheel drive and Quattro all-wheel drive models cater to different preferences, attention must be paid to maintenance over time. Common parts like control arm bushings may need replacement to counteract wear, and the suspension system should be checked to maintain handling quality. Additionally, regular intervals for servicing, such as an oil change, spark plug replacement, and brake pad replacement, are recommended to keep everything running smoothly.
The electronics in the A4 often require a cautious approach, as window regulators and door lock systems can fail, signaling the need for inspection. Owners should not overlook the cooling system, which requires careful monitoring and should ideally be addressed around 150,000km—particularly looking out for the water pump, thermostat, and radiator to prevent any costly repairs.
