Parts for the Audi A4 TFSI

Known issues

Common issues with the A4 B7 in NZ include:
• Oil Consumption: Particularly prevalent in the 2.0T FSI engines due to piston ring design flaws. Regular oil level checks are paramount.
• Timing Belt/Chain Issues: Depending on the engine, timing belt replacement is critical (usually every 90,000-120,000km). Timing chain tensioner failures are common on some models, leading to significant engine damage if not addressed.
• Suspension Wear: Control arm bushings and ball joints are prone to wear, resulting in knocking sounds and imprecise handling.
• Electrical Problems: Window regulators, central locking systems, and ECU glitches are occasionally reported.
• DSG Transmission Issues (where applicable): If equipped with the DSG transmission, ensure it has been serviced according to schedule to prevent mechatronic unit failures.
