The Audi A4 (B7 generation, 2004-2008) is a defining vehicle in Audi's legacy, seamlessly blending sleek style with impressive performance. Renowned for its balance between luxury and reliability, the B7 A4 has captured the hearts of many Kiwis, with its presence still felt on our roads today. Owning one of these cars means investing in a cherished piece of automotive history that requires dedicated care and maintenance to keep it running smoothly and looking its best.
Common issues with the B7 A4 include oil leaks (especially from the valve cover gasket), coolant leaks (plastic coolant flanges are prone to cracking), turbocharger problems (on turbocharged models), suspension wear (control arm bushings and ball joints), and electrical glitches (window regulators, central locking). The Multitronic CVT gearbox (available on some models) can be problematic and expensive to repair. Carbon buildup on the valves is common in direct-injection engines (2.0T), leading to reduced performance. Check for timing belt service history (if applicable) as failure can cause catastrophic engine damage.
