The Audi A6 (C5 generation) from 1997-2004 is a hallmark of Audi's pursuit of luxury, performance, and technological sophistication. As one of the standout models from the early 2000s, it exemplified Audi's vision of blending style with practicality. However, with age comes the need for due diligence. If you're thinking about acquiring a used A6 in New Zealand, let's explore the key aspects you need to consider to ensure you're making a sound investment.
Common issues on the 1997-2004 Audi A6 include: failing mass airflow (MAF) sensors, particularly on petrol models; oil leaks from valve cover gaskets, rear main seal and other common areas; suspension wear, specifically the control arms and bushings that are prone to failure, leading to knocking noises and poor handling; and electrical gremlins, such as faulty window regulators, central locking issues, and instrument cluster problems. Turbocharger issues (if equipped) are also something to be mindful of. ABS module failures can also occur.
WOF tips
When inspecting a 1997-2004 Audi A6 for a WOF, pay close attention to: suspension components (especially control arm bushings) for excessive play; brake lines and hoses for corrosion and leaks; headlight alignment (often affected by suspension wear); tyre condition; and exhaust system integrity. Rust, while less prevalent than on some older makes, can still be an issue, especially in areas prone to salt spray. Ensure all ABS and dash warning lights are operating correctly.
