2009 Audi A6 2.8L Diesel · SV09 SPZ

Tyre wear and rear‑brake wear dominate the MOT record, with a near‑annual pattern of tyres flagged as “worn close to legal limit” on all corners and a recurring advisory on the nearside rear brake pads being thin. The only outright failure occurred in June 2023 when the nearside rear tyre fell below the 1.6 mm tread requirement, but the vehicle has since passed its most recent test in June 2026, albeit still carrying tyre‑wear advisories and a slightly noisy nearside rear wheel bearing. This trend suggests that while the car remains road‑worthy, consumables on the rear axle are approaching the end of their service life and should be monitored closely. At 177,153 mi spread over 17 years the average annual mileage is roughly 10,400 mi, which sits comfortably within normal usage for a vehicle of this age. The MOT history shows no prolonged gaps, indicating the car has been driven consistently rather than stored for extended periods. Steady mileage of this magnitude typically translates into progressive wear on tyres, suspension bushings, brake components and drivetrain bearings, so prospective buyers should anticipate replacement of high‑wear items and budget for a comprehensive inspection of those systems. When inspecting the car, focus first on the tyres: measure tread depth on all four wheels, look for uneven wear patterns that could betray mis‑alignment or worn suspension components, and feel for any sidewall cracks that may signal ageing. During a low‑speed drive, listen for a low‑frequency hum or grinding from the nearside rear wheel bearing, especially when the vehicle is coasting or turning; any increase in noise under load may indicate impending bearing failure. Test the rear brakes for a firm pedal feel, absence of pulsation, and listen for squeal or grinding that would confirm the thin pads and the advisory on disc condition are not yet critical but may soon require resurfacing or replacement. The MOT notes also mention a service‑warning message on the dash and the presence of fitted engine covers and undertrays, which are not defects but could mask visual inspection of the engine bay. Verify that the warning light is cleared after a diagnostic scan and that no fault codes persist. While the off‑side rear registration lamp was inoperative at the last test, it is a simple bulb replacement. Overall, the car’s roadworthiness hinges on addressing the tyre set, confirming rear‑brake performance, and checking the rear wheel bearing for developing noise before committing to purchase.
