2007 Audi A6 2.0L Diesel · GF57 YKP

The 2007 Audi A6 shows a pattern of accelerating mechanical wear consistent with its age. In the most recent test on 5 September 2025 at 134,749 miles, the vehicle passed after an initial failure involving multiple electrical and fluid issues. While the car passed, the tester identified significant corrosion on the rear sub-frame, though not yet structurally compromised, alongside worn bushes on both upper suspension arms and a corroded front coil spring. The presence of fluctuating service brakes across all four wheels suggests thinned discs or sticking calipers, which likely requires a comprehensive inspection of the entire braking system to ensure consistent stopping performance. The vehicle has covered 134,749 miles over 19 years, averaging approximately 7,100 miles per year. This low annual mileage suggests light use, but the MOT history indicates neglect of consumable rubber and metal components. In the February 2024 test at 132,069 miles, both front tyres were at or near the legal limit, with the nearside tyre measuring just 1.6mm. The recurring issue of the upper suspension arm bushes appearing in 2023, 2024, and 2025 shows a long-term degradation of the front geometry that has not been proactively addressed through replacement. Maintenance habits appear reactive rather than preventative. The September 2025 failure was caused by a non-functional washer, a defective position lamp, and incorrect headlamp aim, which were rectified to achieve the pass. However, the noted non-excessive engine oil leak and persistent fluctuating brakes are common signs of age-related Audi wear that will require monitoring to prevent more costly failure. A buyer should prioritize checking the integrity of the rear sub-frame for further rust and verifying the suspension condition, as these represent the most significant structural and mechanical risks identified in the record.
