2017 Audi A6 3.0L Diesel · HG17 ABO

The 2017 Audi A6 has demonstrated a stable roadworthiness trend over its MOT history, with the most recent test on 2026-02-24 at 136,001 miles resulting in a clean pass—no defects or advisories recorded. This consistency suggests that, at least in terms of MOT compliance, the vehicle has not experienced recurring or critical failures. The absence of advisories in any test implies that no major components were deemed borderline or requiring imminent attention at the time of inspection. However, the 2025-03-04 failure at 130,300 miles—just one mile before passing the next day—stands out as an anomaly, though no defects were logged, which may indicate a minor administrative oversight rather than a mechanical issue. The mileage progression reveals a high annual average of approximately 15,111 miles, which is above typical expectations for a nine-year-old vehicle. Between 2023-03-02 (116,993 miles) and 2024-02-28 (121,481 miles), the car accumulated 4,488 miles in just over a year, while the gap between 2024-02-28 and 2025-03-05 (9,824 miles) suggests a period of more intensive use. The final stretch from 2025-03-05 to 2026-02-24 (5,701 miles) indicates sustained driving, which could accelerate wear on suspension bushes, coil springs, and brake components. The lack of advisories in any test does not preclude underlying issues, particularly given the elevated mileage. Given the absence of recorded faults, a buyer should prioritise a thorough inspection of high-wear areas that are not routinely captured in MOT tests. The suspension—particularly the rear coil springs and bushes—should be checked for uneven sagging or excessive play, as high mileage often accelerates degradation in these components. Binding brake calipers or unevenly worn brake discs, which could go unnoticed without dynamic testing, warrant attention, especially if the vehicle exhibits pulling or reduced braking efficiency. Corrosion at wheel arches, subframes, and exhaust mounts should also be examined, as prolonged exposure and high mileage increase the risk of structural compromise. Finally, the exhaust system’s integrity should be verified, as catalytic converter or muffler failures are common in high-mileage vehicles and often result in advisory notes or failures if emissions exceed limits.
