2017 Audi A6 S Line TDI Quattro S-A 3.0L Diesel · FP67 BYK

The vehicle’s most recent MOT test on 2025-05-20 at 79,083 miles confirms it remains roadworthy without any recorded defects, suggesting a stable maintenance trend over the past three tests. The absence of advisories or failings across all three MOTs—including the 2023 and 2022 tests at 59,163 and 48,011 miles respectively—indicates no recurring mechanical issues have been formally documented. However, the gap between the 2023 and 2025 tests (21 months) is unusually long, exceeding the standard 12-month interval. While this does not inherently signal neglect, it raises a question about whether intermediate checks may have been overlooked, particularly for components like suspension bushes, coil springs, or brake caliper binding, which are not routinely covered by the MOT but can degrade between tests. The mileage progression of roughly 8,787 miles annually—consistent between 48,011 and 59,163 miles (2022–2023) and 59,163 to 79,083 miles (2023–2025)—suggests typical usage without extreme wear patterns. There are no red flags in the recorded mileage, though the extended period between tests could imply either infrequent driving or a lack of pre-MOT servicing. The absence of advisories in any test further supports that no major components were failing at the time of inspection, but this does not preclude gradual wear in areas like exhaust systems, underbody corrosion, or turbocharger efficiency, which are not always caught by the MOT. Given the clean MOT history, a buyer should prioritise a thorough inspection of high-wear items not covered by the test, such as the suspension’s rubber bushes and coil springs for cracking or excessive play, particularly at the rear where TDI vehicles often develop binding issues. The turbocharger and intercooler should be checked for oil leaks or carbon buildup, as TDI engines are prone to soot-related wear. Underbody corrosion, especially around the sills and wheel arches, should be examined for structural integrity, as this model is susceptible to rust progression over nine years. Finally, the brake discs and pads—while not failed in MOTs—should be assessed for uneven wear or glazing, as binding calipers or warped rotors can develop between tests. The lack of documented faults does not guarantee these areas are flawless, so visual and functional checks are essential.
