2017 Audi A4 2.0L Diesel · YL66 FEF

The 2017 Audi A4 has maintained a clean MOT history across five consecutive tests, with no defects or advisories recorded in any of the most recent examinations. The February 2026 pass at 111,582 miles confirms the vehicle remains roadworthy under current DVSA standards, though the absence of advisories does not preclude underlying issues requiring closer inspection. The consistent pass status suggests either diligent servicing or deferred maintenance—though the latter carries higher risk given the vehicle’s age and mileage. Buyers should note that no advisory notes imply potential problems were overlooked, but the lack of recorded faults does not guarantee all components are in optimal condition. The mileage progression reveals an unusually aggressive usage pattern for a nine-year-old vehicle. Between March 2022 (61,455 miles) and February 2026 (111,582 miles), the car accumulated 50,127 miles in just under four years, averaging over 12,000 miles annually—a rate that exceeds typical expectations for this model. The gap between the 2023 (76,957 miles) and 2022 (61,455 miles) tests, where mileage jumped by 15,502 miles in just over two months, further suggests inconsistent or heavy usage. Such rapid accumulation increases wear on suspension bushes, coil springs, and drivetrain components, while also raising concerns about brake pad life and tyre degradation. Given the high mileage and inconsistent usage, a buyer should prioritise an independent inspection of suspension integrity, particularly the rear coil springs and bushes, which often degrade prematurely under heavy loads. The braking system warrants scrutiny—binding calipers or uneven wear on discs could have gone unrecorded if not severe enough to fail an MOT. Corrosion at wheel arches, subframes, and exhaust mounts should be checked, as prolonged standing periods may have accelerated rust formation despite the clean MOT record. Finally, the exhaust emissions system, while not flagged, should be tested for leaks or catalytic converter efficiency, as these can deteriorate without obvious external signs. The absence of advisories does not rule out hidden wear; thorough mechanical checks are essential.
