2001 Audi A4 1.8L Petrol · OU51 AGX

The most recent MOT test on 17 October 2023—just 2 years and 9 months ago—shows the vehicle failed without any recorded defects, a rare outcome that suggests either an administrative error or a test centre oversight. The preceding two tests in October 2022 and October 2021 both passed cleanly at 125,204 and 118,921 miles respectively, indicating no consistent mechanical issues were detected. While the failure itself raises suspicion, the lack of defects means no recurring faults were formally logged, leaving the roadworthiness status technically stable but unproven. Buyers should verify the failure’s cause through service records or a pre-purchase inspection, as a clean MOT history does not guarantee underlying wear. The recorded mileage of 128,689 miles over 25 years—approximately 5,148 miles annually—is unusually low for a vehicle of this age, suggesting either infrequent use or prolonged periods of storage. The gap between tests averages around 6,000 miles, which is reasonable for a well-maintained car, but the consistent annual mileage implies minimal real-world stress on components like suspension bushes, coil springs, or drivetrain seals. However, low mileage does not exempt the vehicle from age-related wear; rubber components, such as suspension mounts and brake hoses, may still require inspection, as can corrosion in underbody areas or wheel arches, which can develop even with limited movement. Given the sparse MOT record, a buyer should prioritise a thorough inspection of suspension integrity, particularly the rear axle and coil springs, as these often degrade predictably over 25 years. Binding brakes or uneven wear on brake discs, which could have been missed in a clean pass, should be checked, along with the condition of the exhaust system for leaks or corrosion. The failure in 2023—despite no defects—also warrants scrutiny of the vehicle’s identification or service history, as discrepancies in MOT records can indicate tampering or incomplete maintenance. Structural corrosion, especially around the sills, subframe, or rear trailing arms, is another critical area to assess, as it can compromise the vehicle’s handling and safety without always appearing in MOT results.
