2022 Audi S4 Black ED TDI Mhev Quattro A 3.0L Diesel · SM22 VRM

The latest DVSA MOT test for the 2022 Audi S4 TDI MHEV conducted on 2026-09-01 resulted in a passing outcome, indicating that the vehicle met all current roadworthiness standards at that time. However, the MOT history reveals a concerning pattern of failure and advisories, particularly in the rear tyre and registration plate components. The vehicle failed in March 2025 due to a dangerous defect in the near-side rear tyre showing structural separation and a deep cut, which is critical as it poses a risk of sudden failure under load. While the most recent MOT passed without such failures, the prior incident suggests a potential underlying issue with tyre integrity that warrants careful consideration. The presence of an advisory regarding the rear registration plate deterioration, though not dangerous, indicates ongoing wear that could compromise visibility or regulatory compliance if not addressed promptly. The recorded mileage of 70,236 miles for a vehicle aged four years represents a high annual usage rate of approximately 17,559 miles per annum, which is notably elevated for its class and age. Such mileage accumulation typically accelerates wear on consumables like brake pads, suspension components, and drivetrain elements, as well as fluid degradation over time. The absence of significant mileage gaps suggests the vehicle has been in active use, potentially under demanding conditions that could accelerate wear on suspension bushes, coil springs, and exhaust components. Additionally, prolonged exposure to high mileage without regular servicing may lead to subtle but critical issues such as oil dilution in the diesel engine, reduced lubrication effectiveness in moving parts, or early signs of exhaust manifold corrosion if not properly maintained. As a prospective buyer, the most urgent concern is the prior MOT failure related to the near-side rear tyre, which exhibited structural failure. On inspection, you should verify the condition of all tyres, particularly for signs of bulging, cracking, or uneven wear patterns that could indicate underlying structural weaknesses. During a test drive, listen for unusual noises from the rear axle or suspension, as these may signal worn or damaged components contributing to tyre stress. The registration plate advisory suggests the rear plate may be prone to chipping or fading, so check for any visible damage that could affect readability or regulatory compliance. Beyond these immediate concerns, given the vehicle’s high mileage, prioritise a thorough inspection of the suspension system, including bushings, struts, and shock absorbers, for signs of excessive play or clunking noises, which can degrade ride quality and handling over time. Given the vehicle’s age and mileage, it is advisable to conduct a comprehensive mechanical inspection before purchase. Focus on the brake system, as high mileage often leads to reduced pad thickness, warped discs, or binding calipers, which can cause shuddering or pulsations during braking. Check the engine oil level and condition, ensuring it is clean and at the correct viscosity, as oil dilution from frequent cold starts or high mileage can accelerate wear. Inspect the exhaust system for signs of corrosion or leaks, particularly around the catalytic converter and manifold, as these areas are prone to rust in a diesel vehicle. Additionally, verify the battery’s health, as high mileage can lead to reduced cranking power or internal corrosion, which may require replacement within the next 12 to 24 months. Lastly, examine the tyre tread depth and sidewall condition for signs of perishing or cracking, which can compromise safety and warrant replacement if the tread is below the legal minimum of 1.6mm. If possible, obtain a service history to confirm adherence to manufacturer-recommended maintenance intervals, especially for fluid changes and filter replacements.
