2015 Audi A4 2.0L Diesel · ST15 RYG

The most recent MOT test for this 2015 Audi A4 was conducted on 2025-09-25 and passed without any recorded defects, marking a positive turnaround following a failed inspection in 2021. While the vehicle has demonstrated consistent MOT compliance since 2020, the advisory history over the past five years—particularly the recurring wear-related advisories on brake discs, tyres, and suspension components—suggests a pattern of gradual mechanical degradation rather than a sudden deterioration. The absence of major failures since 2021 indicates that maintenance has likely been addressed promptly, but the advisories highlight areas requiring ongoing attention to prevent progression into more severe issues. The overall maintenance trend appears stable, with no evidence of neglect, but vigilance is warranted to mitigate wear progression, especially given the vehicle’s age and accumulated mileage. The vehicle’s recorded mileage of 73,867 miles at this point represents a moderate annual usage rate of approximately 6,715 miles per year, which is within the expected range for a 11-year-old car. Lower mileage could imply periods of inactivity, potentially leading to issues such as standing corrosion on brake components, suspension linkages, or exhaust systems, while higher mileage would accelerate wear on consumables like tyres, brake pads, and fluids. The consistency of the mileage suggests a steady driving habit, but the advisories from previous MOTs—particularly those related to tyre edge wear and brake disc thinning—may reflect underlying wear patterns accelerated by either higher-than-average usage or less-than-optimal maintenance practices. The suspension advisories from 2023 also point to potential long-term stress on the lower control arms and bushings, which could develop into binding or excessive movement if not monitored closely. Given the recurring advisories on brake discs and tyres, the prospective buyer should prioritise a thorough inspection of the braking system, focusing on disc thickness, caliper operation, and the absence of binding or excessive heat discolouration. Listen for uneven brake pedal travel, a grinding or squealing noise during braking, or a pulsating sensation in the steering wheel, which could indicate warped discs or internal brake failure. Check for uneven tyre wear patterns, particularly on the edges, which may signal misalignment, suspension issues, or incorrect tyre pressures. The tyres should also be inspected for sidewall cracking or perishing, which can compromise structural integrity, especially in a vehicle of this age. For the suspension, feel for excessive clunking or rattling when driving over bumps, which could indicate worn suspension bushes or damaged control arms. Additionally, verify that the vehicle’s headlamps are correctly aligned and functioning, as the 2021 MOT failure highlighted a need for this adjustment. For the 2015 Audi A4 at 73,867 miles, a practical inspection should also cover the 12-volt battery for signs of corrosion or poor connections, which can develop from prolonged standing or infrequent use. Check the fluid levels in the cooling system, transmission, and differential, ensuring they are topped up and free from contamination, as fluid degradation over time—particularly in the cooling system—can lead to overheating or engine damage. Inspect the exhaust system for rust or structural weakness, especially around the catalytic converter and tailpipes, and listen for unusual noises or backpressure, which could indicate exhaust leaks or component failure. Finally, verify that the service book is up to date, as the vehicle’s age and mileage may warrant a full service or fluid refresh, including brake fluid, differential fluid, and transmission fluid, to prevent calendar-based degradation. If the vehicle has been driven at a moderate pace with minimal standing periods, the buyer should also check for tyre sidewall perishing, which can occur even with low mileage due to age-related material degradation.
