2020 Audi A4 Allroad Sport 40TDI Quat SA 2.0L Diesel · SW20 NBL

The most recent MOT, carried out on 2 February 2026, was passed with no recorded defects, indicating that the vehicle met the statutory safety and emissions standards at that time. Over the six‑year MOT record the pattern shows two isolated failures – a tyre‑tread deficiency in early 2024 and an engine‑MIL/SRS warning in early 2025 – each of which was rectified before the following test, after which the car has recorded consecutive passes. This suggests a maintenance response that has stabilised the vehicle’s condition, with the recent trend pointing towards steady compliance rather than a deteriorating state. At 42 641 miles the car averages roughly 7 100 miles per annum, a usage rate that sits comfortably within the typical range for a 2020 model. The mileage does not indicate any periods of excessive short‑term mileage accumulation that would accelerate wear on high‑stress components such as the clutch, gearbox or suspension. Conversely, the relatively modest annual distance means that consumables are likely to be closer to calendar‑based wear rather than purely mileage‑based, so age‑related degradation should be considered alongside the odometer reading. Although the current MOT is clean, the earlier tyre‑tread failure warrants a thorough visual and tactile inspection of all four tyres. Verify that the tread depth exceeds the legal 1.6 mm minimum and look for sidewall cracking, dry rot or uneven wear patterns that could betray mis‑alignment, worn suspension bushes or failing coil springs. During a test drive listen for any clunk or knock from the rear suspension when negotiating bumps, and feel for any pull to one side which might indicate a need for an alignment or tyre‑rotation service. Given the 2025 engine‑MIL and supplementary restraint system warning, a full electronic diagnostic scan is advisable to confirm that the fault codes have been cleared and that no latent issues remain; watch for a persistent check‑engine light, rough idle, loss of torque or any airbag warning lamp illumination, all of which would suggest that the electronic control unit or related sensors have not been fully remedied. Because the car is now six years old, time‑based components should be examined regardless of mileage. The 12‑volt lead‑acid battery may be approaching the end of its service life and should be load‑tested; a weak battery can cause intermittent electronic faults. Inspect the brake discs and pads for surface rust, glazing or uneven wear, especially if the vehicle has spent long periods stationary, and verify that the calipers move freely without binding. Check the condition of the coolant, engine oil and transmission fluid – many manufacturers recommend fluid changes at fixed intervals (often every 30 000 miles or two years) even if the vehicle appears well maintained. Finally, ensure that the service book contains regular stamps for oil changes, filter replacements and any major service work, as a complete service history is a strong indicator that the car has been looked after and will give the buyer confidence in its ongoing roadworthiness.
