2020 Audi A3 S Line 35 Tfsi Mhev S-A 1.5L Petrol · LX20 RGY

The most recent MOT on 29 August 2026 was passed with no recorded defects, indicating that the vehicle currently meets the statutory safety and emissions standards. Earlier in the series, the 21 August 2023 test failed due to an off‑side front tyre tread depth below the legal minimum, while the following day’s test passed but retained several advisories concerning brake pad wear and tyre condition. Since that incident the subsequent three annual tests (2024, 2025 and 2026) have been clean, suggesting that the owner has addressed the critical issues and that the overall maintenance trajectory is now stabilising and improving. At 43 232 miles the car has averaged just over 7 200 miles per year over its six‑year life, which sits comfortably within the typical UK usage pattern for a compact executive model. There are no obvious periods of unusually high mileage accumulation that would point to severe wear on high‑stress components, nor are there gaps that would imply prolonged storage beyond normal seasonal use. Consequently, the wear on drivetrain, suspension and engine internals is likely to be moderate, but the relatively low annual mileage does raise the possibility of age‑related degradation such as tyre perishing or battery electrolyte loss if the vehicle has spent extended periods idle. The advisory items from the 2023 MOT still merit attention. The front brake pads were flagged as thin; although they have not yet caused a failure, further wear could lead to reduced braking efficiency, pedal pulsation or a squealing noise under moderate braking. It is advisable to have the pads measured and, if they are within a few millimetres of the minimum thickness, to replace them together with a visual inspection of the front brake discs for scoring or rust that could cause shudder. The front tyre on the off‑side was deemed dangerous at the time of failure and should have been replaced; verify that a new tyre is now fitted and that the remaining front tyre shows even tread wear, no sidewall cracking and no edge cuts, as uneven wear can indicate mis‑alignment or worn suspension bushes. The near‑side rear tyre was noted as perishing; perished sidewalls can lead to sudden deflation, so inspect the tyre for dry rot, especially around the shoulders, and replace it if any brittleness or cracking is evident. While the vehicle passed the later tests, a comprehensive wheel‑alignment check and a visual examination of the rear suspension links, bushings and anti‑roll bar mounts are prudent to prevent future tyre wear anomalies. Beyond the tyre and brake considerations, the car’s age warrants a series of calendar‑based inspections. The 12‑volt battery, now six years old, should be load‑tested to confirm it can sustain a full charge, particularly if the vehicle has experienced periods of inactivity. Engine oil, coolant and brake fluid typically require replacement at twelve‑month intervals regardless of mileage, so confirm that the most recent service stamps reflect these changes; old brake fluid can become hygroscopic and reduce braking performance. Examine the under‑carriage for corrosion on the chassis rails, exhaust hangers and suspension mounting points, as standing water can accelerate rust on steel components. Finally, verify that any Audi‑specific recalls for the 2020 A3 S‑Line MHEV have been completed, and during a test drive listen for any clunking from the front strut assembly, monitor for steering pull, and watch for any smoke or unusual odors from the exhaust, all of which would indicate hidden mechanical issues that should be rectified before purchase.
