2014 Audi A3 2.0L Diesel · NA64 BSV

A dangerous bulge on the nearside rear tyre recorded in the April 2026 MOT places the car outside legal road‑worthiness until the tyre is replaced, and the same test also noted a front oil leak that, while not excessive, remains an unresolved advisory. Earlier MOTs show a pattern of tyre‑related concerns – a cut on the same rear tyre in 2021 and a front‑right tyre approaching the legal tread limit in 2021 – alongside intermittent electrical faults such as a failed nearside front headlamp in 2024. The overall trend is one of recurring tyre and minor leak issues rather than a clean, improving record. At 166,348 mi the car averages roughly 13,800 mi per year, well above the typical UK passenger‑car usage of around 7,500–10,000 mi annually. This higher kilometre accumulation accelerates wear on consumables such as tyres, brake pads and suspension components, and it also means the vehicle has spent more time under load, potentially amplifying any existing corrosion or component fatigue. The MOT history shows no large gaps, indicating regular testing, but the mileage suggests the drivetrain and chassis have been subjected to considerable stress. When inspecting the vehicle, verify that the nearside rear tyre is replaced with a tyre of the correct size and load rating, and feel for any soft spots or irregularities on the sidewall that could indicate hidden damage. Examine the front engine bay for signs of oil seepage around the valve cover, oil filter housing and oil pan gasket; persistent oil spots on the bonnet or under the car would confirm the advisory and could presage bearing or seal wear. Check the front brake pads for thickness – the 2022 advisory about thin pads means they may be near the minimum limit and could require replacement soon, so listen for any high‑pitched squeal or pedal pulsation under braking. Confirm that the nearside front headlamp illuminates correctly on dipped beam and that all direction indicators flash at the required rate; any intermittent operation could point to wiring or bulb issues that were previously flagged. During a test drive, monitor for any vibration or pull when cornering that might hint at worn suspension bushes or uneven tyre wear, and listen for unusual noises from the rear wheel area that could indicate a developing tyre or rim problem. Addressing the tyre bulge, oil leak and brake pad wear before purchase will be essential to bring the car back to a road‑worthy state.
