2015 Audi A3 2.0L Diesel · PR10 ABY

The most recent DVSA MOT test dated 27 July 2026 resulted in an initial failure on two minor items, specifically a non-functioning nearside stop lamp and a non-functioning nearside rear outer position lamp, both classified as present and obviously failed defects. These items are straightforward electrical bulb or LED module concerns rather than indicators of underlying structural or mechanical deterioration. A subsequent pass was issued on the same date with no defects recorded, confirming that the remedial work was completed satisfactorily prior to re-test. Looking back through the recorded history, the vehicle has passed every annual test cleanly with no advisories, and the only recorded defects are these two trivial lighting failures which are common on aging vehicles and typically reflect nothing more than a blown bulb, a fatigued connector, or in some cases a failing lamp control module. The overall maintenance trend therefore appears stable and reassuring, with no evidence of recurring mechanical, structural, or braking concerns. With 118,276 miles recorded over approximately eleven years, this A3 is accumulating mileage at roughly 10,750 miles per annum, which is broadly typical for a vehicle of its age and indicates regular rather than occasional use. There is a notable gap between the December 2023 test and the January 2025 test, a period of around thirteen months during which the vehicle covered an apparently low mileage before the test programme resumed on a more regular annual cadence. While not unusual, such gaps can occasionally mask intermittent use or short-trip patterns, and it is worth confirming that the recorded mileages are continuous and supported by service documentation rather than any prolonged period of standing which can accelerate corrosion on brake discs, calipers, and underbody components. Given that the MOT record is exceptionally clean and free from advisories, attention should turn to age and mileage related deterioration that the standardised test may not fully capture. At eleven years old and past the 100,000 mile threshold, the timing chain, turbocharger oil feed pipes, DSG or manual gearbox mechatronics seals, and coolant thermostat housings on the TFSI and TDI engines fitted to the A3 are all items that warrant proactive inspection regardless of MOT outcome. On a test drive, listen for any timing chain rattle on cold start, watch for coolant level losses, and ensure that the gearbox selects all ratios smoothly without shudder or hesitation. Brake discs on a vehicle of this age and mileage are likely approaching or past their second set, so check for pulsing under heavy braking and verify there is no scored lip on the disc edges, while also examining the callipers for seized slide pins which commonly cause uneven pad wear. The suspension, particularly the front control arm bushes, anti-roll bar drop links, and rear subframe mounting bushes, should be inspected for perishing and splitting, with attention to any knocking or clonking over uneven surfaces. Tyres on an eleven year old vehicle are particularly susceptible to sidewall perishing and cracking from age, even where tread depth remains adequate, so inspect the sidewalls carefully for fine circumferential cracks and confirm manufacture dates via the DOT stamping on each tyre. The 12 volt battery is almost certainly due for replacement given the calendar age of the vehicle, and a weak battery can produce a host of misleading electrical faults on modern Audi systems. Service history should be verified to confirm that brake fluid, coolant, and automatic transmission fluid if applicable have been changed at their recommended intervals, as these fluids degrade with time rather than mileage and are frequently overlooked by previous keepers. Finally, a thorough underbody inspection is strongly recommended to identify any developing corrosion, oil leaks from the sump, cam chain cover, or turbo, and to confirm the integrity of the exhaust system mounting rubbers, all of which represent predictable wear items on a high mileage premium hatchback of this vintage.
