2004 Audi A3 2.0L Diesel · OW53 OOV

The vehicle passed its most recent MOT test on 15 May 2026, although the examiner recorded three advisories that warrant close attention. The most recent test is part of a generally stable pattern of passes interspersed with two failed attempts in 2021 and 2023, both of which were addressed and followed by passes. While the failures in 2020 and 2021 included majors such as a binding offside front service brake, an inoperative engine MIL, and split constant velocity boots on the drive shaft, these appear to have been rectified at the time. The fresh advisories concerning rear sub-frame corrosion and corroded suspension arms, although not classed as dangerous, signal the early stages of a deterioration trend that is consistent with the vehicle's age and could progress if not monitored. With 140,235 miles recorded over approximately 22 years, the vehicle has covered around 6,374 miles annually, which is broadly typical for its age and suggests consistent, moderate usage rather than long periods of standing. There are no obvious gaps in the MOT record that would suggest extended off-road periods, and the mileage progression appears steady. This rate of use means that consumable items such as brake pads, discs, tyres, and clutches will have seen regular but not extreme wear, while age-related degradation of rubber and electrical components is likely to be a greater concern than wear from high mileage. The advisories recorded at the 2026 test relate to corrosion on the rear sub-frame and suspension arms. Although the examiner has deemed these not seriously weakened at present, corrosion of this nature tends to progress, particularly in areas exposed to road salt and moisture. A prospective buyer should arrange for the vehicle to be inspected on a ramp to assess the extent of surface corrosion versus any deeper structural concern, paying particular attention to mounting points, bushes, and the integrity of bolt threads. On a test drive, listen for clonking or knocking noises from the rear suspension over uneven surfaces, and check for uneven rear tyre wear which can indicate compromised suspension geometry. The sub-frame condition should also be evaluated for any cracks, flaking, or evidence of previous repair. Beyond the recorded advisories, the vehicle's age dictates that several time-based items demand physical verification regardless of MOT outcome. Tyres should be examined closely for sidewall perishing and cracking, even if tread depth remains adequate, as rubber degrades with age irrespective of mileage. The 12V battery is likely due for replacement given the calendar age, and brake discs may show corrosion pitting or lipping from standing between uses. Coolant, brake fluid, and power steering fluid should all be checked for age-related degradation, with brake fluid in particular being hygroscopic and prone to moisture absorption over a 22-year period. The earlier failures relating to drive shaft CV boots and anti-roll bar linkage dust covers indicate that these flexible rubber components have a history of perishing, so a thorough inspection of all gaiters, boots, and covers is recommended. Finally, given the 2020 advisory regarding an inoperative engine management indicator lamp, it would be prudent to confirm that the MIL illuminates correctly on ignition and extinguishes once the engine is running, and to scan for any stored fault codes that might indicate an underlying emissions or engine management concern.
