2010 Audi A4 2.0L Diesel · BA04 EMM

The defining mechanical concern across the MOT history of this 2010 Audi A4 is a clear pattern of recurring brake-related wear, with the rear axle in particular presenting repeated dangerous defects. In January 2025 the nearside rear brake disc was recorded as seriously weakened and the nearside rear brake pads were below 1.5 mm, both classed as dangerous failures, on the same test that also flagged ABS and electronic stability control warning lamp faults. This was not an isolated event; a January 2023 test similarly recorded nearside rear brake pads below 1.5 mm with both rear discs badly corroded, and January 2022 advisories noted rear brake pads wearing thin alongside inner-edge tyre wear on the front axle. The most recent test in March 2025 returned a pass, but only after the dangerous rear brake and ABS/ESC faults had been addressed, and the remaining advisories for two slightly distorted rear road wheels point to further attention needed on the rear running gear. The overall trend over the recorded tests is one of intermittent but repeated front and rear brake component wear, front suspension degradation, and tyre condition issues, with two failed tests in 2024 and 2025 and a third in 2023. The recorded mileage of 119,276 miles across a 16-year old vehicle equates to an average of roughly 7,455 miles per year, which sits broadly in line with typical annual accumulation for a car of this age. The testing history is consistent with regular use rather than long periods off the road, with MOT entries recorded in successive years between 2022 and 2025. There are no extended multi-year gaps in the DVSA record that would suggest the vehicle was laid up, and no sudden unexplained mileage jumps between tests that might indicate inconsistent clocking or unusual usage. From a mechanical perspective this annual mileage is sufficient to generate the kind of wear that the recorded defects describe, particularly on a heavy executive vehicle where brake disc and pad replacement, tyre renewal, and suspension component servicing are part of normal life-cycle maintenance at this accumulated distance. For a prospective buyer, the front suspension should be a priority area for physical inspection, given the January 2022 major failure for an excessively worn front suspension arm bush on the nearside inner location. On a test drive, listen for clonking or knocking noises from the front end over speed humps, rough surfaces, and during full-lock low-speed manoeuvres, and feel for vagueness or knocking through the steering wheel. Push and twist each front tyre at the top and bottom while stationary to detect play in the strut top mounts, and check the inner and outer edges of the front tyres for uneven wear, as the 2022 advisories flagged inner-edge wear and the 2024 advisories recorded the front tyres as worn close to the legal limit. The brake system, particularly the rear axle, warrants close scrutiny in light of three separate rear brake defect entries in 2023 and 2025. On test, the rear caliper carriers, handbrake mechanism, and parking brake efficiency should be confirmed, and the car should be driven at moderate speed with firm pedal pressure to check for any pulling, vibration, or judder under braking. The 2025 rectification of the ABS and ESC warning lamps should be verified by confirming no dashboard warnings illuminate on ignition, and any history of the diagnostic work undertaken should be requested, as persistent ABS module faults on this generation of Audi are not uncommon. Finally, the tyre and wheel condition noted in the most recent pass should be checked directly. Both rear road wheels were recorded as slightly distorted, which can present as a steering wheel vibration, a thumping sensation through the cabin, or uneven tyre wear at speed. Inspect the sidewalls of all four tyres for bulges and confirm tread depth with a gauge, paying particular attention to the front pair which has worn close to the legal limit in multiple tests. A compression test and inspection of the cam belt or chain replacement interval would be prudent given the mileage, alongside a check for any oil leaks from the engine and gearbox, which are not flagged in the MOT record but are typical for an Audi of this age and accumulated distance.
