2015 Audi A4 2.0L Diesel · RO15 ADU

The 2015 Audi A4 shows a stable roadworthiness trend over the past three MOT cycles, with the most recent test on 2025-10-09 at 94,206 miles passing without defects. The single failure in October 2024—just two days before its subsequent pass—was unusual, as no defects were recorded on either attempt, suggesting either a minor administrative oversight or a temporary operational issue rather than a recurring mechanical flaw. The absence of advisories or repeated faults across all tests implies that major systems, including suspension, brakes, and emissions, have not exhibited progressive degradation. However, the lack of any recorded issues does not preclude hidden wear, particularly in high-stress components like coil springs, suspension bushes, or drivetrain joints, which are not always captured in a standard MOT. Mileage progression suggests typical usage for its age, averaging around 8,500 miles annually, though there is a notable gap between the 2022 and 2023 tests, where the vehicle sat idle for nearly a year without movement. This could indicate periods of storage, which may have contributed to minor wear in areas prone to static stress, such as wheel bearings or suspension seals. The rapid accumulation of 9,892 miles between the 2023 and 2024 tests—nearly double the annual average—could imply heavier usage, potentially accelerating wear on consumables like brake pads, tyres, or clutch components if not maintained accordingly. The consistency of mileage readings across tests also confirms the recorded figures are reliable. A buyer should prioritise an in-person inspection of the suspension system, particularly the condition of coil springs, bushes, and shock absorbers, as these are common failure points in high-mileage A4 models. The brakes, though not flagged in MOTs, warrant scrutiny for uneven wear, binding calipers, or excessive corrosion on discs, especially given the vehicle’s age and mileage. Structural integrity should be assessed for signs of corrosion in wheel arches, subframes, or sills, which are often overlooked but critical for long-term safety. Additionally, the exhaust system—particularly around the catalytic converter and oxygen sensors—should be checked for leaks or damage, as these are frequently implicated in emission-related failures. Given the lack of MOT advisories, no major repairs are documented, but a thorough mechanical review remains essential to identify wear not captured in a standard test.
