2021 Audi A5 3.0L Diesel · LS21 UNG

The 2021 Audi A5 presents a clean MOT history, with no defects recorded across its three most recent tests—most recently passing at 71,250 miles in October 2025. This consistency suggests the vehicle has been well maintained under test conditions, though the absence of advisories or minor issues could also indicate either meticulous upkeep or a history of pre-test rectifications. The October 2024 test at 49,669 miles and the February 2024 test at 41,785 miles further reinforce this stability, with no signs of recurring mechanical or structural concerns. Given the high mileage accumulation—around 14,250 miles annually—buyers should still approach this with caution, as such usage typically accelerates wear on components like brakes, suspension bushes, and drivetrain seals, even if these haven’t yet manifested in MOT failures. The mileage pattern reveals a steady, high-usage regime, with roughly 18,000 miles covered between the February 2024 and October 2024 tests, and another 21,581 miles logged in the following year. There are no extended gaps that might suggest prolonged periods of disuse, which could otherwise mask latent issues. The lack of advisories in any test is unusual for a vehicle of this age and mileage, particularly given Audi’s known susceptibility to suspension wear and electrical quirks. This either points to exceptionally rigorous maintenance or selective attention to only the most critical items. Buyers should verify whether past owners adhered to manufacturer service intervals, as even a clean MOT record doesn’t preclude deferred maintenance on non-testable components. Given the sparse MOT history, a prospective buyer should prioritise a thorough pre-purchase inspection, focusing on suspension integrity—particularly the front coil springs, anti-roll bars, and bushings—given the high mileage. The rear brakes should be checked for binding or uneven wear, as Audi’s rear brake-by-wire systems can develop subtle faults over time. Exhaust emissions and DPF functionality (if applicable) should also be verified, as these are not routinely tested but can fail prematurely under heavy usage. Structural corrosion, especially around wheel arches and sills, should be inspected closely, as Audi’s aluminium-intensive bodywork can still suffer from hidden rust in high-mileage examples. Finally, the electrical system—including sensors, lighting, and infotainment—should be tested for intermittent faults, as these are common in Audis and rarely caught by MOT tests.
