2020 Audi A5 S Line 35 TDI Mhev S-A 2.0L Diesel · LL70 KHR

The vehicle’s most recent MOT test on 2026-06-04 confirms it remains roadworthy, with no defects recorded at 39,161 miles. However, the preceding failure in October 2025—just two days before passing at 36,499 miles—indicates a recent but resolved engine-related concern, specifically an inoperative or malfunctioning Malfunction Indicator Lamp (MIL). While the 2026 test suggests the issue has been addressed, the proximity of the failure to the pass suggests either a rushed repair or a recurring sensitivity in the emissions or engine management system. The absence of defects in the two preceding passes (2025-11-05 and 2024-10-31) implies the vehicle has otherwise maintained a stable roadworthiness trend, though the 2023 test revealed tyre wear that bordered on the legal limit, a detail worth revisiting. The recorded mileage of 39,161 miles over approximately six years aligns with typical usage patterns for this age, averaging around 6,500 miles annually. There are no extended gaps or abrupt spikes in mileage that would suggest neglect or heavy usage, though the 2023 to 2024 period shows a slower accumulation—from 28,784 to 33,357 miles—indicating a period of lower activity. The most notable outlier is the October 2025 failure, occurring just two days before the subsequent pass, which may reflect either a delayed test or a narrowly avoided failure. Overall, the mileage progression does not raise immediate red flags, but the engine-related anomaly warrants scrutiny. A buyer should prioritise an independent inspection of the engine management system, particularly the MIL and any related diagnostics, given the 2025 failure. The 2023 tyre advisories suggest the front tyres have seen uneven wear, which could point to alignment issues or suspension wear—particularly the coil springs or steering dampers. The suspension bushes and rear brake components should also be examined for binding or excessive wear, as the 2025 failure hints at potential drivetrain or emissions-related concerns that may have broader implications. Structural integrity, including underbody corrosion around the exhaust and wheel arches, should be checked, especially given the vehicle’s age and typical exposure risks. Finally, the battery and electrical connections should be verified, as MIL-related failures often stem from intermittent wiring or sensor faults.
