2021 Audi A5 S Line 35 TDI Mhev S-A 2.0L Diesel · DA21 ABO

The most recent MOT history for this 2021 Audi A5 S Line demonstrates a stable roadworthiness trend, though the March 2026 test presents an unusual anomaly. The vehicle passed without defects on the 9th of March at 53,470 miles, yet the same day it was also recorded as failed—an inconsistency that suggests either a clerical error or a temporary oversight in the testing process. No advisories or recurring faults were logged in the preceding tests, with the last clean pass occurring in March 2025 at 44,965 miles. This implies the vehicle has not experienced mechanical issues requiring attention between tests, but the duplicate entry warrants verification of the test centre’s records to confirm the vehicle’s true condition at the time. The mileage progression of 10,694 miles annually over five years aligns with typical usage for this model, though the gap between the March 2025 and May 2024 tests—covering 6,792 miles in just over a year—suggests a period of higher activity. Conversely, the absence of any MOT between May 2024 and March 2025 (a 10-month gap) is unusual, as the vehicle would have reached its due date in May 2025. This irregularity could indicate either a temporary storage period or a lapse in MOT compliance, though no advisories in prior tests hint at deferred maintenance. The current mileage of 53,470 miles places the vehicle at the midpoint of its typical lifespan for major components like turbochargers, suspension bushes, and transmission fluids, all of which should be scrutinised during an in-person inspection. Given the lack of recorded faults, the primary focus for a prospective buyer should centre on high-wear items that are not routinely inspected under MOT standards. The turbocharger and intercooler, critical to the 3.0-litre TDI engine’s performance, should be examined for soot buildup or oil leaks, particularly given the hybrid-electric system’s potential to mask minor drivetrain inefficiencies. Suspension components—including coil springs, rear stabiliser links, and front strut mounts—are prone to fatigue at this mileage and should be checked for uneven wear or corrosion, especially in the S-Line’s sport-tuned suspension. Binding rear brakes or uneven pad wear would also warrant attention, as would the MHEV battery’s structural integrity, though this is beyond standard MOT scrutiny. Finally, the absence of corrosion advisories in prior tests does not preclude hidden rust in wheel arches or subframes, so a thorough underbody inspection is essential.
