2021 Audi A5 S Line 35 TDI Mhev S-A 2.0L Diesel · YA70 HCZ

The most recent DVSA MOT test, recorded on 6 August 2025, resulted in a PASS with no defects or advisories noted. The preceding tests, conducted on 15 August 2024 and 27 January 2024, similarly returned clean PASS results with no recorded advisories. This consistent record of unannotated passes over a near two-year window suggests a stable and well-maintained mechanical condition, with no recurring wear items such as tyres, brake components, suspension linkages, or exhaust system elements flagged for attention. For a prospective buyer, this represents the most reassuring type of MOT history, indicating that the vehicle has been kept within roadworthy tolerances at each annual assessment without the inspector identifying components approaching their service limits. With a recorded mileage of 50,110 miles spread over approximately five years, this A5 has averaged around 10,022 miles annually, which sits comfortably within typical usage parameters for a premium diesel automatic of this age. This mileage profile suggests the vehicle has been driven regularly rather than left standing for prolonged intervals, which is mechanically beneficial as it reduces the risk of issues associated with inactivity such as brake disc corrosion, seized calipers, perished rubber components, and 12V battery degradation. Equally, the mileage is not so high as to imply excessive wear on major drivetrain or suspension assemblies for a five-year-old vehicle, though routine consumption of clutches, injector servicing, and dual-mass flywheel condition on a diesel-automatic should still remain on a buyer's radar as the odometer progresses. Given the clean MOT record and steady annual usage, a prospective buyer should focus physical inspection efforts on age- and calendar-related degradation rather than chasing known defects. Tyre sidewalls should be examined closely for perishing or cracking from age, as rubber compounds degrade over time regardless of tread depth; check the DOT date code and confirm even wear across the axles, which would point to healthy suspension geometry and correct tracking. A thorough road test should include listening for any suspension clonks or knocking over uneven surfaces, particularly from the front MacPherson struts, anti-roll bar bushes, and drop links, as these components can deteriorate quietly between MOT tests. Additionally, the test drive should include several firm brake applications from moderate speed to confirm smooth pedal feel and straight-line stopping, as brake discs on a vehicle of this usage profile can develop lipping or uneven corrosion that an MOT brake efficiency test may not fully reveal. Under-bonnet inspection should include verification of recent oil and filter changes via service book stamps, inspection of coolant and brake fluid age (both typically requiring renewal on a two-year cycle regardless of mileage), and assessment of the diesel particulate filter through sustained motorway driving, ensuring no active regeneration warnings or excessive smoke on overrun. The 12V battery, which on modern Audis supports extensive electronic systems including the MHEV architecture and start-stop function, should be load-tested if possible, as a failing battery can generate numerous seemingly unrelated electrical faults. Finally, confirm that the timing belt or chain service interval has been observed (Audi TDIs are chain-driven, but auxiliary belts and tensioners require periodic renewal), inspect the underside for any fluid leaks from the oil sump, automatic transmission sump, or coolant pipes, and ensure the vehicle history check corroborates the mileage recorded against the DVSA records to confirm consistency.
