2020 Audi S5 Edition 1 TDI Mhev Quat A 3.0L Diesel · PL70 MUP

The 2020 Audi S5 Edition 1 TDI MHEV presents with a fully clean DVSA MOT history across the four most recent tests, the latest of which was conducted on 12 May 2026 and recorded no defects, advisories, or failure items. With passes also recorded in December of 2023, 2024, and 2025, the maintenance trend reads as entirely stable, with no escalation in advisory warnings or recurring component failures that would suggest deferred servicing or progressive wear. While the absence of advisories is reassuring on paper, it is worth noting that on a high-performance Audi of this specification, owners often address minor wear items proactively between tests rather than allowing them to become recordable MOT defects, so the clean record should be viewed as a positive indicator of conscientious ownership rather than an absolute guarantee of mechanical perfection. With 72,405 miles accumulated over approximately six years, this S5 is averaging around 12,068 miles annually, which is notably higher than the typical UK average of 7,000 to 9,000 miles per year. This higher-than-average annual usage means the vehicle has covered substantial ground in a relatively short period, placing greater cumulative demand on the major drivetrain and chassis components than would be expected on a lower-mileage example. Mechanically, this elevated mileage profile typically translates to accelerated wear on the suspension bushes, anti-roll bar links, coil springs, brake discs and pads, and dual-mass flywheel components on the TDI automatic variant. Conversely, the consistent annual running pattern suggests the vehicle has not been left standing for prolonged periods, which is generally beneficial for avoiding issues such as brake disc corrosion, seized callipers, perished rubber seals, and 12V battery degradation that frequently affect cars used only intermittently. Given the absence of any recorded defects, attention during a pre-purchase inspection should focus on age-and-mileage-related items that fall outside the standard MOT pass criteria. The MHEV mild hybrid system, including its 48V lithium-ion battery and associated belt-driven starter-alternator, should be verified for proper operation, and the auxiliary 12V battery inspected for state of health, as these are known to require replacement based on calendar age rather than mileage. The diesel particulate filter should be confirmed as having undergone recent forced regeneration cycles, particularly given the higher annual mileage, and the AdBlue system checked for correct dosing and any stored faults. A diagnostic scan using VCDS or ODIS would be strongly advisable to interrogate all control modules for historic fault codes relating to the quattro drivetrain, MHEV components, and emissions systems, none of which would necessarily surface during a standard MOT roadworthiness test. On a physical road test, particular attention should be paid to any signs of suspension wear that may not yet have triggered an advisory, including knocking or clunking from the front suspension over uneven surfaces, uneven tyre wear suggesting alignment or bush deterioration, and any vibration or shudder through the steering wheel under braking that could indicate disc warping from sustained high-speed use. The automatic gearbox should be assessed for smooth, timely shifts both warm and cold, and a careful listen for any rattle or chatter from the dual-mass flywheel on pull-away from rest is worthwhile. Tyres should be inspected for even shoulder wear across both axles, as the quattro system can mask alignment problems until significantly advanced, and the sidewalls examined for any cracking or perishing given that original equipment tyres from 2020 may well be approaching the end of their serviceable life regardless of tread depth. Finally, verifying a complete and stamped main dealer or specialist service history, particularly evidencing timely replacement of the long-life diesel engine oil, brake fluid every two years irrespective of mileage, and coolant, will confirm that the mechanical condition reflects the unblemished MOT record.
