2019 Audi A7 S Line 45 TDI Quattro Auto 3.0L Heavy oil · RL06 CAM

The most recent DVSA MOT test for this 2019 Audi A7 S Line 45 TDI Quattro was conducted on 16 October 2025, resulting in a pass with no defects or advisories recorded. The previous test on 23 August 2023 also returned a clean pass with no advisory notes logged against the vehicle. With two consecutive examinations producing unblemished results, the documented maintenance trend appears stable, suggesting the vehicle has been maintained to a satisfactory standard for roadworthiness at the points of testing. While the absence of advisories is reassuring, it is worth noting that a clean MOT reflects compliance with minimum legal standards at the time of examination only and does not constitute a comprehensive mechanical inspection. The recorded mileage of 39,520 against a vehicle age of approximately seven years equates to an annual usage of around 5,646 miles, which is notably low for a premium diesel executive saloon of this nature. Such low annual mileage often indicates either predominantly short urban journeys, extended periods of standing, or a combination of both. Mechanical implications of low usage include accelerated degradation of the 12-volt battery due to insufficient charging cycles, increased risk of moisture accumulation in the engine oil from frequent short runs without reaching full operating temperature, and potential degradation of brake fluid, diesel fuel, and coolant beyond their calendar-based service intervals. Conversely, the drivetrain, clutch, and major suspension components are likely to have suffered less mechanical wear than a higher-mileage counterpart. Given the clean MOT record and the low-mileage profile, the prospective buyer should focus on age and standing-related deterioration rather than wear-based defects. Tyres should be examined carefully for sidewall perishing and cracking from age, as rubber compounds degrade through calendar ageing regardless of tread depth, and a tyre older than five years from its DOT date stamp should be viewed with caution. Brake discs and calipers should be inspected for surface corrosion and seizing, as prolonged standing can cause caliper pistons to bind and discs to develop lip corrosion or uneven surfaces; a test drive should be conducted to confirm smooth retardation without shudder or pulling. The diesel particulate filter should be assessed for soot loading by checking whether the vehicle has been used predominantly on sustained runs, as repeated short trips may have compromised its regeneration cycle. Further checks appropriate to this age and mileage profile include verification of the full Audi main dealer or specialist service history, with particular attention to confirmation that brake fluid has been renewed within the recommended two-year cycle, coolant replaced at the prescribed interval, and the timing belt or chain service confirmed as appropriate for the 45 TDI engine. The 12-volt battery should be load tested, as low-mileage vehicles frequently suffer premature battery failure even with relatively recent MOT tests. On a road test, listen for any suspension clonks over uneven surfaces that could indicate perished bushes or top mount wear from age, and observe the quattro system for any unusual transmission behaviour, including hesitant or harsh changes from the automatic gearbox. A pre-purchase inspection by an independent Audi specialist, including a diagnostic scan for any latent fault codes, would be highly advisable given the premium nature of the vehicle and the limited MOT history available.
