2021 Audi Q3 S Line 35 TDI S-A 2.0L Diesel · RA71 ABZ

The most recent DVSA MOT test for this 2021 Audi Q3 S Line 35 TDI S-A was conducted on 12 December 2024, at which point the vehicle passed with no defects or advisories recorded. The absence of any advisories, warning items, or failure notes on this examination indicates that the braking system, suspension, steering, exhaust emissions, lighting, tyres, and structural components were all considered to meet the minimum roadworthiness standards at the time of test. With only a single MOT entry on file, it is difficult to establish a definitive longitudinal maintenance trend; however, the clean result on a five-year-old diesel Audi is a positive indicator, suggesting the vehicle has not yet accumulated sufficient wear to generate the typical advisories seen on vehicles of this age, such as worn brake pads or corroding discs. A prospective buyer should note that the next MOT is not due until December 2026, meaning there is a considerable period of unverified roadworthiness ahead, and any deterioration in mechanical condition will not be captured by official testing until then. The recorded mileage of 13,610 miles over a five-year period equates to an annual usage rate of approximately 2,722 miles, which is substantially below the national average and considerably lower than what would be expected for a diesel-powered SUV of this class. This low-mileage profile is mechanically significant, as diesel engines, automatic gearboxes, and associated components such as the diesel particulate filter and AdBlue system are engineered to operate most effectively under regular, sustained running. Extended periods of standing or short, infrequent journeys can lead to issues including moisture accumulation within the exhaust system, glazing of the brake pads and discs due to light use, and potential contamination of engine oil and diesel fuel through condensation. Conversely, lower mileage does reduce wear on high-stress components such as the clutch, turbocharger, and suspension bushes, which is broadly advantageous for the longevity of these parts. Given the clean MOT history and the low annual mileage, any prospective buyer should place emphasis on a thorough physical inspection rather than relying solely on documented test outcomes. Tyres should be examined closely for sidewall perishing or cracking, as tyres degrade with age regardless of tread depth, and a vehicle of this vintage should ideally have all four tyres inspected for their date code. The braking system warrants particular attention, as vehicles that have stood for extended periods frequently suffer from corroded brake discs and seized or binding calipers, which can manifest as brake shudder, uneven pad wear, or a pulling sensation under braking. A test drive should include firm brake applications from speed to confirm straight-line stability and consistent pedal feel. Further checks should include a comprehensive inspection of the 12-volt battery, as low-use vehicles commonly suffer from battery degradation due to insufficient charging cycles, and the battery may require replacement even if the vehicle starts without apparent issue. All fluid conditions should be verified, including engine oil, coolant, brake fluid, and automatic transmission fluid, as these degrade over time irrespective of mileage, and a brake fluid test for moisture content is particularly advisable on a five-year-old vehicle. The underbody should be examined for surface corrosion consistent with UK winter road conditions, the exhaust system checked for any signs of corrosion or blowing joints, and the service history verified to confirm that time-based servicing items such as the cambelt, if applicable, and the diesel fuel filter have been attended to. Finally, a diagnostic scan for any stored fault codes within the engine, transmission, and emissions control modules would provide valuable reassurance given the low-mileage operating profile.
