2021 Audi Q3 Sport 35 Tfsi Mhev S-A 1.5L Petrol · MW21 ACJ

The vehicle most recently passed its MOT on 7 April 2026. The overall maintenance trend appears stable, as the car has maintained a clean record for the majority of its operational life. However, the emergence of a rear brake disc advisory in the latest test indicates that the vehicle is now entering a phase where standard wear and tear components will require attention, marking a shift from the previous defect-free inspections. With a recorded mileage of 24,824 miles over approximately five years, this Audi has been used significantly less than the UK average, averaging roughly 4,965 miles per year. While this low mileage suggests minimal mechanical wear on the engine and gearbox, it often implies periods of inactivity. Such usage patterns can be more detrimental to certain components than consistent long distance driving, particularly regarding the degradation of rubber seals, battery longevity, and the accumulation of surface corrosion on braking surfaces. Regarding the specific advisory for worn, pitted, or scored rear brake discs, the buyer should be aware that this is often a result of surface oxidation from standing rather than heavy frictional wear. During a test drive, listen for any grinding noises from the rear or feel for a slight shudder through the brake pedal under moderate deceleration. If the pitting is significant, the discs may require replacement alongside new pads to ensure optimal braking efficiency and to prevent premature wear of new components. Given the low annual mileage, a thorough physical inspection is essential. Check the tyre sidewalls for fine cracking or perishing, as tyres can degrade due to age even if the tread depth remains legal. Verify the health of the 12V battery and the mild hybrid system, as infrequent short trips can lead to undercharging and premature battery failure. Finally, review the service history to ensure oil and filter changes have been performed according to the manufacturer's time intervals rather than solely by mileage, as engine oil degrades over time regardless of the distance travelled.
