2021 Audi Q3 Sport 35 Tfsi Mhev S-A 1.5L Petrol · ST21 KXL

The 2021 Audi Q3 Sport 35 TFSI MHEV S-A presents a broadly stable and improving maintenance picture, culminating in a clean pass on 22 December 2025 at 23,868 miles with zero defects recorded. That result marks a notable step forward from the 30 December 2024 test at 20,399 miles, where the tester flagged worn, pitted, or scored rear brake discs on both the nearside and offside. The fact that no brake-related advisory or failure appeared in the most recent test suggests the discs and pads were addressed in the intervening twelve months. The mechanical trend is therefore resolving rather than worsening, and the vehicle currently meets DVSA roadworthiness standards without any outstanding concerns. The mileage profile tells a consistent story of light use. Across roughly five years the car has covered 23,868 miles, averaging approximately 4,774 miles per year, well below the UK typical annual figure of around 8,000 to 12,000 miles. The intervals between tests reinforce this: 17,435 miles in January 2024, 20,399 miles in December 2024, and 23,868 miles in December 2025, representing gains of roughly 2,964 miles and 3,469 miles respectively. There are no suspicious gaps or sudden spikes that would suggest odometer tampering or prolonged periods of disuse. The record is sparse but clean, with only three tests logged, all of which passed. The rear brake disc wear noted in December 2024 is the sole mechanical flag in the entire history. Pitting and scoring on brake discs can stem from prolonged standing, aggressive pad materials, or moisture ingress, all of which are plausible given the low annual mileage. A prospective buyer should inspect the current condition of the rear brake discs, pads, and calipers in person, checking for uneven wear, lipping, or binding. The front braking system, which has never been flagged, still warrants examination given the vehicle's age and the possibility of uneven wear distribution. Tyre condition and age should also be verified, as low-mileage vehicles frequently suffer from perished sidewalls and uneven tread caused by infrequent use rather than high mileage. Beyond the braking system, a brief underside inspection is sensible. With only 23,868 miles over five years, structural corrosion is unlikely unless the car has been exposed to coastal or heavily salted environments. Suspension bushes, coil springs, and shock absorbers should be checked for deterioration, as light use does not eliminate age-related rubber degradation. The mild-hybrid system and eight-speed automatic transmission have no recorded faults, but a road test covering stop-start operation, regenerative braking response, and smooth gear changes remains essential before purchase.
