2015 Audi Q3 1.4L Petrol · SG15 AAJ

The 2015 Audi Q3 has demonstrated a mixed but largely stable roadworthiness trend over the past three MOT cycles, though the most recent test on 25 November 2025 at 58,068 miles revealed a recurring rear brake disc issue—now pitted and scored, though not yet critically weakened. The absence of any major advisories or structural failures in the last two tests suggests the vehicle has been kept in functional condition, but the persistence of rear brake wear indicates this component requires close monitoring. The 2022 failure stands out as an outlier, with multiple critical faults—including a split CV joint boot, worn ball joint, and distorted wheel—suggesting either deferred maintenance or a period of neglect. Since then, the vehicle has passed without further major issues, though the rear brake discs remain a consistent point of concern. The mileage progression of approximately 5,279 miles per year aligns with lower-than-average usage for a vehicle of this age, which could imply lighter daily driving or extended periods of inactivity. The gap between the 2022 failure (32,728 miles) and the subsequent 2022 pass (32,730 miles) is anomalous and may reflect either a rapid correction of faults or an error in recording. Beyond that, the intervals between tests—roughly 12 months—are standard, with no abrupt spikes in mileage to suggest aggressive driving or delayed servicing. The low annual mileage does not necessarily correlate with less wear on suspension or drivetrain components, as prolonged standing can accelerate corrosion and degradation in rubber and metal parts. A prospective buyer should prioritise an in-person inspection of the rear brake system, particularly the discs and calipers, given their repeated mention in the MOT history. The offside front suspension—specifically the lower arm ball joint and CV joint boot—was flagged in the 2022 failure, so these should be examined for leaks, excessive play, or corrosion. The distorted offside front wheel from 2022 warrants checking for alignment issues or further wheel damage. Tyre tread depth remains a concern; failing twice on the offside front tyre suggests either basic upkeep was skipped or the wheel was repeatedly fitted with under-spec tyres. Finally, the structural integrity of the subframe and wheel arches should be assessed for signs of rust or impact damage, particularly given the vehicle’s age and the potential for prolonged exposure to moisture.
