2015 Audi Q3 1.4L Petrol · PJ15 UTM

The 2015 Audi Q3 presents a mixed maintenance picture as of its most recent MOT activity in December 2025. The vehicle failed its initial test at 86,684 miles on 15 December 2025 due to rear suspension arms corroded and seriously weakened on both sides, alongside advisories for a light oil misting on the offside front shock absorber and both rear tyres worn close to the legal limit. A retest on the same day at the same mileage recorded a pass, indicating the suspension arms were addressed promptly. This pattern suggests a reactive rather than preventive maintenance approach. The rear suspension corrosion advisory first appeared in December 2024 at 79,507 miles as "not seriously weakened" but escalated to a dangerous failure within twelve months, a clear worsening trend that a diligent owner would have monitored or addressed earlier. The mileage progression tells a consistent story. From 62,642 miles in December 2022 to 71,734 miles in December 2023, then 79,507 miles in December 2024, and finally 86,684 miles in December 2025, the vehicle has covered roughly 7,800 miles annually. This is typical for an eleven-year-old vehicle and indicates regular use rather than long periods of inactivity. The annual testing pattern is clean with no gaps, giving confidence that the recorded history is complete and the odometer reading is credible. Buyers should focus their physical inspection on the rear suspension components. The rear lower suspension arms have shown progressive corrosion across multiple tests, and while the December 2025 retest passed, the severity of the initial failure raises questions about the quality of any repairs and whether the nearside and offside arms were replaced with genuine or pattern parts. The offside front shock absorber has displayed a light oil misting advisory consistently since at least December 2022 at 62,642 miles. Five years of the same advisory without replacement suggests the unit is seeping fluid and will eventually require attention. Check for uneven tyre wear on the rear axle, as both rear tyres have repeatedly worn close to the legal limit with edge wear noted, indicating possible tracking or alignment issues. The rear brake discs and pads have also shown wear across multiple inspections, so inspect for lipping, scoring, and pad thickness. Finally, verify the structural integrity of the rear subframe and suspension mounting points, as corrosion in this area on a thirteen-year-old vehicle can compromise long-term safety if left unchecked.
