2017 Audi Q3 1.4L Petrol · WF17 LZB

The 2017 Audi Q3 presents a largely stable mechanical picture, with the most recent MOT conducted on 23 October 2025 at 58,898 miles returning a clean pass and zero defects. That result follows a failure just two days prior on 21 October 2025 at 58,895 miles, where the tester flagged exhaust carbon monoxide content at idle exceeding default limits under section 8.2.1.2 (b). The fact that the car passed on the same mileage two days later suggests the issue was addressed quickly, likely a minor emissions-related repair or recalibration rather than a deep mechanical failure. The overall trend across the full record is one of consistent, trouble-free maintenance with only that single blemish. Mileage accumulation tells a straightforward story. Between the October 2022 test at 29,155 miles and October 2023 at 40,134 miles, the car covered 10,979 miles in twelve months. From October 2023 to October 2024, it added another 9,169 miles, and then between October 2024 and October 2025, the increase was 9,595 miles. That is a steady annual rate of roughly 9,500 to 11,000 miles, which is moderate and typical for a vehicle of this age. There are no suspicious gaps or sudden spikes in the odometer record, and the mileage progression aligns naturally with the test dates. The October 2025 emissions failure is the only defect in the entire history, and it was resolved within 48 hours. Still, a buyer should verify the exhaust and emissions system in person. Request documentation for any catalytic converter or lambda sensor work carried out between the 21 October failure and the 23 October retest. A live emissions check during a test drive, particularly at idle and under load, will confirm the repair was effective rather than a temporary fix. Beyond the emissions item, the record is clean enough to suggest no recurring structural or mechanical concerns. At nearly nine years old and 58,898 miles, the car is due for close inspection of consumable wear items. Check the condition of the front and rear brake discs and pads, suspension bushes, and coil springs for any deterioration. Examine the inner wings, sills, and subframe for corrosion, as these areas on the Q3 can develop surface rust over time. The tyre tread depth and age should also be verified, given the mileage rate. Overall, the MOT history supports a well-maintained vehicle with no persistent faults, and the single emissions advisory appears to have been promptly corrected.
