2018 Audi Q3 2.0L Diesel · MD18 AEX

The 2018 Audi Q3 is currently roadworthy, the most recent MOT on 16 January 2026 recording 80 615 miles with no defects. The maintenance trend shows improvement; the only recorded faults were a rear‑brake disc wear advisory and rear‑tyre uneven wear in June 2022, and a single‑mile tread‑depth failure in June 2021, both of which have not reappeared in the three subsequent annual tests. The vehicle’s recent service history indicates a stable, defect‑free condition. Mileage accumulation relative to the vehicle’s age tells a story of reduced usage over time. Over eight years the car has logged roughly 80 000 miles, averaging about 10 000 miles per year historically. However, the increase from 76 280 miles in January 2025 to 80 615 miles in January 2026 represents only 4 335 miles in an 11‑month period, a marked slowdown compared with the 17 475 mile jump between June 2021 and June 2022. The 11‑month gap between the 2025 and 2026 MOTs is within legal limits but suggests the car has been stored or lightly driven for extended periods. Earlier years show higher annual mileage, indicating more intensive use before the recent decline. For a prospective buyer, the key areas to inspect in person centre on the components that have shown wear. The rear brake discs were flagged as worn, pitted and scored (not seriously weakened) in June 2022; a visual check should confirm they are not excessively thin or corroded and that the calipers operate freely. The rear tyres displayed uneven or castellated wear on the inner shoulders, a symptom often linked to suspension bushings or alignment issues; a suspension walk‑around should assess for worn bushings, coil‑spring condition and wheel‑bearing play. Tread depth on all tyres, especially the front tyres that failed the 2021 test, must be verified against the 1.6 mm legal minimum. Finally, a thorough under‑body inspection for rust or corrosion is advisable, given the vehicle’s age and the previous brake‑disc pitting, to ensure structural integrity remains intact.
