2014 Audi Q3 2.0L Diesel · ML14 FCM

The September 2025 MOT at 94,703 miles returned a pass, yet the advisory list expanded meaningfully compared to prior years. Corrosion now affects both rear coil springs in addition to the persistent rear suspension arm corrosion logged on every test since 2023. This progression from arms alone to springs plus arms indicates a worsening rear-end corrosion pattern rather than stable deterioration. The headlamp alignment and levelling faults that caused failures in 2023 and 2024 appear resolved, suggesting targeted remedial work on the lighting system. Overall, the trend is mixed: lighting issues resolved, but rear suspension corrosion deepening. Annual mileage accumulation remains consistent and unremarkable for this 2014 vehicle. The odometer advanced from 83,230 miles in September 2023 to 89,089 miles by September 2024, then to 94,703 miles in September 2025, averaging roughly 5,700 to 5,800 miles yearly. No prolonged stationary periods or suspicious mileage gaps appear in the record. The regular annual testing pattern itself implies continuous use rather than storage or abandonment. A prospective purchaser should prioritise inspection of the rear suspension assembly. The rear suspension arms have carried corrosion advisories across five consecutive tests from 2023 to 2025, and the 2025 introduction of corroded coil springs signals that environmental degradation is advancing beyond surface levels. Coil spring corrosion risks fracture under load, particularly in colder months when metal fatigue accelerates. The rear bushes and mounting points require assessment for structural integrity, not merely surface rust. The front-end suspension and braking systems also demand attention. The September 2023 failure identified worn front suspension arm bushes and scored front brake discs on inner faces; neither component was explicitly retested or flagged subsequently, which may indicate replacement or merely that subsequent testers applied different severity thresholds. A buyer should verify the condition of these front components directly. The headlamp system, now compliant, should still be tested for proper self-levelling function given its history of repeated failures. Tyre condition requires routine verification, as the 2025 nail advisory indicates basic consumable maintenance may be reactive rather than preventive.
