2018 Audi Q3 S Line Edition TDI Quattro 2.0L Diesel · SM18 WNP

OVERALL VERDICT: The most recent MOT on 2025-08-11 passed with no recorded defects, indicating current compliance. However, the maintenance trend shows a worsening pattern in brake components, with significant disc and pad wear escalating from 2023 (worn but not weakened) to 2024 (seriously weakened discs and pads requiring repair). The 2025 pass suggests post-repair resolution, but recurring brake-related advisories since 2022 highlight a potential systemic issue requiring ongoing monitoring. MILEAGE & WEAR PROFILE: The vehicle’s 67,975 miles over 8 years equate to ~8,500 miles annually, aligning with typical usage. However, the 2024 MOT failure at 61,242 miles reveals accelerated wear on brake discs and pads, which were already showing pitting since 2023. This suggests higher-than-average mechanical stress or insufficient maintenance intervals. Tyre wear advisories in 2022, 2023, and 2024 (near legal limits) further indicate consistent under-inflation or aggressive driving patterns, despite the 2025 MOT reporting no tyre defects. CRITICAL IN-PERSON CHECKS: Inspect all four brake discs for scoring, warping, or thinning, with particular focus on front discs given their severe wear in 2024. Verify brake pad thickness and ensure they are not below 1.5 mm, as noted in the 2024 failure. Examine the front coil springs for fractures, as a 2024 advisory flagged a broken nearside front spring. Check reversing lamp functionality and lens integrity, as defects were recorded in 2024 and 2025. Assess the front registration plate for compliance with current standards, as deterioration was noted in multiple tests. Finally, inspect suspension bushes and chassis for corrosion or misalignment, given the quattro drivetrain’s reliance on structural integrity.
