2013 Audi A4 2.0L Diesel · FX63 LTZ

The 2013 AUDI A4 has demonstrated a pattern of recurring roadworthiness concerns spanning several years, with two consecutive failed MOTs in 2024 and 2025 before returning to a clean pass in March 2026. The primary issues centred on tyre conditions—both front tyres showing severe wear with some edges exposed and near-side tyres appearing worn through—and critical braking system degradation including severely weakened rear brake discs and pads below safe thickness thresholds. While the most recent test on 2026-03-06 cleared the vehicle of defects, the intervening failures indicate that underlying problems persisted throughout the mid-to-late 2020s, creating an inconsistent reliability picture despite the current passing result. With 134,697 miles recorded across 13 years, the average annual consumption of approximately 10,361 miles falls within expected parameters for a vehicle of this age, reflecting moderate daily usage rather than extreme wear. However, the absence of MOT entries between the 2024-04-03 and 2026-03-06 tests represents a significant gap of nearly 18 months with no recorded failures or passes, which may point to extended periods of non-use or infrequent driving. This extended interval compounded by the two prior failed assessments suggests the engine and drivetrain were not under regular stress during that window, yet the subsequent clean pass implies that any accumulated damage was addressed before the latest test, leaving buyers to assess whether the repairs were sufficient or if new issues emerged after the April 2024 failure. The lower suspension arm pin or bush exhibited progressive wear starting around 2022, as evidenced by the advisory noting rear arm movement, and this linkage still requires verification during a test drive as stiffness or play could manifest as a clunking noise over rough surfaces. The rear brake disc condition remains concerning given the original failure report of severely weakened discs and brake pads thinner than 1.5mm, so a test drive should be conducted on varied terrain to detect any pulsating or spongy pedal response indicative of air ingress or remaining hardware failure. Additionally, the rear sub-frame showed corrosion noted in 2021, making it prudent to inspect the frame rails and mounting points for any rust penetration that might compromise structural integrity during cornering loads. Buyers should prioritise a thorough visual inspection of the rear sub-frame for rust progression along the main cross-members and check that all suspension bushings move freely without binding, particularly at the lower arm attachment. The brake system demands a dedicated test drive focusing on deceleration consistency and listening for high-pitched squeal or grinding, especially when applying the brakes firmly while travelling at speed. Given the tyre history, paying special attention to the front tyres' tread depth and sidewall condition will help confirm whether the earlier advices translated into actual road hazards, and checking for any uneven wear patterns that could indicate misalignment or camber issues would provide further confidence in the vehicle's handling characteristics.
