2015 Audi A3 1.6L Diesel · E12 OCH

A recurring brake‑disc advisory defines this Audi A3’s MOT narrative; the off‑side rear disc has been flagged as worn, pitted or scored on the latest 29 April 2026 test, and a similar front‑disc advisory appeared in 2023. The same 2026 inspection also recorded a failure for the engine’s malfunction‑indicator lamp, indicating an electronic fault that prevented a clean pass, while the overall result was logged as passed for the remaining items. Earlier records show a single headlamp‑aim failure in 2022 but otherwise clean passes, suggesting the vehicle has largely avoided major safety defects apart from the emerging brake‑disc wear and the recent MIL issue. At 76,445 mi the car averages roughly 6,950 mi per year over its eleven‑year lifespan, a mileage level that sits within normal UK usage patterns. There are no prolonged gaps in the MOT chronology, with annual testing from 2021 through 2026, indicating the vehicle has been on the road consistently rather than sitting idle for extended periods. This steady utilisation means wear on consumables such as brake discs, pads and tyres will be in line with the recorded mileage, but the modest annual run‑off also suggests that any premature component failure is more likely linked to specific defects rather than excessive mileage alone. When inspecting the braking system, pay particular attention to the rear off‑side disc for signs of excessive surface rust, scoring or vibration when applying the brakes, especially at higher speeds. Listen for a high‑pitched squeal that could indicate the front pads are approaching the thin‑pad advisory threshold noted in 2023, and feel for any pulsation in the brake pedal that may betray warped discs. Verify that the brake fluid level is correct and that there are no external leaks from the caliper or brake lines, as undisclosed fluid loss could exacerbate the existing disc wear. The engine‑MIL failure recorded in April 2026 warrants a focused diagnostic check; a fault in the emission control or sensor network can trigger a limp‑mode response, affect fuel efficiency and potentially mask other issues. Confirm that the warning light remains extinguished after a cold start and that the engine runs smoothly without misfires, rough idle or loss of power under load. Additionally, the 2022 headlamp‑aim defect should be re‑checked to ensure proper alignment, avoiding glare to oncoming traffic. Addressing the MIL fault and confirming brake‑system integrity before purchase will provide a clearer picture of the car’s immediate roadworthiness.
