2015 Audi A3 2.0L Diesel · M26 CAT

The Audi A3 passed its most recent MOT on 12 June 2026 at 164,160 miles, one day after a failure on 11 June 2026 at the same mileage. The maintenance trend is worsening. The June 2026 failure exposed rear brake pads below 1.5 mm, rear brake imbalance from nearside lagging, an insecure front undertray, a nearside front inner tyre close to the limit, and an offside front anti-roll bar ball joint dust cover breached. The owner cleared the brake and ball joint items within 24 hours to secure the pass, but left the undertray and edge-worn tyre as advisories. At roughly 14,924 miles per year, this 2015 car shows high use for its age. The record confirms steady accumulation: 120,628 miles in May 2023, 136,308 in June 2024, 148,757 in June 2025, and 164,160 by June 2026. No standing periods or gaps appear. The clean 2023 test suggests reasonable care early on, but the 2024 to 2026 entries show repeated tyre edge wear and escalating brake neglect. The buyer should inspect the rear braking system in person. The June 2026 failure for pad thickness and imbalance points to deferred consumable replacement and possible caliper or adjuster wear. Verify the nearside rear brake no longer lags and that discs are within tolerance. Check the front suspension and undertray. The failed anti-roll bar ball joint dust cover on the offside front must be confirmed sealed, and the insecure undertray properly refitted. Tyre history shows four consecutive years of inner-edge wear across both fronts; examine alignment, bush condition, and remaining tread before purchase.
