2015 Audi A3 1.4L Hybrid electric · AP65 CVM

A pattern of tyre structure failure and perishing dominates the MOT record, while every other aspect of this A3's mechanical condition has remained consistently clear. The vehicle secured a clean pass with no advisories on 30 June 2026 and again on 12 November 2025, sitting either side of a 4 November 2024 test that recorded matching advisories on both offside tyres for slight cracking or perishing, alongside a minor windscreen chip. More significantly, a Dangerous failure was issued on 21 November 2023 for a nearside front inner tyre bulge caused by structural separation, and a nearside rear outer tyre with exposed ply or cords. The car was presented for retest on the same day and passed with no defects, suggesting both dangerous tyres were replaced prior to re-examination. The recurring theme is concentrated entirely on the offside and nearside tyre walls, with no recorded brake, suspension, exhaust, or corrosion advisories in any of the four completed tests since 2023. At roughly 5,248 miles per year across eleven years, recorded usage is well below average for a 2015 Audi A3, which typically accumulates between 8,000 and 12,000 miles annually. Such low mileage can reflect genuine light use, but it also raises the possibility of extended standing periods, during which brake discs corrode on the friction surface, tyre sidewalls dry and crack from UV exposure, and undertrays and suspension components suffer from lack of regular washing through moving water and grime. There are no significant mileage gaps or unexplained jumps across the test history, with progression between tests appearing broadly linear for an annual tester, so there is no evidence of the vehicle being formally declared off the road for prolonged lay-up. The mechanical implication remains that lightly used consumables such as brake pads, discs, and tyres may have aged chemically even where tread depth remains acceptable. Given the tyre-specific nature of the recorded defects, a close inspection of all four tyres for sidewall perishing, bulges, cuts, and exposed ply should be the primary physical check, paying particular attention to the inner nearside front where the dangerous bulge appeared and both offside tyres that showed cracking on the previous test. Look for small bubbles or ripples in the sidewall under direct light, and check the DOT date code on the sidewall to confirm the tyres are not older than five years, as low-mileage vehicles frequently still run aged rubber. On a test drive, listen for any knocking or clonking over uneven road surfaces that could indicate worn suspension components despite no advisories being recorded, and feel for vibration through the brake pedal or steering wheel under gentle and moderate braking, which may suggest corroded brake disc surfaces from infrequent use rather than pad wear. Finally, inspect the underbody and inner wheelarches for surface corrosion consistent with the vehicle's age, confirm the windscreen chip noted in 2024 has not propagated into the driver's direct line of sight, and verify that the brake fluid and coolant have been serviced within the manufacturer's recommended intervals, as low annual mileage does not exempt these items from time-based degradation.
