2015 MINI Cooper 1.5L Diesel · HT15 ABN

The 2015 MINI Cooper’s most recent MOT test on 2025-04-29 at 162,959 miles passed without defects, but the record reveals a concerning pattern of repeated failures at identical mileages in both 2023 and 2024. Each failure occurred on the same test date—2023-06-20 and 2024-06-28—suggesting a systemic issue either unresolved or recurring despite retesting. The absence of specific defect codes in the failed entries complicates precise diagnosis, but the repetition implies a persistent problem, whether mechanical, electrical, or structural. The latest pass in April 2025 indicates the vehicle was deemed roadworthy at that point, though the lack of intervening tests raises questions about whether critical components were addressed or merely masked. The vehicle’s mileage of 162,959 miles over 11 years—approximately 14,800 miles annually—is unusually high for its age, particularly given the MINI’s typical usage patterns. The jump from 121,332 miles in June 2023 to 145,496 miles by June 2024 suggests rapid accumulation, potentially indicating heavy or consistent use. The gap between the 2024 failure and the 2025 pass—nearly a year—also stands out, as it exceeds the standard 12-month MOT interval. This extended period without testing could imply either deferred maintenance or a deliberate attempt to avoid uncovering underlying issues. The lack of any advisory notes in the passed tests further obscures potential wear trends, but the high mileage alone warrants scrutiny of suspension bushes, coil springs, and brake caliper binding, all of which degrade more rapidly under such usage. Given the repeated failures and the vehicle’s age, a buyer should prioritise an independent inspection of the suspension system, particularly the rear axle where binding or uneven wear is common in MINIs. The brakes, though not explicitly flagged, should be checked for uneven pad thickness, warped discs, or corrosion on the caliper slides—especially if the vehicle was driven through wet or salted conditions. Structural integrity is another critical area; inspect the subframe, sills, and wheel arches for corrosion, as rust can compromise the vehicle’s load-bearing capacity. The absence of advisory notes in recent tests does not preclude hidden issues, so attention to the engine bay for oil leaks, the exhaust system for sagging hangers, and the interior for excessive wear on the clutch or gearbox (if manual) would be prudent. The high mileage also suggests consumables like tyres, wiper blades, and brake fluid may be approaching their serviceable limits.
