2015 MINI John Cooper Works 2.0L Petrol · CA65 CYL

The vehicle is currently roadworthy following a pass on May 21, 2026, but the maintenance history reveals a recurring trend of engine management and emissions issues. The car failed its previous two tests in 2025 and 2026 due to significant exhaust- failures involving carbon monoxide, hydrocarbons, and lambda readings. Although the vehicle passed the most recent test at 90,871 miles, the persistence of these faults suggests an intermittent combustion issue or sensor failure that has been treated rather than permanently resolved. The mileage pattern is consistent with an eleven-year-old vehicle, averaging approximately 8,200 miles per year. The record shows a steady accumulation of 8,000 miles between May 2024 and May 2025, and another 8,000 miles between May 2025 and May 2026. This regular usage indicates the car has been driven frequently, which is generally beneficial for preventing components from seizing, though the narrow gap between the failures and passes in 2026 suggests the owner only performed the repairs necessary to rectify the emissions failure. A buyer should focus their physical inspection on the exhaust system and fuel delivery components. Given the repeated failures regarding carbon monoxide and lambda limits, a diagnostic check of the oxygen sensors, catalytic converter, and spark plugs is essential to ensure the engine is burning efficiently. Because the car is approaching the 90,000-mile mark, inspection should also account for wear on suspension bushes and control arms, which are common weak points on this model at this mileage. No structural corrosion or brake binding issues were noted in the record, but the emissions health remains the primary technical concern.
