2009 MINI ONE Clubman 1.4L Petrol · GY09 USH

The vehicle is currently roadworthy, but the maintenance trend shows a recurring struggle with engine combustion and emissions. While it passed its latest test in August 2025 at 60,240 miles, it failed that same session due to an oil leak and excessive exhaust hydrocarbon levels. This mirrors a failure in August 2024 at 56,843 miles where carbon monoxide levels were also excessive, suggesting the engine is experiencing persistent incomplete combustion or sensor issues that have not been fully rectified. At 17 years old, the recorded mileage of 60,240 miles represents a low average of approximately 3,500 miles per year. This low rate of use often leads to age-related degradation of rubber components rather than mechanical wear and tear from distance. Between August 2023 and August 2024, the car covered only 2,685 miles, yet the 2023 test flagged perishing and uneven front front tyres, which indicates the vehicle may sit stationary for long periods, leading to tyre dry rot. A buyer must perform a close physical inspection of the oil leak to determine if it is a minor gasket weep or a more significant valve cover or crank seal failure. The recurring emissions failures necessitate a diagnostic check of the oxygen sensors, spark plugs, and ignition system to ensure the engine is burning fuel efficiently. Given the low mileage and history of perishing tyres, the inspection should also check for cracks in the suspension bushes and perished hoses, as these components fail from age on high-age, low-mileage vehicles.
