2014 BMW M5 4.4L Petrol · 13 FH

The vehicle is currently roadworthy, holding a clean pass as of 2 September 2025 at 30,253 miles. The maintenance trend shows an improving trajectory regarding a recurring emissions issue. While the car failed the test in August 2023 and again in early September 2025 due to an exhaust Lambda reading outside specified limits, the subsequent pass without any defects indicates that the fault was addressed and rectified before the most recent inspection. The mileage profile is exceptionally low for a twelve-year-old high-performance vehicle, averaging approximately 2,500 miles per year. Data shows significant intervals between tests, with only 922 miles covered between the August 2023 and 2024 tests, and another 554 miles covered in the final year. This low usage suggests minimal mechanical wear on the drivetrain and engine components, but it increases the risk of component degradation due to dry rot, perished seals, and fluid breakdown caused by long periods of standing. A prospective buyer must scrutinize the exhaust system to ensure the lambda sensor failure was not a temporary fix or a symptom of a deeper failing catalytic converter. Given the low mileage, a physical inspection should also check for flat-spotted tyres and perished rubber suspension bushes, which often fail from age rather than use. The brake discs should be examined for surface corrosion or pitting, as low-use vehicles frequently suffer from rust on the rotors when not regularly exercised.
