2002 BMW M5 4.9L Petrol · FJ02 LGW

A recurring pattern of fluid seepage and tyre wear defines the mechanical profile of this vehicle, despite a relatively clean recent history. The most recent test on 26 January 2026 resulted in a pass, but introduced a new advisory regarding a central rear oil leak, specifically noted as a non-excessive prop seal leak in the rear differential. This follows a period of clean results in 2024 and 2025, yet it contrasts with earlier records from 2019 which flagged front oil leaks and power steering pipe seepage, and 2023 which noted multiple tyres worn close to the legal limit or worn on edges. The vehicle has covered 163,772 miles over its 24-year lifespan, representing an average annual accumulation of approximately 6,824 miles. This usage pattern is consistent with typical age-related mileage, suggesting the car has been driven regularly rather than sitting stationary for extended periods. From a mechanical standpoint, this steady mileage indicates that while the vehicle has not been subjected to extreme high-speed motorway transit, the drivetrain and suspension components have undergone consistent, long-term operational cycles, which aligns with the observed age-related seepage and tyre wear. Prospective buyers should pay close attention to the drivetrain and sealing components during a physical inspection. The advisory from January 2026 regarding the rear differential prop seal requires monitoring to ensure the leak does not progress into an excessive state. On a test drive, listen for any increased rotational noise or whining from the rear differential area, especially under acceleration, which could indicate seal degradation or internal wear. Furthermore, the previous history of power steering hose seepage and front oil leaks suggests that the engine bay and steering rack should be inspected for any residual oil misting or active drips that could indicate aging gaskets or hoses. The 2023 advisories regarding tyre wear on the offside front, nearside rear, and offside rear indicate previous issues with tyre longevity or alignment. While these were passed, a test drive should include checking for any steering pull or unevenness in the handling, which might suggest that suspension bushes or alignment settings have not been fully addressed. Given the history of tyre edge wear, it is advisable to inspect the current tread profiles and sidewalls for any signs of uneven scrubbing, which can be a symptom of worn suspension linkages or incorrect camber settings.
