2012 BMW 520 2.0L Diesel · LS12 UAW

The vehicle is currently roadworthy, though the maintenance trend shows signs of emerging mechanical wear after several years of cleanliness. While the car achieved three clean passes between 2022 and 2024, the most recent test in October 2025 at 147,022 miles identified two defects. The presence of a non-excessive oil leak and a worn nearside suspension arm bush indicates that the vehicle is beginning to require attention consistent with its age and mileage. The mileage pattern is consistent with typical 14-year-old usage, averaging approximately 10,500 miles per annum. The record shows steady usage, with a jump of 9,581 miles recorded between November 2023 and October 2024, and another 12,872 miles between October 2024 and October 2025. This regular interval suggests the vehicle has been used consistently rather than sitting for long periods, which generally benefits the condition of rubber components and seals, despite the high total mileage now on the chassis. A prospective buyer should prioritise a physical inspection of the front suspension to address the worn arm pin bush flagged in the 2025 test. Failure to replace this component can lead to uneven tyre wear and degraded handling. The reported oil leak also requires a close look to determine if it is a simple gasket issue at the valve cover or if it involves a more expensive engine-related seal. Given the lack of structural advisories in the history, the focus should remain on these mechanical wear items and ensuring the leak does not worsen as the vehicle continues to clock miles.
