2009 BMW X12.0L DIESEL

The vehicle remains roadworthy, though the maintenance trend shows a recent shift toward fluid integrity issues. While the latest test in January 2026 at 145,684 miles passed, it introduced new advisories regarding front tyre wear and non-excessive oil leaks. This follows a pattern of minor leaks noted in 2024, suggesting that seals and gaskets are beginning to degrade as the vehicle ages and accumulates mileage. At 145,684 miles over 17 years, the car averages approximately 8,570 miles per year. This aligns with typical annual usage for a premium SUV of this age. The mileage accumulation is consistent, with a 7,577-mile gap between February 2024 and 2025, and another 4,208 miles between February 2025 and January 2026. This regularity suggests regular operation rather than long periods of standing, which often leads to perished rubber and seized components. A buyer must focus their physical inspection on the recurring oil leak reports. The 2024 test specifically flagged leaks from the sump plug and the rear differential, while the 2026 test noted a general engine leak. These issues require a close look to ensure they are merely weeping seals rather than active failures that could lead to catastrophic engine damage. The advisory for the front inner tyres being worn on the edge also indicates a likely alignment issue or worn suspension bushes, which needs checking to prevent premature replacement of any new tyres.
