2015 BMW 520 2.0L Diesel · AF15 BOS

The most recent MOT test on 2025-06-25 resulted in a passing outcome, with only one minor defect—damaged windscreen that does not impair the driver’s field of vision—and one advisory regarding near-side rear tyre wear approaching the legal limit, specifically showing edge wear. This follows a pattern of consistent MOT results from 2020 to 2024, with no failures or repeated critical issues, suggesting a generally stable maintenance record. The lone failure in 2023—related to non-functional registration plate lamps and a missing nearside front position lamp—was a straightforward electrical issue likely resolved post-test, as no further defects were recorded in subsequent MOTs. While the 2023 advisory on rear tyre wear was noted, it was not present in the 2025 test, indicating either corrective action or a temporary variation in tyre condition. The vehicle’s mileage of 71,523 miles at 11 years old represents a moderate annual usage rate of approximately 6,502 miles per year, which is within the expected range for a car of this age and class. This pace suggests a balanced driving profile without extreme overuse or prolonged periods of inactivity, though the absence of a service history or odometer verification means potential discrepancies cannot be ruled out. Higher mileage would accelerate wear on consumables like brake pads, suspension components, and engine fluids, while lower mileage might indicate standing corrosion—particularly in the wheel arches, undercarriage, and brake systems—due to prolonged exposure to moisture. The 2023 advisory on rear tyre edge wear could imply uneven load distribution or alignment issues, which may have been addressed but warrants further inspection if the buyer proceeds. For a prospective buyer, the most critical areas to inspect during a physical examination include the rear tyres, as the 2023 advisory suggests potential edge wear that could indicate misalignment or suspension irregularities. On a test drive, listen for uneven tyre noise or excessive vibration, which may signal misalignment or camber issues. Additionally, check for any signs of fluid leaks under the vehicle, particularly from the rear axle or suspension components, as this could indicate failing seals or seals. The registration plate lamps and position lamps, which failed in 2023, should be verified for functionality, as electrical faults in these areas can recur if wiring or connectors have degraded over time. Beyond the MOT history, the buyer should conduct a thorough inspection of the vehicle’s structural and fluid integrity. Given the age and mileage, inspect the tyres for sidewall cracking or perishing, which can compromise their safety, especially if the vehicle has been stored for extended periods. Check the 12V battery and starter system for signs of corrosion or poor connections, as older vehicles are more susceptible to electrical failures. Inspect the brake system for corrosion on discs or binding calipers, which can occur from prolonged standing, and verify that brake fluid is at the correct level and free of contamination. Finally, since the vehicle’s service history is not provided, the buyer should request or verify the last scheduled service, particularly for fluid top-ups, filter replacements, and wear item replacements, as these are critical for maintaining performance and roadworthiness.
