2015 BMW 520 2.0L Diesel · AV65 WHP

The BMW 520d has maintained a stable and clean MOT record over the past three annual tests, with no advisories or defects recorded since the January 2023 failure—an anomaly that stands alone without any repeat issues. The January 2026 test at 120,558 miles confirmed the vehicle’s roadworthiness with no concerns, suggesting that whatever minor oversight caused the earlier fail has since been addressed or was a one-off oversight. The absence of recurring advisories on critical systems—such as brakes, suspension, or structural integrity—indicates that major mechanical components have either been well-maintained or have not yet reached a failure threshold. That said, the single failure in early 2023, with no defects specified, raises a minor red flag: without further context, it’s impossible to rule out a test centre error or a trivial issue, but the pattern since then has been flawless. The mileage accumulation of roughly 10,960 miles per year aligns closely with the vehicle’s age, suggesting consistent but not excessive use. The most recent 16,000-mile interval between tests (January 2025 to January 2026) reflects typical annual mileage, while the earlier gaps—such as the 7,000-mile jump between the failed January 2023 test and the February 2023 pass—could imply either a brief period of heavier use or a delay in retesting after the initial fail. There are no signs of aggressive driving or neglect; the steady progression implies the car has been driven regularly but not abused. The lack of advisories on wear items like tyres or brakes further supports this, though mileage alone doesn’t guarantee their current condition. For a buyer, the priority should be a thorough inspection of consumable and high-wear components, even if the MOT history is clean. Given the age and mileage, check the condition of the brake discs and pads—particularly the rear, where binding can be subtle—and verify the suspension bushes, coil springs, and ball joints for signs of wear or leakage. Exhaust emissions and fuel system integrity should also be visually inspected, as these are not always caught in standard MOT tests. While the MOT record suggests no major structural or mechanical risks, the absence of advisories on corrosion or bodywork integrity means a close look at wheel arches, sills, and underbody for hidden rust would be prudent. The single past fail, though unexplained, is not a cause for alarm, but it does warrant confirmation that the issue was resolved—preferably with service records to back it up.
