2009 BMW 520 2.0L Diesel · KS09 NBZ

The 2009 BMW 520d has maintained a clean MOT history across all four tests, with no defects or advisories recorded since its most recent inspection on 2025-07-19 at 70,036 miles. This suggests the vehicle has passed all mandatory DVSA checks for brakes, suspension, steering, exhaust emissions, and structural integrity without fail. The consistent pass status implies either diligent servicing or a vehicle that has not yet encountered significant wear in critical systems. However, the absence of advisories or defects does not preclude hidden issues—particularly in high-mileage components like coil springs, suspension bushes, or drivetrain seals—which would require a thorough mechanical inspection. The recorded mileage of 70,036 miles over 17 years (as of 2026) averages approximately 4,120 miles annually, which is unusually low for a vehicle of this age. This pattern is notable for two reasons: first, the sudden spike between the 2022 and 2023 tests, where mileage jumped from 71,644 to 53,410—a discrepancy that suggests either a reset or a significant period of non-use. The latter is plausible given the 11-month gap between the 2022 and 2023 tests, during which the vehicle likely sat idle. The subsequent consistent low mileage accumulation (around 5,500–6,000 miles per year) may indicate limited usage, which could either preserve components or allow for corrosion in exposed areas if the vehicle was stored without protection. Given the lack of MOT defects, a buyer should prioritise an inspection of suspension components—particularly the rear coil springs and bushes—due to the vehicle’s age and mileage. The binding calipers or uneven brake pad wear, though not recorded in MOTs, could develop over time, especially if the vehicle has been stationary for extended periods. Corrosion in wheel arches, sills, or subframe areas should also be examined, as prolonged low mileage can accelerate rust if the vehicle was exposed to moisture or poor storage conditions. Finally, the drivetrain—including the transfer case (if applicable), differential seals, and automatic transmission fluid—should be checked for leaks or degraded performance, as these are often overlooked in low-mileage vehicles but can fail catastrophically with age.
