2011 BMW 520 2.0L Diesel · DL60 AVP

The most recent MOT test on 2026-02-02 confirms the vehicle remains roadworthy, though the preceding history reveals a concerning pattern of repeated failures at identical mileages. The February 2025 and January 2024 tests both show a failed test followed by an immediate retest on the same day, suggesting either a temporary oversight or a recurring but unresolved issue. The lack of defects recorded in the February 2026 pass implies no major mechanical failures have emerged since then, but the proximity of the last test to today (just five months ago) is acceptable for a high-mileage vehicle. The absence of advisories in any test suggests no critical components were left unresolved, though the repeated failures at the same mileage—177,753 and 189,485—raise suspicion of a systematic issue, possibly related to suspension alignment, brake binding, or exhaust emissions that were either overlooked or temporarily rectified. The recorded mileage of 309,087 miles over 15 years equates to an average of 20,606 miles annually, which is unusually high for a vehicle of this age. The gap between the January 2024 and February 2025 tests spans 13 months but covers only 11,753 miles, indicating a period of very light use or storage. Conversely, the 189,485-mile mark was reached in just three months, suggesting accelerated driving between January and February 2025. This erratic pattern could imply inconsistent maintenance intervals or prolonged neglect during low-mileage periods. The most recent 121,087 miles (since February 2026) also suggests active use, but without further tests, it’s impossible to confirm whether wear has accelerated or stabilised. Given the repeated failures at identical mileages, a buyer should prioritise inspecting the suspension system for worn or leaking bushes, corroded coil springs, or misaligned components. The rear brakes were likely the cause of the 2024 and 2025 failures, so binding calipers, uneven wear on discs, or seized wheel cylinders should be checked. Exhaust emissions failures suggest either a faulty lambda probe, catalytic converter degradation, or an inefficient EGR system—these require diagnostic scanning. Structural integrity is less likely to be an issue at this stage, but the underbody should be inspected for corrosion around wheel arches, sills, and the subframe, particularly given the vehicle’s age. Tyre condition, despite no MOT failures, should be verified, as the repeated failures at similar intervals may indicate past neglect of tread depth or pressure monitoring.
