2015 BMW 420 2.0L Diesel · LC64 VFB

The vehicle’s most recent MOT test on 2026-01-06 confirms it remains roadworthy, though the single advisory for a central rear oil leak—classified as minor and non-excessive—suggests a potential long-term concern if unaddressed. The absence of major failures in the preceding tests indicates a stable maintenance pattern, though the recurring minor issues (tyre punctures, child seat obstruction) imply basic upkeep may have been inconsistent. The latest test’s proximity to today (six months old) is acceptable, though the advisory warrants immediate verification of the leak’s severity and any associated fluid loss. Mileage progression shows steady usage, averaging around 6,000 miles annually, which aligns with typical expectations for a vehicle of this age. The intervals between tests are consistent, with no extended periods of inactivity or rapid mileage spikes. The most notable gap is between the 2021 and 2022 tests, where mileage increased by just 3,406 miles in a year, but this remains within reasonable bounds. There is no evidence of neglect or aggressive driving from the mileage data alone. A prospective buyer should prioritise a thorough inspection of the rear axle and differential area, given the persistent oil leak advisory. The suspension components—particularly rear bushes and coil springs—should be checked for wear or corrosion, as high mileage increases the risk of degradation. Brake systems, including calipers, pads, and discs, should be examined for uneven wear or binding, especially if the vehicle exhibits any pulling or reduced stopping performance. Additionally, the tyres—particularly the offside rear—should be scrutinised for deeper damage or uneven tread wear beyond the MOT’s initial puncture detection. Structural integrity, including underbody corrosion and frame rigidity, should also be assessed, given the vehicle’s age.
