2015 BMW 420 2.0L Diesel · AM64 MCC

The vehicle is road‑worthy according to the most recent MOT on 19 February 2026 at 127,243 miles, but the maintenance trend is beginning to deteriorate, chiefly in the braking system. The tester noted a rear brake disc approaching the wear limit and rear pads thin enough to warrant monitoring, a repeat of the thin‑pad advisory recorded in February 2025, February 2024 and February 2023. Front tyre tread was also close to the legal limit in the 2025 and 2024 tests, suggesting consumable wear is catching up with mileage. No structural or safety‑critical defects were recorded, but the recurring brake advisories indicate a gradual decline. Mileage has risen from 103,150 miles on 25 January 2022 to 127,243 miles on 19 February 2026, averaging roughly 11,500 miles per year – typical for a 2015 BMW 420. The jump of 9,926 miles between the 2022 and 2023 tests reflects a period of higher usage, followed by a slower accumulation of 7,174 miles to the 2024 test and a modest 2,798 miles to the 2025 test. The final increase of 4,195 miles to the 2026 test aligns with the earlier pattern, showing no sudden spikes or prolonged gaps that would suggest neglect. A prospective buyer should scrutinise the rear braking assembly for disc thickness, pad wear and any signs of uneven wear that could indicate caliper binding. Inspect the front and off‑side rear tyres for tread depth, sidewall condition and any edge wear that may have progressed since the last advisory. The off‑side front track rod end ball joint, flagged for slight play in the 2023 and 2025 tests, deserves a hands‑on check for movement and any accompanying suspension bushings or coil spring condition. Finally, verify the exhaust bracket noted in the 2023 test and look for any corrosion or rust on the chassis that could affect structural integrity.
