2015 BMW 640 3.0L Diesel · WO06 BUZ

The 2015 BMW 640 presents as roadworthy with a stable maintenance trend. The most recent test on 3 March 2026 at 123,966 miles returned a pass with no defects recorded, and the three prior annual tests from February 2023 to February 2025 also passed cleanly. The only blemish is a failed test on 14 February 2023 at 90,519 miles, reversed the next day on 15 February 2023 with a pass at the same mileage and no defects listed, which suggests an administrative or procedural rejection rather than a mechanical fault. Mileage has accumulated in a steady, age-typical pattern across the recorded history. From the 15 February 2023 test at 90,519 miles, the car covered 12,233 miles to 102,752 miles by 21 February 2024, then 11,445 miles to 114,197 miles by 19 February 2025, and 9,769 miles to the 3 March 2026 reading of 123,966 miles. Over eleven years this equates to roughly 11,270 miles per year. The record shows no standing gaps or sudden accumulation spikes, and the clean pass history across four years indicates the previous owner kept basic consumables and emissions within limits. Given the absence of any advisories for suspension bushes, brake discs, coil springs, corrosion, or exhaust emissions across the entire MOT sequence, no recurring mechanical trend is evident. A buyer should still commission an independent inspection of structural integrity and drivetrain wear, as the DVSA test does not measure internal engine or gearbox condition. The 2023 same-mileage fail-pass pair warrants a check of the original test refusal reason to confirm it was not a suppressed defect.
