2014 BMW 640 3.0L Diesel · D9 NSO

The 2014 BMW 640 presents as roadworthy with a stable maintenance trend. The most recent test on 4 June 2025 at 94,813 miles returned a pass with no defects recorded, following a clean pass on 10 June 2024 at 84,249 miles. The only blemish in the sequence is a failure on 4 May 2024 at 84,187 miles, yet the tester logged no defects, indicating the car cleared on a subsequent presentation weeks later without recorded rectification. Annual mileage sits at roughly 7,900 miles, typical for a twelve-year-old vehicle. The records show light use between 2022 and 2024, with only about 4,100 miles added across that two-year span, then a sharper 10,500-mile jump to the 2025 test. The DVSA data is sparse, carrying just five entries and no advisories, so the history gives little insight into wear on consumables or hidden corrosion. A buyer should still commission an independent inspection of suspension bushes, coil springs, and brake discs given the car's age and the unexplained 2024 failure. The absence of advisories across all passes means worn tyres, wiper blades, or minor structural rust were never flagged, but that reflects tester discretion rather than guaranteed condition. Verify the 4 May 2024 failure cause through the original test centre, since a no-defect fail often points to a documentation or presentation issue rather than a mechanical fault. Check underneath for chassis corrosion and confirm the rear calipers are free, as standing periods in 2022 to 2024 can seize handbrake mechanisms on a 6 Series of this era.
