2015 BMW 640 3.0L Diesel · EF65 YBY

A run of five consecutive passes with no advisories or defects recorded, from 2021 through to the most recent test on 31 August 2026, marks this 2015 BMW 640d as having one of the cleaner roadworthiness histories visible in the DVSA record for its age. The only item of note on the latest pass was a minor advisory for a damaged windscreen that did not obstruct the driver's view, a trivial issue that does not affect structural or mechanical integrity. Prior to that clean stretch, the 2019 and 2020 tests carried advisories relating specifically to inner-edge tyre wear on both axles, suggesting either a sustained geometry issue or a driving pattern that loads the inner shoulders, but no component-level defects or failures were ever recorded against the suspension, steering, or braking systems throughout the entire seven-test sequence. With mileage climbing steadily through the 120,000 range and no structural, corrosion, exhaust, or brake-related advisories appearing, the recorded trend points to a vehicle that has remained compliant at each annual assessment. Annual mileage of roughly 11,200 miles over an eleven-year period sits squarely within typical usage parameters for a luxury GT of this age, and the recorded mileages across consecutive tests confirm a steady, consistent accumulation rather than any long stationary gaps or sudden jumps that might suggest clutch, gearbox, or cooling system stress from infrequent use. The only observable gap is the four-month interval between the September 2020 test and the subsequent one, which is unremarkable and likely reflects scheduling rather than any extended lay-up. With the odometer now showing 123,239 miles, the mechanical implication is that wear-rate components such as brake discs and pads, suspension bushes, coil springs, and the dual-clutch or automatic transmission internals have been worked regularly rather than allowed to seize or degrade through disuse, while still having accumulated significant real-world mileage that warrants close physical inspection of those consumables. For a prospective buyer, the inner-edge tyre wear flagged on the nearside rear in 2019 and the offside front in 2020 is the single recurring theme worth probing. On a test drive, pay particular attention to steering behaviour: any consistent pull to one side, a steering wheel that sits off-centre after straight-line driving, or uneven scrubbing across the rear axle would indicate that the underlying geometry issue, possibly worn rear suspension bushes, trailing arms, or a failing thrust angle, has not been resolved. Listen for clonks or knocks from the rear suspension over speed humps and uneven tarmac, and check whether the rear tyres continue to feather or wear prematurely on the inner edge, as BMWs of this era are known for premature bush wear in the rear carrier and control arm assemblies once mileage passes the 100,000 mark. A four-wheel laser alignment printout from the seller, dated within the last few months, would go a long way to confirming whether the geometry is now within tolerance. Given the high mileage and the fact that no brake, exhaust, or underbody condition has been independently inspected since the 2020 advisories, a thorough physical inspection is strongly advised before purchase. Have the brake discs measured for lipping and minimum thickness, as 123,000 miles will typically have consumed at least one set of front discs and possibly a second, and check the flexible brake hoses and any visible underbody piping for the surface corrosion common to German saloons of this vintage. Inspect the engine bay and undertrays for oil misting or seepage around the valve cover gasket, oil filter housing, and the rear of the engine where the timing cover sits, all known weep points on the N57 diesel at this age. Finally, confirm that the windscreen chip noted on the most recent advisory has not progressed into a crack, and ensure the tyres currently fitted show even wear across the contact patch, as this would corroborate that the geometry concerns raised in 2019 and 2020 have been properly addressed.
