2017 BMW 640 3.0L Diesel · DC65 COM

The vehicle’s most recent MOT on 2025-06-20 at 74,326 miles recorded a pass with no defects, but the preceding test on 2025-06-18 at 74,304 miles resulted in a fail despite no recorded issues. This pattern of alternating passes and fails without specific defects suggests potential inconsistencies in testing or minimal mechanical degradation. The 2024 and 2023 tests also passed with no defects, indicating a generally stable maintenance record over the past three years. However, the lack of detailed defect reporting limits definitive conclusions about underlying issues. Mileage progression shows steady growth from 45,432 miles in 2023 to 74,326 miles in 2025, averaging approximately 8,258 miles annually, which aligns with typical usage for a nine-year-old vehicle. Notable gaps include a 600-mile increase between the 2024-06-10 fail (58,576 miles) and the subsequent 2024-06-25 pass (59,153 miles), suggesting short-term use or infrequent motoring. The 2025-06-20 test occurred just 12 days after the prior fail, raising questions about the vehicle’s operational status during this period. Overall, the mileage data reflects consistent but unremarkable usage without significant spikes or stagnation. A buyer should prioritise in-person inspection of suspension components, particularly rear coil springs and bushings, given the absence of defect reports despite the recent fail. Brake systems, including caliper binding and disc wear, warrant scrutiny, as these are common issues in older BMWs. Structural corrosion, especially in areas prone to road salt exposure, should also be checked. While the MOT history lacks specific faults, the repeated fails without recorded issues highlight the need for a thorough mechanical assessment beyond the test records.
