2015 BMW 640 3.0L Diesel · LL15 TVT

The most recent MOT test conducted on 25 October 2025 resulted in a pass, although it included an advisory regarding a worn rear bracket bush. Evaluating the full history, the vehicle exhibits a stable maintenance trend. While there was a recorded failure in 2019 concerning windscreen wipers and front brake pads, the vehicle has maintained a consistent passing record since then. The recent emergence of advisories for tyres in 2023 and the suspension bush in 2025 indicates that the vehicle is moving into a period where consumable components and rubber bushings are reaching the end of their serviceable life, which is expected for a vehicle of this age. The recorded mileage of 102,901 miles equates to an average annual usage of approximately 9,355 miles. This is considered typical for a vehicle of this age and suggests a balanced usage profile. It avoids the potential issues associated with extremely high mileage, such as premature drivetrain fatigue, while also avoiding the complications of very low mileage, such as fluid degradation or seized components from long periods of inactivity. However, at the 100,000-mile threshold, the vehicle is entering a stage where more intensive mechanical inspections of the suspension, cooling system, and various seals are warranted. On your test drive, you should pay particular attention to the rear suspension integrity. The advisory for the worn rear bracket bush may cause the vehicle to feel unsettled or exhibit a slight knocking or clunking sound when driving over undulations or speed bumps. You should also closely inspect the current condition of all four tyres. Given the history of uneven wear on the rear tyres in 2023, check for any signs of camber issues or uneven tread depletion, which would suggest that the suspension geometry or alignment requires adjustment. Ensure there is no evidence of sidewall perishing or cracking, which can occur over time regardless of tread depth. Finally, perform a thorough check of the braking system. Although the 2019 failure was addressed, you should listen for any squealing or grinding and feel for any vibrations or shuddering through the brake pedal, which could indicate worn or warped discs. Check the brake fluid level and colour if possible, and verify that the service book contains regular stamps to corroborate the MOT history. Given the mileage, it is also advisable to inspect the engine bay for any signs of fluid leaks from gaskets or hoses, as rubber components often become brittle after eleven years of service.
