2015 BMW X4 2.0L Diesel · CV65 FMK

The vehicle presents a mixed maintenance profile, currently showing an improving trend following a period of frequent consumable and mechanical failures. The most recent test on 13 November 2025 at 164,269 miles resulted in a clean pass with no defects recorded. This follows a more problematic 2024 inspection where the tester flagged multiple worn tyres, a damp rear differential, and thinning brake discs. The transition from several advisories and failures in previous years to a clean pass suggests that recent remedial work has addressed the most pressing mechanical concerns. The vehicle has covered 164,269 miles over its eleven-year lifespan, averaging approximately 14,934 miles per year. This high annual mileage indicates consistent use rather than long periods of inactivity. The data shows significant mileage accumulation between tests, such as the 28,000-mile increase between September 2022 and September 2023. While high mileage typically accelerates the wear of suspension and drivetrain components, the recent clean MOT suggests the vehicle has been maintained sufficiently to keep up with this heavy usage. A prospective buyer should prioritise a physical inspection of the rear differential and the front suspension system. The records show a persistent issue with a rear differential leak or dampness dating back to September 2020, which reappeared in September 2022 and September 2024. Although the 2025 test was clear, the history of fluid leaks warrants a close look for any signs of fresh seepage. Additionally, the 2023 failure involving worn front inner suspension arm bushes indicates that the front-end geometry and bushings are prone to wear under the vehicle's heavy load. The history also reveals a recurring pattern of neglected tyre maintenance. Between 2018 and 2024, almost every MOT inspection flagged tyres worn close to the legal limit or, in the case of the September 2022 failure, tyres with exposed cords. This suggests a pattern of running consumables to their absolute limit rather than proactive replacement. While the current MOT is clear, a thorough check of the tyre brands, tread depth, and alignment is necessary to ensure the current owner has moved away from this previous habit of minimal upkeep.
