2018 BMW 6 Series 3.0L Diesel · CL68 ASK

The most recent MOT test conducted on 23 December 2025 resulted in a pass, continuing a consistent trend of successful inspections since 2021. The overall maintenance profile appears stable, as the vehicle has avoided any major failures or structural defects. However, there has been a gradual increase in minor advisories over the last three years, transitioning from a completely clean record to notes regarding consumable wear and a missing wheel nut, which suggests the vehicle is now entering a phase where routine component replacement is required. The recorded mileage of 73,003 miles over approximately eight years indicates an average annual usage of roughly 9,125 miles. This is considered typical for a vehicle of this class and age, suggesting a balanced use profile. This level of mileage is generally beneficial as it avoids the pitfalls associated with long periods of standing, such as binding calipers or perished seals, while remaining low enough to avoid the premature fatigue of major drivetrain components or extensive interior wear. Prospective buyers should pay close attention to the braking system, as the MOT history shows a pattern of wearing thin brake pads on both the front and rear axles between 2023 and 2024. It is essential to verify if these pads and the corresponding brake discs have been replaced. During a test drive, the buyer should listen for any metallic grinding or squealing and feel for brake shudder or a spongy pedal, which would indicate neglected maintenance or degraded brake fluid. Additionally, the recent advisory regarding a missing wheel nut and a previous nail in the tyre necessitate a full inspection of all wheel fasteners and a check for any sidewall bulges or substandard puncture repairs. Given the vehicle's age and mileage, a physical inspection of the suspension bushes and coil springs is recommended, as these components often begin to degrade on heavy luxury tourers around this mileage threshold. Any clunks or knocks when traversing uneven surfaces may indicate worn control arm bushes. The buyer should also verify the service history for calendar-based fluid changes to ensure engine longevity. Finally, check the condition of the 12V battery and the charging system, as the complex electronic architecture of the 6 Series is sensitive to voltage drops, which can trigger spurious dashboard warnings if the battery is nearing the end of its service life.
