2012 Mercedes-Benz B-Class 1.8L Diesel · NJ12 XVF

The vehicle presents a concerning roadworthiness profile with a maintenance trend that suggests reactive rather than preventative repair. While it passed its most recent test in October 2024 at 204,800 miles, the tester identified a coolant leak alongside three tyres worn to the legal limit with uneven edges. This indicates a lack of recent attention regarding cooling systems and basic consumables. The progression from steering issues in previous years to fluid leaks now suggests the vehicle is entering a stage of significant component fatigue. At 204,800 miles over 14 years, this B-Class has averaged approximately 14,600 miles per annum, which is significantly above the national average. The record shows heavy usage patterns, particularly between October 2023 and October 2024 when the vehicle covered nearly 10,000 miles in just twelve months. This high annual mileage places immense strain on the drivetrain, suspension, and braking systems, which explains the recurring failures in mechanical link components noted in the MOT history. A buyer must conduct a thorough physical inspection of the steering and suspension geometry. The October 2023 test flagged play in the offside front suspension arm ball joint and the steering rack inner joints, issues that often lead to unpredictable handling and accelerated tyre wear if not rectified. Furthermore, the coolant leak recorded in 2024 requires a pressure test to determine if the source is a simple hose or a more catastrophic failure of the water pump or head gasket. The uneven wear noted on all three tyres in the latest test further points to a persistent wheel alignment issue or worn shock absorbers and bushings. Given the high mileage and age, the inspection should also check for structural corrosion on the chassis and the condition of the brake lines, ensuring that the high-frequency use has not compromised the fundamental integrity of the vehicle's safety systems.
