2014 Mercedes-Benz B-Class 1.5L Diesel · WD14 HXT

The vehicle currently presents a roadworthy status with a stable maintenance trend following previous setbacks. The most recent test conducted in November 2025 at 68,572 miles resulted in a clean pass, indicating that the mechanical issues identified in prior years have been successfully addressed. While the history shows a pattern of failing on initial presentations, the subsequent clean sheet suggests the vehicle is currently meeting safety and environmental standards without immediate remedial requirements. The mileage profile is notably low for a twelve-year-old vehicle, averaging approximately 5,700 miles per year. The data shows a significant gap of 12,338 miles between the July 2023 test at 53,042 miles and the July 2024 test at 65,380 miles, followed by another 3,192 miles covered by November. This low annual usage generally implies reduced wear on the drivetrain and engine components, though long intervals between use can sometimes lead to degradation of rubber-based components, oxidation of fluids, or flat spotting on tyres if the car has sat stationary for extended periods. A buyer should focus their physical inspection on the specific areas that caused the failures in 2023 and 2024, as the record does not detail the specific defect codes for those events. Given the age of the B Class, it is vital to inspect for structural corrosion on the underside and suspension mounting points, which are common failure points on this model regardless of mileage. Check the brake discs for any signs of pitting or seized calipers, which often affect vehicles used infrequently for low-speed journeys. Ensuring the suspension bushes and coil springs are free of cracking will confirm if the low-mileage usage has translated into preserved mechanical integrity.
