MERCEDES-BENZ B-CLASS2015 · 1.5L Diesel

The 2015 Mercedes-Benz B-Class has a stable roadworthiness record based on its most recent MOT, conducted on 2025-11-07 at 70,368 miles, which resulted in a pass with no defects recorded. The prior test on 2025-11-06 at the same mileage failed, though no defects were logged. This pattern of alternating passes and fails without recorded issues suggests potential administrative errors or minor technicalities rather than mechanical deterioration. The 2024 and 2023 tests also showed no defects, indicating consistent compliance with safety standards over the past three years. The vehicle’s mileage of 70,368 miles at 11 years old aligns with an average annual usage of 6,397 miles, reflecting typical wear for its age. The MOT history shows regular testing intervals, with no significant gaps between assessments. However, the lack of defect records across multiple tests may mask underlying issues, particularly in components like suspension bushes or brake systems, which often degrade gradually. The absence of corrosion or structural concerns in the data is reassuring, but the vehicle’s age necessitates scrutiny of high-mileage components. A physical inspection should prioritise the suspension system for worn coil springs or bushings, which can cause uneven tyre wear and handling issues. The braking system, including calipers and discs, warrants close examination, as binding or uneven wear might not trigger MOT failures. Additionally, the exhaust system’s integrity should be confirmed, as emissions compliance can degrade over time. While the MOT history shows no red flags, the vehicle’s age and mileage justify a thorough check of these critical systems to ensure long-term reliability.
