2017 Mercedes-Benz B-Class 2.1L Diesel · KP67 UBL

This Mercedes-Benz B-Class has demonstrated consistent roadworthiness over the past four MOT cycles, with no defects recorded in the most recent tests conducted in September 2025 and September 2024. The vehicle passed all mandatory and advisory items without fail, suggesting that major systems—brakes, suspension, steering, exhaust emissions, and structural integrity—have been maintained at a baseline standard. The absence of recurring advisories or failures implies that previous owners adhered to routine servicing for critical components, though this does not preclude hidden wear or deferred maintenance on non-MOT-tested items like timing belts, differential fluids, or internal suspension wear. The most recent test, at 65,066 miles, aligns with the vehicle’s typical annual mileage of around 7,200 miles, reinforcing a stable usage pattern without aggressive driving or prolonged neglect. The mileage progression reveals a steady accumulation of approximately 6,700 to 7,200 miles annually, which is typical for a vehicle of this age and class. There are no unusual gaps or spikes in mileage between tests, and the consistent intervals between MOTs (approximately 12 months) indicate regular registration and testing. The duplicate entry for September 2022—where the vehicle was tested twice on the same date—may suggest administrative confusion rather than mechanical issues, as both records show a pass with no defects. This pattern does not raise concerns about deferred maintenance or sudden high-mileage accumulation, though it does not confirm whether intermediate servicing was performed between MOTs. Given the clean MOT history, a buyer should prioritise an in-person inspection of high-wear components that are not routinely tested. Focus on the suspension, particularly the condition of rear coil springs and bushes, as these are common failure points in this model, especially after 9 years and 65,000 miles. Check for uneven tyre wear, which could indicate alignment drift or worn suspension components. The brakes should be examined for uneven disc thickness or glazed calipers, as binding or excessive wear often develops incrementally. Additionally, inspect the underbody for corrosion around the wheel arches, sills, and exhaust system, as Mercedes-Benz B-Class models are prone to rust progression in these areas. The absence of MOT advisories does not guarantee these areas are flawless, so visual and functional checks are essential.
