2010 Mercedes-Benz B-Class 2.0L Diesel · YP10 BMZ

A consistent run of clean MOT passes from 2022 through 2025 establishes a stable roadworthiness profile for this Mercedes-Benz B-Class, with no advisories, failures, or component defects recorded across the entire inspection history. The only irregularity is a brief failed test on 24 October 2025 immediately followed by a pass on the same date, a pattern that typically indicates a minor administrative or easily rectified item was addressed between the two examinations rather than any underlying mechanical concern. This uninterrupted string of defect-free outcomes suggests the major safety-critical systems, including brakes, suspension, tyres, lighting, and emissions, have remained within DVSA tolerances throughout the vehicle's recent testing life, which is a reassuring baseline for any prospective buyer assessing structural and mechanical integrity. With 100,360 miles accumulated over sixteen years, this B-Class averages around 6,272 miles annually, placing it squarely within typical usage expectations for a vehicle of this age and class. There are no extended gaps in the MOT testing record and no sudden mileage jumps between tests, indicating the car has been in continuous, regular use rather than left standing for prolonged periods. For a diesel or petrol B-Class of this generation, this kind of steady mileage pattern is generally favourable: the engine, gearbox, and drivetrain have likely been kept warm and lubricated through regular operation, and consumable wear on braking components, tyres, and suspension has progressed at a predictable rate. However, at the six-figure mileage threshold, certain age-related wear items on Mercedes-Benz vehicles of this era, such as diesel injector wear, dual-mass flywheel fatigue, and turbocharger actuator play, become increasingly relevant even if not yet flagged at test. When inspecting the car in person, particular attention should be paid to the areas most prone to wear on a high-mileage B-Class that has not yet appeared on an MOT. On a test drive, listen for clonking or knocking from the front suspension, particularly over speed humps and uneven surfaces, as this often points to worn lower control arm bushes, anti-roll bar drop links, or top mount bearings, all common renewal items on W245 platform models. Steering should feel precise and self-centring; any vagueness, knocking on full lock, or uneven tyre wear across the front axle would warrant further investigation into track rod ends and wishbone assemblies. Under braking, check for pedal pulsation or vibration, which on a Mercedes of this age often indicates warped front or rear brake discs, and listen for any grinding or scraping that might suggest worn pads or seized caliper slide pins. Beyond the suspension and braking systems, a thorough inspection should include a careful visual check for oil leaks around the upper timing cover area, oil filter housing, and from the turbocharger oil feed and return lines, as Mercedes diesel units of this era are known for these seepages once mileage climbs past 100,000. On the engine bay level, inspect coolant hoses and the expansion tank for signs of weathering or weeping, and confirm the coolant level is clean and full as a precaution against head gasket concerns. During the road test, allow the engine to reach full operating temperature and verify that there is no excessive smoke from the exhaust, particularly blue smoke on overrun or black smoke under load. Finally, verify that all electrical systems function correctly, including the COMAND unit, climate control, electric windows, and central locking, as electrical gremlins become more common on B-Classes of this vintage. A pre-purchase inspection by a Mercedes-Benz specialist or a thorough independent garage remains highly advisable to give confidence before committing to a purchase at this mileage level.
