2016 Mercedes-Benz B-Class 2.1L Diesel · AM61 PEN

The mechanical picture presented by this 2016 Mercedes-Benz B-Class is one of consistent roadworthiness, with four consecutive recorded passes at its annual examinations since 2022. While one failure is logged on 14 May 2022, no specific defects were recorded against it, which typically indicates a retest was conducted shortly after the initial presentation once an item was addressed, or that the failure was administrative in nature rather than structural. Notably, the absence of any advisories across the available history is unusual for a ten-year-old vehicle and signals that wear items such as tyres, brakes, suspension components, and corrosion-prone areas have remained within serviceable limits at each test point. The most recent pass on 13 May 2025 confirms this trend continued at the latest inspection, giving a prospective buyer reasonable confidence that the car has not accumulated latent mechanical issues that testers have been flagging repeatedly. Recorded mileage stands at 65,172 miles across roughly a decade of use, equating to an annual accumulation of approximately 6,500 miles, which is broadly typical for a family-oriented B-Class of this age. There are no significant gaps in the testing history or abrupt changes in recorded mileage that would suggest long periods off the road or inconsistent use. This steady, moderate usage pattern is mechanically favourable, as it avoids both the corrosion risks associated with low-mileage or laid-up vehicles and the accelerated wear on suspension bushes, brake components, and drivetrain parts that come with very high annual mileages. The car appears to have been in regular service, which generally benefits seals, gaskets, and fluid longevity on a Mercedes of this generation. Despite the clean advisory history, a prospective buyer should still prioritise a close inspection of areas commonly affected on W246-generation B-Class models as they age beyond the ten-year mark. The front suspension, particularly the lower control arm bushes and anti-roll bar drop links, are known to deteriorate and can produce knocking noises over uneven surfaces or when turning at low speed. On a test drive, listen for clonking or rattling from the front wheels over speed bumps and during full-lock manoeuvres, and feel for vagueness or vibration through the steering wheel that could indicate worn top mount bearings or tie rod wear. The rear suspension should also be checked for any sagging or uneven ride height, which may point to weakened coil springs. Braking performance warrants particular attention, as even when discs and pads pass an MOT with adequate remaining material, binding calipers or warped front discs can develop between tests. On the test route, test the brakes from speed and feel for any juddering through the pedal or steering wheel, and listen for scraping or squealing that persists under light application rather than disappearing. Given that this is a Mercedes product with turbocharged and emissions-controlled engines depending on variant, a thorough cold-start observation is advisable to check for excessive smoke, coolant smells, or any ticking from the timing chain area. Finally, although no corrosion advisories appear in the record, an underside inspection for surface rust on subframe, brake lines, and suspension arms is prudent, as rust issues often progress between MOTs without immediately failing a test. A pre-purchase inspection by a Mercedes specialist or a main dealer would provide the clearest confirmation of the vehicle's underlying mechanical state beyond the official test record.
