2014 Mercedes-Benz B-Class 1.5L Diesel · TY13 KES

A consistent record of MOT pass results across five consecutive tests, with only minor advisories recorded, points to a mechanically sound B-Class that has not suffered any structural or safety-related failures to date. The most recent examination on 4 March 2026 produced a clean pass with two minor advisories relating to under trays obscuring certain components and slight damage to both rear tyres, neither of which compromised the test outcome. The broader trend is stable, with the only meaningful chassis-related advisory appearing in March 2025 for slight play in the offside front anti-roll bar linkage ball joint, a common wear item on vehicles of this age and mileage. Importantly, there are no recorded advisories relating to brake performance, exhaust integrity, corrosion of structural members, suspension coil springs, steering components, or fluid leaks, which collectively suggest the vehicle has retained its structural and dynamic integrity well into its twelfth year. Recorded mileage of 89,257 miles over twelve years equates to an average accumulation of approximately 7,438 miles annually, a figure that sits broadly within the expected range for a privately owned family MPV of this generation. There are no anomalous gaps in the testing history or sudden surges in mileage between consecutive tests, indicating steady and consistent usage rather than extended periods off the road or unusually high annual mileage that would accelerate wear on the drivetrain, clutch, or braking system. This usage pattern is mechanically favourable: it implies regular warm-up cycles, consistent lubrication of mechanical components, and predictable wear rates on consumables such as brake pads, discs, and tyres. The absence of long lay-up periods also reduces the likelihood of issues commonly associated with stationary vehicles, such as seized brake calipers, deteriorated rubber seals, or moisture ingress in the air conditioning system. For a prospective buyer, the advisory regarding the offside front anti-roll bar linkage ball joint warrants specific attention during a physical inspection and test drive. This component connects the anti-roll bar to the suspension strut via a small joint that gradually develops play as the internal housing wears; although the recorded play was slight at the time of test, such joints can deteriorate noticeably over a twelve-month interval. On a test drive, listen for a clunk or rattle from the front suspension when traversing speed bumps or uneven road surfaces, particularly at low speed, and pay attention to any vagueness or looseness in the front-end response during direction changes. A second test on a rough road surface, such as a section of patched tarmac or cobbled street, will help isolate the noise. If the joint has degraded further, replacement is straightforward and relatively inexpensive, but ignoring it can lead to uneven tyre wear and reduced cornering stability. The rear tyre damage advisory should be examined closely, as slight sidewall or tread damage can develop into a more serious failure if the tyres are nearing the end of their service life. Inspect both rear tyres for any bulges, cuts, or uneven wear patterns, and verify the manufacturing date via the sidewall DOT stamp to ensure they are not aged rubber that has hardened and cracked. During the test drive, assess brake feel and stopping confidence, particularly from higher speeds, as the B-Class can be prone to binding rear calipers if the vehicle has seen predominantly low-speed urban use. Finally, given that the under trays were noted as obscuring components during the most recent test, request that the seller remove them or raise the vehicle on a ramp for a proper visual inspection of the engine underside, subframe, and exhaust system, areas that the MOT tester was unable to fully evaluate.
