2011 Mercedes-Benz B-Class 1.5L Petrol · LR11 YLM

The most recent MOT test on November 29, 2024, confirms the vehicle passed without defects, though it follows an unusual pattern of two consecutive failures in November 2023—both at the same mileage of 90,443—before passing again in November 2022. This suggests a brief period of instability in late 2023, potentially due to a single unresolved issue or a temporary oversight in pre-test preparation. The latest pass, just six months ago, aligns with the standard 12-month MOT cycle, but the repeated failures at identical mileage warrant scrutiny of whether the same component or system was repeatedly overlooked or inadequately repaired. No advisories or defects were recorded in any test, which implies the tester did not identify any latent concerns beyond the two failures in 2023. The recorded mileage of 99,753 miles over 15 years equates to an average of approximately 6,650 miles annually, a rate consistent with typical usage for this age. There are no significant gaps or spikes in mileage between tests, though the two failures in November 2023 at the same mileage—without intervening mileage accumulation—suggest the vehicle may have been stationary or driven minimally during that period. This could indicate either light usage or a temporary storage period, which might have allowed minor issues to persist undetected. The lack of mileage progression between the two 2023 failures is the most notable anomaly in an otherwise steady pattern. Given the repeated failures in November 2023, a buyer should prioritise an independent inspection of the braking system, particularly the rear brakes, as binding or uneven wear was likely the cause of both failures. The tester’s failure to record defects in subsequent tests suggests either a partial or temporary fix, so the rear brake calipers, pads, and hydraulic components should be thoroughly checked for uneven wear, corrosion, or binding. Additionally, the suspension—specifically the rear suspension bushes and coil springs—should be examined for excessive wear or deterioration, as these are common failure points in this model at this mileage. Structural integrity, particularly around the rear subframe and wheel arches, should also be assessed for signs of corrosion or fatigue, given the vehicle’s age and typical exposure to UK road conditions.
