2016 Mercedes-Benz B-Class 2.1L Diesel · YA65 XEP

A recent dangerous off‑side front tyre tear, recorded as a “dangerous” failure on the 6 July 2026 MOT, marks the most significant mechanical event in this B‑Class’s history; the subsequent pass two days later confirms that the tyre was replaced and the immediate safety issue resolved. Apart from that incident, the record shows isolated lamp failures in 2022 and a headlamp aim advisory in late 2023, but otherwise a clean succession of passes, suggesting that the vehicle’s core systems have not exhibited recurring defects. At 51,584 mi for a ten‑year‑old model the annual average sits around 5,200 mi, well below the typical UK usage rate. Such low mileage often translates to reduced wear on engine, transmission and brake components, yet age‑related degradation of rubber seals, hoses and tyre compounds can still be present. The MOT chronology shows no prolonged gaps in testing, indicating the car has been kept on the road regularly rather than stored for extended periods, which mitigates the risk of age‑related deterioration that can accompany long idle spells. When inspecting the car, give priority to the front tyre set: verify tread depth exceeds 1.6 mm on both sides, feel for any soft spots, bulges or sidewall cracking, and listen for thumping or vibration at higher speeds that could hint at hidden damage. Confirm that all registration plate lamps illuminate correctly on both sides, and that the headlamps are correctly centred and free of excessive glare, as past failures suggest these items have required attention. The advisory about an off‑side rear child seat obstructing the adult belt inspection also warrants a visual check that the seat is correctly fitted and that the adult belt can be fully examined and operated without obstruction. Finally, a thorough road‑test should include a short brake application to ensure firm, even pedal feel and the absence of judder, as well as a low‑speed sweep over bumps to detect any knocking from worn suspension bushes or loose steering components. Inspect the wheel arches and under‑body for any signs of corrosion, especially around mounting points, and verify that the exhaust system is securely attached and free of leaks. Addressing these specific points will give a clear picture of the car’s current roadworthiness beyond what the MOT record alone can confirm.
