2013 Mercedes-Benz B-Class 1.8L Diesel · WA13 PRZ

A pattern of structural and consumable wear dominates the roadworthiness record of this 2013 Mercedes-Benz B-Class, with two Dangerous failures for fractured road wheels and recurring advisories across braking, suspension, and tyres pointing to a vehicle that has been worked hard across its life. The most recent test on 6 January 2026 was a pass, but it carried four advisories, including worn trailing arm bushes at the rear, nearside and offside rear inner tyres noted as very close to the legal limit, and the ongoing presence of under trays restricting full inspection. A Dangerous failure on 22 January 2025 was recorded against a fractured nearside front inner road wheel, and a separate Dangerous failure on 18 December 2020 noted a fractured offside rear road wheel and a nearside rear wheel with three cracks. Two fractured wheels across the testing history is a notable safety pattern, particularly for a relatively modern monocoque chassis, and should prompt close scrutiny of the remaining wheels, suspension geometry, and any signs of kerbing damage. With 98,370 miles recorded over roughly thirteen years, the vehicle has covered approximately 7,567 miles annually, which is broadly typical for its age and indicates regular rather than occasional use. The MOT testing history shows annual tests from 2020 onwards with no extended gaps, suggesting the car has remained in active service rather than being laid up, and the mileage progression between tests is consistent with steady accumulation. For a Mercedes-Benz B-Class of this vintage and mileage, the recorded wear pattern on friction materials, tyres, and suspension components is largely proportionate, although the repeated brake disc and pad advisories across multiple tests suggest the braking system has required frequent attention, and the rear trailing arm bush wear flagged in the latest MOT may require replacement within the near term. A prospective buyer should focus their inspection on the components specifically flagged in the MOT record. The Dangerous wheel fractures are the most serious item and warrant a thorough check of all four wheels for cracks, distortion, or weld repairs, including the nearside front and both rear wheels previously affected. The fractured wheels can be associated with impact damage or fatigue, so the tyres should be inspected for uneven wear patterns, sidewall damage, or exposed cords, and any kerbing marks on the alloy edges should be noted. On the test drive, listen for clonking noises from the rear suspension over uneven surfaces, particularly as the trailing arm bushes were recorded as cracked and worn, and feel for any vagueness or knocking through the rear axle over speed humps. The front suspension arm bush noted in 2021 should also be checked for renewed wear, as Mercedes multi-link front geometry is prone to gradual bush deterioration. The braking system requires particular attention given the repeated advisories for thin pads at both axles and the recommendation to change discs alongside pads on multiple occasions. On inspection, the brake discs should be checked for lipping, corrosion, and minimum thickness, while the pads should be measured for remaining friction material. Under hard braking, any vibration or judder through the pedal would suggest disc runout or thickness variation. The nearside rear fuel tank strap corrosion flagged in 2020 should also be visually inspected for renewal or worsening, as corroded straps can compromise fuel system security. Finally, the under trays should be removed for a thorough pre-purchase inspection to confirm the condition of the underbody, subframe, and fuel system, as the MOT history indicates these panels have consistently prevented full assessment.
