2020 Mercedes-Benz B 1.3L Petrol · C12 CAC

Recurring tyre wear issues and a recent failure for exposed cords represent the primary mechanical concern within this vehicle's MOT history. While the most recent test on 11 August 2026 resulted in a pass, the record shows a pattern of degradation in tyre tread depth and edge wear, culminating in a dangerous failure in August 2025 where the offside front inner tyre had ply or cords exposed. The most recent advisory regarding the Tyre Pressure Monitoring System (TPMS) being active suggests a potential sensor fault or a pressure imbalance that requires investigation to ensure the system is functioning as intended. The vehicle has covered 39,169 miles over its six-year lifespan, averaging approximately 6,528 miles per year. This usage pattern is consistent with typical light-to-moderate annual accumulation for a vehicle of this age. From a mechanical perspective, this level of mileage suggests that while major drivetrain components may not have reached high-wear thresholds, consumable items such as tyres, brake pads, and suspension bushes will have undergone regular cycles of use. The consistency in annual mileage indicates a steady usage profile rather than long periods of inactivity or heavy, high-intensity driving. A prospective buyer should pay close attention to the steering and suspension geometry during a test drive. The repeated advisories for tyres being worn on the edges, specifically the inside edges noted in 2024 and 2025, can be an indicator of incorrect wheel alignment or worn suspension components such as control arm bushes or tie rod ends. During the test drive, listen for any knocking or clunking sounds when traversing uneven surfaces and check for any significant pulling to one side when the steering wheel is released on a level road. Any unevenness in tyre wear observed on the current set should be treated as a symptom of underlying alignment or suspension issues. Furthermore, the recent advisory regarding the TPMS should be addressed by checking if a warning light remains illuminated on the dashboard. If the system is active, it may indicate a faulty sensor, a slow puncture, or a calibration requirement. Given the previous failure involving exposed tyre cords, a thorough visual inspection of the current tyre sidewalls and tread patterns is essential to ensure there is no further irregular wear or structural damage. Ensure that the steering feels precise and that there is no vibration through the steering wheel at motorway speeds, which could relate to both tyre condition and wheel balance.
