2017 Mercedes-Benz B-Class 1.5L Diesel · FM06 ACM

The vehicle is currently roadworthy having passed its latest MOT in January 2026 at 51,474 miles. However, the maintenance trend shows a pattern of reactive rather than proactive care. While the most recent test resulted in no defects, the vehicle failed just two days prior due to a fractured offside rear coil spring. This indicates that the owner typically addresses mechanical faults only when they result in an immediate test failure, rather than inspecting suspension or rubber components during routine servicing. At approximately 51,474 miles over nine years, this B-Class reflects low annual usage of roughly 5,700 miles per year. The mileage pattern appears consistent, with a gap of about 5,500 miles between the 2024 and 2025 tests, and another 5,800 miles between January 2025 and January 2026. This low mileage explains the recurring issues with rubber-based components, as parts are prone to dry rot and perishing when a vehicle sits stationary for long periods. A buyer must conduct a close inspection of the tyres, as the record reveals a persistent history of neglect from 2022 through 2025. Previous tests repeatedly flagged perishing, cracking, and low tread depth across multiple tyres, culminating in a structural failure of the nearside rear tyre in early 2025. The recent failure of the coil spring in January 2026 further suggests the suspension rubber may be reaching age-related fatigue. You should examine all suspension bushes for signs of tearing and check for deep cracks in tyre sidewalls to ensure the low mileage has not masked significant degradation of essential materials.
