2020 Mercedes-Benz E 1.9L Diesel · WB02 ASH

The most recent MOT test on 08 July 2026 resulted in a pass, but it follows a critical failure for dangerous defects regarding the nearside and offside front tyres. The maintenance trend for this vehicle shows a concerning deterioration in consumable management. While the 2024 and 2023 tests were clean, the 2025 advisory for tyre chunking and edge wear escalated into a dangerous failure in 2026 with cords being exposed. This indicates that tyre maintenance has been reactive rather than proactive, suggesting that components are being operated well beyond their safe service life before being addressed. With 23,763 miles recorded over approximately six years, the vehicle has averaged roughly 3,960 miles per year, which is significantly lower than the UK national average. While this low mileage suggests minimal wear on high-value drivetrain and suspension components, it introduces specific mechanical risks associated with infrequent usage. Low-mileage vehicles often undergo many short journeys that do not allow the engine to reach optimal operating temperature, which can lead to moisture accumulation in the oil and potential carbon deposits within the combustion chamber or exhaust system. During your inspection and test drive, pay close attention to the tyres and wheel geometry. Given the recent history of edge wear and structural failure, you should check for any remaining uneven tread wear and verify that the wheel alignment has been professionally corrected. Listen for any vibration through the steering wheel or rhythmic thumping noises from the front end, which could indicate tyre deformation or suspension issues. Additionally, inspect the brake discs for heavy corrosion or pitting, a common occurrence on vehicles that stand for long periods, and check for any binding or shuddering during braking that might suggest seized calipers. You should also conduct a thorough check of the vehicle's fluids and electrical health. Because the car is driven infrequently, the 12V battery may have experienced deep discharge cycles, so verify its current state of charge and health. Ensure that the service history reflects time-based intervals rather than just mileage; even at low usage, engine oil, brake fluid, and coolant should be replaced every two years to prevent degradation. Finally, inspect the tyres for sidewall perishing or cracking, as rubber can degrade due to age and environmental exposure even if the tread depth remains high.
