2015 Mercedes-Benz E 2.1L Diesel · WAZ 616

The most recent MOT test on 2026-03-13 resulted in a pass, though it included two persistent advisories: the offside rear inner tyre showing significant wear near the legal limit and signs of cracking or perishing, alongside thin near- and offside rear brake pads. This follows a pattern of recurring issues rather than a clear improvement, as the vehicle’s history shows multiple advisories related to tyre wear and brake pad condition over the past three years. The failure in 2022 highlighted critical tyre defects—bulges indicating structural failure risks and a cut reaching the tyre’s ply—which underscore the need for vigilance, particularly given the wear progression observed in subsequent tests. While the vehicle passed most recent inspections, the advisories suggest ongoing wear that could escalate if not addressed promptly, especially given the tyre’s proximity to legal limits. The recorded mileage of 69,614 miles for a vehicle aged approximately 11 years represents a moderate annual usage rate of around 6,329 miles per year, which is within the expected range for a car of this age and class. However, the mileage alone does not fully explain the wear patterns observed in the MOT history, as the vehicle’s condition suggests either prolonged periods of inactivity—leading to standing corrosion and potential fluid degradation—or more aggressive use that accelerates component wear. The rear brake pads showing thin wear and the tyres exhibiting edge wear and cracking indicate that the vehicle has been subjected to regular braking and possibly uneven loading, which can exacerbate tyre and brake system deterioration over time. The absence of a clear spike in mileage between tests suggests steady but not necessarily optimal maintenance, particularly regarding consumables and fluid management. For the prospective buyer, the most critical inspection should focus on the rear tyres, as the advisories and prior failure indicate structural and tread wear risks. Check for any remaining bulges or cracks in the offside rear tyres, and verify that the nearside rear tyre has been fully replaced since the 2022 failure to avoid potential road hazards. During a test drive, listen for uneven braking performance, which could signal worn brake pads or binding calipers, and monitor for vibration or clunking in the rear suspension, which may indicate worn suspension bushes or coil springs. The brake system should be inspected for corrosion on discs and linings, especially if the vehicle has been stationary for extended periods, as this can lead to binding or reduced braking efficiency. Additionally, the near- and offside rear brake pads should be replaced as soon as possible to prevent further wear to the discs and to ensure safe stopping distances. Beyond the mechanical issues, the vehicle’s age and mileage warrant a thorough examination of the electrical and fluid systems. Given the minor repeater light failure recorded in 2023, test all interior and exterior lighting systems, including the headlights, indicators, and rear lights, to ensure compliance with current regulations. The 12V battery should be checked for signs of weakness or corrosion, particularly if the vehicle has been used sparingly, as standing can accelerate battery drain and corrosion on terminals. Fluid levels, including brake fluid, coolant, and transmission fluid, should be topped up and checked for degradation, as fluids can break down over time regardless of mileage. Finally, inspect the vehicle’s service history for any missed or deferred maintenance, such as suspension, exhaust, or emission-related servicing, to ensure long-term reliability and compliance with UK roadworthiness standards. If the buyer is concerned about the tyre advisories, consider replacing the rear tyres immediately to mitigate the risk of failure during use.
