2012 Mercedes-Benz E 2.1L Diesel · LS62 OUF

The most recent MOT test conducted in February 2026 resulted in a pass, but this followed a concerning failure involving both major and dangerous defects. While the vehicle maintained a clean MOT record from 2019 through 2025, the sudden emergence of a dangerous defect regarding rear brake pad thickness and a major defect concerning the Malfunction Indicator Lamp suggests a recent lapse in preventative maintenance. This shift from a flawless history to a failed test indicates that the vehicle's condition has recently deteriorated, moving from a stable maintenance trend to one that requires immediate scrutiny. The recorded mileage of 67,915 miles is notably low for a 14-year-old vehicle, averaging roughly 4,851 miles per year. This low usage profile suggests the car has been used primarily for short trips or has spent significant time stationary. While this typically means less mechanical wear on the engine and gearbox, it introduces specific risks associated with low-use vehicles, such as the degradation of rubber seals, the perishing of tyre sidewalls, and the potential for brake components to seize or corrode due to lack of regular heat cycles and friction. Prospective buyers should pay close attention to the braking system and electrical diagnostics. The advisory for worn rear brake discs, combined with the previous dangerous failure of the brake pads, means the rear braking assembly is nearing the end of its functional life. During a test drive, listen for any metallic grinding from the rear wheels and feel for any shuddering or pulsations through the brake pedal, which could indicate disc warping or uneven wear. Additionally, confirm that the Malfunction Indicator Lamp functions correctly during the ignition sequence; a faulty MIL is a significant safety risk as it prevents the driver from being alerted to critical engine management issues. Given the low mileage, physical inspections should focus on age-related degradation rather than just wear and tear. Inspect the tyres thoroughly for sidewall cracking or perishing, and check the nearside rear tyre for any signs of a slow puncture following the recent advisory. You should also examine the vehicle's service history to ensure that time-based maintenance, such as brake fluid changes and coolant flushes, has been performed regardless of the low mileage. Finally, check the condition of the suspension bushes and the 12V battery, as both are prone to failure in vehicles that are frequently left standing.
