2015 Mercedes-Benz E 2.1L Diesel · DK15 ADK

The most recent MOT test conducted in March 2026 resulted in a pass with no recorded defects, which is a positive indicator following a period of mechanical and electronic advisories. Looking at the historical trend, the vehicle experienced a cluster of advisories in 2024 regarding wheel bearing play and lipped brake discs, followed by a specific electronic advisory in 2025 regarding the Pre-Safe function. The return to a clean MOT in 2026 suggests that the previously noted mechanical wear has likely been rectified, indicating a stabilizing maintenance profile, provided the electronic issue has also been addressed or was a transient fault. The recorded mileage of 13,356 miles over an eleven-year period is exceptionally low, averaging just over 1,200 miles per year. While this suggests minimal wear on the engine, transmission, and suspension components, such an infrequent usage pattern carries its own set of risks. Vehicles that spend long periods stationary are prone to issues stemming from lack of movement, such as fluid breakdown, seal drying, and the degradation of rubber components. This mileage profile indicates a vehicle that has likely been used for very short trips or kept in storage, which requires a different inspection approach than a high-mileage commuter car. During your test drive, pay close attention to any electronic warnings on the dashboard, specifically regarding the Pre-Safe system mentioned in the 2025 advisory. If the system is malfunctioning, it could affect safety features like tensioning seatbelts or adjusting seats during an imminent collision. You should also listen for any humming, droning, or grinding noises that change with vehicle speed, which would indicate that the wheel bearing play noted in 2024 was not adequately resolved. Furthermore, test the brakes for any shuddering or vibration through the pedal, which would suggest that the lipped discs were not replaced and are now causing uneven friction. Given the low usage, you must conduct a rigorous physical inspection of consumables that age by time rather than distance. Check the tyres thoroughly for sidewall cracking or perishing, as old rubber can lose grip and structural integrity regardless of tread depth. Inspect the brake calipers for signs of binding or corrosion, which often occurs when a vehicle is not driven frequently enough to clear debris and prevent oxidation. Finally, verify the service history to ensure that oil, brake fluid, and coolant have been changed according to the manufacturer's time-based intervals rather than solely on mileage, as stagnant fluids can become acidic or lose their protective properties over time.
