2018 Mercedes-Benz E 1.9L Diesel · AF68 LCU

The latest MOT test conducted on 2nd January 2026 resulted in a pass with no recorded defects. Reviewing the history from 2022 through to the most recent test, the vehicle has maintained a consistent and stable maintenance trend, passing every inspection without any noted failures or advisories. While a clean MOT record is a positive indicator of the vehicle's ability to meet minimum legal safety standards, it is important to note that the absence of advisories suggests that issues have either been proactively addressed or have not yet reached a threshold of visible deterioration that an inspector would flag. The recorded mileage of 138,814 miles indicates significant usage for an eight-year-old vehicle, averaging approximately 17,352 miles per year. This is considerably higher than the UK average, suggesting the car has likely been used for regular long-distance commuting. From a mechanical standpoint, high mileage typically accelerates the wear on consumable components such as suspension bushes, shock absorbers, and braking systems. While high-speed motorway mileage can often be less taxing on the engine and transmission than frequent stop-start urban driving, the cumulative distance covered means that various rubber seals, gaskets, and drivetrain components are likely approaching the end of their standard service life. Because the MOT history is entirely clean, your physical inspection should focus on high-mileage wear patterns that may not yet have triggered an official advisory. During your test drive, pay close attention to the suspension by listening for any dull thuds or clunks when traversing uneven surfaces, which could indicate worn control arm bushes or failing coil springs. Inspect the brake discs for deep scoring or significant lip formation and ensure there is no pedal shudder under heavy braking, which would suggest warped discs or binding calipers. Given the high annual mileage, it is vital to verify the service book stamps to ensure that oil and filter changes have been performed at regular intervals, as consistent lubrication is critical for maintaining the integrity of a high-mileage Mercedes engine. Furthermore, inspect the tyres for uneven wear patterns, particularly on the inner or outer edges, which can signal alignment issues or worn suspension geometry. Check the sidewalls for any signs of perishing or cracking, even if the tread depth appears sufficient. Examine the engine bay for any evidence of fluid leaks from gaskets or seals, as high-mileage engines are prone to minor weeping. Finally, check the health of the 12V battery and ensure all electronic auxiliary systems are functioning correctly, as high-use vehicles can put significant strain on the electrical charging system. A thorough check of the brake fluid and coolant age is also advised, as these fluids degrade over time regardless of the distance driven.
