2018 Mercedes-Benz E 220 D SE Auto Heavy oil · KM18 AAJ

The most recent MOT test conducted in November 2025 resulted in a pass with no recorded defects. Reviewing the historical data, the vehicle shows a stable maintenance trend, having secured three consecutive clean passes since a single failure in late 2022. The absence of any recorded advisories in the recent testing cycle suggests that the vehicle has been maintained to a standard that avoids the common accumulation of minor wear-and-tear issues typically seen in older vehicles. The recorded mileage of 170,295 miles indicates an average annual usage of approximately 21,287 miles, which is considerably higher than the typical UK average for a vehicle of this age. This high-mileage profile suggests the car has likely been used for significant long-distance or motorway commuting. While this type of usage can be beneficial for keeping diesel components like the diesel particulate filter clear, it also means the vehicle has undergone extensive mechanical cycles. You should anticipate that major wear items, including the turbocharger, fuel system, and automatic transmission, will have seen significant service life and may require closer scrutiny. During your physical inspection and test drive, focus on the mechanical integrity of the suspension and drivetrain. Listen for any knocking or clunking sounds when driving over uneven surfaces, which could indicate worn suspension bushes, perished rubber mounts, or fatigued coil springs. Check the braking system for any shuddering through the pedal or steering wheel during deceleration, which may suggest warped brake discs or binding calipers. Given the high mileage, it is vital to verify the service history to confirm that oil and filter changes have been carried out regularly, as consistent lubrication is critical for the longevity of the E 220 d engine. Furthermore, examine the tyres for any signs of uneven wear, which could point to underlying alignment or suspension geometry issues. Check the engine bay for any evidence of oil or coolant leaks, particularly around the turbocharger and various seals, as high-mileage engines are more prone to gasket and seal degradation. Ensure the automatic gearbox operates smoothly, with seamless gear changes and no signs of slipping or hesitation under load. Finally, check the condition of the battery and ensure all electrical components, including sensors and lighting, are functioning correctly, as high-mileage vehicles can sometimes exhibit intermittent electrical faults due to aged wiring or component fatigue.
