2016 Mercedes-Benz E220 2.1L Diesel · LS66 ACJ

A consistent record of clean MOT passes across five consecutive annual tests establishes a strong baseline of roadworthiness for this E220, with no advisories, defects, or failures recorded at any point between 2022 and 2026. The most recent examination on 5 March 2026 returned a pass with no defects noted, continuing a pattern that has held since at least 2022. The absence of any corrosion advisories on underbody components, suspension items, or brake lines is particularly relevant for a Mercedes-Benz of this era, given the well-documented propensity for rust to develop around rear subframes, brake pipes, and suspension mounting points. Equally, the lack of steering, suspension, or brake component advisories over the testing period suggests the consumables and structural elements are holding up well within expected service life. Overall, the trend line is stable and favourable rather than showing any progressive deterioration. Against a ten-year vehicle age, the recorded 62,325 miles equates to an average of roughly 6,232 miles annually, which sits squarely within typical parameters for a privately owned executive saloon of this type. The mileage progression between tests is steady and consistent, with no large single-year jumps that would suggest a change of use, such as a long motorway commute or fleet operation, nor any extended gaps indicating a prolonged period off the road. This kind of even accumulation tends to be mechanically kind to components such as the timing chain, turbocharger, injectors, and dual-mass flywheel, all of which suffer more from irregular use or constant short journeys than from steady moderate mileage. The diesel engine and automatic transmission should have been exercised regularly enough to avoid the moisture accumulation and oil contamination issues that plague vehicles used only intermittently. For a prospective buyer, the priority on inspection is to physically verify the condition of the items that do not always show up clearly on a rolling road or ramp test. On a test drive, listen for any clonks or knocking from the front suspension over uneven surfaces, which could indicate worn lower control arm bushes or anti-roll bar drop links beginning to deteriorate, even though no advisories have yet been raised. Feel for any vibration through the steering wheel under braking, as the front discs and pads will be approaching the point where replacement is due given the mileage, and warped discs can introduce noticeable judder. Check that the brake pedal feels firm and that the car pulls up in a straight line, as binding calipers or uneven pad wear are common on E-Class models of this generation. It is also worth inspecting the underside directly for any early signs of surface corrosion on the rear subframe, brake pipes running along the chassis rails, and the exhaust mounting brackets, as these areas can begin to deteriorate before any advisory is triggered. Examine the engine bay for any signs of oil seepage from the valve cover gasket or the oil filter housing, both of which are known weak points on the OM651 diesel unit and can lead to oil contamination of the auxiliary belt and pulleys. Confirm that the automatic transmission shifts smoothly between ratios without hesitation or flaring, and that the diesel particulate filter has no warning lights illuminated, as the DPF on this engine is sensitive to usage patterns and may require attention if the vehicle has been used primarily for short trips. Finally, verify that all electrical systems including the infotainment display, air conditioning, and seat adjustments function correctly, as complex Mercedes electronics can be costly to rectify when faults develop.
