2012 Mercedes-Benz E 3.0L Diesel · B3 AOS

A clean and remarkably consistent MOT record defines this Mercedes-Benz E-Class, with the most recent test on 28 October 2025 returning a pass and no advisories or defects of any kind recorded. Across the documented testing history spanning 2023 to 2025, the vehicle has alternated between pass and fail entries, yet critically, none of those failures or passes list any specific component defects, which suggests any failed attempts were either retests following minor items rectified between tests or administrative rather than mechanical issues. The absence of recurring advisories for suspension components, brake wear, corrosion, or exhaust emissions across five recorded tests points to strong structural and mechanical integrity for a car of this age, indicating no chronic deterioration patterns have been flagged by DVSA examiners over the three-year period. At 78,101 miles over roughly 14 years, this E-Class has accumulated mileage at an average rate of approximately 5,579 miles annually, which sits well below the typical usage profile for a vehicle of its vintage and class. This low annual accumulation could reflect a combination of light private use, extended periods of garage storage, or possibly the car having been used predominantly for shorter journeys rather than high-mileage motorway commuting. From a mechanical standpoint, lower mileage reduces wear on major drivetrain components such as the engine, automatic transmission, and turbochargers if fitted, but it can also bring specific concerns including potential ageing of rubber seals, gaskets, and flexible components that deteriorate with time rather than use. The mileage readings across the recorded tests show only modest increments year on year, with no sudden spikes or anomalous gaps that would suggest clock irregularities or extended periods off the road between tests. For a prospective buyer, the lack of recorded advisories means there are no specific components flagged for monitoring, however a thorough physical inspection should still be conducted focusing on areas commonly affected on W212 E-Class models of this age. On a test drive, pay close attention to the suspension behaviour by listening for any clonking or knocking noises from the front struts, top mount bearings, and wishbone bushes over uneven surfaces, as these are known wear items on Mercedes-Benz vehicles regardless of MOT outcomes. Inspect the underside carefully for any signs of subframe corrosion, brake pipe rust particularly along the underbody runs, and any evidence of oil seepage from the engine sump or valve cover gaskets, as these tend to manifest with age rather than mileage. The braking system should be evaluated by checking for any pulling to one side under moderate braking, any vibration through the steering wheel which could indicate disc warping, and ensuring the electronic parking brake operates smoothly without excessive servo noise on application or release. Given the low recorded mileage, it is worth checking the condition of the auxiliary 12V battery and verifying that the vehicle has been regularly serviced, as cars used infrequently can suffer from degraded fuel quality in the system and stale engine oil that has exceeded its calendar life. A compression test or diagnostic scan for any stored fault codes relating to the engine management system, air suspension components if fitted, and the CAN bus network would provide further reassurance. Finally, verify the full service history independently and confirm that all previous advisories, if any exist outside the MOT record, have been addressed, as the absence of MOT advisories does not guarantee that the vehicle has received proper scheduled maintenance throughout its life.
