Mercedes-Benz E350 SPT CDI Bluecy 265 A 3.0L Heavy oil · PLZ 300

A clean MOT record across eight tests since 2018 forms the defining mechanical story of this Mercedes-Benz E350, with every entry returning a pass and no advisories or defects recorded against any component. The most recent test on 30 October 2025 returned a pass with no defects, and the sequence shows a single failed attempt on 19 September 2024 that was followed just nine days later by a clean pass on 28 September 2024. No defects were logged against that earlier failure within the official record, meaning the rectification was completed and signed off within the same month. Across all eight recorded tests spanning approximately seven years, there is no pattern of recurring advisories relating to suspension, braking, corrosion, or exhaust components, which is a notable absence for a diesel executive saloon of this age. The recorded mileage of 51,254 miles against a first test in May 2018 places the average usage at approximately 6,400 miles per year, a modest annual accumulation consistent with mixed commuter and longer-distance use rather than high-mileage fleet operation. The testing history has been broadly annual from 2019 onwards, with the only notable gap being between the 2021 test in November and the prior 2019 entry, though this in itself is not unusual for vehicles held on a SORN declaration or used very lightly during that period. The mileage progression cannot be fully verified between individual tests as intermediate readings are not provided in the MOT history, but the overall figure sits comfortably within expected parameters for a diesel automatic of this type and does not raise immediate concerns about clock discrepancies or prolonged storage that could affect drivetrain condition. Given the diesel powertrain, sustained motorway use at moderate annual mileage typically allows the engine and associated emissions systems to reach and maintain proper operating temperature, which is beneficial for turbo, DPF, and EGR longevity, although this cannot be confirmed solely from MOT data. With no test failures linked to exhaust emissions, smoke, or diesel-specific components across the record, there is no documentary indication of DPF, turbo, or injector concerns at the time of testing. Although no specific advisories or component defects have been flagged in any of the eight tests, a prospective buyer should still focus inspection on areas typical of E-Class diesel models approaching this age and mileage. On a test drive, listen for any clonks or thuds from the front suspension over uneven surfaces, particularly from the lower control arm bushes and the front subframe mounting points, as these are known wear items on the W212 chassis and would not necessarily generate an MOT failure in their early stages. Check for uneven tyre wear across the front axle, as worn camber or thrust arm bushes can produce inside-edge wear without causing an immediate test failure. Under braking, feel for any pedal vibration or judder that could indicate front disc warping, and listen for any grinding or scraping from the caliper carriers that might suggest seized slider pins, again a common issue on this model. With the vehicle being a CDI Bluetec diesel, it is worth confirming that the dashboard displays no warning lights relating to the AdBlue system, DPF regeneration cycles, or emissions, and that the car completes a sustained run without entering limp mode. Finally, inspect the underside for any surface corrosion around the rear subframe, brake pipe unions, and exhaust mounting brackets, as the absence of corrosion advisories on the MOT history is reassuring but does not preclude early-stage surface oxidation developing between annual tests.
