2014 Mercedes-Benz E 2.1L Diesel · LD14 PLJ

The most recent DVSA test on 6 October 2025 resulted in a clean pass with no advisories or defects recorded, and this outcome is consistent with the prior four consecutive annual tests from 2021 through 2024, each of which also passed without any noted items. A five-year run of unblemished MOT results suggests that, at least at the point of each test, the vehicle has been presented in a roadworthy condition with no apparent underlying structural, braking, suspension, or emissions concerns flagged by the examiner. While the absence of recorded advisories is reassuring, it is worth remembering that the MOT is a minimum legal standard and does not guarantee mechanical perfection; it simply indicates that no immediate failure items were identified at the time of testing. The overall trend therefore reads as stable and well-maintained on paper, though a prospective buyer should still satisfy themselves through independent physical inspection and a thorough test drive. With 252,606 miles recorded on a 2014 vehicle, this Mercedes-Benz E-Class has covered approximately 21,050 miles annually, which is notably above average and firmly into high-mileage territory. The relatively consistent year-on-year accumulation, evidenced by the continuous annual MOT submissions, indicates that the car has been in regular service rather than left standing for prolonged periods, which is generally positive for the preservation of seals, brake components, and drivetrain lubrication. However, high mileage of this nature does place considerable accumulated wear on items not always fully captured in MOT testing, including the automatic transmission torque converter and valve body, engine oil consumption patterns, turbocharger bearings, drive chain or belt longevity (depending on variant), and the cumulative fatigue of mounting bushes and interior trim. Diesel variants in particular should be scrutinised for DPF condition, EGR valve function, and injector balance, while petrol variants warrant attention to timing chain stretch and coolant system sealing. Given the clean MOT history and high but consistent mileage, physical inspection should concentrate on the items most likely to require attention at this stage of the vehicle's life. Tyres should be checked closely for uneven shoulder wear, which can indicate misalignment, worn suspension bushes, or weak dampers; even if legal, a set of premium tyres is an imminent cost. Examine the sidewalls for perishing and cracking from age, as twelve-year-old rubber compounds deteriorate regardless of tread depth. Brake discs and calipers should be inspected for corrosion pitting, seized caliper slide pins, and uneven pad wear, particularly as the car has clearly been used in mixed conditions given the mileage. Lift the bonnet and check the 12V battery for its manufacturing date stamp, as batteries beyond five years of age are increasingly prone to cold-start failure, and inspect the auxiliary belt, tensioner, and coolant hoses for any signs of perishing or weeping. The underbonnet area and underside should be examined for any signs of fluid leaks from the engine, automatic transmission, or power steering system, and the exhaust should be checked for corrosion at the mounting brackets and joints. On the road, a thorough test drive should include careful attention to any suspension clonks or knocks over speed humps and uneven surfaces, which may indicate worn control arm bushes, anti-roll bar drop links, or top mount deterioration. Listen for any transmission shunt, hesitation, or delayed engagement when pulling away, particularly with the gearbox in reverse and Drive, as high-mileage Mercedes automatic gearboxes can develop pressure-related faults. Verify that the engine holds a steady idle when warm, observe any smoke from the exhaust on overrun and under load, and check that the steering remains centred and free of vibration at motorway speeds. Equally important is verification of the documented service history, including evidence of recent automatic transmission fluid and filter changes, differential oil replacement, and timing chain or belt servicing at the correct intervals; a well-documented service book from a Mercedes specialist or main dealer will significantly strengthen the case that this mileage has been managed responsibly rather than merely accumulated.
