2015 Mercedes-Benz E 2.1L Diesel · FP65 CEO

The vehicle most recently passed its MOT on 10 October 2025 with no defects or advisories recorded, and this clean outcome follows an unbroken sequence of passes dating back to 2021. Across five consecutive examinations there are no recorded failures, advisories, or minor defects, indicating a stable and well-maintained trajectory from a roadworthiness perspective. The absence of recurring issues around suspension components, braking systems, exhaust integrity, or lighting is a positive indicator for a prospective buyer. Given that no advisories have been flagged in any of the recent tests, there is no specific defect trend to investigate further in the official record. With approximately 60,334 miles recorded over eleven years, this E-Class has covered an average of around 5,485 miles annually, which is notably low for a vehicle of this age and segment. Such underutilisation can suggest either genuine light use or extended periods of standing, both of which carry their own mechanical considerations. Low annual mileage often results in age-related deterioration rather than wear-related wear, meaning components susceptible to calendar degradation may require attention even though mechanical wear items have seen little stress. Equally, prolonged standing can lead to brake disc corrosion, caliper seizure, and flat spots on tyres, all of which may not be immediately apparent during a brief inspection. Although the MOT history is unblemished, a prospective buyer should still undertake a thorough physical appraisal focusing on age-related condition. Tyres warrant close inspection for sidewall perishing and cracking, as rubber degrades chemically over time regardless of tread depth, and any tyres over six years old should be replaced irrespective of legal tread. The 12V battery should be load-tested, as Mercedes-Benz vehicles of this era are sensitive to voltage drop and a weakened battery can cause a range of electrical anomalies. Brake discs should be examined for corrosion pitting or surface lipping caused by infrequent use, and calipers should be checked for binding by ensuring the vehicle rolls straight when the handbrake is released. Coolant, brake fluid, and transmission fluid all degrade over time, so verifying the service book for time-based changes rather than purely mileage-based intervals is essential. On a test drive, particular attention should be paid to the suspension, as low-mileage vehicles can develop perished bushes and weak coil springs that do not always manifest as MOT advisories until they progress. Listen for any clonks or knocks over uneven surfaces, which may indicate worn anti-roll bar links, drop links, or upper and lower control arm bush deterioration. The steering should feel precise and free of vibration, with any vagueness potentially pointing to worn tie rod or idler arm components. Finally, confirm that the engine bay shows evidence of regular servicing through stamps or digital records, and inspect for any oil seepage around the cylinder head cover and oil filter housing, which are known age-related concerns on this generation of Mercedes-Benz petrol units.
