2015 Mercedes-Benz E 2.1L Electric diesel · WN65 LCW

The most recent MOT, carried out on 4 July 2024, was a pass with only a minor fault – an inoperative registration‑plate lamp – which is easily remedied. Over the preceding five years the vehicle has moved from a series of serious safety failures in 2020 (dangerously worn front tyres) and early 2023 (dangerously low rear‑tyre tread and a major off‑side front lower suspension arm wear) to a pattern of only advisory items in the latest tests. This indicates that the owner has addressed the critical defects and that the overall maintenance trajectory is now stabilising and improving, with no dangerous items recorded in the last two years. At 103,463 mi the car averages roughly 9,400 mi per annum, which sits comfortably within the normal usage envelope for a 2015 model. There are no obvious periods of excessive mileage accumulation that would suggest high‑stress operation, nor are there large gaps that would point to prolonged storage. The mileage level is sufficient to have caused normal wear on consumables such as tyres, brake discs and suspension components, but it does not, in itself, raise concerns about premature component failure. The recurring advisory concerning the front lower suspension arm pins and bushes warrants close inspection. On a test drive listen for clunking or knocking when negotiating bumps, especially over uneven road surfaces, and feel for any looseness when applying steering input at low speed. Excessive play in these joints can lead to premature tyre wear, altered camber and reduced handling precision. Given the history of tyre tread loss – dangerous rear‑tyre depth in early 2023 and front‑tyre warnings in 2020 – verify the current tread depth on all four tyres and examine the sidewalls for cracking, bulging or edge wear. Replacement of any tyre approaching the 1.6 mm limit is advisable, and the front brake disc, flagged in 2019 as worn, should be measured for thickness; if it is within a few millimetres of the minimum specification, plan for resurfacing or replacement to avoid shudder under braking. Beyond the specific items above, the car’s age means time‑related checks are essential. Inspect the 12‑V battery for corrosion on terminals and assess its cranking performance, as batteries over ten years often lose capacity. Examine the under‑carriage for rust, particularly around the wheel arches, suspension mounting points and exhaust system, as prolonged standing can accelerate corrosion. Verify that all fluid levels – engine oil, coolant, brake fluid and power‑steering fluid – are at the correct grades and have been changed in line with the manufacturer’s calendar intervals, since fluids degrade even when the vehicle is not heavily used. A thorough visual inspection of the service book for regular oil changes, filter replacements and any documented suspension or tyre work will give further confidence in the vehicle’s overall roadworthiness.
