2015 Mercedes-Benz E 2.1L Diesel · M6 NEA

The vehicle’s most recent MOT test on 2025-11-20 at 48,256 miles confirms it remains roadworthy with no defects recorded, and the preceding test on 2025-09-08 at 48,036 miles also passed without issues. This consistency over the past year suggests a stable maintenance pattern, though the single failure in 2024—an advisory-only rejection on 2024-09-25—was resolved by the subsequent test two days later. No major recurring faults appear in the record, and the absence of advisories in recent tests indicates no ongoing concerns with suspension bushes, coil springs, or binding calipers. However, the 2024 failure, despite being non-fatal, warrants scrutiny of whether minor issues were overlooked or deferred. The recorded mileage of 48,256 miles over 11 years—approximately 4,387 miles annually—is unusually low for a vehicle of this age, particularly given the Mercedes-Benz E’s typical wear patterns. The gap between the 2023 test at 40,292 miles and the 2024 failure at 45,554 miles represents a 5,262-mile period with no MOT activity, which could imply extended periods of inactivity or limited use. This low mileage may mitigate some wear concerns, but it also raises questions about fluid changes, such as brake fluid, power steering, and differential oil, which can degrade even in stationary vehicles. The lack of advisories in recent tests does not guarantee these fluids have been serviced, so their condition should be verified independently. Given the clean MOT history, the primary focus for an in-person inspection should centre on consumable components that are not routinely tested under the MOT regime. Tyres, despite no recorded failures, should be examined for uneven wear or low tread depth, as the 2023 and 2024 tests did not specify tread measurements. The suspension—particularly rear bushes and coil springs—remains a silent risk; while no advisories were issued, prolonged low mileage could mask subtle deterioration. Brake discs and pads, though not flagged, warrant inspection for thickness and uniformity, especially if the vehicle was stationary for extended periods, as moisture and corrosion can accelerate wear. Finally, the underbody should be checked for corrosion, particularly around the sills, subframe, and exhaust system, as rust is a common silent progression in older Mercedes-Benz models.
