2014 Mercedes-Benz E 2.1L Diesel · Y777 ADL

The vehicle’s most recent MOT test on 2025-12-29, at 159,458 miles, confirms it remains roadworthy with no defects recorded. The absence of advisories or repeated failures across the last two tests—including the January 2025 retest at 141,061 miles—suggests no persistent mechanical issues. However, the single failure in January 2025, despite passing the previous test just three days earlier, raises a minor concern over potential oversight or a borderline condition that narrowly escaped detection. Overall, the trend is stable, with no evidence of worsening wear or recurring faults. The mileage progression indicates unusually high annual mileage, averaging around 13,288 miles per year over the past two years. This is aggressive for a vehicle of this age, particularly given the 17,387-mile gap between the 2023 and 2025 tests, which could imply extended periods of non-use or delayed servicing. The rapid accumulation between tests—such as the 8,387 miles covered in just over a year between 2024 and 2025—suggests heavy usage, which may accelerate wear on suspension components, brake systems, and drivetrain elements. Given the lack of recorded defects, the buyer should prioritise a thorough inspection of high-wear items likely affected by the high mileage. Focus on the suspension system, particularly coil springs, bushes, and dampers, for signs of fatigue or excessive play. The braking system warrants close examination, including rear caliper binding (a common issue in Mercedes models) and rear brake disc wear, as these are frequently overlooked but critical for safety. Structural integrity should also be assessed, especially around wheel arches and subframes, for corrosion or stress cracks that might not have been visible during the MOT but could compromise handling. Tyre condition, despite no MOT failures, should be verified, as the high mileage may have pushed tread limits closer than the last test allowed.
