2018 Mercedes-Benz Actros 12.8L Diesel · NK18 WMP

The most recent MOT on 2025-02-05 recorded two minor defects: a lightly corroded rear reservoir (59.4.a.i) and an offside headlamp beam alignment issue (67.1). Both were addressed to pass the test, but the corrosion suggests potential exposure to moisture or road conditions, which could indicate early wear on critical components. The headlamp defect, related to the horizontal cut-off line, may affect visibility and requires adjustment. The vehicle’s MOT history from 2021 to 2024 shows no recorded defects, indicating a period of stable performance. However, the 2025 results introduce the first safety-related issues, suggesting a possible shift in the vehicle’s condition. While the trend is not clearly worsening, the recent defects highlight emerging risks that warrant closer inspection. The vehicle’s mileage of 881,715 miles at 8 years old equates to roughly 110,214 miles per year, which is exceptionally high for its age. This implies significant wear on consumables (e.g., brakes, suspension) and components subject to frequent use. However, the lack of prior defects suggests the vehicle may have been well-maintained or operated under conditions that minimized severe damage. The high mileage raises concerns about long-term reliability, particularly for systems like the drivetrain, brakes, and suspension.
