2018 Mercedes-Benz Actros 12.8L Diesel · NK18 WLL

The vehicle is currently roadworthy, having passed its most recent inspection on 3 June 2026 at 876,457 miles. Maintenance trends appear stable but show signs of reactive repairs consistent with high-intensity usage. While the latest test identified a worn nearside track rod end and minor damage to the windscreen, these did not result in a failure, indicating that the operator is addressing steering components and glass integrity as they reach the end of their service life. The mileage accumulation is exceptionally high, averaging approximately 110,000 miles per year over the eight-year period. Between July 2025 and June 2026, the vehicle covered over 80,000 miles in just eleven months. This rapid rate of travel places extreme stress on the drivetrain, air suspension system, and heavy braking components. The failure on 29 July 2025 at 795,960 miles highlights a significant brake performance issue where the roller brake test machine failed to meet specified effort requirements, necessitating intervention before the subsequent pass two days later. A buyer must conduct a thorough physical inspection of the front suspension and steering geometry. Given the recorded worn track rod end and the high-mileage profile, checking for excessive play in ball joints, tie rod ends, and steering bushings is critical. The braking system requires a detailed check of the discs and calipers, as the previous failure suggests the system may be nearing limit or experiencing inconsistent performance under heavy loads. Additionally, inspect the chassis and mounting points for structural fatigue or stress corrosion, as the consistent high-mileage operation accelerates wear on heavy-duty frames.
