OM 473 - 15.6L Inline-6 (460kW - Updated Euro 6)
Diesel
Monitor the Powershift 3 automated transmission during low-speed crawling; if you notice any jerky engagement or hesitation, it is worth asking the seller about the clutch actuator health and recent calibration history.
Cycle through the Multimedia Cockpit screens while stationary; check for any persistent fault codes or 'Check Engine' warnings related to the ACM (Aftertreatment Control Module), which can be sensitive on these Euro 6 systems.
Engage the PTO (if equipped) while idling to ensure smooth operation, as issues with the hydraulic interface or pump engagement can be a sign of heavy previous workload.
Inspect the air suspension leveling sensors for signs of road grime or physical damage; an uneven ride height suggests the electronic leveling system might require a calibration or sensor replacement.
Consider a major inspection of the OM 473's cooling system components and water pump integrity.
Typically the interval where heavy-duty maintenance on the DPF and Selective Catalytic Reduction (SCR) system becomes a focus for ongoing efficiency.
Often the time to evaluate the state of the turbocharger and potential wear on the high-pressure fuel injection system components.
Keep a consistent log of your AdBlue usage to ensure the SCR system remains within optimal efficiency parameters.
Regularly clean the cab air intake filters to prevent debris from impacting the climate control and cabin air quality.
Perform a visual inspection of the air brake lines and couplings for any minor leaks, which is good practice in our NZ climate.
Stick to the manufacturer's recommended oil change intervals using the specific low-ash synthetic oil required for the OM 473 engine.
Check the condition of the electrical harnesses near the chassis pivot points to ensure no wire chafing is occurring.
Estimated repair costs if issues arise
Given the complexity of the Euro 6 emission hardware, it is prudent to set aside funds for a professional particulate filter clean or potential sensor replacement to maintain fuel efficiency.
As the Arocs is a heavy-duty workhorse, the automated clutch system sees significant use. Should the transmission software require a deep re-learn or the actuator require replacement, it is worth having a buffer ready.
Over time, the rubber bellows in the air suspension can perish. If the truck begins to lose pressure overnight, you should eventually budget for replacing these components axle-by-axle.
