OM 470 - 10.7L Inline-6 (290kW)
Diesel
Engage the PowerShift 3 automated manual transmission through all gears, feeling for any hesitation or 'hunting' during upshifts, as solenoid wear can occasionally present as delayed engagement.
Monitor the AdBlue system warning lights on startup; ensure there are no lingering messages, as the SCR (Selective Catalytic Reduction) sensors can be sensitive to moisture and corrosion in our humid NZ climate.
While driving on an uneven surface, listen specifically for any rhythmic knocking from the cab air suspension mounts, which can wear over time and affect ride quality.
Perform a cold start and observe the exhaust output; an abundance of white smoke could suggest potential attention required for the EGR (Exhaust Gas Recirculation) valve, which is common in high-hour OM 470 units.
Usually marks the interval for a comprehensive inspection of the turbocharger actuator and secondary fuel filter housing seals.
A common point where operators look at the health of the diesel particulate filter (DPF) and may consider a professional cleaning or sensor calibration to maintain fuel efficiency.
Recommended timeframe to review the state of the cooling system components, specifically the water pump and thermostat housing seals, to ensure continued reliability.
Regularly drain the air system reservoirs to prevent moisture buildup, which protects the complex pneumatic valves.
Keep the AdBlue tank topped up with fresh fluid, as crystallization can occur if the truck sits idle for extended periods.
Stick to the manufacturer's oil change intervals using the specific Mercedes-Benz approved low-ash engine oils to protect the DPF.
Inspect the cab tilt mechanism once a year to ensure the hydraulic pump and locking pins remain well-lubricated.
Periodically check the chassis wiring looms for any chafing points, especially around the axle articulation areas.
Estimated repair costs if issues arise
In high-hour units, the clutch actuator can eventually require replacement or calibration to ensure smooth gear changes. If this component needs attention in the future, the estimated cost in NZ is indicative of specialized parts and diagnostic labour.
These sensors monitor exhaust emissions and can become sluggish as they age. Depending on the car's history, you might eventually need to budget for a sensor refresh to keep the engine management system happy.
To keep that 10.7L OM 470 engine running at its peak, the cooling system is a vital area. If this requires attention in the future, the estimated cost covers the pump, seals, and a full coolant flush.
