2.1L OM651 DE22 LA FWD (105kW)
Diesel
During your test drive, listen carefully for any hesitation or surging when accelerating at low speeds, as the EGR valves on these OM651 engines can become clogged with carbon deposits, or the plastic intake manifold may develop hairline cracks.
Pay close attention to the gear changes while driving; if the shifts feel firmer than expected, it is worth noting that transmission solenoids or fluid degradation can occasionally occur in the 9G-TRONIC unit as these cargo vans accumulate mileage.
Check the vehicle's handling on wet or steep terrain; being a W910 FWD chassis, it features a larger turning circle than RWD versions and can experience front tire spinning when pulling away under load on typical hilly NZ streets.
Check the underside and engine bay for any signs of weeping fluids, specifically around the water pump and oil cooler area, as gaskets in these high-workload diesel engines frequently require replacement as part of long-term upkeep.
Usually a great time to ensure the transmission fluid and filter have been refreshed, and to check the single-row timing chain for any slack or rattling during a cold start.
Consider having a specialist inspect the DPF (Diesel Particulate Filter) health, overall exhaust system efficiency, and the condition of the plastic intake manifold.
A common interval to check the accessory drive belt, electric power steering rack components, tensioners, and the water pump to ensure reliable operation.
Prioritize high-quality synthetic engine oil changes every 15,000km or annually, whichever comes first, to protect the timing chain.
Regularly drain the fuel filter's water separator to keep the common-rail injection system running smoothly.
Keep an eye on your AdBlue levels and ensure you're using fresh fluid to prevent any crystallization issues in the SCR system.
Periodically inspect your tire wear patterns to ensure your alignment is spot on, which helps extend the life of your front tires on this FWD platform.
Ensure your brake fluid is flushed every two years to maintain optimal stopping power, especially if you're frequently carrying heavier loads.
Estimated repair costs if issues arise
If the vehicle does a lot of short-distance stop-start driving, the DPF may eventually require a professional deep clean or replacement. It is wise to set aside funds for this as the vehicle enters higher mileage territory.
These sensors play a vital role in emissions control. They can sometimes reach the end of their operational life after years of service. It is a good idea to keep this in mind for your long-term vehicle maintenance planning.
Depending on the van's work history, the automatic transmission benefits from a proactive fluid flush. Budgets should also account for potential replacement of leaking water pumps or cracked intake manifolds, which are common OM651 age-related issues.
