2.1L OM651 DE22 LA (120kW)
Diesel
Test Drive Task: Listen for a 'chirping' sound while idling. | Note: The OM651 engine can occasionally develop an issue with the water pump or alternator pulley, which often presents as a light metallic chirping at idle.
Test Drive Task: Accelerate firmly while in a higher gear (low RPM). | Note: Check for any surging or hesitation; in older examples, it's common to consider the condition of the fuel pressure regulator or the injectors, which can affect performance under load.
Test Drive Task: Turn the steering wheel lock-to-lock while stationary. | Note: Listen for any whine from the power steering pump; these units can show signs of wear in higher-mileage examples, so it's a good area to inspect for fluid leaks.
Test Drive Task: Inspect the area under the engine and transmission. | Note: Check for oil seepage from the main seals or oil cooler gaskets, as these are common areas where minor weeping might occur as the vehicle ages.
Consider a full cooling system flush and inspection of the auxiliary belt tensioner.
Often a good time to check the DPF (Diesel Particulate Filter) differential pressure and assess the condition of the turbocharger hoses for potential leaks.
Generally the point where suspension bushings and shock absorbers may require a refresh to maintain that signature Mercedes ride quality.
Ensure the oil service is strictly adhered to using the correct Mercedes-approved low-ash engine oil.
Periodically check the sliding door tracks and rollers for smooth operation and apply a light lubricant.
Keep an eye on the cabin air filter to ensure the HVAC system remains clear and effective.
Regularly monitor the brake fluid levels and ensure the moisture content is tested during annual services.
Keep the battery terminals clean and tight, as modern Sprinter electronics are quite sensitive to voltage fluctuations.
Estimated repair costs if issues arise
If the van has spent much of its life on short, urban trips, the DPF may eventually require professional cleaning or replacement. Future Budget Planning: It is wise to keep a reserve for this maintenance.
The OM651 engine uses piezo injectors which can eventually reach the end of their service life. If the vehicle begins to run unevenly, you might eventually need to budget for professional testing or replacement of one or more units.
Depending on the load the van has carried, the front suspension components can wear down. For your Future Budget Planning, considering a refresh of the control arm bushings and ball joints will ensure it handles correctly on NZ roads.
