2.9L TD 5-Cyl (88kW) - 4WD
Diesel
While switching between 2WD and 4WD modes on a gravel surface, ensure the dashboard indicator stops flashing and stay engaged; in models of this age, vacuum-operated hub seals may eventually require attention to ensure reliable drive engagement.
During a cold start, observe the instrument cluster for the glow plug light; if it stays on after the engine is running, it's common to consider that a glow plug or the control module may need future inspection.
While driving on an incline at moderate speeds, pay close attention to the smoothness of the automatic transmission shifts; depending on the service history, older units can sometimes benefit from a fluid and filter refresh to maintain shift quality.
When navigating over uneven surfaces or speed bumps, listen for any subtle knocking or creaking from the front end; given the vehicle's weight, it is reasonable to expect that suspension bushes or ball joints might eventually need replacement to keep the WOF standard high.
Inspect the timing chain tensioner and ensure the cooling system hoses are supple rather than brittle.
Consider a comprehensive service of the differential and transfer case fluids, and inspect the fuel injection pump for any minor seal weeping.
A deeper look at the alternator brushes and starter motor health is recommended for continued reliability.
Evaluate the condition of the radiator and water pump, as these components often reach the end of their primary lifecycle around this milestone.
Verify the age and condition of the fuel filter, as the 2.9L TD engine is particularly appreciative of clean, moisture-free diesel.
Check the condition of the vacuum lines around the engine bay, which assist with both braking and the 4WD engagement system.
Inspect the chassis for any surface corrosion, which is a proactive step common for older ladder-frame SUVs in coastal NZ environments.
Ensure the engine oil and filter have been changed every 10,000km to preserve the Mercedes-derived internal components.
Test the operation of all interior electronics, including the electric windows and mirrors, to ensure the wiring looms remain in good health.
Estimated repair costs if issues arise
If the 4WD system fails to engage due to air leaks in the hub seals, you might eventually need to budget for a seal kit or manual hub conversion to ensure off-road capability.
Depending on how much towing the vehicle has done, you may consider budgeting for new heavy-duty shocks and bushes to restore the original ride comfort and handling.
To maintain optimal fuel economy and reduce smoke under load, a future budget for professional cleaning and calibration of the mechanical injectors is a wise consideration.
If cold starting becomes labored, it's common for one or more glow plugs to require replacement; this is a standard maintenance task for older diesel engines.
