2.8L (VM Motori CRD) - Turbo Diesel
Diesel
While driving at highway speeds, listen for any 'hunting' or surging in the transmission, as the 5-speed automatic in these models can sometimes show signs of wear in the torque converter clutch.
Opening the bonnet while the engine is running and observing the belt tensioner; in these diesel units, a wobbling tensioner can indicate that the bearing is nearing the end of its service life.
Before turning the engine on, inspect the EGR valve area for signs of oil or soot residue, as build-up here is common in the 2.8L VM Motori engine and may eventually cause a restricted airflow light.
Testing the 4WD selector through its full range while at a slow crawl on a loose surface, ensuring the transfer case engages smoothly without any excessive grinding or refusal to shift.
Time to verify the timing belt has been replaced, as this is critical for the long-term health of the VM Motori diesel engine.
Consider a full cooling system flush and inspection of the radiator hoses, as rubber components start to become brittle at this stage.
A sensible point to have the suspension bushings and ball joints professionally inspected, as the heavy diesel engine places significant load on the front end.
Ensure the oil filter housing is inspected for leaks, as the oil cooler/filter housing unit can be a common source of weeping.
Keep a close eye on the battery voltage; these Wranglers are sensitive to power dips, which can trigger ghost warning lights on the dashboard.
Stick to high-quality synthetic engine oils that meet the specific manufacturer specs for the VM Motori CRD to keep the DPF system happy.
Periodically clear out debris from the cabin air intake area under the cowl to prevent water ingress into the cabin.
Regularly treat the door hinges and latches with a high-quality lubricant to prevent the paint-bubbling and corrosion issues common in the NZ climate.
Estimated repair costs if issues arise
Future Budget Planning: Because the 2.8L diesel uses a timing belt rather than a chain, you'll need to budget for this replacement every 100,000km to ensure the engine runs reliably.
Future Budget Planning: Depending on how the car has been driven previously, the DPF might eventually need a professional forced regeneration or cleaning if it has been used primarily for short city trips.
Future Budget Planning: The weight of the Wrangler platform often means that after several years of NZ road use, you might eventually need to budget for new shocks or bushings to restore that solid handling feel.
