1.6L dCi (R9M) - Twin Turbo Diesel
Diesel
During the test drive, listen closely for a 'hissing' sound under load. This can indicate a potential split in the turbo intercooler hoses, which are known to wear over time in the 1.6 dCi setup.
Before starting the engine, check the oil dipstick for any signs of milky residue. On the twin-turbo variant, it is worth monitoring the oil cooler seals to ensure coolant and oil remain separate.
While accelerating gently, observe if the gear changes feel notchy or hesitant. The manual gearboxes in these vans appreciate regular oil changes, so sluggish shifting may suggest the transmission fluid is due for a refresh.
While parked, cycle through all electrical switches, including the heater blower and rear wiper. The Renault Trafic III wiring looms in the door hinges can sometimes face fatigue, so ensuring all power windows and central locking function correctly is a wise step.
Consider a full coolant flush and inspect the auxiliary belt tensioner for any signs of wear.
This is a good point to have a specialist inspect the DPF (Diesel Particulate Filter) pressure sensors to ensure the exhaust system is regenerating effectively.
At this stage, it is advisable to look at the health of the clutch assembly, especially if the van has spent much of its life performing stop-start city driving.
Stick to a strict oil change interval of every 10,000 to 15,000km using the manufacturer-specified low-ash engine oil to protect the sensitive DPF system.
Keep an eye on the coolant levels; keeping the cooling system in top condition helps protect the twin-turbo unit from heat-related stress.
Ensure the air filter is replaced on schedule, as a clean intake is vital for the efficiency of the twin-turbocharger setup.
Regularly lubricate the sliding door runners with a silicone-based spray to keep them moving smoothly and prevent premature wear on the door handles.
Keep a record of your fuel filter changes, as these engines are quite sensitive to fuel quality and moisture.
Estimated repair costs if issues arise
If you notice a loss of power or a hissing sound, you might eventually need to budget for new intercooler piping. It is a common maintenance task that helps restore your boost pressure and fuel efficiency.
Depending on the car's driving history, you might eventually need to budget for a professional DPF clean if the van has primarily been used for short, city trips.
If this component needs attention in the future, the estimated cost in NZ includes both the clutch plate and the flywheel, which are usually replaced together to ensure smooth power delivery.
