Viano CDI 2.0L - Turbo Diesel
Diesel
Listen for transmission shudder | Description: During your test drive, gently accelerate through the gears to see if there is any hesitation or 'shuddering', which can sometimes indicate the transmission fluid or torque converter may eventually need attention.
Check the air suspension leveling | Description: Park the vehicle on level ground and check if it sits evenly. If the rear appears to 'sag' after sitting for a while, it is common in older models for the air bellows to eventually require replacement.
Operate all electric sliding doors | Description: Open and close the sliding doors repeatedly. These mechanisms are complex, and it is wise to ensure the motors and sensors operate smoothly without catching.
Monitor the dashboard for DPF warning lights | Description: Since the 2.0L CDI is a turbo-diesel, confirm there are no active warnings regarding the Diesel Particulate Filter (DPF), as these systems often require specific long-distance driving habits to stay healthy.
Time to verify the health of the turbocharger and inspect the intercooler hoses for any signs of perishing.
Often considered a stage where engine mounts may start to soften, leading to increased cabin vibration.
A common point to check the condition of the alternator and starter motor, which have worked hard over the vehicle's life.
Ensure the transmission fluid has been serviced regularly, as this is vital for smooth shifting in the W639 chassis.
Keep a close eye on the engine oil and filter changes every 10,000 to 15,000km to keep that turbo diesel running happily.
Check for any signs of surface rust around the door seals or wheel arches, as New Zealand's coastal air can be a bit harsh over time.
Regularly clean the drain holes near the windshield scuttle to prevent water ingress into the cabin electronics.
Verify that the battery is in good health, as these vans rely heavily on consistent voltage for all the integrated comfort modules.
Estimated repair costs if issues arise
If you notice the van sitting low after parking, you might eventually need to budget for new rear air springs. It is a common wear-and-tear item for high-mileage Vianos.
If you experience a loss of power under load, the turbo actuator can sometimes get tired. It is worth keeping some funds set aside just in case the turbo system requires a professional tune-up or rebuild.
Given the weight of the V-Class, the front suspension components work quite hard. You might eventually need to plan for a refresh of these bushings to keep the ride feeling as comfortable as it should.
