2.2L (OM651) - CDI 2.0/2.2 BlueEFFICIENCY
Diesel
Check the transmission responsiveness by accelerating smoothly from a standstill. | Note: The 5-speed and 7-speed automatics in these models can occasionally exhibit hesitant shifting, which might indicate the need for a fluid flush or solenoid check.
Listen carefully for any hissing or clicking sounds while idling with the bonnet open. | Note: The OM651 engine injectors can develop seals leaks (often called 'black death'); catching this early can prevent more extensive engine block cleaning.
Operate all electrical sliding doors and climate control zones multiple times. | Note: Electrical gremlins are common in aging W639s; ensuring the door sensors and rear HVAC blowers are functional saves significant troubleshooting time later.
Test the suspension over a series of speed bumps or uneven road patches. | Note: Rear air suspension bags, if fitted, are prone to perishing over time, so ensure the vehicle maintains a level stance and the compressor isn't running constantly.
Usually the time to inspect the condition of the turbocharger hoses and intercooler for oil weeping.
Consider a proactive look at the timing chain tensioner and auxiliary belt pulleys.
A standard point to audit the DPF (Diesel Particulate Filter) soot levels and transmission fluid health.
Ensure the oil has been changed at strict 10,000km-15,000km intervals using high-quality synthetic lubricants.
Verify that the transmission fluid has been serviced at least once in the last 80,000km.
Check the coolant hoses for any signs of brittleness or swelling, as these are getting to an age where rubber components can fatigue.
Regularly clean the drain scuttles beneath the windscreen to prevent water ingress into the cabin electronics.
Keep the fuel filter fresh to protect the sensitive high-pressure common rail fuel system.
Estimated repair costs if issues arise
If the vehicle has spent significant time in city traffic, the DPF may eventually reach its ash capacity. Future Budget Planning: You might need to set aside funds for a professional chemical clean or replacement.
If your Viano is equipped with the factory air-ride system, the rubber bladders can develop pinhole leaks as they age. Future Budget Planning: It is wise to keep a buffer in case one side begins to lose pressure overnight.
The 'black death' issue refers to copper washer failure on the injectors. Future Budget Planning: If you smell diesel fumes in the cabin or see carbon buildup, addressing this promptly prevents damage to the cylinder head.
