I exposed a problem with a Vito 108 2.2 CDI and nobody responds or does not know. The problem is already solving Professional, I hope someone is able to get a little closer to this problem, which giving a small track (it is usually a logical failure in these electronic injection systems)
Hello, if k read your problem but ... your problem is a car that is in your workshop and I suppose it should be fixed faster than we take to answer aki.
When I read the first idea that came to my mind is that the injection ramp loses the pressure and after insisting the pump again load it.
So a boat soon accusing the pump pressure valve.
Eye: I have not had the opportunity to repair any CDI.
