Had this before,it turned out to be a fractured fuse that was not obvious to the naked eye, it was on n/s under the big plastic cover as suggested and also controlled the breather heater down by the turbo,maybe check for a feed to that might give you an idea whats going on. Also had a sprinter CDI no com turned out to be ECU hope this helps
