Disadvantages, breakdowns and problems of OM647
The main problems of this diesel engine are related to Common Rail fuel equipment.
The reason for the airing of the system here is most often the drying of quick releases.
It is necessary to change the refractory washers after dismantling the nozzles or they will coke
Due to soot, the dampers of the variable intake manifold geometry are often wedged
In terms of electrics, the DPRV and DPKV often fail here, and the wiring of the injectors also burns out
