Here we have M642 Mercedes-Benz 3.0 V6 new diesel engine as complete assembly from Mercedes_Benz Germany. This engine pretty much comes with everything. Only few pieces are missing such as belt, alternator, AC compressor, power steering pump and starter. Everything else is here. As you will see it has turbo, wire harness, fuel filter, glove plug module, injectors to mention a few. It also comes refilled with oil. 

We have transferred all of the missing pieces to new engine. Programing of injectors to CDI is a must other vise there will be misfire and engine will not run correctly. Also, adaptation of air and fuel needs to be completed. Good idea to clear adaptation and let it learn new values.
