Probably the easiest way would be to use a diesel fuel additive that states that it removes injector/cylinder deposits. It will have a detergent/solvent in it that will soften up carbonous deposits. Put some in a chemical resistant spray bottle and with the engine at the lowest possible idle spray the fuel additive directly into the intake manifold. Give it a good soaking and then shut it off, let set for a while and give the solvent in the fuel additive to do it's job.
You might try calling your local Ford auto dealership. Back when I worked for ford in the late 90's they still had a foaming upper cylinder solvent. It was sprayed into the intake system until the engine stalled and left to set for a half hour or so and then started. It worked great on gas carbon deposits and don't see why it wouldn't work in a diesel. The major benefit of this product is that the foam expands to completly fill the cylinder and back side of exhaust valves which means it stands a better chance of completly coating the deposits. If they still sell it it would be worth a shot.
