Mine looked a lot like that when I took it off after 50,000 miles. All kinds of oil residue and carbon build-up from the EGR. I just covered the electrical connections and sprayed it out with carb & choke cleaner. It blasted all that nasty stuff out of there. Gave it a quick wipe down and re-installed. Car seemed to run a little better. (Or maybe it was my imagination)

That is normal. Spray some snorkel cleaner in there, and use a toothbrush to clean it off. Too much of that residue build up will cause a rough idle. Definately nothing to worry about.
