I've searched "How To's" and "Tips" - nothing comes up for egr+cleaning, clean. A lot comes up for the egr on "Troubleshooting", but the closest I've seen to what I want to know is a mention that the egr filter can become dirty or clogged. No comment on cleaning it.

Thanks for the info on paint color. That will help me with trying to match the color to touch up a couple of dings.
