Is it unusual to have no faults whatsoever? I've run it a bunch and haven't gotten any to come up. I'll get working on some of the other data.

by the time the check engine lights comer on and the regen starts complaining, it is too late for the EGr system. There are no 'dirty sensor' faults, the ecm is too dumb for that. You just have to keep after things once a year and keep the EGR and its sensors cleaned regularly. - No repair shop is going to do this for you at all, as they are not trained to do tune-up work to keep the engine healthy.
here is some references...
