It's rare to hear of a clogged EGR on a newer diesel with DEF and DPF. But on 10 year old systems, it's common.
There were early rumours that the 6.7 Cummins in the new RAM HD (2020?) would eliminate the EGR completely. But lately I've been reading that it will still be there.
That's what they keep saying, but here is my truck at 29K miles with a new turbo, EGR, EGR valve, waste gate and solenoid, but look at the EGR cooler core. This truck is rarely driven except when it has the Montana hooked to it. The core should be pristine. No codes or other problems. Just a hauler.
That EGR cooler looks normal and all the paths are clear for exhaust flow, so you could say it's pristine for a EGR cooler.
My truck has 840 idle hours and probably looks similar or maybe even worse. Ford designed the EGR cooler with replaceable cores for a reason.
