Mine is a 2013 and I changed the CCV filter on it when needed, but not the EGR (even though the dealer said it was required). This is what I read on Geno's Garage regarding the EGR cleaning for 2013+ trucks:
Looking closely at their Owner's Manuals reveals that a CCV filter change is also required at 67,500 miles, However, the cleaning of the EGR valve and EGR cooler is not a requirement. We asked the folks at Cummins and they responded that you may wish to include the cleaning, but it is typically not needed until the second crankcase vent filter change. They did suggest an inspection of the EGR valve. "Sooty/dusty is good, shellac/crusty needs to be cleaned." If the valve is shellac/crusty, don't skimp, go ahead and do the entire EGR system cleaning
