New to me 2015 GSW throwing codes

So after a blissful week of ownership my new girl threw a code twice now. Has cleared itself both times, but I wanted some opinions on what might be to root cause. Here is the fault info from VSDS

The car is under the factory warranty and then the CPO warranty after that. From what I can gather from the boards this is may spell the end of the egr installed. Any thoughts?
