Noises

[jeremyjp74]

New to the 2019 Dodge Ram 2500 (Cummins) . I’ve noticed when I shut off engine I hear a series of solenoid sounds after the truck shuts off. I also just noticed a longer sounding noise(more like a screech) about a minute after the truck shuts off . Anyone have ideas of what this could be ?

Egr valve cycling, DEF lines purging, grill shutters cycling. All sorts of gizmos on these new rigs.
