I have about 86k miles on my 2016 144 4 cylinder / OM651 and just threw a P2457 check engine light (CEL). Had the code read at Autozone. It shows EGR Cooling System Performance or something like that.
In my readings, it seems that this is common on the 6 cylinder, but not the 4 cylinder. Could be a temp sensor? Dirty EGR cooler? I cleaned an EGR cooler on a Dodge Ram before (PITA). I can't even identify an EGR cooler when I glanced under the hood on the van!
Anyone else have this?
I'm scheduled to drop it at the dealer tomorrow and hope that it's covered under warranty.
