Predict my agony
2021 RAM Cummins with 57k miles. Just got a check engine light. Says "See Dealer for DEF Service". How painful will this be? I assume this could be anything from a DEF injector to and SCR or DPF problem. I'm doubting DPF because I usually drive 60 miles per day when I use it on the highway with little or no idling. Also haul a decent sized RV with it.
Bringing it to the dealer in the AM. We'll see.
