Hello. I’m a new member here. 2020 Ram Ecodiesel. I have them 2 codes popped up at the same time. Truck was sitting at dealers lot for couple weeks before I got it and they had to replace crank seal on it. Left dealer yesterday and then 2 popped up. I noticed that coolant is little low in reservoir but I have full heat and warms up to middle of the gauge (normal). DEF shows about 3/4. Anything I should be looking for before I take it back to the dealer? TIA
