I am new to Eco Diesels. I just got a 2015 Ram 1500 Eco diesel with 188K on the clock, that looked like it rolled right out of the show room, I got a decent deal. I have had a few CEL event, all the p20ee. A week ago I though it might be a good time to add some DEF, I was close to 1/4 tank, added some fresh DEF and then got a CEL, p2BA9 and then a p20ee. I thought like the p20ee, the p2BA9 was a fluke, I added fresh DEF and so reagent quality was not an issue. Then I started to get the "Engine will not restart, go see the Dealer" screen. I read somewhere that I should have just driven the truck at 50mph until it cleared the code. I didnt know that ten. I also read that if you remove 2.5+ gals of DEF from the tank and then refill with a few gallons (a few step in between) this will have the effect of restarting the p2AB9 process. I removed 2-3 gals of DEF only to see that the DEF gauge hardly moved, it has moved a little since, but not to where I thought it should be. Do I need to find a dealer or shop that has a wiTECH computer? Is there anon-dealer solution to fix this problem? Can AlfaOBD help me fix this problem? Any help would be greatly appreciated.
