First I started getting these....
P20EE - SCR NOx Catalyst Efficiency Below Threshold
Then I got this code....
P2BA9 - NOx Exceedence - Insufficient Reagent Quality
Soon after that I got a message on the EVIC "Incorrect DEF detected - See dealer." I got this on every startup for maybe 50 miles of operation. This is when I posted my experience on the forum. I added 2.5 gal of fresh DEF.
Then I got the "won't start in 200 miles" message. I added an additional 1.5 gal of fresh DEF which topped off the tank. The no start in xxx warning persisted for another 30 miles and 4 restarts then finally cleared in its own, presumably when good DEF was detected.
