So, yesterday it took close to 2 hours before monitor showed the DEF had warmed up. Needed to add some today. Thought about keeping the jug in the cab with me until it warmed up, but figured the warm stuff would help things thaw out sooner. I wasn't working it for more than about 20 min and there it was, DEF abnormality, 59 minutes until the next warning. Still wasn't showing warm after an hour, so then moved on to level 2. Constant beep and 59 minutes until engine derate. Ran about 10 minutes and finally the indicator showed blue, but still code. Shut it off for a few minutes, restarted, still code. Was in the process of calling the shop when it finally went away. I guess it didn't like a nice hot drink in the morning like we do.
