my truck has been to 3 different dealers for a total of 6x in 4yrs for this issue.
each time its "fixed" they guarantee it wont do it again. i know once or twice the def heater has been replaced, not sure what that has to do with it. and the rest they reset it manually with a tech 2. its very frustrating!
