The new calibration is supposed to help with the false error condition, too.
Also, if they do the recall work, the DEF is known good and the DEF injector is working, it points at a bad SCR catalyst, which is an emission system component and covered anyway.

Frankly cause I am tired of paying a dealer for crap I cannot do at home. That really irks me.
I am going to call the shop my family uses for their vehicles and see his confidence level with this car. That will happen before the tune trigger is pulled.
