Another Check Engine light.
SCR tank heater module. $2140 from the Dealer. My Indy didn't want to do the repair. Guess he is either in over his head or just doesn't like me. This diesel is a rolling error code. Would probably trade the stupid thing if I could get the check engine light to go off long enough.

Check with a different dealer. I read about a similar thing where not the whole module was replaced, but only the heating element.
It's the heating element that heats the addblue, isn't it?
