For example, when my #5 fuel injector was failing, the DTC would remain but the CEL was off more than it was showing.
It didnít say. It said performance failure of some sort and it pertained to the DEF heater.

CEL came back after driving on a dirt road. Prior to this, full regen and no CEL.

It's hard to say what Ford's stance is on this failure at a given mileage. It is an electric heating element so they do get fatigued over time. Not to mention it's submerged in Urea.
Why not put the heating element OUTSIDE the tank instead of IN the caustic urea? That would even make replacement easier?

Kind of like a heat tape system for water, DWV and LP/natural gas?

That's an idea. Double layer though. Protect the heater unit from whatever crap is on the road and then there is another plastic layer to the DEF.

Yup...seems simple doesn't it? Since I don't know how the systems works, does the feed line/system need protection as well?

Even better! just make the process for replacement easy, like the heat element coud screw off like a spin on oil filter with just a simple WEATHERPROOF electrical connecter?

Urgent!

tnis may have been listed but I don't want to scroll the entire chapter.
Ford has a service bulletin on this.
Customer Satisfaction Program 18M01.
It addresses the reductant heater and sender issue. CEL and possibly a " reduced power mode"
Its good till December 31, 2018 regardless of mileage.

When they replace the heating element do they have to dump the tank?
As soon as I got my truck back the 800 mile till empty light came on.

That I do not know. Someone else may be able to comment on that. I brought mine in for a CEL today and the customer satisfaction recall. Mine was a plugged EGR cooler AGAIN.

If that question is for me...I tow VERY little. I do a lot of highway driving though.

FYI, thereís a VIN cutoff on this little deal. My VIN falls outside the coverage, but thankfully the warranty I bought covers the repair.

HDSlowride is gaining momentum as a positive member of FTE.
They replaced mine last week. Local Ford dealer. Mileage was 46469. DEF tank was full when I took it in and full when I got it back. No note of adding fluid after the remove and install reductant tank assembly. Parts and labor were all covered. No cost to me.
I had one instance a few weeks ago of a CEL and message "exhaust fluid system fault" that went out on its own an hour or two after it came on.
