DEF heater went bad

My parents have a 2015 F-250 6.7. Check engine came on, so they took it to the dealer for a checkup. It needed a new DEF heater installed (in the tank maybe?) and came to $1025 total. Dad is again talking about how nice the 7.3 sounds lol.

Anyone else have or hear of this issue?

had the same issue 3 years ago on my 2015. The dealer wanted 800 to fix back then so I put that money towards a weight loss program...

I also had that happen on a '15 - replaced the DEF heater. Then moved to the broken wire between the cab and box and actually fixed the problem.

The heater is fine, you need new batteries.

I had the same situation in late 2019 and the code disappeared once I installed new batteries.

Wasn’t there a service action on the DEF heater on the last generation? I seem to remember having to take my 2012 in for that.
