P20B9 - w221
I have a P20B9 code. At first, based on threads and recommendation of a local shop, I changed the def tank heater and nozzle (xemodex) and the larger supply line (pressured) but I still get the code. Any insights what else it could be?

P20B9 OBD-II:
Reductant Heater "A" Control Circuit/Open
You choose not to disclosure your location, but if you are in US and performed AEM, you have warranty.
Still open circuit calls for checking/cleaning the plugs. Did you erase the code after parts dropping?
