2015 TDI Adblue / Reductant Heater problems
I got these CEL codes:
P20B9 Reductant Heater A Control Circuit/Open - OBD-Codes ...
P148B Adblue heater fault
I assume this fix would be covered but my Diesel Gate Warranty.
My battery also drained. I tested the #1 fuse “Reductant Heater Control Module” and it was pulling 6 or 7 amps with the ignition off.
I pulled the fuse above to stop the battery drain, which I assume disables the Adblue / Reductant Heater.
Will pulling this fuse cause a problem if it is not freezing outside? I do intend to take it to the dealer to fix, but not today.
