Anyone else in the cold zone having this issue?

My Low DEF came on and the heater element code at the same time.
I put 2.5gl into the passive tank then few weeks later when i got the BMW bottle i also put that in. Few days later my light went off and its been a week, no stored codes or anything. Knock on wood.
