Filled my def tank up about a ‘month ago but the gauge seems to be stuck on full. It hasn’t moved in a month. I know it’s used sole but it isn’t showing. Anyone have any suggestions on how to get the gauge working again without taking it to the shop once again
I recently had to take my truck in to the shop because my DEF liquid crystallized in my tank and caused at check engine light. What do I need to do to not have me DEF liquid crystallize
