I have had this issue since Christmas with error code P20DB. Related to DEF system. Happened when it was -30C. Anyone have any solutions or ideas as to how I can fix this or make it go away other then clear code whenever I go out. No one in my area wants to touch my truck or have any solutions to my problem. Also, their High Tech readers will not allow access to cpu or log issues and details.. Internet has lots of ideas but no simple fix. Any help would be greatly appreciated. Nearest dealer is an hour away. Rather not take to dealer as I have tune. In the boonies with no help!!! M
