Had this code appear after 22,000 miles on 2020 6.7 with no issues. Rather than take to the dealer I cleared the code and topped of the Def. Ran through a couple of regens and check engine light came back on after about 300 miles. Has anyone experienced this, should I be concerned. Engine...
My 2012 F-150 Platinum had an electric trailer brake controller on the drivers consul. Towing a horse trailer with electric brakes this weekend in a huge snow storm and wondering if the Tremors all come set up with trailer brake controllers? Haven't seen one in my F-350 Platinum.
How many miles are those of you with 6.7's getting when DEF gauge reads full? Mine seems to jump all over. Initially 4000 miles and now 1900 when filled. Seems to drop 400-500 miles when only traveling 100 miles. Weird!
