I have a 2015 even before I went to the new gauge mine would do @232-237 mile left, and maybe @5-12 mile before going to 236 left ect, now it sits at and I mean full tank to the brim. Says @197-204 and sits for @25-32 miles before the counter on miles left starts to count down. Any way to reset this? Also I do have the flush black mounts too and between gauging fuel empty/.25/.50/.75/full on both their almost same the flush mount goes off a bit later but 7 LEDs verses 8 sections on gauge itself. How does one reset the main gauge to show accuracy counting down miles left?
