Something strange happened today. The DEF gauge has been slowing depleting and was below 1/4 full for a week or so with 1,200 or so DTE. Today when I got in the truck, it showed almost half full and the DTE was 2,500. It slowly dropped by 100 mile increments, every 5 minutes or so, until it was at 2,100 DTE.
Anyone experienced this? It has about 3,900 miles on it.
