DEF Level Indicatior Slow To Reset
Have a 2013 F-250 with an interesting DEF issue. When the level indicates under 1/2 full in message center, I have always topped it off with the Motorcraft Jug and Nozzle, so I know it is full. However, it may take the system up to 20 miles and/or several start and stop cycles to show that the tank is in the OK range. Have never let it go beyond less than 1/2 indicator. I am concerned that I may have an issue and was wondering if this is normal or not. I guess I would describe the issue as it is slow to reset as, so far, it always has after what I see as an extended period. Any ideas?
Update. My Ford Guy, who's pretty reliable says it is defective DEF Tank Sensors. Fix is to replace DEF Tank. A few weeks wait due to the fact that this is, evidentially, a wide-spread and known issue, and the tanks--unless you are down--are backordered. He also says that if you keep the DEF Tank topped off, or at the very least, refill at less that half warning, you might avoid being down until you can get it in for a fix. It WILL need fixing, however, many of the problems are related to setting the sensors off and them not resetting quickly or at all and this might keep you running until you get into the dealership.
Still welcome any ideas, though!
