Sounds like the fuel exhaust filter got clogged.
They truck usually cleans it from time to time.
The truck can be placed in a limited motion mode
or the programing will just stop the truck.
Usually running the truck down the road for 30 minutes to an
hour will clean out the filter. The dealer can also clean the filter
by running the engine at a high RPM for a half our.
This is what what you've described sounds like to me.
The DPF and the DEF are two completely different and independent systems. A plugged up DPF will have no effect on the DEF tank level system.
