It says my DEF tank is empty (yet it is full) and is limiting me to 55 mph. Is there anyway to 'fix' this with the tuner other than just deleting?

(This is a new issue and I have not had time to research it thoroughly due to work and a family illness. Any help will be greatly appreciated)

attempting to tune 'broken' parts is usually a recipe for disaster.


with that said you could turn it all 'off' and unplug it if you live and drive outside the USofA.
