By chance is the Ford dealer a little ways away? Possibly long enough for the truck to go into regen?
What mods are done? Fill out your sig so we know what you have.
Let them replace the part then unplug/delete the EGR and delete the DPF....problem solved. You will pick up some fuel economy, Hp, have a cleaner/happier engine, and love the way the truck drives....the way is should from the factory.
