My wife's vehicle is a jeep grand Cherokee ecodiesel. It went into limp mode this am with an error message saying DPF is 100% full, service required.
Can I force a regen with Alpha OBD in limp mode or get the ECU out of limp mode then force it to regen ?
Thanks for any help!

first thing to know is .... why did it go to 100%
if it was just neglect and not paying attention to the previous warning the Alfa will work right away .
it could be a bad sensor as Big John had in this thread .
procedure described in the thread , you'll have to read a little , at least not the entire site ...

Filter at 100%, Forced Regen and GDE

he purchased a used crap sensor , and could not do the stationary regen ,
then have a look at
post # 102 , when he got a good sensor the stationary regen worked

There is two "force regen" in AlfaOBD:
'DPF Regeneration Enabling' performs a moving regen during next drive cycle,
'Particulate Filter Regeneration' performs a parked regen when coolant is over 140f
I have tried the first one, you actually enable it with the ignition on but the engine not running then turn the ignition back off. Wait a few minutes then start the truck and go for a drive, it will start a regen when warm enough.
Being your getting the 100% full warning, you may need to do the second one, but not sure the exact procedure. You find the regen options in the Diesel Bosch EDC17C49 module
