Hey guys. I have a 2012 dd15 epa10. Def has been demandated on this truck.

For a year now this same check engine light comes on about 20 minutes after start of the truck and driving.

I checked the fault and its "Doser Fuel Line Pressure High"
Number 4077
Confirmed, active permanent

Any idea how to remove this by going into parameters?

Thanks in advance

Whoever did delete did not do it properly.

I agree with you. I would like to know if this can be fixed by changing some parameters.

no it will need to be wiped and start over with a proper file for the truck and go from there. DDDL isnt going to save you on that one.
