DUCATO DPL Regeneration

Hello colleagues, has anyone had problems with 2.3 euro V duchato, in reference to the multi-particle filter, accusing the P1206 Error code and P2002, it does not start regenenação dPL or leaves vigor to regenaração through the scanner, already changed the sensor the catalyst pressure a little time, which had paid off, but now again it does not make the regeneration, tomorrow I will see if the new sensor will see if the new sensor will burns, someone with the same problem? I was spoiled with a gun, could anyone use the Diagum launch to regenerate some duchato or boxer? Any help is welcome!
