Diesel particulate filters and power reduction?

Hey friends, wanted to go to the city this morning and take a ride with my fat guy. Anyway, after about 3 minutes when I started the error message came that the DPF filter is full and that I should read the manual. I did everything as it was in the book and I also drove 80km and while driving the light bulb flashed, suddenly the car also slightly accelerated as if the turbo was without function. When I felt the error after the (regernations) ride After another 3 minutes the same error came again, plus luminous engine control light. I also did not drive short distances a week ago I came out of the holiday and drove back and forth 1300km. My question would also be whether the emergency run is a problem of my own or whether it is related to the filter, unfortunately I don’t have much idea of cars myself. Also, I don’t know what else to do besides nurturing the thing, cleaning it out or having it emptied out and coded out. W I would be very grateful if someone had other suggestions and could help!
