Anyone can helps?

When I put my dpf off, dtc goes off, all ok, but servicer told me, car works ok and suddenly in iddle to much white smoke, and after that again all ok, no smoke...
I did simply 01-->>00 switch dpf
Is it problem because of that or need some beter dpf off file?
If someone has other solution please make good dpf off

Thanks
