Mercedes Sprinter Delphi CRD3P_B0 issue

[auto techniek]

I ve a Mercedes sprinter with ecu Delphi CRD3P_B0.

Tried to do DPF off on bench with autotuner

Car no start. Put back full backup but still no start.

Any help is welcome

try to rewrite the injectors, if the car starts, send me the file and I will make a properly tested dpfoff, hopefully there will be no problems with the writing
