So , question is now , what is the problem ? Mechanical ? or Electrical ?
Mechanical problem i can't help you - maybe ticket to plane will do
Electric problem - i can provide all kinds off software and ECU's for iveco. Maybe second hand ECU is broken as well. I have no id how to help you remotly . First i would to try check mechanic chain , then maybe replace ECU, but before check harnes and pins. Maybe pins in ecu harnes are not in good shape.
