Thank you for the answers.
Then, remembering that I am a layman, I ask for clarification:
1 the fact that the old do not enter into the diagnosis and this provides a datum that will almost certainly exclude the possibility that the problem was of another nature? (I ask, because knowing that you're not magicians, and seers I would like to make the right choice and continue the path that I have taken, that is, not to put the unit new. However, if I solve, then I'm going to spend a lot more).
2) you say that my can you recover, but then what might be successful for having impallata while I was walking, and make inaccessible the control unit to the diagnosis?
3) at this point, assuming you have both restored what on earth?I remember the one that crashed is the model that damage now in Fiat for my.
4) can be repaired by sending it only the ecu?in case anyone here is doing it?
Thanks
