citroen c3 ecu blocked please help

Postby Nico » Fri Feb 28, 2020 2:28 pm

we bought 2 citroens c3. 1 was stripped and the other in an accident
we start to build the parts over in the engine compartment but not the BSI
the unit did not start. we later changed almost everything , PSF fuse box, BSI , transponder coil + key. unit did not start.
we checked the system with a delphi OBD to found the ECU locked , i think it was because the bsi and the ECU did not match.
now need a 4 pin code to unlock it.
can someone help. the agent was not very help full.

the vin number is VF7FCNFUC26632725
some software number 9649811380
software version 33
index 2

ECU ref 506971
if someone can help please.

thanks for reply.
the ECU is the original that did start. bosch 7.4.4
the bsi and key is original.
I think the bsi got locked when we built the unit over from the 1 vehicle to the other. we did not swop the bsi from the beginning. but it is swopped now. the ECU , BSI, PSF fuse box and transponder all these are swopped now.
Delphi now say the ECU is locked. I can enter the code on Delphi.

I found a program that says it can get the code from the dump file. and for this reason I need the dump file or can I get the code some other way.
hope that you can assist
thanks.
