cotroen c3 ECU locked needs code please.

by **Nico** » Fri Feb 28, 2020 8:55 am

hi guys
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.

Use a matched ECU & BSI and post eeprom dump from that BSI
also DON'T spam all over this forum, stick to ONE thread!!

the program I found will recover the pin from the ECU dump file. if I use a different ECU file will the pin be correct

No, you will need matched ECU & BSI, then get pin from BSI by reading eeprom

the ECU and BSI does match, it was from the same car. it is on this system that I can see that the ECU is locked

Why is it not matched? find the matching BSI & ECU for your car then get PIN from BSI and add key, simple!

thanks for the reply
these units match and the ignition switch key is also matching.
the problem is the ecu is locked and i need to unlock it with a 4 pin code. and I am looking for some one that can generate the code , if possible.

Post eeprom dump from BSI, then I will give you your PIN
