    Default Help RD4N1M-01 Vin and checksum

    Hi

    I have a PSARCD442-30 (RD4N1M-01) from a CITROEN c4 which is bleeping due to wrong Vin in dump. I have posted a dump of the 24C64 eeprom, can someone change the vin to the one in this post and correct checksum if needed.

    New Vin = VF7LC9HXC74509640

    Thanks
