    Inside ECU shoud be 93CS46 EEPROM (maybe with Bosch marking: B58323 or something like that).

    Read this EEPROM and post dump.

    Hi
    the best method to deactivate immo for this kind is :
    1- remove eeprom from ECU or put it all with FF "93CS46 or 24C"
    2- do not connect the key pad
    Immo is broken, car start normally
    Ps: Don't connect the key pad forever otherwise the immo will be reactivated
    Thks !

    the 8 leg eeprom is the one nearest the centre of ecu, remove and fill with FF write as 8 bit, unplug keypad and refit ecu - now no immo.
