    surely a simple 'search' for the bytes in your favourite hex editor will locate it?

    Thank you Dodor , Filutek and others,
    just tested this, use address 3FD0-3FD2 of flash file , double adress 3FD1 > in my example FC 37 18 becomes FC 37 37 18 - then XOR this value with crypted eeprom location 10-13 or 50-53 (in my example CE 0E 0F 28) and you will get the pin code in hex 32 39 38 30 which is 2980 in ascii , read in reverse > 0892 this is your pin..... By the way, IO terminal with Multitool and Opel bsi license will do this in seconds…..

    thank you very much, just tested your calculator, works 100% !

    you might consider adding the HW Key Number which is visible in ASCII at eeprom address 502-50B (uncrypted) , System Name on address 5634-563A in flash, Software Number on address 563C-5640 in flash and System Description on address 3F8E-3F96 in flash but that info is not really important like your key or pin info.....

    thanks again for your work !
