Actually, you do not have to pay much for security code to Opel. It may cost approx. 20 $.
Seems you have Immo1. I'm almost sure, the eeprom in it will be closed for reading.
Please send me log - I'll tell you exactly. If yes - the program will not work to read the code, sorry.
You have 2 way - order the code to Opel or read the eeprom from Motorola microcontroller by yourself.
