[fab]

okay , I found out that for siemens ecu flash read is enough, so @fab i first need to flash virgin file to ecu and after that the off file ? is this right solution ?

And for EDC16 I know ,I need to desolder EEPROM , but what program  to use for IMMO OFF , or should i post here ?

Hi,
I do not think the immo off file will work as for this ecu its ONLY virgin...(C3 1.4 HDI 2004 = Siemens Sid802).
You will need to have your flash virginized and you need the pin (read carefully the first post in the link )

if you want to use an emulator: Page 15

For edc1634 eeprom (95160) i enough for immo off, as ROD-BENDERS said (but this is not your car...)
