Mercedes a140 p0600

hello dearest members
i have a mercedes a140 1.4 gasoline siemens MAF ecu msm 1.3 with error P0600 Can bus com in ecu
-immo has no errors
-key turns, starter does not spin
-using fvdi i went to Adaptation, Reset coding. now car starts perfect but fan is always spinning and i get P0602 Module programming error.
-Probably missing flash info, if i flash a new ori file maybe it will work but it will change immo info as well,,
any solutions to this? is immo off possible?

really appreciate any input

No immo off for this. Universal emulator can do this, but I think you repair immo sync, when you used fvdi. So your problem could eventually solve star diagnosis, or something another. P0600 I'm not sure is about flash. I think such coding data in eeprom is not good. Look more carefully there. Cheers.
