I did some testing this am and it seems that only 0x062 - 0x065 needt to be FF or 00 and its disabled. Also, odds are its a switch like you said. Vag cars have a have 2 bit switches to disable immo. The odds thing is I can't believe it doesn't set a code for not updating checksums.

Hi, do you know what package you have to buy with PCMflash to download eeprom from the VZ ecu ?

The process was simple, BDM read EEPROM with KTAG, write Julespatch's IMMO off file from MHHauto, job done.

Having looked deep into this it appears that PCMflash can read the EEPROM via OBD, that will be the way I do this next time.

No sorry, I don't. This thread was for E77, not E55 like in VZ.
