Hey all,
Trying to Immo-off my wife's daily - 2002 Jetta 2.0, since the megamos chip in the cluster fried.

What I've done so far:
Built a bench harness, and I am able to successfully read and write the 95040 in boot mode.
Modified the file using eepromtool_04
Confirmed successful write of the modified file.
Reinstalled ECU and cleared DTCs.

Car still starts and dies immediately, and throws code 17978 - 35-00 "Engine Start Blocked by Immobilizer"
What am I missing here?
Does the 2.0 use a different address for Immo on/off flags?
Comparing the two files in a hex editor, it looks like eepromtool modifies more than just the Immo flag locations.
Do I need to edit it manually instead?
Attached are the original 95040 and modified version (which I read form the eeprom to confirm a successful write.)
Thank you for any help you can provide.

The original EPROM dump of your control unit is intended for cars sold in the USA, without a factory immobilizer.

This is easy to determine by obvious signs - the 04 value instead in place of the immobilizer byte
and the characters XXXXXXXXXXXXXX instead of the VIN number.
