Title: EEPROM data and vin nys inspection
Post by: _nameless on July 30, 2016, 05:42:32 AM
Up to now I've never had a issue with cars passing inspection with a blank or non matching vin. Recently I've had this issue occur. Problem is immo3 EEPROM with blank or mismatched vin will fail only immo3 EEPROM tho. I did a narrowband to wideband conversion on a 2000 mk4 1.8t used a awp Ecu, flash file and EEPROM with blank values and it still failed inspection even though in 2000 imm02 didn't have the vin strored in the EEPROM. Ie found 2 ways to solve this issue. Use the EEPROM from the immo2 narrowband car and immo off in flash or use immo3 EEPROM and patch the vin. I've verified both methods as working.

Can I ask how did you patch the VIN in the immo3 cluster? I have just done an immo2 to immo3 cluster swap and I would like to correct the VIN on the new cluster... I have the eeprom dump and the ability to read/write the eeprom.

immo off in flash

I know this is probably guarded info, but can you share how to do this?  :)

Did you try to use a hex editor?

Yes but I believe the VIN is stored in 3 locations in the EEPROM only one of which is in the unencrypted portion of the EEPROM. It seems the OP has a way to change all the references to the VIN so I was wondering how that is done?
