After firmware or maps update when you start scanning your vehicle with VCDS you might see error codes:

  • 03623 – Invalid Security
  • 03276 – Please check software version management

And after US -> EU conversion you might see this error:

  • 03677 – Missing Security/Release Code on 5F Information Electr

And as you probably noticed you can’t remove it via VCDS – that’s permanent error. To remove first error you will need to apply this SCRIPT (click here).
