Connect the junction and reinstall dashboard. Remove to step 2.

 

Connect vvdi2 with laptop. Make sure network connection is enabled.
Run VVDI2 software

Select Key Learning-> MQB platform immobilizer->Dashboard- MQB48 VDO/JCI-NEC35xx LOCK

Vvdi Prog Read Vag Mqb Immo Data 21
Select Decrypt IMMO Data
Upload MQB data just read by vvdi prog

VVDI2 will decrypt immo data online, calculating online in process.

Save decrypted immo data

Now you can add key with the immo data.

For all keys lost, contact 3rd party to get sync data as well.
