How to Manual Unlock VAG SFD Gateway with Xhorse?
XHORSE cannot automatically unlock the SFD gateway; it requires obtaining the calculation code from a third party.
Method:
- Obtain the vehicle SFD seed code (vehicle data) via OBD.
- Send the seed code to a third-party service for calculation manually (i.e vag logins).
- Copy the calculation result into the input field on the tablet. The SFD unlock will then be completed, with a validity period of 90 minutes after unlocking.
Go to Unlock SFD function.
Upon opening it, a QR code will appear.
Scan the QR code with your phone to obtain vehicle data on the webpage.
Send the see data to a third party for calculation.
Upload the calculation results.
The tablet will then display a “Unlock Success” notification.
After unlocking SFD gateway, you have 90 minutes to perform related functions.
Then generate dealer key and learn key with vvdi key tool plus.
