VCTool fully supports the SFD protection system used on the MQB2020 (MQB37W) platform used by Audi A3 8Y, VW Golf VIII, Skoda Octavia A8, Seat Leon MK4 and others.

The application allows you to receive unlock requests from control units, unlock control units using tokens both manually, when the user generates a token upon request, and send an unlock request using the SFD VCTool unlock service.



VCTool ECU menu

1 If the control unit supports SFD, you will see an “SFD Manager” menu item in the left menu of Gateway coding list, or the SFD button in the coding / adaptation editor instead of a line for entering a login.

If, during the activation of hidden functions, VСTool detects a locked control unit – a message about the need to unlock will appear in the function check window and a button with a lock icon will appear to start SFD Manager directly from the function activator window.

2 To receive an SFD request from the control unit, select the type of request and press the Send Request button. In most cases, the “Online Unlock Request” request type is required to generate an offline token.
