Professional VAG SFD1 ECU Authorization Service for Protected Control Units
VAG SFD1 Unlock Tokens provide professional authorization access for supported Volkswagen Group control units protected by SFD security systems.
This service is designed for workshops, diagnostic specialists and professional users who require temporary authorization access for supported protected ECUs when performing coding, adaptations, service procedures and diagnostic workflows.
Each generated token is a single-use authorization token designed specifically for the ECU challenge generated from the vehicle.
What is SFD?
SFD (Schutz Fahrzeug Diagnose) is Volkswagen Group's security architecture used to restrict access to protected control modules and sensitive diagnostic workflows.
Protected control units require authorization before supported operations can be performed. SFD tokens temporarily authorize the protected ECU so supported diagnostic workflows can proceed.

How Token Generation Works
Token generation requires information generated directly from the protected control module.
- Step 1: Generate the ECU challenge using ODIS diagnostic software

Each token is generated specifically for the provided ECU challenge and is intended for a single authorization workflow.
