Unlocking the latest VAG SFD (Vehicle Diagnostic Protection) gateway on your Autel scanner is crucial for accessing advanced diagnostic functions. This guide provides a detailed walkthrough on how to obtain an Sfd Token Autel and successfully unlock the gateway, using a 2024 Audi Q7 and an Autel IM608 II as an example. This process applies to most Autel scanners, including the Ultra Lite, MK900BT, and MK808S.
Understanding the SFD Lock and Autel SFD Token
Volkswagen and Audi vehicles utilize the SFD gateway to protect critical diagnostic functions from unauthorized access. Before performing procedures like adaptation, basic settings, or coding, you need to unlock this gateway. This requires a unique SFD token Autel, generated based on your vehicle’s VIN and a specific request from your Autel scanner.
Step 1: Initiating the SFD Unlock Process on Your Autel Scanner
Connect your Autel scanner to the vehicle’s diagnostic port. Navigate to the Control Unit menu, select the desired system, and attempt to access Security Access (Login). The scanner will prompt you with an “SFD unlock is required” message, indicating that the gateway is locked.
The prompt will display crucial information:
- Confirmation of the SFD lock
- Remaining unlock time (if any)
- An option to “Manually unlock SFD”
Click “Manually unlock SFD.” The scanner will then generate an “Unlocking Request” containing vital information. Copy this information, including the system and VIN numbers, as you’ll need it later to obtain your SFD token Autel. You will also be prompted to enable access to Gateway (address 0019) and disable the diagnostic firewall.
Step 2: Generating the SFD Token Autel on vaglogins.com
Open a web browser and navigate to vaglogins.com.
- Login or Create an Account: If you’re a new user, create an account. Existing users can log in with their credentials.
- Purchase Credits: Navigate to the “Memberships” section and purchase credits. These credits are required to generate SFD tokens. Options typically include single-use or time-limited tokens.
- Access the SFD Generator: Go to the “SFD generator” section on the homepage.
- Enter Vehicle Information: Input the VIN number of the vehicle you’re working on. Select the desired token duration (e.g., 1-time or 60-minute). Click “Activate access.”
- Enter the Unlocking Request: Locate your VIN in the list of locked vehicles and click on it. Paste the “Login Request Info” you copied from your Autel scanner in Step 1. Enter the diagnostic address: 0019.
- Request SFD Token: Click “Request SFD.” The website will process the request and generate your SFD token Autel. Copy this token to your clipboard.
Step 3: Unlocking the SFD Gateway using the Autel SFD Token
Return to your Autel scanner and the “Manually unlock SFD” screen.
- Enter the SFD Token: Paste the SFD token Autel you copied from vaglogins.com into the provided field.
- Unlock SFD: Click “Unlock SFD.” The scanner will verify the token and unlock the gateway. You should see a confirmation message indicating a successful unlock.
The unlock typically provides a specific time window (e.g., 90 minutes) for performing diagnostic functions. After this period, you may need to obtain a new SFD token.
With the SFD gateway unlocked, you can now access restricted functions such as oil reset, service resets, and maintenance interval adjustments.
