Your request

SFD option

If your scan tool reports SFD generation 2 (newer MQB Evo / MEB), choose SFD2. Older platforms are usually SFD.

Does not cover SFD2: SFD tokens never unlock SFD2-protected modules. If your scan tool reports SFD generation 2, you need an SFD2 unlock token — not this product. Go to SFD2 product

We accept spaces, dashes, lowercase — we normalize it for you.

Tip: upload a screenshot or photo of the QR shown by your scan tool — we decode the offline challenge for you.

How it works

From locked module to unlocked vehicle in four steps.

The same flow whether you’re on the lift with a workshop tool or working remotely with an apprentice on the phone.

  1. Step 01

    Identify the module

    Note the 2-digit hex address — e.g. 17 for the instrument cluster — and whether your tool reports SFD or SFD2.

  2. Step 02

    Read the offline challenge

    Trigger SFD → ‘offline challenge’ in your scan tool. Copy the full hex string.

  3. Step 03

    Calculate in the panel

    Tap Calculate, sign in, spend one prepaid credit (buy a single token or a pack under Credits). SFD returns in seconds.

  4. Step 04

    Write to the ECU

    Paste the token back into your tool (or use our desktop app) — module unlocked, ready to code.

What you need before starting

A standard workshop kit is enough — no proprietary credentials or dealer logins required.

  • A diagnostic tool

    VCDS, ODIS, OBDeleven, autel, Launch, or any J2534 PassThru tool that can talk UDS to the target ECU.

  • Physical access to the vehicle

    We’re cryptographic, not magic — your tool has to be plugged into the OBD-II port to read the challenge and write the response.

  • A sfdcode account + credits

    Buy a single SFD token (€15) or a volume pack in the member panel. Card and crypto via Stripe / NOWPayments.

  • About 30 seconds (SFD)

    SFD generation is automatic after you Calculate in the panel. SFD2 is currently out of stock.

Where to find the offline challenge

The offline challenge is a hex blob — every tool calls it something slightly different.

Here’s how to surface it in the three most common workshop tools. Other tools follow the same pattern: SFD → offline challenge → copy hex.

VCDS (HEX-V2)

Open the target module → Security Access → SFD → ‘Generate offline challenge’. Copy the full hex blob from the bottom pane.

Module → Security Access → SFD → Generate offline challenge

ODIS Service

Open the diagnostic session → Security Access (0x29) → request seed → export challenge. Make sure you’re in offline mode.

Diagnose → Security Access (0x29) → Export challenge

OBDeleven Pro

Tap the module → Online coding → Unlock SFD → Generate request. The challenge is shown on screen — long-press to copy.

Module → Online coding → Unlock SFD → Generate request
