How to unlock SFD protected ECUs with iOS?
To keep SFD unlocking simple, OBDeleven has an SFD auto-unlock option that makes SFD protection almost invisible. If SFD auto-unlock is enabled and you try to change the Long Encoding, Adjustments or One-Click Apps in a locked ECU, OBDeleven will automatically ask for the SFD token from the Volkswagen servers, unlock the ECU, and save the value you want to change. You will need a PRO or ULTIMATE plan to be able to do this.

Follow the instructions on how to unlock SFD:

Connect to a vehicle and open the list of ECUs by tapping:

Choose the required ECU. Normally you will see more ECUs in the list, for this example we will use the Gateway ECU.

  • OBDeleven can automatically detect that the ECU is locked by SFD if you go to Long Coding, Adjustments, or are using One-Click Apps and are trying to write data but the ECU is still locked. In this situation, the application will ask you for authorization for the SFD unlock procedure.

  • Follow the steps by tapping on “UNLOCK”

  • To continue, confirm your email address (if you haven’t already), enable Two-Factor Authentication, and update your account information.

  • Proceed by tapping:
