VCDS CODING UPDATE
We will update the following list again and again to the best of our knowledge. Which control units are currently protected by SFD?

The previous procedure (activation using a 5-digit login code) no longer corresponds to the state of the art.įor this reason, the protection of vehicle diagnostics is to be gradually introduced into new vehicle models, starting with the VW Golf 8. The control unit checks the token using a special function on the tester and grants access after it has been successfully checkedĪccording to analyzes by VW, there is an increased need for data protection in control units. You log in to the dealer portal and enter the locally saved activation requestĪn activation token is generated that can now be entered manually in the tester The activation request from the control unit to generate the token is saved locally This is explained in note form below:ĭirect token retrieval with the diagnostic tester fails There is a so-called fallback solution should problems arise with the online method. The entire SFD process requires an online connection of the diagnostic tester! In parallel, the transition to strong authentication is being developed. In the transition phase, weak authentication should be possible at the beginning via the dealer portal using a user name and password. Google Authenticator, Microsoft Authenticator) This can be implemented, for example, by using one of the following systems:Īpps or applications that can generate one-time passwords (e.g. In addition, strong user authentication is required for better logging (2-factor authentication, or 2FA for short). This is also known as end-to-end protection. This means that changes to control units are made via a secure connection between the control unit and the vehicle manufacturer. This level builds on level 1 and also has manipulation protection for the diagnostic content. In addition, changes to control units are logged at the individual level in order to ensure traceability. Reading activities such as reading out the error memory or displaying measured value blocks (actual values) are still possible without a token. This level includes access protection for changes to control units, such as coding, adapting and parameterizing. SFD is to be introduced gradually in 2 stages, which are explained below: This token is currently only available through an official GeKo (secrecy and component protection) account, which must be requested from VW. From 2020, the VAG Group has introduced a new procedure for protecting vehicle diagnostics (SFD), starting with the VW Golf 8, which is based on the MQBevo platform.Ĭertain control units in new vehicles are then protected by SFD and can only be coded or adapted after entering a special token.
