Michael: The module identifier tells you whether the car has SFD2 protection and you should be able to access this information without unlocking the module!
But first - SFD2 is the result of the 2 x UN documents below:
- UN Regulation No. 155 - Cyber security
- UN Regulation No. 156 - Software update
I'm not sure which diagnostic device(s) you will eventually choose - but no matter which, it will almost certainly work by reading the module identity and then selecting an ODX file which contains instructions about how to open and read the information in the module. If the identifier for the ODX file contains the term "UNECE" - then the protection protocol will be SFD2
Of course how the ODX file is disclosed will depend on the diagnostic device - but I provide the examples below for the way that VCDS & OBD11 identify the ODX file on the Gateway module for a VW ID7, which has SFD2:
- OBDeleven: ODX name = EV_GatewICAS1MEBUNECE_VWE3
- VCDS: ROD = EV_GatewICAS1MEBUNECE_VWE3.rod
So, look at the ODX file name on your chosen diagnostic device(s)

Please don't PM to ask questions about coding, or vehicle repairs. The better place to deal with these matters is on-line, in the forum proper. That way you get the benefit of the expertise of the wider forum! Thank you.
