Hello Pit,
The last version that works with self-built interfaces (e.g., our B1 kit) is our manually unlockable 409.1, which is also continuously maintained (label files,
Autoscan, plugins where possible).

In order for VAG-COM 409.1 to function with a custom-built adapter, the adapter must meet certain criteria in its transmission characteristics. Therefore, only VAG-COM 311.2 can be used with optocouplers without significant effort.
Starting with version 504.1, VAG-COM always queries the license data within the diagnostic system, and manual activation is no longer possible. Therefore, VAG-COM (VCDS) version 504.1 and later only works with our semi-professional and professional systems.
