Hi, this is created to lock you to get access to the ecm of your car, you need a special
token to get access ,see you tube for instruction video what to do for getting access.
SFD is German for secure gateway (SGW) SFD(schutz fahrzeug diagnose)

Hi, to unlock sfd in vw you need to have a device capable of doing this there is one I
know of , its called obd 11, see you tube for instruction video and how to use it.
