As of 2020, VAG applied the SFD procedure in order to provide Vehicle Diagnostic Protection. Security Access protection system is used on 2020+ VW Golf VIII, Audi A3 8Y, Skoda Octavia A8, Seat Leon MK4 and others. Here we will show how to unlock VAG SFD gateway with our VXDIAG VCX SE 6154 and ODIS service software without login account.

It appears to generate one-time SFD unlock tokens for this exact scenario. They operate on a “credits” system, but you can buy 25 credits for 25€, (about $27) and 5 credits gets you an SFD challenge response for one module, whereas 15 credits gets you unlimited offline challenges for 60 minutes for a specific VIN.

They also offer an online coding generator for 10 credits.  You sign up/sign in and buy tokens.
