What is SFD?
Vehicle Diagnostic Protection (also known as SFD – Schutz Fahrzeug Diagnose) is an additional security layer that requires authorization between the vehicle and manufacturer.
It’s been introduced by Volkswagen Group (VAG) to help protect vehicle owners from fraud by providing information on who and when has made modifications to their vehicles. SFD restricts functions like adaptations, coding, and parametrizations.
This protection applies to the models manufactured from 2020 with the MQB Evo (e.g., VW Golf 8, Škoda Octavia IV, Seat Leon IV, Audi A3 8Y, Q4) and MEB (e.g., VW ID.3, ID.4, Škoda Enyaq) platforms.
The control units protected by SFD include Engine Electronics, Central Electrics, Instrument Cluster, Gateway Electrics, Multimedia Unit, and more.
