Zed-Full ZFHC-EA External Antenna For VAG OBD applications to calculate 7th byte of CS
125,00 د.إ
The Zed-Full ZFHC-EA External Antenna is an accessory for the IEA Zed-Full key programmer, used mainly in VAG (Volkswagen/Audi/Skoda/Seat) immobilizer OBD work.
What it actually does
Its main function is to help with Component Security (CS) handling, specifically when the system requires “7th byte CS calculation”.
In simple terms:
- VAG immobilizer systems use a CS (Component Security) code for key authentication.
- Some vehicles do not provide the full CS directly via OBD.
- Instead, part of the CS must be derived or recovered using additional procedures.
