Immobiliser 4
Convenience electrics
The immobiliser 4 technology is used in the
Audi A6 ’05.
This means that all components must be "taught"
online, as is already the case with the Audi A8 ´03
and the Audi A3 ´04.
The following components are integrated into the
immobiliser:
– The control unit for access and
start authorisation
– The engine control unit
– The vehicle keys
