Purpose: Enables Lane Assist for vehicles equipped with the Sign Assist and/or Light Assist options.
The vehicle must be equipped with the 3Q0 or 2Q0 camera (different A5 coding)
Caution!! There are 12 lines (3Q0) or 16 lines (2Q0) of coding to be done here.
After programming, the error “Steering C10AC F2 – Lane Keeping Assist Interface Not Programmed” may appear in A5. Clear the error, restart the MIB, then turn off the ignition and lock the vehicle for more than 2 minutes. Lane Assist should then function normally.
Procedure:
1– Engine off, ignition off, connect your official VAG-COM VCDS cable to
the computer, then plug the other end into your vehicle’s diagnostics socket.
2– Switch on the ignition and run the VCDS program.
