Purpose: to activate Audi Lane Assist (for vehicles equipped with Pre-Sense).
Active Lane Assist can only be coded to “always on” without a retrofitted steering column switch.
Deactivation via MMI is then not possible. If you wish to deactivate it, you must recode the activation status.
Note: The system can be deactivated while driving by pressing the ESC (ESP) button.
However, as soon as you activate cruise control, the lane departure warning system is activated again.
Warning! There are 6 lines of coding to do here.
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.
