Purpose: Enables Audi Lane Assist (on vehicles equipped with Pre-Sense).
Active Lane Assist can only be programmed to “always on” if a steering column switch has not been retrofitted.
Deactivation via the MMI is not possible in this case. If you want 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 reactivated.
If Lane Assist does not work after activation and there are errors with the A5 camera, see the important information at the end of the tutorial.
Warning! There are 6 lines of coding to do here.

IMPORTANT INFORMATION:
If, after activating Lane Assist, you receive “steering” and/or “data bus” errors along with a “Lane Assist unavailable” message on the MMI screen, perform an “AutoScan” and clear all diagnostic trouble codes (DTCs) for the entire vehicle. Wait a few moments beyond the two-second time required to clear the codes, then exit VCDS. Turn off the ignition, exit the vehicle, and lock it for at least 6 minutes. Follow this procedure exactly.
