This is usually informational. Address it at your convenience.
What the Lane Departure Warning Light Means on a Audi Q8 e-tron
On the Audi Q8 e-tron, this light indicates the lane-keeping/departure system is on, off, or unable to see the road. Bad weather, a dirty windscreen, or faded road markings often disable it temporarily.
How Urgent Is the Lane Departure Warning Light?
In terms of priority, treat this as a low concern on your Audi Q8 e-tron. The single most useful thing you can observe is whether the Lane Departure Warning Light is steady or blinking: a steady light generally allows a careful drive to a safe location or a workshop, whereas a flashing light signals an active fault that can cause damage if you continue. Pay attention to changes in how the Audi Q8 e-tron drives, sounds, or smells, since those symptoms sharpen the diagnosis considerably.
