i bought a 02 A6, its a great car aside from when i turn on the headlights the rear passanger window goes down, happens evertime and its only that window. anyone have an idea what’s causing this?
MINE DOES THE SAME SHIT!
Definitely odd
Clean your tracks and electrical connections if that doesn’t work.
Probable the actuator itself.
Just my guess GL!
Sounds like a possible bad comfort control module.
got in the car yesterday and the problem is gone. I drove it around all day and its not doing it anymore, fixed its self
