i think thats the light that you can get on the A6 where there is a LED under the wing mirrors and that lights up when you unlock the car light the coming home?
no ambient illumination is red, i have those vanity mirrows and ambient illumination on my front dome lamp. just when i was coding up my warning/puddle lamps there was a option on vcds on the front door modules for ambient mirror illumination. i was just wondering if anyone knew what this was? all ambinet lighting is red as far as i know.
