Great news!! The AFL on my new Mokka works perfectly now! On collecting my car this evening I was informed that the Valet sticker had been placed on the inside of the windscreen, directly in front of the camera. It was obscured by the rear view mirror, so we didn't see it. So information going to the computer was... It's pitch black outside = High beam.
Oh it was heaven driving home and no one flash me. I'm am now seriously happy with my car, it is a dream to drive.
