Driving home recently near dusk, I notice that the lights (in automatic mode) had just come on. At the same time, I notice that the green fog light indicator had come on at the same time.
Wait a minute... This is a 135i, it doesn't have fog lights!
I flipped the headlamp switch from auto to off then on, then back to auto. The fog light indicator shut off, and hasn't come on since.
Anything strange and unexplained happen in your car?
