I have no idea where the light sensor is to see if a spider or fly died in there and is giving the sensor a false reading.

Any ideas other than take it to the dealer?

Is it possible that the lights came on when you were in the shadow behind the truck. I've noticed mine come on for a few moments when the sun is blocked, even though it's a sunny day.

I assume the logic behind is that even with the sun lowish in the sky but still bright, that for drivers driving INTO the sun may have difficulty picking out a car coming towards them if they are blinded by the sun. I've certainly been in that situation before and dipped beam will ensure that there is the contrast there and allow people driving towards you (towards the sun) that you standout.
with the sun behind you , your view may be perfectly ok (which is where the complaints might be coming from) but as I say , drivers driving towards you may have more difficulty picking you out initially.

But that is supposedly what the DRLs are for, no need for dipped beam.

Valid point

The function that BMW uses for the light sensor is somehow very complicated and it is very difficult to know when it is the time that it turns on. There are threads (Like this) that talk about it a lot. I found that in the morning or around sunset or even afternoon when you go toward sunlight it will turn it on. Think about it this way, if it is difficult for the cars coming toward you to see your daylight lights then it will be on.

How about the tail lights?

They won't be on on cars post feb11 (except possibly sweden?)
You can code them on if you wish.

I mean the tail light beening on is part of the reason BMW turn the head lights on during solar glare situations. I dont agree with it myself, I turn the auto headlights off in the day time.
