I have set daytime running lights to be on, which when in auto mode and in the day, should be daytime running lights (the non-xenon) and then when it gets dark enough, should kick the xenon's on - my problem is that it kicks the xenons on in the morning (brigh sun) and if i turn the ignition off and then on (or park for a few minutes at starbucks), it returns to normal (i.e., daytimes come on during day not xenons) - let the car sit long enough, the problem reappears.

Any help with this mystery?!

thanks,

You are not alone...
As you describe, If you park inside the lights come on but don't turn off after exiting the garage. This is a known problem and I think some software version may have improved but not eliminated the issue.

shame...I of course was used to the lights coming on in the garage in the 04 530 i just traded in, but they faithfully went off when i pulled out into the light - anyone out there know what upgrade i should be asking for? since the build date of the car is July 13, 2005, seems odd that it doesn't have the latest software...do upgrades come that frequently?

thanks,

Had the same problem.What are your auto headlamps set at ? Nornal-Sensitive or Very Senistive.I had the dealer reset them at Very Sensitive and it helped them some what. Good luck

Vern, thanks much - I didn't know there were settings - but one question, wouldn't "more sensitive" mean the lights would come on quicker? If so, maybe the problem is that they are set to more sensitive and if backed off to normal they won't come on (or stay one once out of the garage). Any other experiences out there? Apart from the setting, is there a software issue?

thanks,

No, "more sensitive" means its more sensitive to light, so will stay off longer, and go off quiker

E60SPEED has the right answer.The only thing I noticed is when I back out of the garage and the Auto Headlights are on when you travel on a street that has a lot of trees and you are constantly going from sun light to shade and back and forth the head lights stay on until you get into a area that is all sun light for a period of time then they go out.This is normal.Hope this helps.

My 545i is in the shop right now, and the X3 loaner I am driving right now has the same problem.

Adjusting the sensitivity (dealer only) will not cure the problem. I am on 16.1 CIP now and it still have this problem. I have noticed that if you pass through a street with successive trees will permanently turn on your lights. The on-off effect (sun-shade) may make the sensor to think that your wipers must be on, indicating a foul weather. Thus the lights become permanent. This is pure speculation though.
