Why are my lights always on?
 
Lights on auto mode and 3pm in SoCal on a cloudless day and the xenons are on? Where is the light sensor? Just seems silly. Anyone else having this happen to them?

Can you check the IDrive, go to settings and cancel the daytime running light option? How are you ejoying the truck?

Yep, I've turned of the daytime running light halo's -- was referring to the the full xenons as if it were night (green light is on on the instrument cluster) which seem to always be on because the sensor seems overly sensitive.

It's a known issue. For some reason the Auto Light system sees a clear blue sky as being dark - even though it clearly isn't - and brings the lights on. If there are clouds, then no problem. My 2005 E53 has done this since day 1 and even though the dealer reduced the sensitivity of the system, it still happens to me and a lot of other Owners with Auto Lights. The Dealer in the UK said they were aware of it, but there was no fix and it wasn't a fault.

There's a comment in the MY2010 E70/E71 Owners Manual on Page 102 of the on-line version which applies in low sun, but I get it anytime in the later afternoon. I don't know what part of the spectrum the sensor is looking at, but clear skies are an issue, cloudy or part cloudy not.

I expect to have the same issue with my 2011 E71 xDrive40d when it arrives next week.

Interesting - we have allot of blue skies here, haven't had such a problem yet. Did the truck's sensor get replaced / recoded or did you leave as is?

Cheers,

I'm in socal and have the exact same issue. I was just too lazy to post about it. Good to hear it's somewhat normal. I'm not gonna worry about it. lol.

Maybe something is blocking the sensor?
