Daylight vs Taillights

I got a 2013 5 series for my sister and I noticed that when daylight option is activated it works only for the headlights while taillights remain off!
my 2010 BMW daylight works for head and rear lights and this is a logical thing I guess since daylighting is meant to increase car presence on the road so I don't understand why BMW changed it to be a headlight only feature!
Is there a way "programming" that allow taillights to switch on when daylight is activated.

it can be coded. search through the forums here as its been mentioned before.
If you search for rear drls, you should be able to find something.
EU regs changed around Feb 2011 so the tailights were disabled with DRLS. You can code them on though. (I asked a fellow forum member to do mine)

further to this, the section you need to change in e-sys is as follows (taken from f10 cheet sheet which you can google for)

FRM 3050 DRL_Modus
all 8 values are below and you want 4 on the assumption have xenons (my Uk car had option 7 from the factory). I don't know if works teh same with non xenon cars, otehr on this forum will be able to confirm that.

0: DRL disabled; 1: DRL_H via beam, halogen U.S. (without lights); 2: DRL_L via low beam; 3: DRL_S via separate TFLeuchte; U.S. Xenon (rings +
bottom); 4: TFL_S via separate TFLeuchte; ECE Xenon (rings + bottom); 5: TFL_ECE (North Country Comfort); 6: DRL_S_ohne_SL via separate
TFLeuchte without taillight / tail lights, U.S.; 7: TFL_S_ohne_SL via separate TFLeuchte without tail light / rear light, ECE

thanks guys, still don't find a reason why BMW did that change and turn those beautiful taillights off

I believe it was to save fuel, although I really don't see that tailights are going to consume much fuel at all anyway.

How much energy is used to build the car in the first place!

Fuel and something legal I heard (from these forums). I had a Dec 2011 build and it is enabled (rears are on with DRL on)... I saw that Jan 2012 onwards had this feature disabled....

I am going to try to get my car coded later so that my rear lights are on with the DRL's

I always thought they were until I checked recently.

I got this done last night. This is how the F10 should have came. Now my beautiful tail lights are on once the car is.

Funny i always thought the car has DRL tails because my 09 335 did.

I doubt it as well. I asked my dealer and they said they coulnd't due to EU regulations.
Not usre if thats a won't or a can't,
no harm in asking though, but realistically, you'll have to have it coded.
