Right off the bat let me say that my car is xenon pre-lci so I can't confirm if this works on LCI/LED cars. Someone can test this and let me know in the comments.
Anyways, yes you read that title correctly. This is a
front "fog light" mod. It uses the front fog light button/command to increase the brightness of the angel eyes when the low beams are on. (This mod assumes you haven't already coded your angel eye brightness to 100% when your low beams are on.)
So why even do this? Because driving around with your angel eyes set to 100% when your low beams are on at night is kind of a dick thing to do. It causes a lot of glare and people may high beam you to signal their discomfort. It's happened to me multiple times and It's made me want to do something about it. You might be saying "well why not just turn your angel eye brightness down back down to the stock levels and leave it there?" Well, because sometimes I want them dim and sometimes I want them bright. This mod gives you the option of turning the angel eye brightness (when the low beams are on) up from a lower setting to a higher one without having to code your car each time. You can now literally do it with a push of a button. Big thanks to
Poochie for all the info and all his help getting me sorted.
How to do it
If you have the stock north american light controls and you want the fog buttons to illuminate you'll need part #61319265303 (pre lci cars only)
https://www.ecstuning.com/b-genuine-...319265303~oeb/
(You can find it used on ebay for a lot less if cost is an issue)
You'll want this switch because it has the illuminated rear fog button as well incase you want to code in the rear fogs:

Coding for this switch so it doesn't throw errors at the dealer:
Bimmercode:
FEM > Expert Mode > 3064
LCECONFIGURATION > LCE_BEL_LIN_VAR > BEL_FLC_NSW_NSL
Installation of a new switch is super easy, you can literally just pry the driver vent out and then pull the light switch panel out. You don't even need a pry tool you could do it by hand if you wanted to, it takes 2 seconds. Then just unplug the old switch and replace with the new one. Reinstall switch and vent and you're done.
If you already have the euro rear fog light switch because your car came like that stock, or you've already done the rear fog mod, you won't need a new switch you just have to find a front fog button off any similar 2/3/4 series light switch panel. I found one on ebay for $25 and will simply take that button off and move it to my current switch:

If you do not care for an illuminated button and want to keep your stock light switch you will need to modify the stock fog light button:
First you have to pop out your front fog button with a pry tool:
Next you shave down the 3 largest black plastic teeth.
Pop it back in and ensure it now moves back and forth when you press it.
Once you have your new switch installed or your old switch modded it's time to code:
Bimmercode:
FEM > Expert Mode >
3060lcemaster:
nsw_verbaut > verbaut
3063lcelampmapping2:
mapping_nebelschw_l_output: 0x30
mapping_nebelschw_r_output: 0x31

Enjoy
Edit:
I made this DIY a while ago and have since changed my coding so the front fog switch activates the orange side markers. DIY for that can be found here:
