Fog light coding question

Hello does anyone know what to code to have the fog lights automatically come on when the headlights are on?

Not the high beams because I know that is illegal.

I like the extra light on the sides while driving and it would be much more convenient if they came on automatically.

The 03 and 01 are Werte Values?

What is the difference the two values?

Can this coding be done without a computer? Anyone in RI/MA area care to help me just get my car coded so the fog light doesn't appear on turns?

No. A computer is needed to make the coding.

nice coding, I'll bookmark this page.
Does "small light" mean that all sidelights/parking lights are on?

Is it possible to code the DRL to stay off until the parking lights (small lights?) are turned on and dim again when switching to lowbeam or turning off the ignition?
I like to observe stars and don't want to tape the headlights when leaving earlier from a meeting

I know i'm posting in an ancient thread, but this seems like the most relevant one I've come across.

I coded the following:
MAPPING_NEBELSCHW_L_FUNCTION = 04
MAPPING_NEBELSCHW_R_FUNCTION = 04
so that the fog lights come on with the DRL angel eyes. During the day when my low beams are off (headlamp switch in auto position), it works just like i want - only the fog lights and angel eyes are on.

However, when it gets dark and the auto headlamps turn on, the fog lights turn off.

I realize if i code the values to 03, then the fog lights will come on with the automatic headlights, but then I wont get the angel eyes + fog lights only during the day.

Is there a way I can get best of both worlds? Basically I want fog lights on all the time.

If you want the fogs to ONLY come on when the fog lights do, then you would change the values for the two lines to be equal to 05. Refer to Takkey's 2nd post in this thread, he breaks down the values that would correspond to the different lights.

However, if you want to prevent the normal behavior of the fog lights shutting off when you flip the high beams on - you would code the following:

I'm commenting in here so I can come back to the thread. So Is or isn't it possible to have the fogs automatically come on with the low beams?

Not true, if you code the following:
MAPPING_NEBELSCHW_L_FUNCTION = 03
MAPPING_NEBELSCHW_R_FUNCTION = 03
the fog lights will come on with the low beams.

Basically what those lines are doing is telling the computer to treat the fog lights not as fog lights anymore, but as a different light function, denoted by a number as outlined in Takkey's post.

So if you instead set those values to 0C, the fog lights would only come on when you hit the brakes, lol!

Like i mentioned in a previous post, i have mine set to 04, so my fog lights come on with the angel eyes, however they do not stay on when the low beams turn on, even though the angel eyes are still on.

Someone's gotta have the answer out there right?

The problem is that when low-beams are switched on, the angel-eyes turn off and the parking-lights are switched on in their place (the same but with low intensity). That's why the fogs turn off when low-beams switch on.
If you want the fogs to stay on with parking lights, low-beams and high-beams, then code with option 01. However, they will not be on with angel eyes.
Note that in any option the fogs switch will not work, except if the code is 08.

Thats a great explanation, thanks XC!

Is there a different coding section that can force the fog lights on, all the time?
