Good morning all,

We’re attempting to activate the rear fog lights on our 23 F54 JCW with bimmercode and are running into an issue with the coding. I purchased the new switch assembly which has the correct buttons, I am able to activate the switch (with 3068) so that the rear fog icon shows on the digital display.

When I code the output and function, the switch with turning on and off the rear Union Jack lights instead. I have confirmed the rear fogs have bulbs and are operating (then on when rear doors are open).

Below is the code we’re using, which should work for almost all F56 and F54.

Activate Rear Fog Lights feature for lighting switch:
3064 Mapping_Nebelschlussl_L_output = nsl_l
3064 Mapping_Nebelschlussl_L_Function = nebelschlusslicht
3064 Mapping_Nebelschlussl_R_output = nsl_r
3064 Mapping_Nebelschlussl_R_Function = Nebelschlusslicht

Has anyone else ran into this issue? Thanks!

 

After-market UJ lights?

 

No, they’re factory UJ lights.

 

In F54 LCI the lights on bumper is not fog lights.


You can do some tests.

try to code this

3064 Mapping_Nebelschlussl_L_output = sl_l
3064 Mapping_Nebelschlussl_R_output = sl_r
Mapping_Nebelschlussl_L_FIXED= pwm
Mapping_Nebelschlussl_R_FIXED= pwm
Mapping_Nebelschlussl_L_PWM_1_STANDARD = 13.7V
Mapping_Nebelschlussl_R_PWM_1_STANDARD = 13.7V

 

I went in and checked the values, neither output allows “sl_r or sl_l”. FIXED and PWM values were already what you provided.

The options available for output are either “nsl_l” or “rfs_l”, which I’ve figured out the rfs is the reverse lights, and the switch can control those if coded that way.

since it’s an LCI2, do you know if maybe the 0x00 values under output may need to be different? I’m unsure what those numbers mean.

thanks!

 

sl_l=0x14
sl_r=0x15

 

That fixed it! Working as it should now. I truly appreciate it!

 

could you take a picture or movie to show it?

 

Absolutely, here you go:

 

What about the brake lights??
They're supposed to be on the bumper.

Did you recode the tail lights on the barn doors to work as brake lights??

 

Think they just need recoded to be the brake lights on the barn doors.

 

The brake lights are already on the doors with the 2023s. My initial problem was the original coding was switching the entire door assemblies on/off.

 

Hiya..
Thank you for the info, but I would like to clarify as I seem to have got it to work but having another interesting issue.
I'm in a 2022 Clubman S ALL4
Are you saying to put those into the mapping_nebelschlussl R&L? under custom value? I did this and it worked fine. (I am using bimmercode)

The interesting issue im having is the actual light switch is remaining illuminated at all times now even in the daylight outside.
Have you come across this or did i make a mistake somewhere?
Much appreciated for your help.

 

Just did this and to follow up for future.
EU lights have the fog in the UJ door lights
USA lights are missing the LEDs to do this.
BUT you can code the rear fog lights to the bumper lights.
NSL_L - do a custom value of 0x14 for left bumper light
NSL_R - do a custom value of 0x15 for right bumper light

I took the Porsche approach and only activated the left bumper light as my rear fog.
