F80 Rear Fog Light Enable

Greetings all. I'm anticipating a move to the UK in the next 18 months and I'm trying to enable my rear fog lights.

Per this thread: http://www.bimmerfest.com/forums/sho...light=rear+fog

I modified the switch and did the coding, but so far only the light on the dash works. When I press the button the dash indicator light goes on and off, but nothing is happening at the tail lights. I tried it with the car running and lights on and off and nothing changed.

I went back and checked my coding and compared it to the values specified in the F30 Coding Reference Guide that came with E-sys and everything is the same.

Interestingly, under REM, 3063, mapping_nebelschlussl_L_function, nebelschlusslicht is the only option. The same is true for the right side.

I've even pulled down the rear trim from the trunk lid and confirmed I have a bulb on each side that does nothing. The rear fog bulb is contained in the same housing as the backup light, and I have wiring in place.

Ideas?

I assume you coded all of these:

FEM_BODY / 3060 LCEMaster 1C / NSL_Verbaut = Verbaut

REM / 3063 LCELampMapping 2 / Mapping_Nebelschlussl_L_output = nsl_l
REM / 3063 LCELampMapping 2 / Mapping_Nebelschlussl_L_Function = nebelschlusslicht
REM / 3063 LCELampMapping 2 / Mapping_Nebelschlussl_R_output = nsl_r
REM / 3063 LCELampMapping 2 / Mapping_Nebelschlussl_R_Function = nebelschlusslicht

You assume correctly. I even went back and re-read each module to confirm the changes were applied. When I coded both modules I didn't receive any errors, either. I have no reason to suspect it shouldn't be working, but it doesn't.

I have the light switch in the auto position and it works for me. Maybe something has changed?

I had mine in auto as well. I almost never use the regular on position. I'm going to keep thinking about what else I can try, but for now I'm out of ideas.

Success! I may have not coded the FDL after changing the REM, because all the values had reverted back to default. I reapplied them, coded FDL, and it's working now.

Thanks for the assist!
