Awesome. Was it a lot of work? Where did you power it to and where did you tap power from?
I may want to do this too but I don't want the light to be too bright as it'll be on all the time.

Honestly it is not brighter than the taillights! I removed the rear wheels to have room to work and then removed the rear inner plastics in the wheel wells. I cut the factory harness thats in place for the rear fog lights then tapped them into the harness for the lights on the rear black trim. Thats the cheap way to have functioning rear fog lights. You can also wire the lights to a separate switch if you'd like but thats another task. But just a matter of running wires.

These are LED lights, and I'm wondering why there's even ICs (shown in the first page of this thread) where it shows the circuit board. So I'm thinking it's not just tap power and hook them up. Did you tap the power from and to the LED that's soldered on the board or can you just provide a 12V into the plug on the module itself and it'll light up?

The bulbs are just standard halogens. No LEDS were in mine at least. No tapping was done to the circuit board. I tapped into an existing harness for POWER and GROUND. Just a matter of tapping two wires to (one for power and one to ground it out) and you are golden.

Oh.. I see. I thought all F56 had LED lights for the rear fog light.

Mine didn't come with them but I was looking to add them in as it is an easy swap.

Nice idea, is it obvious which wires to tap or does it require a bit of digging?

As I just posted in the coding thread, you need to do the following - not just buying the switch, but also using e-sys to enable the feature in the body domain controller (BDC)




First, purchase the version of the light switch for your car that includes the rear fog switch and fit it.


Then, the following coding is required to make them work,


1) add option 5AA rear fogs to the VO (vehicle order)


then in the BDC, code the following :-


2) 3068, NSL_Verbaut = Verbaut


(This enables the BDC to sense the switch, if you just code this and try the lights, it just activates the symbol on the instrument cluster but does nothing else)




3)


3064 Mapping_Nebelschlussl_L_output = nsl_l
3064 Mapping_Nebelschlussl_L_Function = nebelschlusslicht
3064 Mapping_Nebelschlussl_R_output = nsl_l
3064 Mapping_Nebelschlussl_R_Function = nebelschlusslicht




These options enable the correct outputs on the BDC to activate the lights. You could choose to have only one light on if you wished




After doing all the above, you will have fully working rear fogs, confirming that both the wiring is already in place, and BMW rape your wallet for a $100 option that only needs probably an extra $1 in components in the switch module. They obviously have a very savvy marketing department who have figured out perceived value of such options like this that cost them next to nothing


BTW, the OP was asking about the light switch connector. It is three wires no matter what version/options you have. Power, ground, CANBUS. This is typical of multiplexed wiring used by BMW.

For my F54 Clubman, step 1 was not required. I only coded steps 2 and 3 to activate rear foglights left and right. Car has LED lighting package. Maybe newer cars don't need step 1, i don't know. I bought the light switch off eBay for 39 dollars shipped. So its cheap and easy.

I did the coding through Bimmercode app, not e-sys.

Do you have the ebay link for the light switch?

Does anyone have the instructions on how to pull the panel and remove the existing switch to install the new one prior to coding in the fogs?

Any chance you have a step by step on the coding you did through Bimmercode app?

+1 on that, the dealer is going to upgrade my software, I wanted to try Bimmercode, but don't see it in the options.

Go to Headunit. Then Expert Mode. Then Steps 2 and 3.

Found it, not in head unit.

As I mentioned earlier, its showing coding that is incorrect when reading.
For instance tire temperature with TPMS shows inactive, when is is active. I had it coded by a guy with E-Sys.
Shows DRL in unknown.
Im afraid of what else it reads wrong, and recodes it wrong. I can't look at _every_ parameter.

Sorry. You're right. It's BDC i think. I don't know why I said head unit.

Right, but what do you think of it reading my existing coding incorrectly

Anyone else notice the latest Bimmercode update no longer sees the BDC.

All I get from the developer is the same response overtime I ask a question.
It will be fixed in the next revision. HA!!

EDIT

Due to the new mandatory recode by MINI, Stephan at Bimmercode needs to rewrite his software, as MINI made it harder to access.
