Where do you go to enable the Foglights. Thank you in advance for the help.

Where do you go to enable the Foglights. Thank you in advance for the help. pott2300: Hello. That's a very good question, but it is posed with an economy of information!!
Which fog lights (front, or rear) are you referring-to? Does your car have the fittings physically installed? Do you have a rotary light switch with the commensurate fog position? What version of control module (the one at address hex09 which OBD11 calls "central electrics") does your car have- because this determines whether (or not) the "fog light" pins are installed on the module?

I apologize for the lack of info. It is the front foglights. I have installed all the needed hardware. I have a USA spec 2016 GSW. I am just trying to go into the computer and see if I can activate them or if I need a new BCM.

The two Leuchte channels that control the front fog-lights are:
•(Left-side) Leuchte12NL LB45
•(Right-side) Leuchte13NL RB5
If you have been able to run the new wiring to the control module, then I assume that the PINS on pin #45, socket B and pin #5, socket B were actually there (i.e. the male pins were physically on the control module). This is a good sign that your control module is capable of operating the fog-lights.
Assuming that you have installed LED style fittings and assuming that your new loom connects to the 2 x pins above - try this:
Leuchte12NL LB45
Lasttyp 12 > 6 - LED Lichtmodul
Lampendefektbitposition 12 > 38
Fehlerort mittleres Byte DTC-DFCC 12 > 22
Lichtfunktion A 12 > Nebellicht links
Lichtfunktion B 12 > not active
Dimmwert AB 12 > 127
Lichtansteuerung HD AB 12 > Always
Leuchte13NL RB5
Lasttyp 13 > 6 - LED Lichtmodul
Lampendefektbitposition 13 > 42
Fehlerort mittleres Byte DTC-DFCC 13 > 23
Lichtfunktion A 13 > Nebellicht rechts
Lichtfunktion B 13 > not active
Dimmwert AB 13 > 127
Lichtansteuerung HD AB 13 > Always

PS: here's the wiring arrangement for the fog lights (both front and tails) - note: BCM (or, J519) is the control module that OBD11 calls "central electrics"

No it didn't work. I am confused because if you look at the instructions people post on how to enable this thru vcds it says you have to tell the system there is a light switch with front fogs installed. Is there something I am missing here. Thank you

Is there something I am missing here. Thank you pott2300: You are entirely correct - I had forgotten the instructions that are required for telling the BCM that you had installed a light-switch that contains the front fog-light position. My apology - my only excuse is the ravages of old age and an over-fondness for single malt scotch (both of which have destroyed millions of brain-cells that I can ill afford to lose)!!
Somehow I have just acquired the status of Moderator - I have no idea how this happened. However, whilst I'm humbled by the honour, I suspect the elevation is greatly exaggerated (as the omission in my response to you clearly demonstrates)!
Request to Admin: can I have my old rating as rookie "New Member" back - please?
Don
Anyhow - here's what I should have added in my 1st response (note: I've shown the long-coding solution below, but you can achieve the same outcome by setting Bit 3 in Byte 7 using OBD11's short-coding method):
Note: the 3rd screen shows "LDS_mit_Nebellicht" (Light Switch with (front) Fog Lights) as YES because this screen is from my car. Your screen should have the setting No - which needs to be changed to YES as per the 4th screen.

I don't think the Golf tsi models come with led foglights. Unlike the GTI models.

Ok, please show me the coding for ft and rear fog light switches. I'm doing the same but, also planning to have rear led fog active too. Just order a new switch.

Sorry to resurrect an old thread, but i was looking for this information exactly. I purchased a Golf TDI S with a GTI bumper and installed the wiring and fog light switch. I followed these instructions exactly. In live data it shows the fog lights being activated when the switch is pulled. No lights work though. Either both lights are dead or my coding is incorrect? I plan to pull the connectors and put a test light on them but was wondering if there is something I did wrong or if there was a different seetting? I only want the fog lights to come on when i pull the switch.

^^^^hmm........ did you install incandescent, or LED fog-lights? If the latter, is the polarity correct - meaning are the earth and active wires swapped?

sorry, I did not realize I had a response. I checked all the coding again and it matches the info earlier in this thread. The wiring was a simple harness and had pre installed connectors. Not sure it could have been any easier. Pins were installed in headlight wire harness as well as BCM. I must be missing something. The indicator light on the switch comes on when its pulled out. When i was trying to code it previously, i did get an error message on the car to check left fog lamp, so this tells me its getting power? I also kept seeing that Byte 7 Bit 3 had to be checked and i cant seem to get to that. I only get Byte 0,1,2.

ammonut426 : The problem with tweak instructions on forums is that often folk believe that MQB platform Golfs are ALL the same - alas they are not!! I suspect that the problem here is that the 09 module in this car does NOT have an active long-code string. In about mid 2016 (depending on the country of sale) - VW made a major change to the coding database in the 09 module. The new 09 modules from that time had no long-code facility and ALL of the software switches that were previously in long-code were transferred to adaptation channels. This had the effect of making an already big adaptation channel count in the 09 module even larger! So do this:
- Ignition-ON and Engine-OFF
- Fire-up OBD11 software and connect to dongle
- Select central electrics module from the Control Units screen
- Scroll-down and select Adaptation
- Enter "ueber" into search box and select Außenlicht_uebergreifend
- Scroll-down and select LDS_mit_Nebellicht
- Change setting to YES and follow the prompts to implement the modification
- Exit OBD11 software and cycle ignition

EDIT: I finally got to take a picture with my phone up into the B connector and apparently i dont have the pins on the BCM.
I get to the search point under adaptations and there are no results. I scrolled through and also noticed its not listed. Another site mentioned my car may not have the correct BCM, but when I was playing around before I was able to get an error message so I think I have the ability with this BCM? I followed an old post of yours for changing the headlight setting to recognize the switch with fog light option and was hoping that was it, it wasn't.

That can be done even without changing the BCM, I actually did it on my car with the help of Don.
you need to find all the unused light related pins in your BCM (you can check all the Leuchte channels for ones that aren't coded) and see which ones aren't occupied but are physically there.
In my case i used pins 10 and 21 in socket B, they are the largest i could find that were unused, then you code them just like you would be coding the original pins (5 and 45).
