veki, this is the steps to take.
Activation of second rear fog.
I have a 2017 SE-L Estate RHD UK spec, with LED headlights and NON LED rear lights.
I found that only the right hand fog light came on but on checking established that there was a bulb fitted in the left hand cluster and could see it was not an LED through the lens.
I followed the initial steps to activate but nothing happened.
Then I found the key to the change that would activate it.
Controller 09 - Central Electronics
16 - Security Access - enter 31347
10 - Adaptations
Then look at both of the following settings to establish what the differences are.
Leuchte26NSL LA72
Leuchte27NSL RC6
When viewing either of the above there are 3 values that will be different:
LASTTYP which will be the top value
LICHTFUNKTION either A26 or A27
and
DIMMWERT AB26 or AB27
Whichever has the values in is the active lamp.
You need to make a note of them and make the other the same
The main one is the LASTTYP.
That indicates the type of lamp you have fitted. Right down the value as you will be looking for the same lamp on the other side.
All of the adaptations have suggested "32 allgemeine LED bis 12W"
This is a type of lamp and may not be the same as yours.
Once you select LASTTYP you will see a long list of different lamp types.
Select the one that matches the lamp you already have.
Then change
Both LICHTFUNKTION A26 and A27 to Nebelschlusslicht wenn kein Anhaenger gesteckt
and
DIMMWERT either AB26 or AB27 which ever is the setting that is on 0 to match the other value. I found it to be 100.
Hope this helps.
