Activate rear right reverse light

I have verified the following on my 2019 SE: Channel 09 (Central Electronics) Adaptation
Leuchte 0 -> Left front turn signal
Leuchte 1 -> Right front turn signal
Leuchte 4 -> Left front DRL
Leuchte 5 -> Right front DRL
Leuchte 6 -> Left front lo beam
Leuchte 7 -> Right front lo beam
Leuchte 8 -> Left front hi beam
Leuchte 9 -> Right front hi beam
Leuchte 16 -> Left rear side light
Leuchte 17 -> Right rear side light
Leuchte 20 -> Left rear outer light
Leuchte 21 -> Right rear outer light
Leuchte 23 -> Left rear inner light
Leuchte 24 -> Right rear inner light
Leuchte 25 -> Rear tag light
Leuchte 26 -> Front side lights (both sides)
Leuchte 28 -> Left backup light
Leuchte 29 -> Right backup light

That second red light that turns on on the driver side is a fog light. They installed an inner tail that contains a rear fog light and coded the car to tell the control unit a rear fog is present and a Euro Switch has two pulls outward to engage. First pull is your front fog, second pull enables the rear fog.

Here’s the coding:

Rear Fog Light

Select: 09 - Cent. Elect

Select: Security Access -16

Enter the Access Code: 31347, then “Do it!”

Select: Adaptation - 10

Search: Außenlicht_uebergreifend-LDS_mit_Nebel_Schlusslicht

Select: New Value "Yes", then click “Do it!” (This tells the BCM that a light switch with rear fog function is installed, Euro Switch)

Search: Leuchte28RFL LC11-Lichtfunktion A28
Old Value: Rueckfahrlicht
Select: New Value "Nebelschlusslicht wenn kein Anhaenger gesteckt", then click “Do it!” (This tells the BCM that the vehicle is to use a rear fog in that lamp position, formerly the reverse light.)

Here’s mine NAR model after swapping out the inner tail unit. We don’t have the corner reverse lights in the U.S. like ROW models, ours are non functioning blanks. So in my config I lose the reverse light on the driver side on the inner tail. The rear fog also turns on in reverse but it’s red, not white like on the passenger side. Do this here in the states and if the tech doesn’t know it drives them insane. Told my advisor to tell the tech this is by design. Tech still determined to “fix it” by reflashing my 09 Central Electric module clearing all my previous mods 🤦‍♂️. That’s why you take notes and document your changes.
