Auto lights retrofit 2017

[sanmark]

Hi everyone, I am trying to retrofit Auto lights and rain sensor to my A3 2017.
I have managed to find appropriate sensor, part number 8U0955559C.
My question is does someone know what is the part number for the switch?
I have found multiple switches with auto function, but there is like 6 or 7 variants, with last letters being different..

it will depend on whether you have front fog lights, automatic headlight adjusters etc.

I have all weather lights in front and xenons, rear regular fogs..

I suspect this is what you need but i dont have access to post 2016 wiring to see if there are any changes.

Thanks for your answer. Do you know whats the difference between 8K0941531AR and 8K0941531AE ??

8k0 is for a4/a5, you need 8v0.

AE only goes up to 8/16 so i believe it will have the red illumination and the fog light buttons are a different design to the AR which is the facelift with white illumination.
