Hi, please advise.
I bought a switch with Auto function. Can you please advise me what encoding to use with VCDS?
I have a Polo 6C 2016 Bi-xenon and rain sensor.
Thank you Mirek

Hi Everyone,
so in the end all that was needed was coding :

So here are the changes I had to make to get the RLS to work:

BCM long coding:
Byte 06, bits 1:0 - changed from 00 to 10 (enables sensor of type 'PR 8K3/8K9+8n6')
Byte 07, bit 5 - changed from 0 to 1 (enables 'Light switch with assistance driving light')
Byte 07, bit 7 - changed from 0 to 1 (enables Humidity Sensor - not really needed but why not...)
Byte 13, bit 5 - changed from 0 to 1 (enables Automatic Wipers)

Hello,
i recently installed the rain sensor, and the auto light switch.

I think you should procced with the following changes to the BCM coding.

Byte 6, bit 3 – light switch with the Auto position set to
Byte 7, bit 0 and bit 1 – the Coming/Leaving Home function is turned on
Byte 7, bit 5 – activation of the low beam control assistant
