Auto headlights won't turn off

I have a 2010 Octavia FL.

I have all 10 wires coming from the headlight switch to the BCU and have rain sensors and light sensors for the mirror, so in theory I have everything for auto headlight right?

I swapped the switch to a genuine one with auto feature, and when I set it to "Auto", the headlight just stays on.

It's a pretty sunny day and it just stays on. Every other setting works correctly, but the "Auto".

Do I need coding? If so then where do I need to go in VCDS?

Thanks!
