Itchy

Hello. I don't what to do anymore, I have MY2008 Octavia II. My radio volume control on MFSW is not working. My MFSW have Telephone buttons on left and up, down and volume on right. Can someone take a look at my autoscan and tell me where the error could be? Or what to check next? According to what I have read everywhere, these components should be functional after proper coding. Which I also don't know if it's 100% correct. Physically, the buttons on the steering wheel work for me if I hold the side button on the right stick, it switches maxidot with any button which is weird. I don't know if it's related to that, but I can't get to the maxidot menu by holding down the button on the right stick either. I also don't know what was originally on the car and what is being retrofitted. Can someone take a look at my autoscan and tell me where the error could be? Or what to check next? Autoscan aktual.txt
