So i have an 2013 Audi A3 8v and i would like to retrofit the raim amd lights sensor. I currently have AUTO climate control so i do have the humidity sensor and ive heard that i just need to swap the sensors and install the lights switch with the AUTO option. I would also like to have the CH/LH lights. Im a newbie in coding so can someone please provide me with the coding to make it all work. I have OBDeleven so i cant use VCDS. Thank you
