Hi, I am working on an 2018 Audi A3 Technik. I had to get a left new headlight. Installed it and my high and low beam doesn't work. Ordered a new motherboard for the beams, installed it and still doesn't work. I checked fuses and replaced them and nothing. Is there something that I am missing? I haven't worked on an Audi before, so not sure if there is something else I have to do in order to get it working. Called the dealership and they couldn't help me. Any help is appreciated! Thanks!
