Hi, I've changed my Audi A3 (2013 1.4 TFSI 8V) steering wheel. My issue is that my buttons aren't working. I'm just wondering, is this something I can fix or does it have to be like this? The steering wheel was changed from the Audi A3 normal steering wheel with shield air bag, and all MMI buttons (star, navigation, music up and down, phone) to the 2018 MF flat line S-Line steering wheel. Any help would be much appreciated!
