Good evening! I am writing this as I ran into an issue with switching out my 2019 Audi A3 (premium plus) steering wheel (without paddles) to a 2018 A3 S line (flat bottom steering wheel with paddles). The paddle shifts were not working, along with the reduced display button (view). My original wheel does have the navigation button, although it is not installed and supported on my current model. I was wondering why it was not "plug and play," as the seller stated. Is there some sort of coding that needs to be done to have the paddle shifts along the display buttons work? Any help is appreciated, as I was really looking forward to having a steering wheel with paddle shifters. Thank you!
