Hey guys I'm new at BMW and i got a 2010 e92 335xi. When I got it everything in te steering wheel worked fine. Then I changed the battery and they didn't work nor did the padle shifters. Does anyone know why? I brought at BMW but they needed the car at the shop for many hrs. And for 130$ per hr it's not cheap. I was wondering of anyone know how to fix it. Should I open the steering wheel controls see if there
Is a loose wire or something?
