M4 Paddle Shifter Issues
I just purchased a new to me 2018 M4 Comp with a bunch of M Performance options that were included at build/dealer installed.
Running into issues with the paddle shifters, I get random issues with the following. These are very intermittent. - Sometimes paddle shifters sometimes don't work at all in either drive mode or sport mode. Pulling either one does nothing in either mode. - Sometimes the upshift paddle shifter works, but the downshift paddle shifter also executes an upshift. - The shifter stick always works regardless of drive modes. - It has a dealer installed M Performance Electronic Steering wheel. Does anyone know what could be the issue / common issues before I bring it into a BMW dealership. I've searched around and all I see are grounding issues and faulty connector issues leading to shift lights not working well. Video of one of the issues: |

probably a bad connection in the wheel when they installed the electric one.

That steering wheel is not the stock steering wheel, it is an M Performance steering wheel. Whoever installed that wheel must have messed something up with the paddle shifters when the new wheel was installed.
If the car was purchased from a BMW dealer I'd take it back to the dealer and have them fix it. If it was purchased anywhere else, you may have to take it to a BMW dealer or an independent and have them fix it, or attempt a DIY repair.

Quick Question where you able to fix the problem? I have a 2016 M3 Comp that just started doing the same thing which I thought was rather weird.. Any insight you can give will be greatly appreciated!

The clockspring was at fault, they replaced the clockspring and everything started working again. |

It could definitely be an issue with the clock spring (slip rings) that allows data to be passed from the rotating steering wheel side to the stationary steering column side. However, because the stock wheel has been replaced, there could have been installation issues.
Did it do these things as soon as you purchased the car or was it after a certain amount of time and/or mileage? |
