Error code help

[dieselguy1980@gmail.com]

I have a 2014 BMW 650i Vert Msport. Recently I noticed a small stutter during idle. Wishield washer stopped working, and I also noticed my LED lights sometimes turn with steering and sometimes don’t…was also thinking this was part of the error codes. I have no experience with BMW BUS or the electronic management side of the car. I looked up error codes but have no idea where to find bus to check for short circuit to even begin. So any advice and help would be greatly appreciated. Thanks in advance!🙏🙏
