Hi guys. I just got an e36. It's almost 30 years old and just as many issues. If you look at the video you'll see the lights flashing. This happens when i turn the steering wheel. It has a new battery and alrernator. Kinda stuck atm with no idea where to look for the issue. And couldn't find other related posts or similar issues anywhere. The obc also does the same thing with the lights. Any ideas? Thanks Snapchat-658575966.mp4
