I have this sound that is really annoying, and it does not sound right. I can’t figure out where it comes from, but its only there when the engine is on. This is an 730D from 2003. I have a link to a YouTube video that i posted. Heres the link https://m.youtube.com/watch?v=7ueY63WZfro
Hope someone can help me understand what it is, and if its bad or normal.
Thanks
