Hello, as the title says I hear a strange returning noise coming from the engine. I believe it comes from the left side of the engine bay (when standing in front of it). Car idles normal, drives normal too, just this noise, sounds like bad news. I attached a video where you can hear it, towards the end of the video. Anyone has an idea what this possibly could be? Sounds very expensive
Thanks a lot
Ps: don't know how to attach the video, anyone?
