Hey guys so I have a strange high pitch fluttery noise coming from the back part of my engine compartment and can't seem to pinpoint what it is. The noise occurs during cold start and is really loud! It also occurs whenever accelerating but only randomly. Sometimes it doesn't. I'm guessing it has something to do with the turbo since it sounds like more of a pressure leak. Could be a pcv issue as well. Any ideas or suggestions help. I'm going to link a video shortly
