[335xiDriver]

So I have looked through a lot of posts talking about clutch noises but nothing that seems to match what I am experiencing. There is a squeaking noise when I release my clutch but only happens when rolling from a stop. Never happens once I'm moving on any clutch actuation. To me it sounds like a belt squeal and not the clutch itself. Anybody experience this or have some ideas?
I am going to be doing some more work on my car soon and would like to address it.
