That was my guess, this is my first bmw so idk what the average rpm climb is like... But this thing is jumpy.
So I'm guessing it has a clutch and light weight fly wheel, I just wish there was someway to tell what was in it without dropping it.
This chatter seems to be awfully loud to be natural from a lwfw, so I'm hoping there is a heat shield chatter too.
Do you think there is any chance it is a throw out bearing?
