Had something similar on a friend's F30, car didn't show any issues until a few months down the road (low idle and car stalling). Took a look at the BMS intake tubing and the hose clamp was tightened too much creating a small gap in the intake tubing. We took it off and reinstalled it properly and all the problems were gone. Key is just to tighten enough so that it is snug.
TLDR: Make sure the hose clamps are properly tightened, but also make sure they are not over tightened to the point that the intake tubing is pinched.
