Hi all,

I have a 2016 F36 Gran Coupe. Lately, I have noticed a very strange loose screw sound behind the B-pillar. It almost sounds like a loose marble that rolls back and forth upon acceleration and deceleration. I have checked all the HVAC vents under the front seats and it appears empty. The sound is driving me crazy. The car is still under warranty and I was thinking of taking it to the dealer for a investigation and hopefully a fix. I was wondering if any of you have had a similar experience? Any thoughts, suggestions, or ideas would be appreciated. Thank you!

The B Column is very easy to remove.
