How I fixed the roof noise on my 2012 BMW E93 330i

In this video, I tackle the annoying clunking noise coming from the center roof connection in my 2012 E93. After trying various fixes, including adjusting the front locking mechanism and checking the roll hoop and rear interior, I finally found a solution.
By removing the center locking mechanism pins, adding a 0.05mm brass shim between the bushing and sleeve, and reassembling everything, I eliminated the noise for good.
This video walks you through the process and offers insight into how the mechanism works. Please note: this is just what worked for me, and I take no responsibility if you try it and something goes wrong.
