Thank you phobic,
Yestoday, a senior seller employee found out the reason.
Glass adhesive between windshield and A-pillar was cracked.
Replace windshield and glass adhesive, the issue has been resolved.

I have a 2013 135is with the exact same issue of popping sound described in this thread. Did anyone ever figure out what was causing the problem. Sometimes it sounds like it is coming from the outside, and other times the inside. Seems to most happen when the A/C is on but I did have it happen one time without the A/C. Any help would be greatly appreciated.
