Seatbelt flapping in the wind
 

Hi everyone,
In my '12 GLI the passenger seatbelt flaps against the inside B-pillar when driving with the windows down. The flapping comes and goes frequently and happens at different speeds. The sound is very loud and extremely annoying. It hits the pillar below the point of where the buckle hangs. Does this happen to anyone else? Has anyone figured out an easy fix?
