I have a 2008 340. When going over waves, sounds like something loose near the port wiper. but in the cabin area. Anyone else have this problem?

I would remove upper dash panel ... Guage panel and check for a loose wiring harness, I have had some of the zip ties get old and brittle on the harnesses in ours and cause them to move enough to make noise.

Its on the port side over the bathroom sink area
