Make no mistake, I luv my 08 e93. But this issue is going to drive me crazy. I use my e93 as a dd. 25 miles each way. Mostly highway and by myself. The passenger seat has a vibration noise. On rough roads or smooth roads. Makes no difference. When I push on the seat back or bottom left side bolster , it stops. Let go and it comes back. Wondering if anybody has had this issue? And what should I look for being loose or a bushing missing?

Thanks,
Mike
