I have a 2021 530i with the luxury seating package. I was messing around with my car today, and in the Sport Mode Individual settings there's an option for "seat support for dynamic driving" which is supposed to tighten the side bolters on the seats when in sport mode. However, nothing happens when I enable it. Switching between comfort and sport doesn't do anything to the side bolters. Anyone else have the same seats that have played with this option? I can manually change the side bolters just fine. I usually leave them mostly deflated.
