Maybe they're all lumped into different seat names, but looking at our option seat we have S451A - Active seat for driver, which is where the seat portion moves like a terrible massage to keep your legs from getting restless.

Other separate options for S456A - comfort seat, S488A - lumbar support, S494A - heated seats. We also have the cooling/vented seats but I'm not seeing the option for that.

On the sunroof....ours occasionally refuses to close from the vent position. Which seems to be a problem on all BMWs. Sometimes it'll close the first time, sometimes the second, sometimes it's 30 min later with me occasionally trying. I don't see it jamming like is shown in youtube videos, it's almost like a pinch sensor where it closes, then reopens.
