I don't have an X1 but I've had 3 BMW's with adaptive headlights. They all bounce a bit compared to non-adaptive lights. I think this might be more related to the self-leveling than anything else. If you've never had HID's before, that plus the sharp light cut-off make the movement quite obvious.
I can't say whether this is true of all cars with adaptive/self-leveling HID's, nor do I know if your car is behaving normally, but I can say that if you've never had such headlights before you will notice the difference compared to what you are used to.
