This looks interesting. I’m assuming that if it fits an X4 it should fit an X3.
When I look online at the part number it seems to be a 3 series compatible part, which does not cross over to the X3.
Update:
Unfortunately this appears to be the case, it’s a 3-series part that will not fit an X3 (or X4)
