not much more to add really.

Start car - hit the pdc button manually-
Walk around the X5, putting you ear next to each sensor, you should hear a clicking noise from all working sensors.

If no clicking noise then either , all your sensors are not broken(unlikely) or there is something wroung with your control unit.

hope that helps a tad
