You won't fail for level, they'll just adjust them at the time on the beam aligner. You can manually adjust by turning the thumbwheel on the top of each assembly. It's possible (with xenons) that the level sensor arm has popped off the suspension arm. Mine used to do that all the time and was a real pain in the arse.
