The hatch has a tab near the bottom of the headlight. To open the hatch requires that the hatch unclip at the top and rotate on the tab, rearward, about 1 1/2 inches or so. After the hatch opens up to this amount, then the tab at the bottom will release the plastic catch and the hatch can be completely removed from the headlight.

The problem with the right side is that the hatch can only move rearward by 1/2 inch. This is insufficient to clear the plastic catch at the bottom so the door is not removable. This requires removal of the headlight to change the bulb.

Note that this is with the Depo's. Bosch may be different.
