Back edge of top hits legs on underside of cover on open
I have an intermittant problem when I open the top. Occasionally the back edge of the top snags on what I guess are support legs on the underside of the storage compartment lid. It seems like the hydrallic system looses a little pressure causing the lid to shift slightly forward right as the back edge reaches the support legs. The were foot extensions on the bottom of the legs that I removed to get additional clearance but still can get a snag. I now only open the top up with the key so that I can manually hold the lid back in case in sags downward. Any thoughts on what maybe be causing this. One Indy BMW repair shop thought that I would have to replace the hydrallic pump.
Pic Attached. The camera angle in this shot makes it look like the edge will hit the leg. But this time the lid did not droop and there was adequate clearance.
