S80 MY2004: switch trunk opener defective

Hello dear community Since yesterday I can no longer open my trunk with the button on the flap It started with the fact that during the ride on the highway suddenly along with the yellow warning triangle came the message: trunk cover open. Stopped, trunk was actually open. So shut again, but when getting in the flap was already open again. So again (somewhat harder, normally not necessary at all) closed and continued driving. Now don’t shut up – only with the remote control. So the electric one still works. The micro switch must have said goodbye. I had unscrewed the rubber cover and operated the switch directly: it sounds quite right, clicks as usual, but no reaction. Must see if I get the whole time unscrewed on weekends… The switch looks very (!) integrated. Has someone changed the switch before, or do I actually have to have the whole Ha Is it possible that the electronics have excluded the switch themselves with a possible short circuit so that the flap remains closed…?
