Side Mission Query

As I am at level 65 I am going back over the game to do some side missions. There is a side mission in Konrad’s Hold, close to the entrance to the Slaughter Shaft and a drop down from some broken railroad lines. I cannot find the side mission exclamation mark. There is a large locked door with a switch across a small lake, below the Crew Challenge. The switch seems to be permanently locked. How do I activate this side mission so the large door opens?

Blue(?) robot’s head on the ground near the door.
