How did i do? 5/5 blue, 2/5 rest.

Hello,
What is this part next to the left of the engine? The car is running constantly in emergency mode, and there seems to be a bolt at the bottom blocking where it’s supposed to connect to a tube. The part has 2 connectors with only one in use. Can this be the cause of the car not running properly?
