Your Turbo'd Passat has an intercooler, the air routes from the airbox to the turbo, down to a crosstube, across the front of the car to the intercooler and then to the intake manifold.

Where the flexible pipe joins the metal crosstube is where the pipe normally spliits or becomes disconnected.

Remove the undertray and follow the pipe from the turbo and you'll be able to check all the connections.
