09 Jetta throttle hose is divided like this.

Hello, two side by side, the lower one is a small water pipe coming out of the cylinder head, the upper one is a water pipe, and the other one is an inclined pipe coming out of the breather pipe and the carbon canister solenoid valve. I hope my answer can help you. If there is something wrong with the car, ask the car master. 4S shop professional technician, 10 minutes to solve.
