Boost solenoid vacuum line

KNAQ7 · 03-28-2016, 11:18 AM

Hi guys,

Does anyone know where this short vacuum line coming out of the boost solenoid is supposed to plug into? It is the small black one with the green lettering.

Thanks!

I could be wrong but I think it goes to the wastegate actuator on the turbo. Weaves around in between the thermostat and water pump. I'll try to remember to look when I get home.

i think one is for the wastegate actuator and the other for E9x exhaust uses vacuum actuators too right?
my F30 doesn't have the other pipe because it has electronic controlled valve.

It goes right below it to the wastegate actuator. Right by the electrical connector.
