Hello... I have an 2003 XC90 T6 and I need to ID the hose that comes off the center of the intake manifold. It connects to a one-way Valve. The dealer has no ideal what it is and they want to know where it is routed. The problem is that it routes to another hose with two Ts on it that to route to other connectors, so I am not sure what to tell them.
Any Help would be appreciated.
