XC90 Turbo Boost Control Valve location

Hi Guys,

As the discussion title suggests can anyone tell me exactly where the Turbo Boost control valve is located on a 2003 XC90 2.5T AWD please ? a picture would help a lot : ) I have a replacement coming and would like to know where it is.

Thank you Andrew

    Tcv is mounted to the side of the airbox under the maf area.
    Follow the three vacuum hoses (top one has red tape) to the tcv

  • Thank you.

    Found it , previous owner had left it dangling down amongst the hoses to radiator and it was also unattached/disconnected : ) hence the code error.

    I've seen some youtube vids where they have rerouted them away from the turbo ( different XC90 model ) hence my confusion when mine wasn't where it was supposed to be attached to the air filter box.

    Got a new one coming so will be an easy change over now I know where it is. Thank you
