    Apologies for the delay. Work commitments.

    Purchased a Vac tester and the ECU Talk cable was delivered.

    Vacuum Testing Results: with Needle valve completely closed

    T added Piece before VNT actuator = 12"Hg

    VNT actuator receiving = 28"Hg

    ECU Results:

    BTW, DI has a consult comms port not OBD2.
    This is the plug i have on the patrol. (PIC)

    The ECU Talk cable I got was able to give me the following codes using my laptop.

    Code 73: P3-Pump Comm Line
    Code 95: Turbo Pressure

    Cleared the codes but no change.



    Is my next step disconnecting the VNT actuator rod to see if rod moves freely? I have attached a pic of the VNT actuator at idle, still not touching the stop screw

    Do i need to check vanes now to see if theyre clogged?

    Thanks
