    Hey guys, need some posts to view an article to see how to adjust the actuator arm properly.

    Installed the wastegate, but not sure if it's at the proper length. I'm getting p1557 as the error when hitting over 3000rpm at 3rd or over 120km/h -ish...

    Welcome to the forum. welcometomyturbodies

    This is a common code if you search.

    Fault Location:
    Charge Pressure Control - Positive deviation

    Possible Cause:
    Reduced power output.
    Limp mode.

    Boost Pressure too High.
    Hoses/Pipes incorrectly connected, disconnected, blocked or leaking.

    Variable Nozzle Turbo (VNT) nozzles stuck.
    Solenoid Valve for Boost Pressure Control (N75) defective.

    Possible Solutions:
    Check Hoses/Pipes to/between Components.

    Thanks for replying, i've actually seen this on many other forums. I have read the guides on here too. Trying to eliminate things one by one. The actuator is new so can't be that. Might be vacuum or turbo vanes (=S..). We'll see...

    Well the common thing as in the limp home mode is Check Hoses/Pipes to/between Components easy enough and cheap enough to check and replace.
