    Engine : 2.0T

    Year : 04

    Mileage : 59.4K,

    Default spanner light.

    any help would be great.
    when putting foot down in 3 rd n 4th it goes into limp mode.
    iv had fault codes read p1105-fa.

    when checking boost pipes are they ment to become pressurized when car is parked but revving, revved to 3 or 4 thousand and my pipes still are not pressurized.

    cleaned egr, boost sensor, Barometric Pressure sensor and few other bits not sure of there names.

    thanks

    i tryed cleaning everything. i can stop limp mode by cable tieing the actuator (waste gate) open.

    will this damage turbo?
    any guesses weather its the map sensor or the vacuum solenoid?
    cheers

    right does turbo only boost when waste gate starts to open? revving in neutral pipes stay soft open wastegate and they become pressurized and have no leaks. im guessing the vacuum aint working how do i test this?
    iv tryed finger on pipes when ticking over and its got a tiny bit of suck.
