    Default Fault code P2075 help please

    My Vectra 1.9 cdti 150 has the emissions warning light on and car is going into Limp home mode i tried cleaning the egr valve and the Throttle body (both was clogged up a lot) but did not help at all, so i got my m8 that has also a 150 cdti and i tried both his egr valve and throttle body and car is still doing the same tried also his air flow meter

    the car starts and drives ok but light is always on if it goes into limp mode i can turn ignition off and on again the car will rev and go fine for a few mins

    Any help on this be grateful


    ( Edit: swirl flaps seems to be moving ok no signs of any being stuck etc )

    What about any boost hose leaks? Is there heavy smoke coming out of the car?

    Looking at your profile it's an '07 registered CDTI, does it have a DPF? (To check for DPF - check the door plate and there should be a number - if it's 0.5 you have a DPF and if it's 1.20 you don't have DPF).

    Trim : Design

    Engine : Z19DTH

    Year : 2005

    Probably swirl flaps, heres the Vx FR.

    Field Remedy: 2065
    Subject: Engine Z19DTH/ J - Intake manifold, swirl flaps, actuator out of order, DTC: P1109, P2075 set
    Models: Engines: Option:
    Vectra-C 2004...,Signum 2004...,Zafira-B 2005...,Astra-H 2004... Z19DTH,Z19DTH,Z19DTH,Z19DTH| Z19DTJ
    Complaint: Customer complaint about lack of power and SVS lamp on. The following trouble codes might be set based on the installed application: a.) EDC16 C9 (2-actuator strategy, i.e. pressure sensor as well as pressure regulator fitted at fuel rail) TECH 2 shows DTC: P1109. b.) EDC16 C39 (1-actuator strategy, i.e. only pressure sensor fitted at fuel rail). TECH 2 shows DTC: P2075.
    Cause: Problem might be caused due to sticking swirl flap or due to malfunction from swirl flap actuator.
    Production: Several modifications introduced since SOP. Latest improvement was a design change at the swirl flaps itself in order to make the flaps more robust and to prevent them from sticking. Engine-BP: Z19DTH17228334 (28.02.2007).

    Remedy:
    In case of customer complaint perform TECH 2 swirl flap actuator test
    in order to evaluate the problem.
    Recommendation:
    Remove upper beauty cover in order to see the swirl flap linkage
    mechanism. Switch on ignition (no need to start the engine) take
    TECH 2 out of the vehicle to the engine bay. Change into swirl flap
    actuator test and perform test. If linkage does not move at all but
    the actuator motor itself is working (audible) it might be that:

    Not 100% sure, but I would say it's part of the drive module - which is inaccessable unless you take the manifold out, which is a pain. The drive module sits under manifold, directly under swirl flap no 3.

    If there all moving it shouldn't be the problem, could be a actuator motor problem or as said position sensor, but not sure where the sensor is located, it could be in the motor housing?, by the way i would also clean the boost sensor if you haven't done so already.
