    When pulling out of junction car just loses all power I have to dip clutch and rev it then it goes . Also when going I put foot down to overtake and again loses power for a bit then you can feel it gradually picking up to normal
    Any help appreciated

    Even though there are no fault lights illuminated I would still check for fault codes. Check the DPF to make sure it's not partially blocked. You can see DPF pressure readings and it's status on VCDS. Could be boost leak, check all the boost hoses from the turbo through the intercooler back to the engine.
    Look for wet oily patches on the hoses.
