    Car info:

    Golf estate 2009 (58)
    2.0 140bhp diesel engine
    Engine code (CBD)

    Symptoms

    Low revs up to 2k care drives fine
    over 2k black smoke and occasionally stutters
    no power over 2k rpm
    No fault codes using my delphi dsc150
    my vagcom 409 does not connect
    Turbo whistle only slightly but every turbo diesel i have owned does it

    Things i have done

    Checked the actuator moves freely by moving it with vacuum tank not being mounted to the turbo (which it does)
    put a vacuum pump on the actuator and tested (it does move but only half inch possible an inch)
    disconnected dpf/cat and spray mr muscle in back end of the turbo
    shaft has a little play but spins smoothly and freely
    disconnets maf (no difference)
    changed air filter

    has anyone got any ideas before i replace the turbo

    The shaft shouldn't have noticeable play only end float, smoking with power loss all spell turbo issues if disconnecting it changes nothing then it's likely to be the issue get it checked before it go's properly and takes out the engine as well.
