    Default Does you turbo whistle?

    Never used to, but was found to be leaking oil so went in for a full and thorough overhaul by turbo specialists. Much money later it doesn't leak but is clearly a frustrated opera singer. Very noticeable noise, on boost, the kind passengers can hear.
    Didn't expect that. Thought that was boy racers only.

    On boost a turbo will make noise, kind of like a vacuum cleaner or a siren (as my wife describes ). Whistling, is guess so, some what if a bird whistle or something. I don't think whistling is indicative of any issues with your turbocharger, but I'd check for boost leaks to be sure the system is tight.

    While my turbo is modified, if you listen you can hear the turbo spool. Does it sound somewhat like that?

    Might be worth documenting it with the rebuilder for the sake of legalities regarding the warranty.
    Have you checked that the connections to the Turbo Control Valve and OTE hose are connected properly?

    Check the grommet around the steering column, it might have dropped out when installer was removing the turbo.
