    Arrow Vectra 1.9CDTI(120) Turbo Siren!

    Hi all,
    I have a funny feeling my turbo on my vectra is on the way out. With each Rev of the engine I can hear a Siren like noise coming from under the engine.

    it is an SRI- 1.9CDTI 54 Reg - 55k miles.

    I have seen some info regarding Refurb kits for replacing the bearings in a turbo, is this worth doing? Does it sound like it would be the bearings in the turbo?

    Is there anything else that would possibly cause an issue? at the moment, the car actually runs fine and there are no issues, only the noise it makes!. sounds like Im squealing down the road.

    Any info would be great .

    Are 100% sure it's the turbo & not the aux belt pully wheel?

    Pull the small vac pipe off the vac pump, if it stops then it is the turbo, if it still does it then its probably a pulley.

    There is only 2, a big fat one that goes to the break servo and a thin one that supplies the turbo. If you pull the small one it will disable the turbo so if the whine stops then it is turbo related if it carries on then its probably one of the rollers.
