Help My Car Is Poorly

[Grahambailey77]

I am a new owner. And a newbie to this forum.

I have a problem with the turbo on my x5 3.0 TD.

It doesn't boost all the time and makes a whistling sound so I know the turbo is spinning.

I hope I don't need a new turbo as that will be expensive. I am hoping and I reckon it could be a loose pipe or a hole in one of the pipes.

Pls help.

Does the car woosh at all on de-acceleration?

Not that I have noticed no. When the whistling is loud it drives fine. When the whistling is quiet no boost.

Bump! Can anyone help with finding out what up with her?
