Loud turbo whistle/wooshing noise

[y197rbn]

Afternoon! I have an AUM 1.8t, the turbo seems to make a loud whistle like its leaking but it boosts fine, it only does this underload too, is this normal?

Also 3rd and 4th gear the boost isnt as strong, is that normal?

Thanks peeps

You've got a boost leak mate I'd say! Or perhaps your tip is collapsing

sounds like a boost leak to me also, maybe advisable to get it smoke tested... Where abouts are you?
