I have a 2007 A4 with the 2.0t motor. When the vehicle is idleing I hear a deep blub(blub blub blub) coming from the turbo. But if I rev it up it stops.
When I am driving If I drive it slow and don’t accelerate hard it is okay. If I accelerate to fast it blows huge amounts of blue smoke.

Can anyone help help me here?
