Is this normal??

It doesn't sound bad at all, and it's not very loud but just wondering, i haven't owned a diesel before or a car with a turbo so it's all new to me

my dad has a Prius and it sounds very similar to the whistle type noise that makes as it's driving along

I'd like to know this aswell as I caught my exhaust the other day and pulled it off, and after re-fitting and listening to see if it's blowing I could hear the same and couldn't remember if it was like that before or not.

sounds about right to me!

Think mine does , can only hear it with window open though
