I've got the N. Amercian made car and can't hear the turbo.
I do hear engine knock under light acceleration...on dealer first tank of gas.
I just had to have the boost control module replaced and now the turbo is difficult to hear.
If you're getting a knock, switch to 91/93 octane gas per the owners manual. IMO a turbo should never be filled with 87 octane gas. This car will run on 87, just not very well. I switched to 93 and haven't had an issue since.
