    I would wait for someone more technical than me. But I would think it can't be good for the car.

    That whistling could be due to a turbo imbalance (less common) or an air leak (more likely). Check all your hoses for any splits, and they can be quite small to cause a problem and all the connections as well for any leaks.

    As for the specific turbo model in that engine, I couldn't find what it is.

    Sounds like a cold engine to me and the Turbo whistling ,

    If you have a bit of a rattle when cold pop in some Oil additive , JML do a good one or are there some ceramic ones now,
