    Definitely turbo related, as it goes up and down with engine speed? This may sound silly but the alternator can affect electronic items, especially parts of the stereo system. I've had it on mine and as it's a V8 it definitely wasn't the turbo ;-) Coincidentally my alternator recently failed so I assume the suppression was the first thing to go. I'm not saying that this is the same as yours, but it may be worth considering.

    Mine was a whistle, not the ticking you would get from the ignition system, you could hear it with the stereo off but not when music was playing. I think it is caused by the alternator creating RF interference as it begins to fail.

    make sure there's not a boost leak at the hose between the intercooler and the inlet manifold, especially if it's de-EGR'd

    It is not at all unknown for the exhaust manifold gasket to breakdown and leak, giving a whistling/shrieking sound. It's usually caused by one of the exhaust manifold studs snapping and allowing the manifold to warp. The studs that break are often at the rear of the engine on cylinder no.5.

    Yes, I know - but is that whilst sitting in the cabin or whilst looking into the engine bay :p

    Could it be the internal temp sensor fan by the mirror switch? That's on the right hand side

    My thoughts too Landmark - but the climate control sniffer fan is more of an electrical whirr rather than a whistle...
