Did a recent internet search and this guy described it perfectly as "s4 turbo making a whining noise like supercharger, whats wrong?
So I was informed by a guy that knew the previous owner of my car that the turbo was making a whining noise and sounded like a supercharger."

I am suffering from the same issue, any ideas to how I can get the dealer to check it out without resorting to me driving it, as murphy's law never works to my side.

My guess is that it's a ripped DV. Causes boost leaks that can significantly limit power and also makes noises audible from the intake. If you can log boost with a JB4 or if you don't have a tune use a cheap OBD dongle and an app like dash command to measure boost. If boost doesn't reach stock targets you have concrete evidence for them to investigate further. Don't let a dealer brush off your issues, they often do in turbo related issues since it's a labor intensive job for them.
