Why does my CLK C220 make a hissing noise?

I started to hear a whooshing/hissing noise from the engine compartment, passenger side at about 1800/2000 rpm a few days ago and sometimes a little hesitation when accelerating. On Friday on the way home from work I lost power, wouldn’t rev past 2000 rpm, auto changing very early, although I could manually change gear.

Why does my Mercedes CDI make a hissing noise?

The hissing noise is almost certainly one of the pipes between the turbo and the inlet manifold leaking air, so not a vacuum leak, but a pressure leak.
