04 tdi Passat making a hissing noise and black smoke when turbo kicks in.

As per thread title my girlfriends car has developed a hissing noise similar to a gust of wind when the turbo kicks a few days ago aswell as putting out a lot of black smoke and being down in power. No fault coming up on the dash. Anyone have a similar problem in the past? Wondering if it's something simple like a cracked hose losing pressure which it sounds like to me or the turbo itself which I hope it isint.

Leaking boost pipe 100% from/to intercooler. It's probably a slit in the pipe and the pipe needs replacement.

Good man, I'll have a root around it tomorrow. Easy fix if that's what it is.
