I would yank the EGR valve out and clean it thoroughly before replacing it. Hopefully that will do the trick.
As far as the turbo, it sounds like an exhaust leak somewhere. The noise you are describing sounds a lot like the y-pipe or bellows are cracked. I haven't had it happen personally, but it sounds similar to what you're describing.
