more trouble!

Hi all,just bombed down the m6/m5 from manchester to deepest dorset,you may have noticed me adding a little extra to global warming,yes that was me just in front of an intermittant cloud of black smoke(sorry about that),together with a strange (windy ?)noise and a very noticeable surgeing when the engine wanted some turbo.could this be a maf sensor problem or maybe a split or perrished hose or is my turbo about to empty my wallet? would appreciate any helpful input or suggestions. chris.

You might have answered your own question, it sounds like a split hose, the pressure from the turbo will be leaking from it causing the noise,

yup,thats what it was, top hose split & egr valve was coked right up,going great again now !thanks.

aint ya gonna remove the egr gubbins then?

yes done all that.all bright & shiny now.
