stewmair , heaps of info on EGR issues in various threads on here , use search function .
When you see with your own eyes the shear amount of buildup of what looks like gooey black sand right through the entire inlet tract ,then you wonder just how much of this stuff is going into the combustion process .Just pull out the Map sensor and check out just how Blocked/gummed up it is.
There will also be noticeable improvent in power/economy if the job is done properly , ie removal of the inlet tract Butterfly and the cleaning out of the Y-piece.
