Lots of ham fisted ginger bears just use a pipe wrench, which splits the EGR. The good book then says it is supposed to be replaced if split, although for many diesels the dealers won't clean them. One hours labour to scrub one up to new standard is nearly the cost of a new valve (Might be more in some dealers).

Did you ever get the special removal tool? If so could you post up some pictures and measurements? Think I'll try to fashion my own
