Richard,
I was going in there just to clean out the EGR tube(snorkel) when I was having trouble with one of the E12 torx bolts. It was pretty cramped under the ridged line near the last fuel injector. I was just going to get the new EGR valve and gasket and whatever else before I put more effort into. I was also going to get a smaller universal joint or whatever can get to that bolt without too much restriction.
