EGR Valve Flow Insufficient, Gotta pass emissions Options

[estaticd]

At the bottom I have another question.... please scroll down.

Hey all, I'm just trying to troubleshoot this problem on my own, which is probably a dumb idea but the stealership wants to milk me for $400-600 to fix the problem, which is pretty much out of the question.

My mechanic says it'll be far less than that, but even still... if I can fix it on my own it will always be cheaper.

The main question I want to know is if I can just disconnect the thing alltogether, since the emissions place I am going to does not do a visual inspection... but will not pass it as long as the CEL is on, which it is, and which it has been for awhile now.

And if so, how would I go about doing this?

Someone should do a writeup on this(if one doesn't already exist), cause I know lots of people have done this, and it seems to be a fairly common problem recently, but no one can get a real answer on how to do it.
Pretty sure I need to do it as well but have no real idea how, i've never even looked for it yet.

I did eventually manage to get it off: both the EGR and tube. It seemed damn near impossible at first but it really isn't that bad provided
you have the right tools (long socket extensions and such) and
you're not unwilling to get in there and disconnect other hoses, cables, wiring etc. to gain access.

I'll try to get back later with better detailed description if/when I find time but, right now, though cleaning the EGR valve, tube, EGR modulator valve (its filter, ports, etc) decreased my NOx levels significantly, it didn't solve my problem!
