make sure you have the car warmed up before you go, I failed my check about a month ago because I just drove straight there. My NO levels were something around 750. I went again a week later having changed nothing, however I took a much longer route there, and my NO levels were something around 300

You need to test the EGR system to make sure it functions. http://shbox.com/1/4th_gen_EGR.html
This. A mechanic warned me that by removing my EGR valve the NOX might be too high with the sniffer. Check the valve and see if it's okay.

Not saying that this will work, but it has for two of my friends that swear by it when they had failed emissions testing in the past. They added a bottle of RXP to two tank fulls of fuel. That was all they did and both cars passed. I think one of them only did one tank, but none the less it may be an inexpensive and easy fix.

It is a fuel additive that you can get at Pep Boys and other places. It may be snake oil and I am very cynical about these things, but this one has worked in two cases on others that are as cynical as I am.
It is about $8 per bottle. No guarantees it will work, but that is the first thing I would try if I was in your shoes. I am naturally lazy and things that work this easy are my crack.
