I cleaned mine this weekend and the code is now gone. maybe you didnt get the passages clean enough to stop the code. the pic at the top had nothing on mine. My passages were completely gunked up all the way up to the tube to the egr valve.
So far so good! the light is not back on! for now. And to avoid asking further stupid questions on where the heck is this thing located, i'm probably going to spend the money and get the hanes manual.
I'm working on getting a page set up on how i cleaned the egr. all the pictures i took with my digital camera need to be resized and saved under a different format because for some reason they won't load up onto geocities. Just wanted to keep an update
