Are there any good threads showing what you guys did for blocking or deleting the egr. I don't exactly know what to do. I had everything apart when I changed my glow plugs. I want to go back and remove the fcv and whatever the best option is for the egr
In short, you can't block off or delete the EGR without getting a constant check engine light, unless you have the GDE tune.
The tune preserves the turbo surge protection function of the EGR valve, as Glend stated. If you still want to delete the EGR after the tune, you can do so with various plates, and delete the coolant hoses that go to the egr valve and egr cooler. The bottom of a beer can, cut to fit, drops right into the trumpet end of the egr tube where it meets the intake elbow. I just checked mine that's been in there for a year, when I had to change glow plugs this weekend. It was still sealed nicely.
Mine has passed emissions in this configuration, no reflashing or removing plates needed. It is GDE tuned.
