What does the egr do?
The EGR valve recirculates part of the exhaust gases (hence the name) back into the intake. The intent is to give unburned fuel in the exhaust a second chance to be burned, in an effort to reduce pollution. While is does do that, after a fashion, it is an "add-on" rather than a "designed-in" and does not work that well while having significant negative effects, as Zerohour3k has said.
