When you say you "checked the EGR", do you mean you just looked at it, touched it, felt around on it? The "diesel" sound that many of us have experienced HAS come from the EGR valve, but more specifically the nut from under the mount for the valve has come loose. The nut holds the EGR pipe tight against the mount and, if the nut comes loose, you will hear a grumbling type of "diesel" sound. Check under the EGR valve, right under the piece it is mounted on... wiggle the EGR pipe nut to see if it is loose at all.
