Spark3542-why not get the part number off of the EGR valve and see if the new dealer part number is different? If so replace with the new one as in numerous posts on another forum, the original one was superseded by a replacement that solved the limp home mode. If it is the EGR. Mine was, yours might not be. If I were home, I could give you the part number from the repair order but I'm traveling. steve tampa
