Your saying, there are no driveability issues other than the lite? You need to use a scanner that shows live engine data and has freeze frame. The freeze frame may show what was going on when the problem occured. Egr passages all clean? I can't do much from here. Intermittent issues can be a pain to track.
You can take connector loose from egr and computer. Use a testlite to check for ground, with everything turned off. Shouldn't be any ground, unless wiring circuit is shorted. Terminals A--B--C ARE GROUNDS. Termi nal D is voltage with the key on.
