Mine just came back from the dealer. Besides some other things they did, my "concern" of the 2nd failed EP (and all the weird things it does to the EGR and the loud/quiet etc.) was not documented on the ticket and the SA wanted me to talk to the tech about it.
Got in and right off noticed it was running smoother (sound), started smoother too. So far performance is about the same as far as I can tell also. Got home and discovered it was indeed flashed. So far so good although, the later '04's are included in the recall yet. I'm sure the reflash is it, just no recall yet.
They also replaced the EGR with the new style since what they put in last time (recall last summer) was the old style. The new one is supposed to operate better and be less prone to goop build up. Also replaced the EGR cooler thinking that may be what was causing mine to splatter coolant. I mean splatter as in it was sitting just at the LOW line on the bottle and that loss took almost a year to do.
