Re: More DPFE Sensor information (updated with photos)
They won't replace it under warranty until the CEL comes on and the OBD-II code specifically says "Insufficient EGR Flow" or something to that effect. That takes a LONG time from the time it starts to fail. That means you go a long time with a lot of crappy mileage and driveability before they'll replace it free. If you feel like waiting it out, be my guest. Not to rain on your parade, but you'll probably be well out of warranty by the time that happens.
