autozone told me it was the egr, but from what i read on rps even if it is the egr you might still throw the code so you might as well just replace both the egr and dpfe at the same time to saave yourself the time and hassle of doing it twice. Sucks dont it lol Id clear the light itd go like 5 days and as soon as I got on the highway coming home always at the same spot on the highway my check engine light would come on lol. It did that 3 times kind freaked me out lol
