I think it's a bit premature to declare this as a DEF issue without knowing the code. The emissions warranty doesn't go beyond 80,000 miles IIRC, so that wouldn't help you in this case. None of the components listed in the warranty guide have anything to do with the DEF system so I don't think that would help you either, but the dealer would know better as the information is in their system by part number.

So at this point hope for something wrong with the engine itself.

Got mine into the dealer, and they did a "flash". They said there was a new one out since last June when I had it done last.

So far 400 miles and the light is still out.

Got my DEF pump replaced today and drove 20 miles or so and no CEL!!! I was talking with the service managers and this is only the second one they've put in. Not sure if that's good for me or not.
