My light turned on yesterday (2014 Ford F-250) and I am having an issue with my reductant heater (code) also. I called the dealership and they said that it is only covered for 100k or 5 years (whichever comes first). They are getting me in on Monday the 31st (New Years Eve) since today is Friday, but I have to pay a $100 deductible. Please let me know where you got your information on this extended warranty because the Ford dealership is telling me it's not so. This is cutting it close with only 1 day left on warranty.
