i have a 2012 f250 6.7 68000 miles the other day check engine light came on had it checked don't have the code number right now but any way it was the heating element and sending level of the def fluid tank that was bad.. so looking to see how much it cost to have it fixed.. but i remember getting a letter from ford believe it was in july that ford had extended the warranty on the def heating element and sending level unit out to 11 years or 120,000 miles though well into the dealer i go and sure enough element in tank was bad and they put in shop pick it up next morning and no charge.... believe total cost was like 470.00 had i had to pay for it
