My DEF was low with about 400 miles remaining. I had it filled at Elk River Ford. About two days later my check engine light comes on so I went to Boyer Ford in Minneapolis and find out that the DEF pressure is low and they messed with it for about 2 hours. The verdict was it needs a new DEF assembly mean pump and tank as it comes as an assembly. The problem is Ford doesn't have one available in the US so it has to come from the assembly line. I was given a time frame of a couple days to upwards of a week to get the part. Meanwhile I get to drive my $65,000 truck with it's balls cut because the computer de-tunes the power with the check engine light on. Boyer cleared the code but it came back on about 15 miles later.
I'm curious if anyone else has had problems.
Mileage has been hanging around the mid to upper 14's via old fashion math. My best tank has averaged 15.2.
