Hello!

That warning means the Diesel Exhaust Fluid system had a fault. If the warning is out the fault went away. You will most likely make the end of your trip as the system wont stop the vehicle. It would be a good idea to top off the DEF Reservoir if you haven't filled it in a wile

However if the lamp returns, you want to get it to Ford soon s possible. Anything with it should be under warranty.

What Customers are Saying:

AlvinC answered a question about my Ford truck that only someone with an in-depth knowledge of his subject would have known what was going on.

Rich DUSA

Because of your expertise, you armed me with enough ammunition to win the battle with the dealer. They are installing a fuel filter and fuel pump at no charge to me.

MollyUSA

I needed help with my car on Saturday morning....got a response in 5 minutes, and it was the perfect solution. Thanks again to your service.

Jason V.Kirkland, WA

I do know, after going though this with JustAnswer, that I can somewhat trust my mechanic but I will always contact you prior to going there.

BRNew Jersey
