Took my truck in on Monday the 18th and the dealer says it found a code for the DPF malfunction. I don't have the exact code number or anything, but the dealer and Ford didn't know exactly what caused the malfunction. They said it could be do to the fact that I have a Banks intake and have cut out the stock muffler...I don't really agree with that. They also said that if the truck continues to do this than I will have to return the truck back to stock condition. All the while I'm thinking I can't wait to get this thing programmed!!!
