My truck is stuck on limp mode i did a full service replaced all filters and oil and still have this error. I have done a diagnostics and i get a error u3fff code which doesnt tell me exactly what is the problem. Anyone that can help please on uphills my truck can only move 15km p/h on a downhill it picks up speed like normal. Turbo has been checked air pipes have been checked
