Friend of mine is on a road trip back from Aztec NM to Greeley co, headed over wolf creek pass at the moment. Hes driving a company 2012 dodge 2500 ctd, only like 60k miles on it. He just called me asking why it keeps de-Rating itself. No engine lights, the info screen just says water in fuel and electronic throttle control, I dont know shit about those things and neither does he. Anybody know what it might be? (he did drain already)
