I was driving up a mountain when a loud bang occurred. Engine lost power and could not climb hill/mountain. Large amounts of black and white smoke came from the rear of the coach. I was stuck on the side of the mountain for 14 hours before someone could get to us. This is the second time this issue has occurred and is associated with the dpf mil lamp coming on.
