2008 f350 6.4 4x4 wrench light
Hi guys im hoping im in the right place for this thread. anyways we went camping last year pulling a small 16 ft travel trailer that only weighs about 3300 lbs. it was on flat and hilly terrain combined. About 150 miles. anyways I didn't know any better and didn't use tow mode and had it on cruise. halfway there the wrench light came on. stopped and turned off truck and light went away. off for rest of weekend. return trip came on most of the way. this is in very hot 30c above weather. but keep in mind when this happens NOTHING runs any different and everything is normal. Now , two days ago pretty warm, 80 mile drive light came on again. I was on cruise , hilly terrain. Nothing else out of the ordinary. just wrench light. stopped, light went off etc. coming home , I thought ill drive without cruise , 3/4 way home light came on again. I forgot , last year we did a second trip with the trailer to same place, but no cruise and tow mode and no light. wtf? Also, two days ago when it happened weird things happening. I had a quarter tank fuel, and truck was saying I had 11km to empty. when I got home and restarted truck later truck was almost empty , and was telling me I had 80 km to empty???? strange. sorry, just wanted to see if you guys have any ideas. truck runs fine.lots of power, shifts fine. is stock right now except cai.
