My saga is 8 weeks long so far. I got the dreaded (150 miles until the computer takes over to the 5 mile limp mod) living 15 miles from dealer I took it in. wow 4 weeks later I get it back with a supossedly new DEF system , yeah right. 15 miles to home and 1/4 tank of DEF used according to gauge, back to dealer another 1/4 tank reading 1/2 tank. Prognosis is bad DEF pump module ? part #68192659-AF and according to dealer there are 500 + other trucks awaiting same item, and only 47 in the dodge supply system. Just In Time supply system not working ? obviously there is an engineering problem somewhere ? So a part was reported on its way to my dealer and after a total of 4 weeks the second time for the same problem. Maybe he said I will get my truck back by friday (if the new pump checks out) seems like on these forums that some people and dealer verified that the pump might not check out ????? This is my second pump. does anyone have any feed back on a REAL fix to this problem ? it would seem to me that these are all season/weather trucks and there should be a permanent fix. I know I live in Alaska but I also have a mercedes 3.0 RV engine that is running just fine in these weathers.
