So, my 2019 2500HD has decided to start throwing the P1050 code. I understand what it means..... I cleared the code and added 2.5 gallons of DEF hoping to at least get by for a time. I'm in the middle of a move 175 miles away, and right now I don't have time to give up the truck for any repairs - the closing on this house is in one week and we need to get out. The code went away after adding DEF a few days ago, and the DEF level showed OK, but now, after another 350-mile round trip, the MIL is back on and the level readout is the usual - - . I'm getting 14.5 MPG pulling a 5,000lb trailer so I expect more DEF consumption with the lower mileage. I'm going to get it fixed, but my fear is that at some point the truck will put me in reduced power mode. Can anyone tell me the operating strategy when the P1050 code is stored? Do I add another 2.5 gallons of DEF and hope not to overfill the tank? Next week I need to pull a 10K camper that 175-mile distance, and I do NOT want to get stuck. Any constructive advice would be greatly appreciated. TIA

Hello . Have you found the fix yet. My light reappeared. I believe it might be a stuck float in def tank. I believe when I let the tank get low. The air allows crystallization to form on pump unit preventing the float from moving. My guess . What do you think?
