DEF level sender.

Well I have had my first issue with the new truck. Went sledding to the mountains this weekend. Kinda cold. Need to fuel up and checked def level before I pulled in. It showed 30%. Filled the truck up with fuel and went inside to grab some food and drink as well as a 2.5 gallon jug of def. Put the jug in and pulled off to the side to eat my sandwich. Def was still reading had gone to 29% in all this time. So continued on figuring the level would go back to OK. It never did. Went all the way to the mountains and back and on my way back (about 8 hours driving time) the def level is now at 28%. So I have plugged the truck in when I got home and unloaded and will see if it changes over night. Temps going to -30C tonight. I plan to get it in the shop for a few hours tomorrow to thaw out and see if maybe the def tank is partially frozen. I have seen it happen on the Mack trucks a few times. Hour in the shop and the tank is GTG. Otherwise I guess Im going to the dealer.

Probably frozen like you suspected. Bet the shop heat does the trick.

DEF sensor probably won't read correctly until it see's warmer weather. As above, it will be fine to drive.

See info on "Frozen Tank Status" here:

Washed the truck and put it into the crane bay this morning and cranked the heat. Was in there for 4 1/2 hrs. Still didn't read and stuck at 28%. Supposed to get warm this weekend so hopefully it thaws out then. I don't care if it thaws out when reading "ok" I just don't like it under 30% freezing up. Ill confirm that everything is good when it eventually thaws out. Its funny because I have thawed a few tanks out and it usually takes less then an hour with much bigger tanks.

During late summer I had the same problem. Took 1500 miles to reset in warm weather. Has worked fine ever since. Might not be frozen???

Mine was reading 28% the other day. I added 5 gallons. Thought it was only supposed to hold 5.3 gal but whatever. 300 miles and 2 weeks later it still reads 28%. A few days ago we hit 50+ degrees 2 days in a row. Definitely not frozen.
Going to the dealer tomorrow for the seat belt pre-tensioner recall and to have the TPMS reset. Can't even rotate your own tires anymore without an $80 tool so the TPMS can re-learn the wheel positions.

You can do the programming yourself. It is a bigger process to do it and I did print it out to do our escalades winter tires but never got around to it. You have to get into the programming mode and add air to each tire. Do a search and you can probably find it.

I am still at 28% too.
