Ahhh, if I remember right, if you have access to an autocal, EFILive can read DEF level... For the next time, lol.Sometimes, when it freezes, it needs to fill all the way up to reset... But dealerships problem, lol.Joy... That's one thing I was surprised about mine... The DEF system never gave me any trouble, lol.I was busy and didn't have a chance to update, but i took the truck in to the dealer on friday for the DEF system maintenance countdown and CEL. When I dropped it off the service writer said "it's probably just the DEF tank heater, we've had to replace a few of those". Well, she called about 4:30 on friday..."It's not the DEF tank heater, and we don't what the actual problem is yet. It'll be at least monday at this point."
Whee.
Hopefully they find out the problem, soon!
Was your DEF filled all the way, and then parked outside at well below freezing?
It was about half full when it first happened. Temps at the time were between 5 and 25F. It warmed up significantly after that though and it never recovered. I'm super interested to see what they say. I need to get off my ass and buy a new code reader. I would love to know what the codes were.
I knew it was half full because I topped it off when it first started...I meant to say that, sorry![]()
Hopefully just a computer reset is all you need.
The DEF system is crap. Lol. Not what it does, just the design.
