We have had some cold weather in the last few months, today showing -24C on the truck thermo. The truck started just fine and I let it warm up for about 10 min while I got a coffee and a quick bite, however when I came back the exhaust from the truck smelled so bad. It could be that the DEF is frozen and is not doing its job, but I could smell a terrible sour smell from over 30 feet away. I could smell it for a few minutes while in the cab, but once I got to work it was fine. Anyone else encounter this?

I'm not really sure about this smell but the funny thing is that "sour diesel smell" in Google just brings up a whole bunch of info on a strain of marijuana called "sour diesel".
I sure would't mind that sour diesel as well

yes i have been smelling the same thing with the recent cold weather -27C as well. i just assumed it was the fact that the DEF had not started flowing yet. however i will be bringing it up to the chrysler guys just in case the next time im in for a oil change because it does not smell like that consistently every morning when i start it
Once I get in the truck and drive away I don't get any of the smell, my place of work is only 18 km away, and it is fine by the time I get there. I have only encountered it with very cold mornings when the truck first is started and is warming up.
