Burning smell from under truck

My 2011 F350 has about 7500 miles now. From day one I always noticed a burning smell after I shut the truck down which appears to be coming from underneath the truck somewhere. Not too strong but definitely noticeable.

Has anyone heard of an issue like this?
Thanks in advance!

Maybe your just starting to burn off the oils and paint off the engine. I've never heard of one burning down yet ......... oh, maybe not so funny.

I guess crawl underneath and look for any obvious signs of burning.

I've had that happen a couple of times when I didn't drive the truck for at least 20 minutes after the filter cleaning started. Not a real strong "hey it's on fire smell" but a "hmm I think I smell something burning" smell. Do you have a short commute or take a lot of quick trips around town? Could just be that you're not putting enough miles on it when the burn-off starts.

I myself would like the cleaning message to stay up on the info screen until the operator hits the 'ok' button. It's only on for a moment and I mostly miss it.

of course, like 99 said, couldn't hurt to take a look and make sure something isn't rubbing on the exhaust or that some small leak isn't jetting hot exhaust on to something... these things can get some kinda hot, that's for sure.

Thanks for the replies. I crawled under there and didn't see anything out of the ordinary. The service dept at the dealer said the cat conv gets really hot during regen and that might be the cause of the smell.
I do usually drive short distances.

My money is on a regen taking place, and the truck not being driven far enough to let the DPF cool down.

I have stopped immediately after a regen a couple of times, and could smell what you are talking about. No big deal.....my 6.4 did the same right after a regen.

Mine did that when it was brand new. I thought something was wrong, turns out, I think it was just the new burning off. Doesn't do it now with 25k on the clock.

========================================
After my last oil change, I started getting smoke and smell of burning rubber. I stopped and out came a huge cloud of black smoke from my left front wheel well, I thought oh damn and trip to open my Hood but it didn't pop up when released. I fine pulled it up enough to release the catch and smoke just rolled out, I had to step back.. Well I found a rubber glove laying on the inside fender flange where the Hood Bumper rest when locked and its mate had fallen down onto the hot manifold and melted.. It took the next two weeks to get rid of the smell.. When I got back from my trip.. I took the one glove back to Ford and gave them the present and they present it back to the owner hahahaha Ford inspected to make sure no fire damage done to my Diesel wiring and sent me on my way...
Thanks I love this forum..

I have just over 5k on mine and I have noticed that smell several times. My wife even mentioned it the other day. I think it is just burning off the new, it like others have said stuck in a regen cycle.
