I have 10,000 on my 13 Bighorn. I get a nasty burning Tin Can smell in the cab when I am sitting at a light or in traffic when it goes into Regen Mode. Never smell it when on Highway.

Anyone have this experience?

Possible bad door seal somewhere or???:

Yep I get it too along with exhaust fumes once and a while, Had the clamps on the turbo tightened as somebody on here suggested they might be loose and it did not help. Dealer has no clue.

Mine does it, maybe putting the climate control on recirculate would help. Haven't tried it yet

Mine too. I went to the dealer yesterday to set up an appointment for an oil change and a list of things for them to look into, one of which is the diesel smoke smell in the cab. I was able to tell them that if you open the hood, on the turbo side of the motor, there is a pulley with cables going around it (my guess it has something to do with the throttle). Mine was releasing exhaust right there. Whether or not that is the only leak I don't know. Dealer agreed that smelling high concentrations of smoke in the cab is not good at all because of the obvious health concerns (ie. Carbon monoxide). So if you guys could, check around that pulley, mine has got soot all over the bracket above it that holds the cables and I can watch smoke come out from around the pulley, especially when the truck idols up in the morning when I warm it up.

Diesel welder, in your opinion, do you think this could be the culprit, at least in my case? And I would assume that it shouldn't be leaking there, correct?

Absolutely correct !! That should not be leaking !! You shouldn't smell any diesel fumes in these new trucks....inside or outside.

Ok, well hopefully the stealer can fix it. Yeah, the first time I smelled it, my wife was in the truck and she had a fit. "Almost $60K for this da** thing and it smells like this inside...........". Oh, it wasn't pretty. She didn't want to spend the money on it either......another nail in my coffin.:doh:

They need to replace that valve of tighten up whatever is loose. That EGR system feeds right of the exhaust manifold. I could see how that would produce horrible fumes inside the cab !!

I wonder if a certain production run of trucks had this issue? Mine has never had any in-cab smell from regen.

I notice the in-cabin smell mostly when I'm hauling (when truck is under load) and I come to a stop. Not that it would help much but these things need a cabin filter.

I have the same smell in my 3500 I think it is the cross over tube for the egr it looks like it is burning off the clear coat they spray on the motor. The cross over tube when new was all the same color now on the exhaust side it has turned dark brown. However my 5500 has not had this smell and my cross over tube has not changed color.

Trowel13 says his has soot all over it and smells diesel fumes...not typical regen stank. He shouldn't have any soot around any of these areas.

I don't have the regen smell in the cab but when its super cold out here and stuck in traffic I get a hint of regular diesel exhaust in the cab, like the smell from an older truck with all the emissions stuff on it.:confused013:
