I have noticed that after a period of driving our new Fleetwood Expedition 40x there is diesel exhaust smell that can be noticed in the front cab. It doesn't happen when first getting in and driving, ...
The DPF, not DEF, is what makes the exhaust not smell like typical diesel exhaust. It still has a smell do it, though it's not very strong unless the DPF is going through regen.
If you are smelling typical diesel exhaust smell then there's not really anything else that could cause this other than an exhaust leak prior to the DPF.
Hopefully Fleetwood will be able to locate the problem quickly!

We stopped yesterday to check into the camp site and the smell was present before stopping, and got really worse after not moving and did come from the rear.
Anyone experience this? Could it be the DEF cycling into the exhaust system as it does seem to go away after driving some time down the road. Even so how is it getting into the MH when going 60 mph down the road?"},"Conversation:conversation:733456":{"__typename":"Conversation","id":"conversation:733456","solved":false,"topic":{"__ref":"ForumTopicMessage:message:733456"},"lastPostingActivityTime":"2013-09-30T04:22:19.000-07:00","lastPostTime":"2013-09-30T04:22:19.000-07:00","unreadReplyCount":18,"isSubscribed":false},"ModerationData:moderation_data:733456":{"__typename":"ModerationData","id":"moderation_data:733456","status":"APPROVED","rejectReason":null,"isReportedAbuse":false,"rejectUser":null,"rejectTime":null,"rejectActorType":null},"Revision:revision:733456_1":{"__typename":"Revision","id":"revision:733456_1","lastEditTime":"2013-09-27T05:52:55.000-07:00"},"ForumReplyMessage:message:733466":{"__typename":"ForumReplyMessage","id":"message:733466","conversation":{"__ref":"Conversation:conversation:733456"},"author":{"__ref":"User:user:231128"},"revisionNum":1,"uid":733466,"depth":1,"hasGivenKudo":false,"subscribed":false,"board":{"__ref":"Forum:board:Motorhomesforum-board"},"subject":"Re: Exhaust smell","readOnly":false,"editFrozen":false,"moderationData":{"__ref":"ModerationData:moderation_data:733466"},"parent":{"__ref":"ForumTopicMessage:message:733456"},"body":"The DPF, not DEF, is what makes the exhaust not smell like typical diesel exhaust.

If you are smelling typical diesel exhaust smell then there's not really anything else that could cause this other than an exhaust leak prior to the DPF.
Hopefully Fleetwood will be able to locate the problem quickly!","body@stringLength":"418","rawBody":"The DPF, not DEF, is what makes the exhaust not smell like typical diesel exhaust. It still has a smell do it, though it's not very strong unless the DPF is going through regen.
