I have a 2007.5 LMM that I purchased new. I have the
exhaust odor that enters the cab when the engine goes into regeneration about every 300-400 miles.

I'd like to get it fixed, but I am concerned if I do I might get
my truck back with more things broke. I understand from some that it is a major job to get to the downpipe.

For those that have had this done, what did the dealer do to fix the problem? Did it solve the exhaust oder problem?

Thanks

Sounds like an exhaust leak.
