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?
