Question about exhaust odor in cab

1550 Views 7 Replies 6 Participants Last post by  Seth
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?

I had this same problem on my 08 LMM. Took mine into the dealer and they replaced the turbo down pipe that was found to be leaking by at the turbo connection. There is a TSB about this issue. Be persistant with the dealer... no one should have to deal with that smell in the cab of a vehicle.
