2014 GWV Legend 3500 I4
Thanks for the interesting link. Just to be clear, though: the referenced text is referring to the DEF lifetime, which is not quite the same things as a recommendation for 2-year flushes. Vehicles driven regularly take care of this issue automatically due to normal DEF consumption. Valuable information for low-mileage vehicles, thoughI re-bumped into the link where the replace DPF at 2 year mark got logged into one of the folds of my brain. Look at the top of page 30 in the attached doc in this post: https://sprinter-source.com/forum/showthread.php?t=16355
I knew it was more than the manual, but sometimes don't remember where I found/saw things.
