Jim,
I decided to buy a new BOSCH unit online (eBay) a couple years ago. I found conflicting information that the Doser Unit was supposed to be replaced ANNUALLY!!
Took a LONG time with many calls deep into Cummins before getting an old-feller who prided himself on keeping the old written manuals when all the young bucks decided to through them out in place of the digital versions!!
He told me the history on them, and said it used to be recommended, but after changing the computer programming, they no longer found it to be necessary. It was cheap enough and i was attempting to fix a constant dripping of DEF...which turned out to be a failed gasket and deteriorated seat and flange!
