I can’t exactly tell you that I thinks it’s a good guessing game, but my brother has a 17 an he’s had to replace his egr twice, and also the def system which was under warranty at the time, maybe he got a lemon! It’s hard to tell, but it’s been running great for a year now no problems, that’s all I can personally say. Someone more knowledgeable will come in I’m sure an have a few storiesWhat is the typical lifespan of the EGR?
My DEF tank was replaced within the mfr warranty. That was years ago.
