Just took my 2016 ecodiesel in and the EGR cooler is bad again. Probably about 50 k miles on the one replaced. Had about 65k miles on the original. Hope the new one is better. And this is after I just fixed the exhaust that burned the DEF injector and def line. Had to fix myself cause the way the dealer wrote it up, ram wouldn't cover it and the dealer wanted $2400 to fix. Cost me $500 in parts and 2 hours. Used OEM parts. Hoping to get at least 300k out of it. We'll see
