So my wife and I recently inherited a 2014 Chevy Cruze diesel from my mother in law because my father in law passed away. I know absolutely nothing about diesels…any help would be great just as far as normal maintenance to keep in mind. I have already had to replace the DEF fluid tank heater. Now just few days ago I got another check engine light and the code I read was P2598…I can’t really find much as to what it could be. Even worse, I really can’t find anyone in my area here who knows this care and is willing to work on it. Any help would be appreciated. Thanks!
