My 2012 diesel has been running just fine. Took her in to the Stealership for passenger air bag recall and some bolt/alternator recall. Work gets done within the day. Drive it away and it almost totally stalls, check engine light and reduced power. Back I got to the Stealership pronto. They take it back in and 10 min later, it's back. Sir you have the EGR valve code, but we cleared it........ but just keep an eye on it. 20 min later on the drive home, check engine light, but she still drives fine.


Yeah, so the stalling, in my limited knowledge about diesels, I don't think had anything to do with the EGR Valve. I think they messed up and didn't reconnect something or something. But what I do find odd is that all of a sudden I have EGR/cooler issues when everything was just fine. A bunch of people I talked to have specifically without hesitation said that the Stealership is shady as sh!t
