Hello! My check engine light came on, and I got the P0401 code. After some quick Googling, it seems like it’s an EGR issue? Can someone confirm if that’s true, and if so, what’s the first thing I should check? EGR valve? Hose? Something else? Not a mechanic, so any simple advice would help. Thanks!
