2024 Chevy Duramax Engine Problems. My 2024 at4 is back in the shop with issues 6.6 diesel. 2024 ltz 2500 hd and on my way home got a check engine light, short story, back to dealer who reset and said gm is working on a fix.

First came check engine light and code for clogged particulate filter, dealer cleaned filter. New to the ideal of a diesel and have a few questions.
