2020 Chevrolet Silverado with 3.0l Duramax Diesel threw it's first check engine light just over a week ago. I'm continuing to understand why this happened and how to get home safety if it happens on a long trip... As some of you may know the DEF system is not something that should be cracked open unless you are really sure there is a problem. Any contamination of the system will cause really big long term issues so I don't take having the truck service by someone else very lightly. I go over the fact that the CEL is now gone after clearing the code and even the history code is gone after at least 8 restarts.

This is going to be a series of videos now. I expect to have 1 more when the fault is captured and 1 more "IF" I take it to the service center.
