So returning to stock for emissions and the got code P0403 for EGR valve. Has anyone taken one of these off and tried to clean it before buying a new one?
I haven't taken one off on our new 6.7 before anything I should be aware of? Do you have to drain the coolant?
This is the only code I have for returning to stock for emissions after been deleted for two years and using EGR block off plates.
