2019 Duramax Regen
If you have a L5P Duramax Don’t let them do the update for regens, mine used to to 4 to 6 hundred miles between regens, after the recall now 2 to 3 hundard miles

This thread has been interesting and a learning experience for me. My 2020 Duramax and first diesel vehicle was idling high yesterday. I thought it was too warm outside for it to be idling higher than normal. Now I understand why! Thanks for teaching this old guy something :)
