Regen
How does regen work on the newer Duramax diesel? I have a 2013 that just turned 10,000 miles. I have noticed when the engine runs at a higher idle rpm when driving around town for a while. Running at highway speeds, sometimes in 5th gear, when the engine idle is elevated and the rpm returns to normal.
We are in our 3rd week of being on the road. Between campground stays, we take day trips and the usual driving around town for a few days. Yesterday we towed 90 miles with average speeds of 60 mph. Today we took a round trip of 60 miles with speeds of 65-70 mph. When getting back into town and prior to fueling I noticed the rpm were around 900 instead of the normal 600. Not knowing much about the regen, I assumed that sustained highway or elevated rpm's would clean the system but that is apparently not the case, No indication on the dash of anything abnormal.
Enlighten me.
