Gang, not trying to be a smart a** but am new to the diesel world and have tried to learn through here and other places, but some of these new sounds have me confused hope someone can help me better understand? I read about active and passive regeneration and think I understand that part but when i read about their truck experienced active regen- what does it do? I was driving up hill today pulling 4k car trailer the turbo boost showed 22-24 psi, I was in 4 the once then 5 the on another time when I started to hear a loud humming noise. Sounded like a fan on high but then stopped as I crested the hill. I heard turbos before and they seem to be a whinning associated with that. The sound came from the driver side-am thinking these turbos aren't whinners but more hummers...am I right? Or is what the active regen sounds like?
Again just wanting to learn more about this new beat Igot... Thanks for the help.
