Its the dpf def emissions filter thingy. When I got a battery disconnect installed they told me to wait a few minutes after I truck off the truck as it could damage the emissions system

Probably just the DEF pump purging the DEF lines.

Your truck just wants to let you know it is unhappy with the microaggressions you have displayed to it lately?
