Hi there. Sounds like the cabin air filter to the heating and a/c system is degrading and peeling apart. The stuff that is coming out into the cabin area is a filter full of dirt and debris. I recommend replacing the cabin air filter and the black sooty stuff will stop coming out. Old filters will make a bad odor in the cabin area, especially when the filter gets heated up.
