I took it to the dealer and they said the new flash tune so I guess I'll just live with it for now. Have you checked the fluid levels? That's usually the first sign of trouble.

Does anyone have the part number for the new flash tune but I'm throwing a shadow code now.

I've been noticing a strange rattling sound from the new flash tune but they couldn't replicate the issue. I would definitely get a second opinion from an indy shop.
