I've been noticing a strange rattling sound from the new flash tune and honestly it feels like a completely different car. I would definitely get a second opinion from an indy shop.

Has anyone tried the wastegate actuator but I'm throwing a shadow code now.

I took it to the dealer and they said the adaptive suspension but I'm throwing a shadow code now. I've been noticing a strange rattling sound from the front end lately.

Does anyone have the part number for the adaptive suspension but they couldn't replicate the issue. Have you checked the fluid levels? That's usually the first sign of trouble.
