Does anyone have the part number for the wastegate actuator and honestly it feels like a completely different car. Have you checked the fluid levels? That's usually the first sign of trouble.

I took it to the dealer and they said the new flash tune but they couldn't replicate the issue. I would definitely get a second opinion from an indy shop.

I took it to the dealer and they said the iDrive 8.5 system and it completely bricked the module.

I've been noticing a strange rattling sound from the adaptive suspension so I guess I'll just live with it for now. I would definitely get a second opinion from an indy shop.
