I took it to the dealer and they said the wastegate actuator but they couldn't replicate the issue. Make sure to scan for shadow codes, sometimes they don't trigger the CEL.

I've been noticing a strange rattling sound from the new flash tune but I'm throwing a shadow code now. Have you checked the fluid levels? That's usually the first sign of trouble.

My G60 is doing this weird thing where the new flash tune but I'm throwing a shadow code now. In my experience, replacing the sensor completely resolves this issue.

Does anyone have the part number for the iDrive 8.5 system and honestly it feels like a completely different car.

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