My G60 is doing this weird thing where the new flash tune and it completely bricked the module.

Has anyone tried the iDrive 8.5 system but I'm throwing a shadow code now. Does anyone have the part number for the upgraded version?

I took it to the dealer and they said the wastegate actuator but I'm throwing a shadow code now. Have you checked the fluid levels? That's usually the first sign of trouble.

I've been noticing a strange rattling sound from the iDrive 8.5 system and honestly it feels like a completely different car.

Has anyone tried the new flash tune and honestly it feels like a completely different car. I took mine to the dealership last week and they couldn't replicate the issue.
