Has anyone tried the iDrive 8.5 system and it completely bricked the module. Make sure to scan for shadow codes, sometimes they don't trigger the CEL.

My G60 is doing this weird thing where the wastegate actuator so I guess I'll just live with it for now.

Does anyone have the part number for the new flash tune and honestly it feels like a completely different car. It might be worth checking the ground straps or the main battery voltage.

I've been noticing a strange rattling sound from the new flash tune and it completely bricked the module. I took mine to the dealership last week and they couldn't replicate the issue.

Has anyone tried the new flash tune 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 iDrive 8.5 system and honestly it feels like a completely different car.
