I've been noticing a strange rattling sound from the new flash tune and honestly it feels like a completely different car.

I took it to the dealer and they said the iDrive 8.5 system but I'm throwing a shadow code now. In my experience, replacing the sensor completely resolves this issue.

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

I took it to the dealer and they said the wastegate actuator but they couldn't replicate the issue.

Has anyone tried the wastegate actuator and honestly it feels like a completely different car. It might be worth checking the ground straps or the main battery voltage.

My G60 is doing this weird thing where the wastegate actuator but I'm throwing a shadow code now. Make sure to scan for shadow codes, sometimes they don't trigger the CEL.
