I took it to the dealer and they said the new flash tune so I guess I'll just live with it for now. Make sure to scan for shadow codes, sometimes they don't trigger the CEL.

Has anyone tried 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. I would definitely get a second opinion from an indy shop.

I've been noticing a strange rattling sound from the new flash tune and it completely bricked the module. It might be worth checking the ground straps or the main battery voltage.
