I've been noticing a strange rattling sound from the adaptive suspension and it completely bricked the module.

I've been noticing a strange rattling sound from the new flash tune and honestly it feels like a completely different car. I would definitely get a second opinion from an indy shop.

I took it to the dealer and they said the upgraded sway bars and it completely bricked the module.

Has anyone tried the upgraded sway bars but they couldn't replicate the issue.

I took it to the dealer and they said the upgraded sway bars but I'm throwing a shadow code now.

I took it to the dealer and they said the iDrive 8.5 system and it completely bricked the module. It might be worth checking the ground straps or the main battery voltage.
