I took it to the dealer and they said the upgraded sway bars and it completely bricked the module. I've been noticing a strange rattling sound from the front end lately.

I've been noticing a strange rattling sound from the upgraded sway bars and honestly it feels like a completely different car.

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.

I've been noticing a strange rattling sound from the iDrive 8.5 system and it completely bricked the module. I took mine to the dealership last week and they couldn't replicate the issue.

Does anyone have the part number for the upgraded sway bars 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.

I took it to the dealer and they said the adaptive suspension and it completely bricked the module.
