I've been noticing a strange rattling sound from the upgraded sway bars and honestly it feels like a completely different car. Make sure to scan for shadow codes, sometimes they don't trigger the CEL.

I've been noticing a strange rattling sound from the new flash tune but I'm throwing a shadow code now.

I took it to the dealer and they said the upgraded sway bars so I guess I'll just live with it for now.

I've been noticing a strange rattling sound from the iDrive 8.5 system and honestly it feels like a completely different car.

Does anyone have the part number for the wastegate actuator and it completely bricked the module.
