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 but they couldn't replicate the issue.

Has anyone tried the iDrive 8.5 system and it completely bricked the module.

Has anyone tried the new flash tune and honestly it feels like a completely different car. Does anyone else have this issue?
