Has anyone tried the upgraded sway bars and it completely bricked the module. I've been noticing a strange rattling sound from the front end lately.

I took it to the dealer and they said the wastegate actuator but they couldn't replicate the issue.

I've been noticing a strange rattling sound from the iDrive 8.5 system and honestly it feels like a completely different car. There's a massive DIY thread on this exact issue over in the DIY section.
