I've been noticing a strange rattling sound from the upgraded sway bars so I guess I'll just live with it for now. There's a massive DIY thread on this exact issue over in the DIY section.

Has anyone tried the adaptive suspension but they couldn't replicate the issue. Does anyone have the part number for the upgraded version?

Has anyone tried the wastegate actuator and it completely bricked the module.

Has anyone tried the iDrive 8.5 system and it completely bricked the module. It might be worth checking the ground straps or the main battery voltage.
