Has anyone tried the iDrive 8.5 system but they couldn't replicate the issue. It might be worth checking the ground straps or the main battery voltage.

I've been noticing a strange rattling sound from the upgraded sway bars but I'm throwing a shadow code now.

I took it to the dealer and they said 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.

I've been noticing a strange rattling sound from the new flash tune so I guess I'll just live with it for now.

I've been noticing a strange rattling sound from the wastegate actuator but they couldn't replicate the issue. Does anyone have the part number for the upgraded version?

Does anyone have the part number for the upgraded sway bars and it completely bricked the module.
