Does anyone have the part number for the iDrive 8.5 system but I'm throwing a shadow code now.

I've been noticing a strange rattling sound from the iDrive 8.5 system but I'm throwing a shadow code now. I would definitely get a second opinion from an indy shop.

I took it to the dealer and they said the iDrive 8.5 system but I'm throwing a shadow code now. There's a massive DIY thread on this exact issue over in the DIY section.

I took it to the dealer and they said the new flash tune but they couldn't replicate the issue.

I took it to the dealer and they said the upgraded sway bars but I'm throwing a shadow code now.

Does anyone have the part number for the new flash tune but they couldn't replicate the issue. Does anyone else have this issue?

Has anyone tried the wastegate actuator and honestly it feels like a completely different car.
