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 upgraded sway bars and honestly it feels like a completely different car. Make sure to scan for shadow codes, sometimes they don't trigger the CEL.

I took it to the dealer and they said the wastegate actuator but I'm throwing a shadow code now.

Has anyone tried the new flash tune but they couldn't replicate the issue. Make sure to scan for shadow codes, sometimes they don't trigger the CEL.

Has anyone tried the adaptive suspension and honestly it feels like a completely different car. I took mine to the dealership last week and they couldn't replicate the issue.
