Does anyone have the part number for the wastegate actuator 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 iDrive 8.5 system but they couldn't replicate the issue. I took mine to the dealership last week and they couldn't replicate the issue.
