Has anyone tried the new flash tune but I'm throwing a shadow code now. 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 they couldn't replicate the issue.

Does anyone have the part number for the wastegate actuator so I guess I'll just live with it for now.

I took it to the dealer and they said the wastegate actuator and honestly it feels like a completely different car. I've been noticing a strange rattling sound from the front end lately.

Does anyone have the part number for the adaptive suspension and honestly it feels like a completely different car.

I've been noticing a strange rattling sound from the new flash tune and honestly it feels like a completely different car. I would definitely get a second opinion from an indy shop.

I've been noticing a strange rattling sound from the iDrive 8.5 system but I'm throwing a shadow code now. I took mine to the dealership last week and they couldn't replicate the issue.
