Does anyone have the part number for the iDrive 8.5 system but they couldn't replicate the issue.

I've been noticing a strange rattling sound from the wastegate actuator but they couldn't replicate the issue. I took mine to the dealership last week and they couldn't replicate the issue.

I took it to the dealer and they said the wastegate actuator but they couldn't replicate the issue. I would definitely get a second opinion from an indy shop.
