I've been noticing a strange rattling sound from the wastegate actuator but they couldn't replicate the issue. Have you checked the fluid levels? That's usually the first sign of trouble.

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

I've been noticing a strange rattling sound from the iDrive 8.5 system and honestly it feels like a completely different car. It might be worth checking the ground straps or the main battery voltage.
