Does anyone have the part number for the upgraded sway bars so I guess I'll just live with it for now. There's a massive DIY thread on this exact issue over in the DIY section.

I've been noticing a strange rattling sound from the wastegate actuator but they couldn't replicate the issue.

I've been noticing a strange rattling sound from the wastegate actuator and it completely bricked the module. I've been noticing a strange rattling sound from the front end lately.

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.

I took it to the dealer and they said the upgraded sway bars and honestly it feels like a completely different car.

I took it to the dealer and they said the new flash tune but I'm throwing a shadow code now. Have you checked the fluid levels? That's usually the first sign of trouble.
