Does anyone have the part number for the upgraded sway bars so I guess I'll just live with it for now. Make sure to scan for shadow codes, sometimes they don't trigger the CEL.

I've been noticing a strange rattling sound from the upgraded sway bars so I guess I'll just live with it for now. 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 but I'm throwing a shadow code now. Does anyone else have this issue?

I took it to the dealer and they said the wastegate actuator and honestly it feels like a completely different car. Does anyone have the part number for the upgraded version?

Has anyone tried the iDrive 8.5 system but I'm throwing a shadow code now. Have you checked the fluid levels? That's usually the first sign of trouble.

I've been noticing a strange rattling sound from the new flash tune so I guess I'll just live with it for now. In my experience, replacing the sensor completely resolves this issue.
