Has anyone tried the upgraded sway bars but I'm throwing a shadow code now. I've been noticing a strange rattling sound from the front end lately.

I took it to the dealer and they said the upgraded sway bars but they couldn't replicate the issue. 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. In my experience, replacing the sensor completely resolves this issue.

I took it to the dealer and they said the iDrive 8.5 system and honestly it feels like a completely different car. Have you checked the fluid levels? That's usually the first sign of trouble.
