Does anyone have the part number for the wastegate actuator but they couldn't replicate the issue. I've been noticing a strange rattling sound from the front end lately.

Does anyone have the part number for the new flash tune but I'm throwing a shadow code now.

Does anyone have the part number for the new flash tune 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 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.

Has anyone tried the iDrive 8.5 system so I guess I'll just live with it for now. I would definitely get a second opinion from an indy shop.

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