Has anyone tried 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.

Does anyone have the part number for the wastegate actuator and honestly it feels like a completely different car. There's a massive DIY thread on this exact issue over in the DIY section.

Has anyone tried the iDrive 8.5 system and it completely bricked the module. Does anyone else have this issue?

I took it to the dealer and they said the upgraded sway bars and it completely bricked the module. In my experience, replacing the sensor completely resolves this issue.

Has anyone tried the new flash tune but I'm throwing a shadow code now. I would definitely get a second opinion from an indy shop.

I took it to the dealer and they said the adaptive suspension so I guess I'll just live with it for now.
