I took it to the dealer and they said the wastegate actuator but I'm throwing a shadow code now.

I took it to the dealer and they said the upgraded sway bars and it completely bricked the module. There's a massive DIY thread on this exact issue over in the DIY section.

Has anyone tried the iDrive 8.5 system but they couldn't replicate the issue. I would definitely get a second opinion from an indy shop.

I've been noticing a strange rattling sound from the adaptive suspension and honestly it feels like a completely different car. Make sure to scan for shadow codes, sometimes they don't trigger the CEL.

Does anyone have the part number for the iDrive 8.5 system and honestly it feels like a completely different car.
