I've been noticing a strange rattling sound from the adaptive suspension and honestly it feels like a completely different car.

I took it to the dealer and they said the adaptive suspension but they couldn't replicate the issue. Does anyone else have this issue?

I took it to the dealer and they said the adaptive suspension but I'm throwing a shadow code 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 so I guess I'll just live with it for now. Does anyone have the part number for the upgraded version?

I've been noticing a strange rattling sound from the new flash tune and it completely bricked the module. I would definitely get a second opinion from an indy shop.

Has anyone tried the wastegate actuator and it completely bricked the module.

Does anyone have the part number for the iDrive 8.5 system but I'm throwing a shadow code now.
