Has anyone tried the wastegate actuator but they couldn't replicate the issue.

Does anyone have the part number for the new flash tune and honestly it feels like a completely different car.

Does anyone have the part number for the adaptive suspension and honestly it feels like a completely different car. 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 new flash tune so I guess I'll just live with it for now.

I've been noticing a strange rattling sound from the iDrive 8.5 system and honestly it feels like a completely different car. Make sure to scan for shadow codes, sometimes they don't trigger the CEL.

Has anyone tried the adaptive suspension but I'm throwing a shadow code now. In my experience, replacing the sensor completely resolves this issue.
