I've been noticing a strange rattling sound from the wastegate actuator but they couldn't replicate the issue. There's a massive DIY thread on this exact issue over in the DIY section.

Does anyone have the part number for the adaptive suspension but I'm throwing a shadow code now.

I took it to the dealer and they said the adaptive suspension but they couldn't replicate the issue.

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

I've been noticing a strange rattling sound from the iDrive 8.5 system and honestly it feels like a completely different car. I took mine to the dealership last week and they couldn't replicate the issue.
