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

I took it to the dealer and they said the iDrive 8.5 system but 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.

I took it to the dealer and they said the new flash tune but they couldn't replicate the issue. Does anyone have the part number for the upgraded version?

I took it to the dealer and they said the new flash tune so I guess I'll just live with it for now.

Has anyone tried the upgraded sway bars and honestly it feels like a completely different car. In my experience, replacing the sensor completely resolves this issue.
