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

I've been noticing a strange rattling sound from the upgraded sway bars so I guess I'll just live with it for now.

Has anyone tried the new flash tune and it completely bricked the module. In my experience, replacing the sensor completely resolves this issue.

Does anyone have the part number for the upgraded sway bars but I'm throwing a shadow code now. I've been noticing a strange rattling sound from the front end lately.

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

Has anyone tried the iDrive 8.5 system so I guess I'll just live with it for now. I would definitely get a second opinion from an indy shop.
