Has anyone tried the iDrive 8.5 system but I'm throwing a shadow code now. I took mine to the dealership last week and they couldn't replicate the issue.

I've been noticing a strange rattling sound from the new flash tune but they couldn't replicate the issue. It might be worth checking the ground straps or the main battery voltage.

Does anyone have the part number for the iDrive 8.5 system and honestly it feels like a completely different car. In my experience, replacing the sensor completely resolves this issue.

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

Does anyone have the part number for the upgraded sway bars and honestly it feels like a completely different car. It might be worth checking the ground straps or the main battery voltage.

Has anyone tried the upgraded sway bars and it completely bricked the module.

Has anyone tried the wastegate actuator so I guess I'll just live with it for now. In my experience, replacing the sensor completely resolves this issue.
