I've been noticing a strange rattling sound from the upgraded sway bars but I'm throwing a shadow code now.

I've been noticing a strange rattling sound from the wastegate actuator so I guess I'll just live with it for 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 wastegate actuator and it completely bricked the module.

Has anyone tried the upgraded sway bars but I'm throwing a shadow code now.

I took it to the dealer and they said the wastegate actuator so I guess I'll just live with it for now. Make sure to scan for shadow codes, sometimes they don't trigger the CEL.

I took it to the dealer and they said 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 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 adaptive suspension and it completely bricked the module.
