That may be your opinion, but I know for a FACT on my car, it was not the metal flap. It was the actuator that turns the metal flap. The metal flap can not make that noise. It's a very loose metal flap that is incapable of making that specific noise. Even if it was the metal flap that was making the noise, the golf tee mod would make it go away because you're preventing it from turning.
