    I've read threads on a mod for disabling this flap but I wondered if mine actually worked.I've checked and the flap is open and I can move the flap manually with ease but I wondered if anyone knows how it's supposed to work?At idle the flap stays open on my car which after reading various threads seems wrong.The other ones I've read say that at idle the flap should be closed, has anyone actually checked their own car?I'd be grateful if someone could advise me on this.

    Open on idle will close as you pull away and opens again above 3500rpm.

    This explains why its open when I've checked.
