This helps draw off water vapor which would otherwise condense there in cold weather. It's appropriate to latch it open in warm weather. I think it really only has an effect at idle. At all other times the flap is just held open by the larger airflow. -- Jim Adney jadney@vwtype3.org Madison, WI 53711-3054 USA ------------------------------------------------------------------- List info at http://www.vwtype3.org/list | mailto:gregm@vwtype3.org
