Recently took delivery of an SE, with option of electronic climate control. On top of the dash is a sensor that look`s exactly like the sensor for an alarm, shown on page 26 of the manual. But it does not flash per alarm instruction`s, when activated by double locking of the door. Dealer has told me it`s not the alarm sensor, but a solar radiation sensor for the climate control. Doesn't make sense to me, has anyone any advice/information?
