You can configure your Volkswagen to use its rain light sensor (RLS) to watch for rain and automatically close (wind-up) the windows if it detects rain while parked & locked. Featured is a Golf Mk6 but the function works similarly on all VW's.
You will need a VW/Audi/Skoda car with auto rain/light features, plus a suitable scan-tool.
Think about safety issues before enabling this (especially if you dead-lock your car), as animals or children could end up locked inside.
