Girlfriend just bought a 2013 Golf 4-door. LOVE this vehicle, now I understand the VW thing.. Question: When we first start the car, if you're quiet you can hear a mechanical/electrical sound happen within the first 30 seconds. Kinda like something is automatically adjusting. I don't really know where its coming from. Similar sound as the electric seat moving, but its coming from outside of the cab. Is there something that auto-opens or closes or something when you turn the car on?
