what does the symbol 1 and a reverse arrow mean in white ?

Hi, my name is Devin. I am an auto repair expert with the Car Genius team here at RepairPal. I'm having trouble finding a symbol that perfectly matches the one you described in your Golf SportWagen. My best guess would be that the symbol with "1" and a reverse arrow in white indicates that the transmission is in manual mode, and it is prompting you to shift up to the next gear. This is common in vehicles with a manual shift mode, where you can manually control the gear shifts. The "1" represents the current gear, and the arrow suggests that you should shift for optimal performance. If you need more advice, have any other questions about your vehicle, or would like to get connected to a RepairPal Certified shop near you, we have you covered.
