Hi, I am new to the VW Golf world. Just recently purchased a 2007 GT Sport TSi DSG from a private seller. It's in OK condition with a few little issues to address. One of them is the parking sensors beep when in reverse. As I get close to an obstacle, then the beeping gets faster until solid. That is how I expect them to work. But they shouldn't start beeping as soon as I put the car in reverse if there's nothing behind me. Any ideas how to fix this?
