This info is found other places but I thought since there is a lot of new jetta owners coming in lately that this is also a good place to give them a heads up about VAGCOM alternatives. VAGCOM is a $350 obdII connector and software offered by http://www.ross-tech.com/ that you would connect to a windows laptop to change some internal settings in your car. In my case I wanted to turn off the horn honking when the car is locked via the key fob. A OBDII bluetooth dongle can be used to connect to an android device, to use a $20 app called Carista. You can then change the settings via your android device and email yourself your settings, here is the raw email I received from my car(2015 Jetta 1.8T Sport) after I changed a few things:
