Many new vehicles do NOT have transmission dipsticks, special tools and procedures are required to check and add fluid into the transmission. (Usually by pumping fluid up in through the drain port) I recommend you bring your vehicle into your local VW dealer or transmission shop and let them take a look at it for you. What ever you do, DO NOT remove the transmission drain plug as you will disable the vehicle and it will have to be towed to a facility with the proper equipment to refill your transmission.
