Change the transmission oil in 2007 passat?

VW recommends you NEVER change the tranny fluid. Most mechanics disagree, if you are going to keep the car beyond 100k, you should change the oil every 60k or less. I don't know the details, but you must use the tranny fluid recommended by VW. No other. You have to drop the tranny pan and let all the oil drain out. Replace the filter. Replace the pan. Add fluid. Do NOT use the "flush" method promoted by many shops. It can damage the tranny.
