How do you replace 2006 VW headlight?

Most new cars nowadays... (I sound like an old timer!)

There is a plastic ring that fits around the base of the bulbholder that you can twist loose, then pull the bulb holder out of the headlight lens assembly. So just reach around to the back of the headlight and find where those wires go in, feel for that ring that has tabs sticking out for your fingers to push against. Turn it counter clockwise to loosen it. Once it's loose, pull firmly and you will have the bulb in your hand, still attached to the wires. The connector has a little snap lock thing (common to most auto electrical connectors). Go buy they bulb first and you'll see what I mean, ask the guy behind the counter at your local parts house which bulb to get. Your parts pro might even be able to show you how to change it!
