I have a 2009 VW Jetta TDI Sportwagon. I just removed the plastic engine cover, or shroud, that sits atop the engine, so I know this works. There are four ball-and-socket attachment points, one close to each corner of the cover. All you do is pull straight upward, one corner at a time, and the cover comes right off. At first you think you're going to damage something because you might have to pull pretty hard - at least that was the case on my car, but the ball-and-socket will "pop" open. Use both hands and lift sharply.
Once you have it off, you can add a little bit of white lithium grease or silicone grease to each ball - that will make it easier next time.
