Scirocco Central

...now that the weather is sufficient to have the window open, I noticed sometimes as I pull away there is a sound coming from under the car. It sounds like im driving over some branches or wood or something but when I look under there is nothing under there?

Check under the front bumper. There's a strip of plastic that can get detatched if you scrape a curb or similar when parking. It just pushes/clips in, at 4/5 places. No tools required...One end of my strip got detached and made a similar noise.
