I am an owner of a 2000 Jetta and I've wondered the same thing...as far as I can tell by the owner's manual the Jetta does not use "Power Steering" fluid it uses "hydraulic" fluid (Pentosin CHF 11S Synthetic to be exact). I've also just found more about it at: http://www.germanautoparts.com/Volkswagen/Jetta/Steering
Hope that helps!
This 2006 Jetta press release says that the Jetta has "electro-mechanical steering." That means there is no power steering fluid as is needed for a hydraulic power steering system. Electro-mechanical offers fuel savings, as there is no hydraulic pump that is driven all the time.
