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!
