Check your handbook for infor, but generally speaking it's important to get an Oil that has the correct specific VW reference.
Realistically, it's unlikely to make a huge difference over time (as long as you change regularly and use good quality oil), but if your car was last service at a VAG garage, they will have used a specific oil that is worth sticking with and not mixing types where possible.
If you're doing a complete change yourself, then I'd recommend Castrol SLX or Mobil 1 - both excellent oils and based on Synthetic technology for longer service intervals.
