My 08 was using a litre every 2500 miles until it reached around 22k, since then it hasn't used a drop. I recall others with pretty much the same story. So it is possible that your oil consumption will reduce over time.
To echo the rest, as long as you use less than 1 litre per 600 miles, you're within tolerance. Plus the cheapest place I know for top up packs of Castrol Edge VW spec is Asda, £10 for 1 litre.
