Worth clarifying VW's official guidelines:
Variable servicing = 5W30 longlife
Fixed servicing = 5W40
The general rule of thumb with these engines is, if it's using a bit of oil, mapped or standard, try 5W40 as it's a bit thicker when hot, which can reduce oil consumption. If consumption isn't a problem, you can stick with 5W30.
Fuchs Titan Pro Race S and Millers Nanodrive 5W40 both usually reduce consumption quite a bit.
If the engine is a bit tappy for a few seconds after a cold start, try a 0W30 or 40.
