There is no recommended running in period, or even running in service. Some higher specification performance cars non VAG have this (I know BMW M cars still do) as they run a different oil for running in period.
However as above, its advisable to vary driving style, speed and engine RPM for the first 1000 miles to sufficiently run the engine through its minimum and maximum operating limits which would in theory highlight any issue with the engine. It wouldn't be advisable to take it on a hard track day with a few hundred miles on the clock, but at the same time driving conservatively may not push the engine to its operating limits which would be of no benefit long term.
I have known enthusiasts and specialist carry out an oil change at 1000-1500 miles or so. Quick and easy to do and no harm in doing so but by no means a requirement in the service schedule.
You can run all Volkswagens (with a handful of exceptions, UP! etc) on either Fixed or Flexible servicing regimes. Fixed is a Time/Distance regime of approx 10k/12 Months. Flexible is a Longlife regime which is up to 18K/2 years using an oil quality sensor to detect when the oil needs to be changed.
Be wary of Flexible service regime with performance models, I have known cars set to flexible and require an oil change in less than 10k if driven hard. Remember it is flexible and UP TO 18k/2 years approximately so it not a guaranteed way to reduce servicing costs, and not recommended unless driving 25 miles or so a day with regular long distance, constant speed driving etc.
My advice would be any performance model should be serviced every 12 months/10,000 miles as an absolute minimum, with hard use/track days etc I would advise reducing this (based on personal experience) to 6 months/6000 miles. By no means is this a requirement for service schedule, or warranty etc but would certainly be beneficial i'm sure in the long run if the car is used to its full potential on a regular basis.
