Don't cane it but don't drive like an old grandad, the engine needs to rev freely, and to do that as joe says vary the rev range, so that all the parts can bind and settle with each other. between 5-800 miles is the crucial area, if you go mad in that rev range then there will be repercusions.
You should be alright to give it some wellie somewhere after 1200 miles, and change the oil to some nice clean good quality stuff, like synta silver or something like that, and remember a genuine vag filter. Obviously don't go over the top as soon as you hit 1200miles as things will still be adjusting to final positions, but if you are careful and don't go mad then the engine will be fine.
