Simply follow the winterizing directions in the A4 manual. Remove pipe caps on port and starboard side of engine and loosen 4 screws on pump cover, water will drain out. Have been doing this method for more years than I care to remember without problems in our Ontario winters. The prestone method is messy and works only if the engine thermostat is open(hot engine), or if it is removed so that the anti freeze circulates through the block. Often people believe that if they see anti freeze being exhausted, that the engine is protected. Not necessarly so!
