Service position puts the flaps in a position, so that they and their actuators can be safely removed from their place. The area is very restricted, so, you might or might not be able to do anything "manually" with them.
You'll also need VAG-COM after the repair to reset the basic settings for the temperature flaps and recalibrate the A/C. If you don't do that, you might still not get proper air mixing, despite having replaced the flap motor with a good one.
