Logic of naming actuators in VW-group is simple it contains "N" + actuator number. The actuator number is unique. Here you can find fitting location, connectors and some basic information about actuators.

To our mind, actuators information is reference, so there is only simple search by number.

YZ Notes on fault finding:

I In the event of a fault the gearbox operates at maximum main pressure and harsh gear-shifting occurs. The main pressure cannot be measured directly. The main pressure is checked indirectly by way of the pressure on the multi-plate clutches.
