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.
Function description for pressure regulating
valve 5 -N233, safety valve 1
The pressure regulating valve 5
-N233- is located in the mechatronics unit as a safety valve for clutch 1. It
controls the oil flow for the clutch valve N215 and valves N88 and N89 to
control gear actuators 3-1 and 5-N. The safety
valve permits fast opening of clutch 1. This becomes necessary when the
clutch's actual pressure is above the specification value.
The valve is closed when unoperated,
and there is no pressure at the downstream valves.
