Wiper Motor Parking?

[coomo]

Hi Guys.Am using a Polo 9n wiper motor on another older VW Project.The motor works fine, as its new.However when power is removed,it stops in any random position.
Ive checked the wiring diagrams, and cannot see any evidence of what is used to assure the motor "parks" in the same position.
Most older cars usually have some kind of capacitor.Does anyone know if the relay or another switching unit, allows the motor to park? Thanks.

Could be nr 19 or 99
The 9N3 the signal comes from the BCM
