Moving Actor with Sound


I wonder how to drive a sound volume when a car or airplane crosses the position of my player.
A Doppler Effect would be nice but not necessary. Is there a way to make the sound louder if the car gets closer and fade out when the source disappears in the distance?
I attached a Cue to my car (inside a blueprint) but the sound (no UISound) is always everywhere.

best regards
