oem or aftermarket?
Well.. firstly welcome to (the safer world..) of volvos if you havent had one before..
Do you think the sensors are oem volvo or is there a possibility they have been fitted to the car ? big clue here will be are you getting the audio beep ing thru the sound system speakers ? the factory fit ones usually start making a noise at a fair distance, i would think maybe a metre from solid objects that can reflect sound..not sure about the setup on that year but usually there is a pam module in the rear bumper area thats doing the figuring out of signals from the 4 sensors and pushing data onto the canbus,,
