Has anyone had the issue where there is a faint "beeping" sound coming from near the dash? I recently purchased a 2006 XC90 and it didn't do this until a few days after we bought it. In reading other posts, I can only assume that it has something to do with a sensor, perhaps the park assist or proximity sensors are dirty(?), but I am looking for advice, please and thanks! I tried washing off the back-up cameras on the rear bumper, but it didn't help. Seems to happen mostly when I am braking, or going slow. As soon as it goes into park - no beep. It is definitely not the "door is open" or the "your keys are still in the ignition" beep; it's much fainter and longer of a tone.

Any information would be greatly appreciated! If possible, I would LOVE to deactivate the option.......

Thank you in advance!
