I'm having issues with my 2008 Volvo XC70 3.2 AWD. I hear this strange noise when the engine is running. I hear it almost all the time, but it varies in intensity. Sometimes it is quite intense when accelerating, at other times it disappears completely. At first i thought it was some kind of interference from the audio system, however the noise seems to be coming from the center console. Unfortunately I cannot further locate it. I took a small audio recording of the noise since it's hard to describe. I would be extremely thankful if someone could hint me in the right direction since I'm quite clueless.

(When trying to record the noise I had the engine running in neutral and was tinkering with the AC, when I turned the AC off, suddenly the noise disappeared, so I'm guessing it must be something with the electronics)

Here's the audio clip I recorded on the passenger side below the glove box:

Thank you very much in advance!
