01 330i "cricket" / buzzing sound behind dash (audio included)

So I looked around the forum and it seems that this buzzing sound is quite common on these cars. Some ppl say it's the MPG gauge and others say it's the blower. No body seems to have video/audio so I took a couple of minutes to do one myself. Before I do any work on the car, I want to see if someone can identify what it is by listening to the vid I posted here: http://ift.tt/1o4XUNn



I tried to keep it as quiet as possible. Engine is off but key is turned to "Acc On" and also the climate control is off. Audio may be too low...headphones would help.

Let me know what you guys come up with. Thanks
