Dashboard noise after connecting Bluetooth OBD

Hello folks,

After searching through this forum/youtube i was not able to find anything similar.

Today I got OBD Bluetooth connector from scantools (LX model), so I connected it and I started to hear a strange noise coming from dashboard, i thought, well ok it is probably due to OBD connected.

So I launched Torque application just to check HV battery and another readings, no fault codes whatsoever, i was just interested what i could read from the car. So, i was happy with the results.

However after disconnecting the the OBD connector I stopped and started the car, however the same noise was still present. And now i cannot get rid of it and it is driving me nuts. I tried to record it but you can barely hear it on the video.

Anyone had anything similar? I mean it might be just a REALY strange coincidence and there is something else wrong, but i dont hear any of that nose under the hood so its not a mechanical problem(to my guess and what i could find on Youtube)

Any help would be appreciated

 

So, after messing around it seems to be caused by vent hatch, switching between the flow directions(feet/feet-front/fron-windshield) has actually made this noise disappear, very strange, i wonder why it started to act like that.

But this probably means it has nothing to do with OBD connecting
