Indescribable noise

Hi

I have a noise. It doesn’t happen all the time but only when driving for 20 plus minutes. It disappears after a short while. It’s almost like some sort of venting is going on. I’ve only heard it when it’s quiet in the car (radio off, windows up etc). I’m going for the 3 month check after Christmas. I’ll say something then but any ideas? Rob.

Too many beans perhaps!

I heard it today too. Like some kind of electronic noise, coming from the speedometer. Did you find a solution for this?

No. Original post dated 8th December. Haven’t driven it since then

Could be a host of things. Perhaps the automatic air-conditioning is blowing air into a specific component/section of the car e.g. the cluster if it gets too hot from being in operation?

You are maybe right. The strange thing is, the sound is kind of "electronic", and it is not a "ventilation" sound.

Hmm, can't think of anything but could be something as harmless as a stepper motor/servo being operated to full clockwise to full counter-clockwise actuation. The type of routine that is done to ensure an actuator isn't stuck and fully opening and closing it keeps it from getting stuck.

Today I heard the same sound from the front of the car, very close to the Volvo logo. Could be the same sound actually.

My main concern was NOT to have this sound all he time in my ears while driving, as it could drive me crazy

Solved but not cured!!

It a suspension issue when the car has been driven for a few miles. It doesn’t do it when cold which is strange. It’s not a massive issue but more of an annoyance. It might disappear if the car is jacked up and dropped.
