Yes we get some sort of electronic buzz / whirr ...... sounds like something powering down. Not given it much thought
it could of been there all the time we have had the car, but never really notied it before,,Yes we get some sort of electronic buzz / whirr ...... sounds like something powering down. Not given it much thought
... this is loud, you can hear it over the engine while sat in the car..I have exactly same thing as on the video, but one cannot here that unless the hood/bonnet is open. I had intentionally test driven two CX-30s after I noticed that on mine and guess what - same thing on all of them.
The first video is similar to what we see in above post, but this sound is not heard at all when the hood is closed, so its not annoying: herecx30 booked in next week at dealers, so they can take a look as they have not come across this problem before...
In my case both are constant and do not go away unless you completely turn electrics off. Those may be normal because all cars I tested had exactly the same thing.That high pitch noise in the video is normal as far as I know of the skyactive 2.5. It’s the throttle body servo that makes the noise. It shuts off after a minute or two. My 2015 3 has done that since day 1.
It is normal..even though mine makes the noise all the time...🤔Sound in first post video is Normal, can be atmo temperature related, all Mazda's can/could do this it is not a fault....goes away after about 60 seconds, next door CX-3 does it (3 years old).
You may also hear on a stone cold engine start up a noise like car is running on 3 cylinders (fast idle) for about 60 seconds, again normal as this one is due to exhaust emissions and fast heat-up (engine lean out) of CAT.
Remove that engine cover. Place you hand on various items that do not rotate and feel for a vibration. If it's under other parts that could be hot take a piece of hose and place one end to your good ear and the other end gets moved around till you hear it at it's worst. If you can't place your hand on it place a screwdriver close enough to touch whatever you think it is. Show it to a tech or search the interweb. it sounds to me like a malfunctioning valve or a hose sucking air.I have been on our weekly trip in the car to the supermarket , and also noticed the noise whilst the car is running,
Currently stood 15 -25m away and the sound can be heard..
I have some sound files . But I'm unable to upload for some reason
But found this
