vios whistling

[richardtan]

Dear SiFus,:wavey:

I notice a strange situation in my vios '06 recently.
When the car reaches speed of around 77km/h , a whistle sound is produced. Its loud enough to be clearly audible.

It seems to come from the front passenger dashboard area. But i could not pin point where it came from.

As i press the accelerator harder at around that speed the whistling will happen and it comes and goes away every now and then but always at higher speeds.

Once, when i started braking the sound was also audible. Very strange.

Kindly could a Sifu advise what could be the problem? Why do cars whistle if there is no supercharger or turbo?

Thank you for reading.

regards
Richard

Dear Friend,

I can assure you nothing was done on audio.
I was listening to a radio station when i heard the whistling and it started when i accelerated into the highway. At first, it sounded like it was from the radio. It was as loud as the radio. When the whistling occurred again along the highway, i felt nervous as I never experienced this situation before. So, i switched to another radio station. Sama sama. I turned off the radio. Same thing happens. Confirmed: not radio or audio.

Thanks.:wavey:

Dear Friend,

Recently, about 1 month ago, i went for 40K maintenance and got many things changed as per servicing package.

I even replaced the driveshaft whose boots broke. Now with the new shaft, seems the wheel is straight again and smooth again.

My brake pads was inspected to be still in operational condition. I saw the brake still got some thickness left.

So, i doubt it is due to brake pads. But then i am just a greenhorn. Also, the problem occurs almost all the time during acceleration past 77 km/h or thereabouts.

thanks for your concern.
:wavey:
sincerely
Richard

Maybe is the sound of wind..? my ae111 got whistle sound at 120km/h if strong wind blowing n the sound is coming from the side mirror, the whistle sound is made by the gap between the door n side mirror, i tested many time to conform that.

How come wind sound occur suddenly? Before that he dont have the sound?

And seems like ae111 not that good

Try and check the wheel bearings...I heard if the wheel bearings are gone also can cause this type of noise...

1) What i mean is check the car for anything sticking out that cause wind sound..

2) After installing door visor the wind sound is gone.
