Sound beeping at 120km/h & above

[vr2turbo]

both friend say from dashboard. Might be wiring.

Then could be something vibrating at that speed.
However sound coming from, sometimes may not be from there. As in ghost stories also sound can be from else where....hahhaha

I once had the yik yik sound too and can be heard coming from right side wheel, but after a long strenuous check, finally found that the left side rack end making noise (grease dried up), and all the while checking right side....

Doesn't sound like something loose. U know sound like whistle, that's why I thought my windscreen or what got lubang that the wind is blowing through there that is making the whistle sound haha!

but not exactly whistle if u know what I mean....but hard to tell u what is that sound though..

could be yr ventilation flap but this is along shot.
u know the aircon system has the flap which when switch can allow outside air to vent in.
overtine with frequent usage it can be loose.
try sealing it shut.i did that with my sis kenari as the car seems to let outside smell in.
i just wedge it as the flap was never used all the while.

worst is could be a bearing,any bearing.very tiresome to check as it happen at high speed.

According to two friends including TitanRev as one of them, sound coming from the dashboard. All the while I thought is gearbox problem but then a friend said logically if gearbox problem, if it is the final gear, u dun need to wait till 150km/h only reach the 4th gear. If u were driving normally, u would have reach 4th gear before 150km/h.



Ya, passed the rest house and only start speeding and it was around 2am that time.
Yes, speeding already that time only drop gears slowly, and then accelerate back up to 140-150km/h to maintain the noise sounding, cuz was troubleshooting where it came from.

That's the only description to give, nothing more how to give :frown: As long as hit the speed above 140+- to 150km/h and above surely have sound. I manage to test until 160km/h+-.

Sound still persists.



Sudden jerk, sometimes only when in P, slowly change do D got a bit, but very rare. Not when driving time. Driving time change gears no jerking.

Even my mech can't really figure out due to no proper road to actually test that speed.
But he said my gears appear to be fine and smooth gear change.

So is a very weird case.

On 2nd note, engine was replaced before due to previous engine overheated. Same stock engine. Maybe wiring could be the issue? Not done properly or so?

Can't be speed warning. As it is not beeping sound.

But a long yiiiiiiiiiiiiiii........ sound continuously. Seems to be louder when speed goes higher.

At 1st thought was wind noise, but don't seems to be the issue.

when moving stick from P to N or D will feel a sudden jerk its normal, at least u know that your gbox is not at fault.

some perdana owners also encounter an irritation sound then driving 80kmh above, searched high & low for the sound finally found out that it was from the chrome strip at the windscreen that creating that irritation noise. maybe u could check it out too.

I was thinking only through dyno machine can diagnose? So if on dyno machine, no wind coming through vents or anything.

During test drive did turn on and off air cond, same as well. Radio not on. Indeed a long shot. Some say wait till the sound get worse only see how. Then I was like, is like waiting for cancer to reach critical stage only sought for medical treatment then is too late adi or might cost more.

I don't speed all the time to 150km/h but then if there is a problem, I think we should not ignore.

Bring diagnose. Got lots of roads here that can hit those speeds.

I is scared Ya better leave it to him since he more familiar with roads there.
KESAS I still okay since i do travel there quite often

The stretch of Kesas that I always use is always full of cars, can hardly reach 100kph...

That time I use already 2am. Got lot of cars but driving at lower gears like 2nd and 3rd at such speed, the pick up damn good haha.

Brother, 2nd gear where can hit 150kph?.....

Haha! No that speed la, Can't remember at what speed already cuz just focusing on that soung.

Aiyah! then you at first say at 150kph got sound, after that you say all gears got sound......

Yes, swift to all gears got sound when driving at that speed, then it means i did hit 140-150km/h
Guess is possible but car is moving la not stationary

You can shift to 2nd doing 150kph, your engine over rev or gb sure kaput already....

Dunno, can't remember but I know did maintain speed at 150km/h but I'm quite sure all gears did change to see if sound still got to check if every gears is okay. But only test once, dare not try liao.

Later letup.

Never mind, will ask bro. Izso to push 150kph for all gears when we do the testing on your behalf.....hahahhahhahahhahahahahhahahhahaha

That one no need already, just D will do Cuz I dont want my gearbox to blow. Once enough for me. Just need Izso to listen to the sound.
