Subaru - Forester :: High Pitched Whistling Sound Comes Out Of Dashboard / Vacuum Leak
My mother, who is retired, has a Subaru Forester, probably a 2001 or thereabouts. It runs great, but recently whenever you let off the brakes, there is a high-pitched whistling sound that comes out of the dashboard on the driver's side. My mother claims that she took this to a mechanic and they told her that there is a small vacuum leak in the power brake line. They also told her that the leak was small and that there was no hurry to fix it (that was in April). Now it is August and my mother is still putting off fixing it because of the cost. They will have to pull out the engine and the dashboard to get to the leak. In the meantime, she continues to drive the car saying that the worst that will happen if it fails is that the power brakes won't work, but she'll still have her regular disk brakes, she'll just have to mash down her foot a little harder. Is this safe?
View 6 RepliesGolf IV R32 :: High Pitched Whistling Sound When Car Running At Idle
High pitched noise when car is running at idle and when not on the gas. Whenever I accelerate it goes away. Pitch/Loudness seems to be higher with RPM's. Could be coming from front of the car.
Checked so far:
I read some other posts about this and fully disconnected my aftermarket radio. I'm pretty sure it is not a ground loop as no power to HU shouldn't still create the whistle.
What I have:
I have an EIP aftermarket street exhaust. I checked the exhaust to see about the flapper, but I don't believe I have any of the items involved - maybe I'm wrong. After some more reading it sounds like a vacuum leak as it goes away upon acceleration. I need identifying what vacuum hoses are still in place/clamped off with having an aftermarket exhaust.
I do not have a CAI, just a K&N drop in.
Lexus GS 2013+ :: High Pitched Whistling Sound When Coasting At 60 Mph
I finally got a recording of this, after trying to describe it without much success. Dealer drove the car 2x and claimed they don't hear it.
Video here, turn up your sound... noise happens just as the gas is let off...
As you can hear (if you turn speakers up, recording isn't very sensitive), it's kind of a high pitched whistling sound or whining sound. Happens when coasting (foot off gas) at 60mph. In gear or neutral, same noise. Only around that speed, only when foot off the gas.
What do you think this is? Some have suggested wheel bearing but if you listen this is more of a steady high pitched noise, not a helicopter like sound.
Sierra :: 1997 - High Pitched Whistling Sound Around Throttle Body
97 Sierra K1500, 5.7 liter. High pitched whistling sound underhood in the vicinity of the throttle body. Starts after truck warms up and quiets down when accelerating. I've wiggled hoses, disconnected what I could without stalling engine, checked air lines into throttle body, checked air filter, etc. Sound does not change when I apply brakes so I don't think it's related to master cylinder. The only time it changes is when I accelerate, then only gets quiet until I come back to steady speed.
Truck has 85,000, runs great. No codes.
Ford - Explorer :: High Pitched Whistling Sound Coming From Under Hood
I have recently noticed that there is a loud, high-pitched whistling sound coming from under my hood that has progressively gotten worse over the weeks. At first, it would only occur when I had my AC or heat on and would stop immediately once i turned the AC/heat off, and will also happen from time to time when I accelerate. Now, this noise is happening right when I start my car and takes a few seconds to stop.

So I noticed when it started getting cold that my Jeep emits this extremely high pitched whistling sound and I can't figure out what's going on. I've taken it to two mechanics and both said it was a belt that needed to be replaced so I had the belt replaced and the noise persisted. I've noticed a few things about the noise, it only happens when it is approximately 30 degrees outside or lower; only while the car is idling (when I accelerate the noise goes away immediately); It only happens after I've gone above approximately 30mph; The noise will go away after I've gone through a series of idling and accelerating; and stops immediately once I turn the car off. The Jeep is almost up to 150,000 miles.
View 4 RepliesGolf V R32 :: Slight Whistling Almost Like Squeaking At Idle - Vacuum Leak / PCV System?
4601 DBP, just under 35k on it. At idle, i hear a slight whistling almost like squeaking. I took it to my independent tech and he showed me that if he removed the dipstick for a second while idling, the noise stopped, due to lack of vaccuum, so he believes its in the pcv system. I am still under powertrain and obviously federal emissions 8yr 80,000. Go start your R and listen at idle inside the car for a whistle or squeaking noise that seems like its inside the passenger dash.

Car suddenly started a high pitched whistling noise/metal on metal sound at highway speeds. It is intermittent, no noticeable pattern w/acceleration or braking. Similar sound at lower volume when the shock/spring is depressed (pushing down on that corner of the car). Louder at low speeds.

Very high pitched "whistle"(enough to give you a headache) as vehicle speed increases or fan speed increased. This will not occur on recirculate and will go away if a window or roof is opened.

Got a tire rotation a two weeks ago on my new 2013 Kia Forte (purchased in August 2012).Now, I have a very high pitched whistling noise coming from the rear tire area. The sound happens at all speeds. The sound is the worse at very slow speeds; the sound is also very bad at very slow speeds when I touch the brakes and turn the wheel.I looked at back tires from outside the car (not underneath the car). The mechanical set-up of back tires look very different than that of the front tires. The back tires have metal parts touching each other while the front tires do not.

There is a whistling noise that is coming from under the hood of my Jeep. It is more noticeable on cold days. It temporarily disappears when my foot is on the accelerator or after I have been idling at a stop sign for 30 seconds. The noise starts again when I start driving.

My first VW was a 2001 4-door Golf (Silver), traded to 2003 GTI (Silverstone), traded to 2006 Jetta Wagon (Blue). Then the wagon was traded for a SUV. Well last week, I have decided to pick up my 4th VW. It's a 2012 CSG 4-door GTI.
After driving the car for a week, and putting on 350 miles, I heard a high pitch continous "whistling" sound from the engine. Took the car to the dealer this afternoon. Tech came out and loosened the coolant reservoir. I heard a "pooof", sound of air build up. The tech said VW is aware of this problem. Something to do with the water pump bearing. It has to be replaced. They took the car in to replace the water pump.

IS F (2008-2014) :: High-pitched Hissing / Whistling Noise Coming From Engine At 1500 RPM
Usually after I run the car in manual/sport mode, I begin to hear a high-pitched 'hissing/whistling' noise coming from the engine. It sounds like a vacuum leak. It is audible while driving with the windows down.
I am having problems pin pointing the source, but it sounds like its coming from the center block. What is the right direction to the leak? It starts exactly at 1500 and cuts off at 2200 rpm (while in gear). 1500 to 3000 rpm while in park..
I have a Takeda intake installed and I re-tighten the fittings.
Jeep - Cherokee :: 2000 - High Pitched Whistling Noise In Cool / Cold Weather
My Jeep makes a whistling noise in cool/cold weather (~60 degrees and below) that no mechanic has been able to diagnose let alone fix the problem. Here are the details...
-high pitched whistling (can be heard inside and outside the car - very loud) only when temps are about 60 degrees and below-after 5 minutes of the car running-only when RPMs are about 2.0 or below.
However, RPMs can be higher when it is colder out and it will still make the noise-as you push on the accelerator, the noise gradually decreases until RPMs are high enough to completely stop the noise.
When temps are around 50-60 degrees, sometimes the whistling will stop after the car has been at a complete stop for about 1-2 minutes-If you turn off the car and let it sit for 1-2 minutes, then turn it back on, usually the whistling will be gone. It will need to sit in the off position for longer the colder the temps are. This problem has been ongoing for about 4 years.
Golf/GTI VI :: 2012 - Ticking High Pitched Sound?
I just got my MKVI late January, and it currently has 3k miles on it. 2DR CSG.
Almost everyday in the mornings when I drive my car to work, there is this high pitch ticking/clacking sound coming from the passenger side vent/dash/A Pillar area.
It only happens over dumps on uneven surfaces or when I launch from a stop/red light. Keep in mind I have a manual. Its a rapid ticking/clacking sound that goes with the uneven surface or any sort of vibration on the road.
It usually goes away maybe after 20 mins of driving (I'm thinking it has to do with the temperature warming up). Or if its sunny out, it just magically goes away.
I've brought it to the dealer at least 3 times with no cure, because it takes me at least 20 minutes to get there. The tech would literally have to come to my house in the morning and listen while i start the car up and drive to "duplicate" the sound.
I originally thought it was static coming out of the right speaker due to bad wiring. Had the right speaker replaced already, sound is still there.
Golf IV / Jetta IV :: High Pitched Noise / Whoosh Sound From Intake At Low Rpm When Car Is Cold
I have a 2002 jetta 1.8t with unitronic stage 2 ECU and following mods:
ssqv BOV with recirc fitting (so acts like a DV)
3 inch open downpipe
Water/Meth injacetion (-35c washer fluid)
Short ram intake+heat sheild.
Spring loaded wastegate.
So for a while now I could hear a very quiet high pitched sound along with a whoosh sound from the intake at low rpm when the car is cold, after 5-10 minutes of driving the sound changes to where i just hear the wooosh from the intake, no high pitched.
I went out, let my car park for about an hour or 2 in 0c temp. went to drive it,everything is fine, the car just hit 90c. so i floored it, but traction control was on and i have winter tires, so it barley got to 4k rpm. CEL started flashing, no throttle control, really annoying high pitched sound from engine bay with lightest touch of throttle. the trubo was boosting to 22 psi and holding up to 16 PSI at redline before this happened.
The car would struggle to stay at idle, massive vibrations. but after reeving to 2k+ rpm no issue staying at that rpm, no blue/black smoke from exhaust. i scanned it and only got misfire codes and this strange code : "17925 - power supply relay for ecu (J271 or J363): electrical malfunction"
I had to clear the codes 3-4 times and restart the car 3 times for the power supply relay code to go away. but all the misfires, the high pitched sound stayed. it would misfire while driving, then stop, and then again.
I also logged with VCDS, and flooring it from 2k rpm to 2.6k rpm resulted in 0 extra boost over idle (idle boost was 980mbar).
Is my turbo blown 100% because of that sound, or could it be something else causing the "dentist drill" sound? And what about the power relay issue for ECU, could this cause any of the symptoms?
Golf/GTI VI :: Whistling Noise At High Speeds And / Or High Winds
Alright I did a search and found these threads with no final resolution on each. My new 2013 has the whistling noise at high speeds (65+) and high winds. It's for sure not from the engine and coming from both the driver and passenger mirrors. I can hear it with either or both front windows down but not back windows. No whistle at idle or due to high RPMs. What is the Jetta TSB # or a fix for this issue.
