Golf IV / Jetta IV :: High Pitched Noise / Whoosh Sound From Intake At Low Rpm When Car Is Cold
Mar 1, 2015
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?

It's been pretty cold here and haven't started my R in 2 days at the most. I turned it over this morning and got this high pitched noise, like maybe a belt slipping or a bad bearing? The CEL flashed a few times then went away.
I couldn't stick around to check codes or inspect the bay, but what it might be?

I'm having a strange, very high-pitched, noise that seems to be coming from my turbo or (possibly) somewhere else in the engine bay. It sounds very screechy, and it may be paranoia, but I believe it also may have a slight metallic sound to it.
It all started yesterday after changing the thermostat housing for the third time in 2 days (autozone sold me a faulty, warped, housing that leaked after install). During this repair the engine never overheated (it did however leak fluid and go a little low) and the main point for replacement was a stuck thermostat. After finally getting it fixed I took it for a test drive and noticed the horrid noise after hitting a good amount of boost (no gauge installed). The noise occurs when boosting and doesn't happen when spooling in the 3k-4k range. I had no hint of the noise before this.
There doesn't seem to be any drop in performance and it still pulls hard. Hoping this to be a loose exhaust connection or boost leak. May be spooling sound escaping.
Mods:
- short ram air intake with an aem filter
- 3" turbo-back exhausted
- revo chipped
- 4 bar fpr

When starting in morning (even if weather is warm) or after car has sat for several hours, my 1999 Taurus makes a high-pitched whirring noise. Thought it was a loose fan belt, but mechanic said that was wrong. Have taken it to several mechanics and, of course, it doesn't make the noise after I've driven it there. Have to leave it overnight, which is HUGE problem as I don't live near public transportation. Noise occurs several times as I shift into DRIVE and then accelerate. After that, it disappears, then comes back again, if I leave it sit for several hours. One mechanical friend checked the tranny fluid and said it's fine. Also said it is probably not the tranny but didn't know what it could be. I took it to one of your recommended mechanics, but they couldn't find anything and said they didn't even hear the noise, although I did leave it overnight at their garage. (Won't go back there again.)

Have a very high pitched squeal on cold starts as well as when idle occasionally.
Bad compressor?

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.

I've been having some issues with the way my car is running today. Drove to the store, and he was fine. On the way home, he hit 4rpm and then dropped extremely fast. Then I stopped at a red light.. I went to go, hit maybe 2.5 rpm and it made this high pitched squeak and shifted really hard. I made it home fine after that, and no lights are coming on. I just changed my spark plugs not even a month ago.

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.

Having problem on mrk 6, sounds almost like a high pitched vacuum leak but I can't find it.

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.

I have a 337 with Injen cai. Well, I have since removed the cai due to the fact that rainwater/water during a car wash will run off the hood and onto the top of the inside of the drivers side fender (under hood) and eventually run down onto the filter itself, thus causing it to become water logged. This of course is not good. My question.. I've tried so many things to no avail.

After installing my cai, I couldn't find where to put this breather hose, I'm lost to if I need it and where to put it...

I have a 2010 Corolla S Got it brand new in november of 2009. Its been 5 years since I had it and never had this problem.
So this has been happening for a month now, and I can't figure out what it is? It only sounds at first startup of the day when the engine is cold and only sounds off for 1 second right when you start the car.

When it is cold (below 30 degrees) and above about 30mph, there is a loud high pitched squeal (rather like the pitch of a squealing hearing aide)that seems to come form the front drivers side. The colder it is, the louder it is.
When I am able to take it in it is too warm to hear it. What might be causing the noise and will they be able to figure it out if it isn't making the sound?

Need to determine the cause of a strange high-pitched squealing noise coming from the engine compartment of my 2008 Subaru Outback 2.5l automatic. The squeal happens only when the temperature is cold (below 32 degrees) AND I hit a bump. It happens more often the colder it is outside. The noise is definitely coming from the front of the car and seems like the passenger side but I can't be sure. It happens with the blower fan/AC both on and off so I don't think it is caused by that. It happens when the car is cold or driven for a while and warmed up.
It occurs at both high & low speeds. I checked all my fluids under the hood and everything is filled as it should be. There are no lights (check engine or ABS) on. Recommend any troubleshooting that I can try? I have not taken it to a mechanic yet as they might have a hard time reproducing the noise since it has to be below freezing and hit a decent bump. I attach a video that I took while driving last week on a 16 degree day and heard the squeal when I hit a bump. I had been driving for about 30 min when it occurred. I have more videos of the noise if needed.

This is kind of an odd ball problem since I have not encountered this before, but every time I turn my wheels full left or full right and start moving a really high pitched squeaking sound comes from the front of the car. Is it bad alignment or wear sensors on the brake pads rubbing? the brakes have a lot of pad left so i find that hard to believe.

Started my R this afternoon and got a new high pitch noise that I have never heard before. [URL] .... What it is?

I'm stuck in a bad situation. With my work schedule it will be literally a month until I have time to look at my car during daylight. I may be able to drop it off next week.
Anyhow, the R is making a horrendous high pitched noise while coasting to a stop. This starts at just under 30 mph and is most pronounced in neutral. Accelerating in gear stops it. It is loud inside and louder outside and there is some rough "clanking" associated with it. My guess is a belt or bearing. It is coming from the front passenger side.

Whilst driving on the motorway at the weekend I noticed a very load high pitched noise which seemed to be coming from the rear/centre underside of the car. It lasted for about 30 seconds and then went. It has happened before about two months ago and after the first instance I had the haldex and rear diff oil changed. On both occasions it has been very wet on roads with torrentian rain.

I drive a 2010 Golf Wagon/JSW, and when I'm going at speeds around +60 mph/90 kmph and lift off the accelerator a faint high pitched whirling noise comes on. As soon as I tap the gas pedal it goes away. What this could be?
It's been a week now since I've noticed this, I guess I've never noticed it before or it's getting louder..i don't know?

I seem to have this high pitched whistling noise as I am driving at normal speeds (starts at ~40-45 mph). It seems to coming from my rear drivers side, but I'm not entirely sure. My R has about 78,xxx miles and I haven't done this 80k....
