Prius (2010-12) :: High-pitched Sound When Coasting?
Noticed the barely audible (with good ears) high-pitched sound that emanates from the car when you let off the throttle enough to prevent any charge or discharge bar from showing? It goes away if you completely release the throttle or if you press the throttle a tad bit more.

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.

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?
Golf IV / Jetta IV :: High Pitched Noise While Under Boost
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
Golf V R32 :: High Pitched Noise Coming From Rear / Center Underside Of The Car
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?
Golf IV R32 :: High Pitched Whistling Noise When Driving At Normal Speeds
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....

I have a 2012 golf R with about 25500 miles. I'm getting this high pitch noise coming from the front of the car. I can only hear it with the windows down. It is intermittent, sometimes doesn't show up sometimes there. Gets louder when I turn right. What am I looking at? Wheel bearing? I'm on coilovers.
View 8 RepliesGolf 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?
Phaeton :: High Pitched Noise Through XM Via X3
I think my setup may be unique in that I have an XM commander, and Christian at Enfig made a special cable so that I have power connectors to the CD changer and my XM commander unit. Christian did a great job with this.
My dilemma is that there is a high pitched noise coming through the XM when the engine is running. It is not loud, and is not as audible at lower volume, but with my hearing problems, it is louder to me than to others.
The noise is not there when the car is not started. I guess there is no filter running the power to the changer (I am guessing), and now my XM commander box. I would not even know what to do regarding a filter or where it should go. The CD still plays clear with no noise. I have not connected an IPOD yet to the X3, but since the power to the CD and the XM commander is coming from the car battery, I figured that was the culprit.
Also, if I did not need the additional audio inputs, the XM roady I had in my center console via FM transmitter had more volume and more bass than my XM commander via X3. The XM roady did not sound good at all via the X3, and the XM commander was clearly better via X3 interface.
Honda - Fit :: High Pitched Noise From Navigation DVD
I have a high pitched noise coming from my car's navigation DVD. If I eject the DVD, the noise goes away. It starts up again when I put the DVD back in. Sometimes it doesn't make any noise, but it's typically on the whole time the car is on. When I stop the car, it continues for a little bit, which makes me think that it has something to do with the DVD rubbing against something.
A few months ago, I would get sporadic errors about the disc that would go away if I ejected and reinserted the disc. Other than the high pitched noise, it seems to be running fine now. The main question I have is whether replacing the disc has any hope to get rid of the noise or if I have a bigger problem and need to repair the system.
Golf/GTI VI :: Medium To High Pitched Whine
Had my first drive with the windows down for a long time and noticed a new medium to high pitched whine, stays relative to engine speed. Not the turbo, its much louder than that, i searched about the water pump issues and no one seemed to mention any associated noise, just coolant on the driveway. Waterpump? Alternator?
View 5 RepliesGolf V R32 :: Loud High Pitched Squeal
While driving home tonight in the snow, about half away home I noticed the most god awful high pitched squeal sound coming from what sounded like the back passenger side of the car. The squeal was so loud it made me cringe. I couldn't really get any near 40 mph because I could hear it start and instantly it would become really loud and would only stop when I slow down almost completely and then maintain a speed around 30 mph. It's pitch black out so I couldn't conduct a real thorough inspection however a quick look over and I didn't see anything wrong.

I've got a steady and consistent high pitched whine coming from the rear of the car. It's only audible when the car is running idle and/or at a standstill, A/C and radio off. Also can't be heard while driving. I've ruled out any rear diff issues and thinking it might be the fuel filter. I recall noticing the sound soon after getting the car, however it's gotten more prevalent recently.

View 1 RepliesPrius C :: High Pitched Whining Noise When Braking?
I've noticed more and more that when I am braking that I heard a high pitched whining noise. Sort of this ultrasonic type sound. It will only go away if I depress the brake pedal very firmly after being completely stopped. However every so often the firm press will not stop the noise. I hear it more in the evening on the way home than in the morning to work, though I may not be paying attention as much in the A.M. due to morning brain fog.
I don't hear it any other time. I'm worried something is wrong with my inverter.
Golf VI R :: Strange High Pitched Whine And No Boost
I recently noticed that my Golf R was making a strange high pitched whine and it seemed like there was no boost. I took my car to the dealer, and it turns out that part of the CAI broke off (a mounting component) and made its way into the turbo, effectively destroying it.
My dealer was initially intending to cover the turbo under warranty (prior to investigation), but now that it is clear that a failure in the CAI caused the issue, they cannot (obviously) cover it under VW warranty. Unitronic CAI failure led to turbo failure.
The serviced manager did some research prior to getting back with me, and was somewhat puzzled since the Unitronic CAI displayed on their website looked slightly different from mine in that the component that failed was not there. The service manager called Unitronic and learned that the failed component was a known issue (it had apparently failed before), and thus they modified the design - hence the picture of the revised version did not match the older version that was installed on my Golf R. The Unitronic rep offered to replace the CAI - but did not mention anything about the failed turbo (when he spoke to the service manager).
I found the following thread which illustrates that this was a known issue: [URL] .... I just wish I had found out about this before it failed.
