Passat (B6) :: High Pitch Sound - Possible Boost Leak
May 8, 2012
So i have a '06 2.0t 6spdman passat. I started getting this high pitch sound (like a boost leak) when under hard acceleration from second gear and up. I went to the dealer today and they replaced my PCV system, and told me that was the noise i was hearing. Pulled out of the dealer like half a block and same thing happened. Then the tech went with me heard the noise, went back put it on a lift. And proceeded to just rev the engine. They say its my Intake system, yet I have had it on the car for 2 and a half years. Could it possibly be the DV???

I lost boost, went from being chipped at 16psi to 7-8 with a check engine code and a high pitch noise. Now is the secondary air pump connected to the turbo in any way. It just happened and I'm working on getting the code read. Just curious if my pump is just bad, what im figuring.

The tone of my horn changes intermittenly from normal sound to high pitch. The high pitch sounds similar to a Japanese made 4 cylinder...for lack of a better description.

The symptoms are as follows.
-No change in performance, functionality, or spooling.
-Loud intermittent screeching noise when building boost above 3500 RPM
-Can only describe the sound as air escaping from a tiny hole, VERY similar to warn brakes, that kind of screech. The intermittent part I would describe as if you were tapping your brakes (and they were screeching) rapidly, so on off on off very quickly.
-Also happens when I let my foot off the gas (Also above 3500 RPM)
-Car has CTS Turbo Intake, 42DD Downpipe, and APR stage 2 software.

I went to go start my LS460... put the heat on, its fine.. when I turn the heat up on high I get this annoying high pitched sound. It has to do with the heat system because when I turn it off it goes away... I'm scared to keep the car running...

what could be causing this. The faster I go the higher the pitch sound. It only occurs when pressing the gas pedal. As soon as I let off the gas the noise is gone.

According to the manual the high pitch sound is to let driver know that the pads are worn out but i checked and my pad still very thick after 15k miles.?

I have a 2013 Prius c #2. At 62 mph and faster there is a high pitch sound that gets louder the faster it goes. I have asked two other Prius c owner's and they don't hear it. You will need to roll up the windows and turn the radio off to hear this.

My 2013 GX makes this noise when I step on the gas padel when the speed is 70 mph or higher. It is not very loud but noticeable, even with the radio on. I noticed this these past two days on highway. There is no such sound during local drive or speed below 70. It sounds like it came from the engine compartment, but I am not 100% sure. Is this normal? Could it be from the wheels or chassis? My truck only got 1800 miles after 2 months driving.

It's been cold, but I've been driving. When I park and power down, I'm hearing a high-pitch sound...like a fàn...it lasts about 10 seconds.

When I test drive the PIP, I kept hearing a high frequency pitch noise whenever the car was accelerating. It almost sounds like when you lightly touch the trigger on a cordless drill. Sales guy and my wife couldn't hear it, but I do have extremely sensitive hearing.
A quick search didn't reveal anything, so I am wondering if this is a problem, or maybe part of the pedestrian warning system (although it happens at higher speeds as well).

I have 1,600 miles on my elantra and this sound just started. On initial starting, when the engine is cold, there's this loud low pitch then high pitch sound. It only lasts for 1.5 seconds but it's loud. What could it be?

My 2004 V8 Toureg has around 7K miles on it. The brakes are squeaking at a very high pitch. The same squeaky sound a bus makes when it stops. My dealership told me it is due to me not hitting my brakes hard enough. I have hit my brakes hard many times as of late and the squeaking continues loudly as folks will turn their heads. The dealership told me it is due to brake dust accumulation which if I wash the car they still squeak. Dealership also told me the VW regional field rep has told them that to rough up the brake pads which is a temporary fix. Dealership also stated if the brakes were replaced the brakes would start squeaking in a matter of a few months because this is how German cars behave. Not sure where to take this matter.
My other problems as of late are a bad power steering pump(replaced), bad suspension controller arms(new parts are ordered-kept hearing a popping sound when turning the tires and braking and grinding noise from the suspension), a bad keyless access module(replaced), steering column not centered(re-centered), wind noise from the rack ontop (basically to fix and probably only temporarily, unlocked them and then moved them forward a bit and then back to their original location- may have been loose as no more wind reverberation inside the car now), and rubbing from my driver side wiper. The brakes are the real thorn in my side at the moment due to other drivers hearing the noise while driving as they turn their heads. Very embarrassing especially coming from a new car!!

When driving in 3rd gear I can hear this quiet yet distinct high pitch whistling sound. It almost sounds kind of digital. You can hear it inthe other gears but just not as well and I know it's not the turbo or anything. What it may be and if it's normal?

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.

I have a 1995 Lexus ES300 with 130,000 miles on it. When I reverse, I get a low-pitch growling and as as soon as I apply the brakes by a high-pitch, ungodly screech. This noise is definitely coming from the rear wheel areas. I'm not sure which tire is the culprit (I hear both sides from while listening from both the inside and outside). It happens frequently but is particularly bad on rainy, snowy, misty, or high humidity days. Two years ago I replaced the pads and rotors. At this point, the pads look to have about 40% life on them yet. This problem started happening about a year ago.
My initial thoughts were that it was just rusting because of the frequency on high moisture days. But both noises are way too loud for that. My second speculation was that the emergency brake was catching, but after examining it I think not. I've taken the entire assembly (brakes, rotors calipers, and emergency brake) at each tire apart and looked for any obvious issues that look incorrect. No luck. I've also applied brake quiet with similar results. Now my thoughts are that the low pitch is the rotors being warped. But that doesn't explain the screech and why it only occurs in reverse.

New 2012 SE, I noticed a high pitch noise coming from the rear side of my car. The high pitched noise/whine happens as soon as the car is running, and continues until it is turned off. I can hear it every time when standing idle or at lower speed. So I brought it into the VW dealership, and my technician: "found noise described is the high pressure pump in the tank".
We tested another 2012 Passat SE and we found the exactly same(even louder) high pitched noise coming out from the high pressure pump. I was told by a service manager that it is a standard high pressure pump noise for 2012 Passat. Well I don't think that any high pitch ultra whine/noise should be a standard feature in any car...It is very,very annoying noise...

I'm on my 4th passat. Have an 08 Komfort. This by far is my most favorite of the 4 passats I've owned. This is the first VW I have had with satellite radio. I noticed not long after I got it that I could hear a high pitched beep that lasted maybe 3 or 4 seconds while I was listening to the satellite radio. It seemed to just happen at random times. I took it on a 500 mile trip a few weeks ago and I just figured out exactly when this happens............it happens when I hit the brakes while I am listening to sirius only. It doesn't happen while listening to FM or AM (I didn't try a CD). It doesn't do it every time, but at least 50% of the time. It almost always seems to happen if I have the cruise control on and I hit the brakes to disable it. I'm going to mention it to the dealer when I take it in for service.

2002 Passat wagon. I recently had my independent VW shop install new front and rear brake pads and rotors that I provided. The pads are PBR Axis Deluxe ceramic pads. Soon after, the front brakes started a high pitch squeal - mostly when cold or wet.
I took it back to the mechanic and he told me there is nothing he can do about it - I must have defective pads and that maybe they are covered under warranty, as they certainly need to be replaced, ...
This shocked me, especially the lack of customer service, but because I provided the pads I don't think I have much leverage with them other than not to do business with them again.
Is there any way to quiet a squeaking brake pad? Might the mechanic not done something he should have done to prevent squeaks?

I have a 2011 F-350 Diesel. It started making a strange whining sound when I start it in the morning. Very random and only does it when it's 0- -4 c. Took it to the dealership and they said its the cooler fan clutch. Got it replaced yesterday, and this morning I started it up and the whining sound was back. It also had a weird vibrating sound. What it could be?

Is it common for the exhaust to have a periodic high pitch tinny sound?
