Gti - Volkswagen :: 2008 - Constant Whistle Noise And The Pitch Changes With RPM?
Dec 1, 2011
I have a 2008 VW GTI which I love and have maintained pretty well. I unexpectedly got a job far away from home and couldn't move for two years (!) so right now it has about 70,000 miles on it (poor thing.) Luckily I now live about 5 miles away from work and it's finally getting a rest.
Long story short is that the oil was overfilled during a routine oil change. Foolish me didn't check the oil before driving away (i didn't do the change!) I got about a mile or two before the oil pressure light and beep told me to shut off the car, which I did immediately, and pulled into a shop literally a block away. They bled out some oil and checked a few things out and everything looked fine. But as soon as I left, and to this day (about a month later) I get a strange whistling noise when the car is cold and at low RPM. It's a constant noise and the pitch changes with the RPM (higher RPM, higher pitch) after warming up for a minute it goes away and doesn't come back until the next time I start the car.
My guess is that oil got somewhere it shouldn't have, like the turbo? And now something is leaking, like air? The car drives fine, no stutters or significant loss of power. Is there a way I can diagnose the issue myself before taking it in? Or should I leave it be and let the professionals take a look?

My 2003 Tacoma Pre-Runner V6 has started whistling at nearly a constant pitch which stops only when braking or after it has sat (not-running) for along period (hours). The whistle starts after the engine has been running for some time (10min +). I have been able to narrow down the whistle to the drivers side of the engine compartment but not any part in particular. I have checked the vacuum hose connected to the brake booster but is appears to be okay based on visual inspection. I have also briefly disconnected the vacuum hose (while pinching it shut) from the brake booster while the engine was running but the whistle persisted. When I stop the engine the whistle persists for about 20seconds before slowly fading and with my head under the hood I have heard a faint psst sound after it dies out. I have had not problems braking but do not want to start having braking issues. Any thoughts on troubleshooting this whistle?

2005 Malibu LS 3.5L (Epsilon Body) with rear disk brakes. Do the rear disk brake pads have the wear indicators just like the front pads?
Car started making an intermittent low pitch whistle noise (sounds like an old steam locomotive whistle, just really low muffled) but it only does it while turning sharply on right turns. It doesn't come on while turning left or driving straight.
At first I suspected the fuel pump but I'm not sure. I've owned the car since 2008 and never replaced the rear brakes, so it might be time!

For a while now, I have been hearing a very high pitch whistle noise from the turbo/exhaust area. Everybody told me it was an exhaust leak, but I never could pin point the leak. While I was under the truck last weekend I found the flex joint on the passenger side up pipe was broken a leaking.
I ordered a Dorman replacement pipe that comes with a new gasket and hardware.
I will be the first to admit, I am not a fan of Dorman parts... BUT, this pipe is really nice. It looks identical to the pipe being sold on Dieselsite.com, it doesn't have the scoop inside to direct exhaust gas to the EGR cooler and it comes with all the mounting hardware.

Once I got the turbo down pipe out of the way and soaked the bolts with penetrating oil, I had the broken up pipe off in 30 minutes.

Actually above + an interesting mystery.. Late last spring I began hearing a noise of constant pitch (sounding like someone sanding wood) when the engine was cold---Louder when it was colder/cooler. As the engine warmed up the noise went away. Throughout the summer,No Noise. n. Late summer broken water pump replaced along with hoses/belts. No noise until, temps in AM in the 40's.
Now that same damn noise is back.Only LOUDER! Same pattern>>as engine warms noise softens and goes away. My ear suggests noise is coming from the tensioner pulley (But, I've been fooled before)As to the question above, Do I tighten the belt on 'This vehicle' using the tensioner pulley or do I have to use the "Pry the Alternator forward" method.? One last thing, while the noise is occurring it does get louder with acceleration but is soon blocked out by normal engine noise.

My 2007 Prius Touring creates high pitch Squeak/Whistle sound while accelerating and braking, But if I put the car on neutral then the sound completely goes away. I have all the holes covered on the both side mirrors and this still occurs. The sound is constant for as long as I accelerate and Brake and the intensity varies with how hard I accelerate or brake, It also does that during regen braking when I leave the accelerator.

My girlfriend has a 2001 Ford Escape 3L, 6cyl. When accelerating there is a loud high pitch whistle/whirling sound. The sound varies with the amount of throttle you give it. More throttle = louder whine. Doesn't seem to do it when idling or coasting. What that could be? I'm about to remove the belt and take a look at the drive belt tensioner and other pulleys.
Just checked pulleys and tensioner and the tensioner seems fine, a/c pulley spins smooth and free no play, alternator spins smooth no play. The belt needs to be replaced. I wouldn't think this would cause such a load whistle under acceleration. I would expect it to do it all the time if it was the belt. I'm looking at the water pump pulley and belt too and they seem ok as well.

So I have a 1990 Ranger XLT 4x4, 2.9 v6. My issue is I am getting a loud constant whistle sound on the drivers side, just in front of the rear tire. It is not from the tire and it is a whistle not a whine. The truck is all stock nothing special. I do not have an exhaust anymore only a cat. Anyways the sound is constant an does not get louder or quieter while moving or in neutral it just stays the same. It just started in the last few days. Also the truck is a Manual.

I replaced the timing belt an waterpump at 262,000 miles and ever since the engine makes a loud low pitch noise that varies in pitch depending on the engine speed. I replaced the alternator and it didn't work. I don't know if the power steering pump, a/c compressor or something else is making this awful sound.

Whistle thru intake. I have a f150 2005 with a 5.4 and it likes to whistle when cold weather when I press the gas it goes away until it idles down?

2003 Jetta station wagon, disc brakes all around.
Recently changed all 4 pads + the rear rotors. about 2 weeks after this the car started making a horrible noise from the rear driver side wheel- like the tires were dragging metal.
We took off the wheel last night, replaced the caliper, and discovered one caliper bolt was missing. We think this caused the caliper to misplace itself and start riding the rotor. The caliper was also in pretty bad shape so we went ahead and replaced it because we had already bought the part.
Anyway, we put everything together, drove it last night a short distance, everything was fine.
Today after driving apx. 25 miles since the replacement, the car has started whistling. I'm not sure where the noise is coming from, but it only happens at higher speeds, and I don't know if turning affects it but it happens going straight. It is a cyclical type of sound and goes away when braking.
Note: when replacing the caliper, my dad did not use the little metal brackets because we couldn't figure out how to place them and didn't think we needed them. Would that cause this noise? Is that dangerous to do?
UPDATE: I've mislead you all! Upon further inspection the whistling noise is coming from the serpentine belt area. I had assumed that it was coming from the wheel because we had JUST messed with it, but I was wrong. Now I'm wondering what's going on with the belt!

My car occasionally makes a high pitched whine while driving it's very loud and very frustrating. I've come to the following conclusions: It only happens when the car is warm, it only happens at speeds above 40mph, it doesn't correspond to either accelerating or decelerating, it happens either way and in between. I've had people in the car while it's happened and the noise seems to come from the driver's side rear wheel. Sometimes it gets so loud and then gets even louder when I begin to apply the brakes, it's as if it starts screaming.
I've had mechanics take apart the complete brake system on every wheel and put them back together. They've put anti-squeal on the brakes to no avail. While driving the noise can come and go, with no apparent reason why. It happens in rain and on warm sunny days. Also, the noise seems to oscillate as if it is something that's spinning, I'd guess it's at approximately 160 beats per minute. This has been occurring for about a year, it was not this way when I got the car. No mechanics have ever found anything, but it's so loud! And so annoying and embarrassing. This can't be normal, what is it!?

Truck is a 2008 F150 5.4 4x4. I changed the spark plugs the other night for the second time. Everything went smoothly. Got the truck put back together and cranked it up afterwards to let it run. Truck ran great, but as the engine temp got up around 150 degrees, I started hearing a very loud ringing sound. I shut off the engine, double checked all connections, removed the belt to rule out accessory drive noise. No luck. The noise stays constant regardless of engine RPM, so I decided to drive it. I found the noise fades away under load, then returns as soon as I let off the throttle. I attached a GoPro to a cross member near the transmission after narrowing the noise down to the bell housing area.
Attached is a link to the video I made : 2008 F150 5.4 Noise - YouTube...

We've had a lot of rain here in pa lately and i hit a few big puddles the other day and now i have a growl slash wine in the front of my motor,now i narrowed it down to something driven by the bely because I removed the belt and no noise all pulleys feel good and smooth except the ac compressor if you spin it by hand it has a rough/dry feeling and sound to it but the noise doesn't change with the ac on or off its just constant grinding/whine. Replace the ac compressor pulley bearing that what I am thinking it is and don't really want to change out the whole compressor..

2008 Volkswagen Passat 2.0T... I am trying to figure out whats going on with my car for a few weeks now. I have a few things going on and I am not if they are related.
First off I am hearing a odd noise now and then from my engine area. Its so hard to explain, but its kind of like when a plastic bag gets stuck to your car, a fluttery higher pitched noise (and it lasts only a few seconds). It happens now on heavy acceleration (almost always), normal acceleration and even sometimes at start up. Its mostly random and started awhile back but I use to only hear the sound every couple weeks. Now its daily.
Related or not I also have noticed this really bad lag with heavier acceleration, after lagging it then down shifts VERY hard before taking off.

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.

Noticed yesterday a slight whistle from turbo in my 108,000 mile MY2008 3.0tdi ( the engine is new at 90k miles, but the turbo was transferred over).
Its barely audible, a gentle whistle from about 1500 to 1800 rpm on moderate acceleration. It's then lost in general engine/ road noise. Car drives smoothly and pulls as normal.
Only noticeable on quite road surfaces, radio off, etc, and no more than I recall as standard from earlier turbo diesel Audi & BMW cars from the 1990's.
A quick on-line search indicates carbon build-up can be an issue? In the past few years my mileage has dropped way down to maybe 9k miles per year, mostly shorter trips & not as much higher speed motorway as previously.
If this is the potential end in sight for the turbo, can the unit be refurbished.

Yup, my truck randomly whistles while driving in cold temperatures. Its not life threatening or damaging to the truck, its been doing it for a few months not that its been getting below freezing. Its just REALLY annoying. I can even hear it over my radio at times, so its pretty dang loud outside of the truck. The noise originates from somewhere under the hood in the engine compartment.
Won't do it at lower speeds, usually on the freeway. Motors at about 2k rpm and im going roughly 65-70. Change the rpm when it whistles and it goes away. happens randomly from 50mph to 70mph engine speed from 1.8k to 2.5k rpm. I've tried to find it but can't find a darn thing since it won't make the noise while sitting in my driveway. What it might be?

I have a 2002 Corolla with about 180,000 miles that has been well maintained, but I know very little about cars.
Over the past months, I've noticed the engine noise on acceleration sounds a bit louder than I would expect it to, and it seems to be getting louder over time. It's slow changing, so I'm a little unsure. And occasionally I wonder if I don't hear a sound that shouldn't be there, though I couldn't describe it yet. Mechanic said the acceleration noise is normal at start-up for older cars until they get warm, but this happens even after I've been driving a while. Worth the $100 for an engine checkup?
Also, the A/C doesn't seem to be the strongest and has a high pitch noise when I run it. Normal?
