Passat (B6) :: Under-carriage Whirring Noise Exactly Proportional To Speed
May 15, 2007
I'm bringing my 6MT 2.0T in tomorrow, for 10K service, installation of the Euro-cupholder and to have them investigate a sound I first noticed last week. For lack of a better description, it's a "whirring" noise that is exactly proportional to speed (higher pitched at higher speeds). I'm guessing that it's either related to the clutch or the drive shaft.
I can't hear it well with the windows open. It seems to emanate from under the stick-shift. It is audible either in gear or not. (And it seems to be getting slightly worse each day).....

Is it my wheel bearing, rotors or brake pads?
How do I describe it... well it has this squealing noise and it's proportional to my speed.
Heard this while I had my windows rolled down.

I have a 1999 Subaru Legacy 2.5 GT and I get a whining noise that is directly proportional to road speed when I drive. The noise is ONLY heard when the car is moving and your foot is on the gas. The second you lift your foot to coast the whining stops. If you are stopped, no whine. If you change gears, the frequency of the whine doesn't change. Turning the wheel left/right doesn't change anything. If it sounds like anything I've heard, it sounds like a dry differential. I've checked the front diff fluid level (the whine comes from the front) and the fluid level is full.

Have replaced BOTH half axles. Clicking sound present when driving - does NOT change when turning right or left. Seems slightly affected by acceleration/deceleration - makes clicking slightly louder/quieter. Clicking is DIRECTLY proportional to speed - slows down until car stops. Transmission works fine, fluid level is correct. New trans fluid and filter. What the heck could this be? Wheel bearings seem solid - jack up car and try to wiggle wheel - solid as a rock both right and left sides. WHAT ELSE COULD THIS BE???

2011 Elantra GL.
Recently, we noticed a ticking sound coming from under the hood (the rate of "ticking" was proportional to the engine speed). We took the vehicle in to the local Hyundai dealership and didn't hear anything from them until 6 hours later. The news was interesting; they were going to perform a full engine replacement after consulting with Hyundai Canada. In my experience, a resolution of this large of a magnitude usually takes weeks of kicking and screaming for any large corporation to comply, however it seems like a pretty hasty conclusion, indicating to me that Hyundai might be already aware of such an issue...
So here is my question. We requested photos from the dealership, and they were able to send two pictures of one of the camshafts (not sure if it's the intake or exhaust cams), but the only thing that I could notice was some slight abrasion/wear; certainly not enough for me to ever come to the conclusion that a full engine swap was necessary. I've attached the pictures.

I have a 2003 Acura TL with ~200k miles and an automatic transmission. Recently, I noticed a whirring noise at low speeds <20mph, but only while coasting. The noise goes away if I hit the brakes or if I hit the gas, even if I manage to maintain the speed below 20mph. What this could be?

High pitched whirring noise when the climate control fan (compressor?) is running at low speeds. It doesn't seem to matter if the air is on or not. I'd like to know what it cost to fix and if it is covered under most extended warranties.

I have a new 2012 Chevy Cruze with 10,000 miles on it. Chevy has issued service bulletins citing a problem that they can't seem to diagnose or repair (yet) and my car has the problem. They tell me their engineers are working on it. After the car is a little warm, when I apply the break there is a loud squeaking or whirring noise which pulsates at the speed of the tires (in other words, as I slow down, the intervals between each sound gets longer and longer). I suspect it is coming from the back. First they thought it was sticking calipers until they realized that I have drum brakes on the rear. It is loud enough that the only way no to hear this grating noise is to blast the radio.

Middle of May, I went to Boston. On the way there, I started to notice a slight whirring noise that was only present when I gently feathered the gas to maintain highway speed. If I were to apply any more throttle, the noise would go away, and if I were to pull my foot away and allow engine braking, it would also disappear.
So I did my best to finish the trip to and from Boston adjusting my driving to avoid the noise. Once I came home, I researched and thought the noise might have been my wheel bearings (I had just replaced lower control arms, lower ball joints, inner and outer tie rods prior to leaving for Boston). I also had a shop install my upper strut mount bearings and bushings simultaneously with the wheel bearings.
Since then, the problem still continues. It has grown louder, but still occurs under the same situations. I've focused more on it and here are the conditions under which it occurs:
1. Car must be warmed up. Starting it up cold and allowing SAI to run then driving, car is fine, no sounds. Usually takes 20-25 mins of driving to get it to start making noise.
2. Car still only makes the noise when the gas is being feathered (ie barely pressing it enough to give it any sort of throttle. It does also make the noise between shifts when reengaging the gear and applying gas, as the throttle pedal passes the point of throttle off to throttle on.
3. I'm hearing more noise now during engine braking than I had been previously. Could be related?

I have a 2004 F-150 SCrew Lariat 4X4 with 80K miles. Over the past month or so, every once in awhile there would be a loud metallic "clacking" sound (kind of like sticking a peice of aluminum in a bike's spokes) that would start at higher speeds and would turn into a low pitched whirring gear sound as I slowed down and eventually there would be a thud followed by a sensation of running over a small bump and the noise would be gone. Kind of confusing I know, but that is the best way to describe it. My gut feeling is a wheel bearing or transmission problem....

There's something that sounds like an electric motor whirring for a few seconds when I open the door on my 2009 Passat Wagon after it's sat overnight. (I'm not sure if it does it other times as well, I've not really noticed). It's not really annoying, and I don't think anything is broken or malfunctioning. I'm just curious what that motor is doing.

I need to diagnose an issue I've had with my 2007 Prius with 79,000 miles on it. Several months ago I noticed a distinctive whining/humming noise coming somewhere from the engine compartment of the car while driving. The noise may be present at lower speeds, but the volume of the noise appears to increase proportionately with my acceleration and as such is most noticeable at highway speeds of 50 - 70 miles per hour. As I accelerate faster, the noise level seems to increase. If I take my foot off the gas and coast, decreasing speed, the whining noise gets lower in volume. I believe I first noticed this noise about 6 months ago, but wasn't more proactive about it like I normally would be because at first the noise didn't seem overly loud and my extended warranty unfortunately was up once I hit 77,000 miles. Now 6 months after I first noticed the noise, I believe it's definitely louder than it was when I first heard it, so much so that I can pick it out over the radio being on at a decent volume.
After checking some forums I thought the culprit might be a wheel bearing. I took it into a local Midas shop at they informed me that my passenger-side front wheel bearing was actually breaking apart in pieces. Obviously I had that wheel bearing replaced but I was also hoping this was the source of the whining noise. Unfortunately that wasn't the case as driving it home the noise was still present. They also said the tires were not balanced properly (from my Toyota Dealership no less when I had them install new tires) so I had the tires rebalanced as well. They did take the car for a test drive but probably stop looking for issues with the car as soon as they saw the wheel bearing in that condition. Also that shop does not specialize in Prius' or hybrids so they might not be able to notice the noise that shouldn't be there like I can.
Other than wheel bearings, where this noise could be coming from. Some posts on here possibly pointed to the ICE water pump or transaxle fluid (which as far as I know has never been replaced since I bought the car new).

I just purchased my vw used with 28,000 miles on it. After its been parked for a while, I open the drivers side door and an audible whirring noise coming from somewhere in the car goes off, what is this noise coming from?

I have a 2000 VW Passat 1.8T Automatic. During a cold start, I notice a rather loud noise like a motor whirring that lasts for approximately 30 seconds. My RPMs also run about 200 higher than idle during this time. After the 30 secs the noise goes away (sounds like this motor powers down) and the RPMs return to normal.
It doesn't happen every time I start the car, just when it has been sitting for more than 4-5 hours or overnight. What this is and what if anything I should do?

My 1992 Buck Century sometimes makes a whirring sound when I reach a speed of 45MPH or more. Sometimes it sounds steady or sometimes rythmic like "whir, whir, whir or whoop, whoop, whoop. It doesn't do it while standing still, so I know it's not the engine. It's strickly a motion noise. Is it the brakes or wheel bearings? Transmission problem?

What to use to clean your undercarriage/wheel wells of your T-reg? I use a Natural Orange Base cleaner with some scrubbing, then Black Magic Tire Wet Foam on my MK3 GTI, just want to make sure I don't do anything wrong or damage anything, I know it's suppose to be able handle submersions up to 22"..

Our V6 just turned 40k and it's developed some interesting sounds. First of all, from time to time at highway speed a whirring/whinning sound has developed. I was driving down the road the other night, no rain, about 60 degrees temp outside, and between 50 and 80 mph this noise seemed constant. I turned off the radio, turned off the climate control and the problem still existed.
It *sounds* like a drive train noise (my old jeep would make a sound when it was in a low gear that is similar). Second, also intermittent, a clicking relay from inside the dash on the drivers side. The frequency and rate are inconsistent and I can't correlate it to anything happening while driving.. just highway driving.

My ES350 is always parked in my garage. One afternoon, I went into the garage to get something and I heard a humming sound coming from the car. It was very hard to identify where it was coming from. It sounded like a low horsepower compressor of some sort. I put my ear next to the rear wheel on the drivers side as this was the area the noise appeared to be coming from.
This is the second time I've experienced this happening. A couple things to note:
1. The car had not been operational for at least 8 hours.
2. There was no indicator lights on the dashboard flashing.
3. All doors were closed.
4. It seems to happen intermittently and I can't replicate on my own.

Entrance way to my office parking garage is VERY steep. Aside from careful entry/exit is there a protective shield/device that I can apply to prevent paint damage to under carriage of front bumper?

OK, so I'm looking for a little insight before I head back to the dealer. Currently running an H&R Cup Kit (about 6,000 Mile) and been happy BUT:
1. @ install I replaced F&R Upper Strut Bearings & alignment by dealer, also swapped to F&K Shorter Front Sway Bar Links.
2. Front Control Arm Bushings replaced under warranty by dealer about 2,000 Miles after Cup Kit Install.
3. Front Upper Strut Bearings replaced under warranty about 4,000 Mile after suspension install due to a slight clicking noise at low speeds when turning hard to the Left (so only 2,000 Miles on the last set and they were replaced).
4. Installed 26mm H&R Rear Sway Bar about 1,000 Miles ago on softest setting.
So where I am at today is the low speed front end noise is back and worse, I now have noise no matter the degree of the turn. Also sounds like sub-frame is lose when hitting speed bump etc (first time on this VW but been through it with the last Audi). My question is what are different peoples opinions as I think I'm overlooking something before it goes back to the dealer again. Sounds like the front spring is binding a bit as I can hear the clank as the tension releases but this can also be the front sway bar.

When I drive over a bump or the car goes over a dip at speed, there is clunking sound from the front end. It seems to be much more noticeable in this cold weather, hence my current concern. I have not looked into it at all. I live on a bumpy dirt road, so the front end gets a workout.
The car has 39,800 miles. So the 40k is almost here, and the 4 years is almost here as well so I cannot just not drive the car for a while.
But if I can get a common problem fixed under warranty, I will take the time tomorrow to deal with this. The other weird thing in this cold snap is that the VW never seems to get to 190 deg, like it usually does (middle of temp gauge), it will be a few notches below. Normal situation? It will go back to 190 if I turn off the heat and drive a bit harder, but with the heat blasting (baby in car) and very mellow driving, it doesn't quite make it...
