Passat (B7) :: Whining Sound That Increases With RPMs After Stereo Replaced
Dec 6, 2011
After having the stereo replaced over the weekend, our car has now developed a whining sound that increases with rpm's. My wife didn't notice the whining sound until today, which means the car was driven at least around 100 miles between the installation and this morning when she noticed it after leaving the house.
It sounds the same as I've heard before when the alternator makes a noise through the speakers, however the sound doesn't sound as though it's coming through the speakers. With the Pioneer unit that we have, you can turn off the audio source, but I don't really see a way to completely turn off the unit.
I went down with the thought of removing the fuse for the audio system, however the manual states that at the time of writing, they couldn't document all of the fuse mappings and to refer to the dealer.
We have an appointment in the morning to have the dealer check out the noise, but if it ends up being the stereo install that caused the problem, I'm thinking they may charge me for the service visit.
Which fuse controls the stereo so that I can pull that to see if the noise stops?

I have a problem with my 2006 Sante Fe. When driving (at all speeds) my SF has developed a "cyclical", repetitive whining sound in the engine compartment that directly corresponds with the speed of the car. The "revolutions" of the sound are slow at slow speeds and very high pitched and fast at high speeds.
It happens at all speeds, with or without throttle being applied. I do NOT hear it when the car is in park or in neutral and I rev the engine so it has something to do with the rotations of the wheels/axles/drive shaft/gears or something that rotates in synch with how fast the car is going. I still hear it when coasting.
We recently put on new tires a few months back and I thought maybe it was just the sound of the new tread on the road but now I am almost positive this sound is coming from somewhere in the engine compartment. It is possible that it is coming from under the car but the problem is a can't confirm that because I only hear the sound when the car is moving. So far, it's just an annoying sound, it does not affect the performance of the car.

My GT is very quiet when running and I like that. However, the AC system seems noisy when it is on. When I turn on the fan and heater, I hear a distinct whining sound that increases in frequency as I increase speed. When I turn the fan off, the car is whisper quiet. Also, when I turn the AC on, I can hear what sounds like coolant circulating through the system. At first it sounded like it was coming from the glove compartment and I thought it might be associated with the glove-compartment cooling feature, but I don't believe it is. The noise is not unbearable but it is noticeable and distracting to me.
Is this a noisy climate-control system or is this something unique to my car.

2 days ago in order to get home I had to attempt to drive through a rather large puddle. Never stalled or anything but the front was fairly submerged, not enough to stall but enough. Now I am getting a god awful noise from the front, and I think its the ac. I noticed the noise increases with rpm's. Can I just remove the belt so that I can still drive the car without the AC?

Experience a hissing sound from stereo, specifically mark levinson. The hissing sounds occur from certain songs and when the engineer rpms are around 4500.

Ok, so there's a whining sound that is going along with my RPMs, that is coming from the area of my belt, obviously i think its the belt. I am also leaking a little anti freeze. What this could be.

After 10-15 minutes of driving my car tonight I noticed a knocking sound and maybe a sort of whining sound that corresponded in speed/pitch to the RPMs. No warning lights, codes, temperature gauge ok, performance was fine.
I looked under the hood and I'm pretty sure it's coming from the left side of the engine (where all of the belts are). I didn't have time to isolate it further.
After 2 hours I started it up again and the noise was gone. As I drove I listened closely and after about 10 minutes I started hearing it again. It was quieter than before, but I assume it would have continued to get louder had I not arrived at home and turned off the car.

Over the past 2 weeks, started having a whining noise from front end. It seems to be coming from the front passenger side. The noise starts at around 30 mph and increases with speed. Very noticeable at highway speed. Sounded a bit like tire noise. I did rotate the tires, front to back, but noise persists from the front.

I am looking over a 1998 Ford Ranger. Very low miles for its age (67,000) and kept in very good shape. When I took it for a drive, I noted an issue.
- there's a whining sound in first gear and reverse that varies according to the engine RPMs. I thought it might be the power steering pump, as that whined when I turned the wheel.
However, the noise went away when I shifted to the higher gears. Been a while since I drove a stick - my Bug back in 2003, IIRC.
What I might be getting into? I really like this machine, aside from that issue, and I would like to nail the problem down ASAP...

My 2009 , 1.8 Corolla gets terrible gas mileage. 23 city (lowest was 12), best ever was 30 highway. I have approx 14K on the odo because the MPG makes me want to leave at home.
The MPG has been verified in writing by 2 different dealers, so I do not consider myself the problem.I drive conservatively and calculate MPG based on actual miles / gallons.Toyota Corp did not bother to fix this issue.It has been serviced regularly and had whatever fixes Toyota offered.
What I think is causing my terrible mileage is some glitch in an engine sensor that causes it to rev from 900 to 1100 RPM when I take my foot off the accelerator and attempt to coast. The revs go down when I press the brake. This happens constantly, especially at around 25 MPH. If I do not brake, the car will pull for a while without slowing down like normal cars.
I showed my Toyota dealers but they all said nothing is wrong. My Corolla even went up a slight hill without my foot near the accelerator. One tech told me the Corolla is burning off extra fuel, but my car will pull itself for over 1/2 mile, too much time for "burning"
Something IS wrong. I have driven dozens of vehicles and never had one jump like this. Where to start diagnosing?

I have a 2000 Neon with about 170K miles on it. with in the last 2 weeks it has been having a problem with acceleration. When i start to drive the RPMs will get up to 4 before it will start to move. Also when i am drive and need to pick up speed the RPMs will also go up to about 4 before it starts to pick up speed, but will drop back down when the speed goes up. I have found a little oil in the spark plug tubes and will be changing the seals out, and I have cleaned to MAP sensor as will. What is going on with my acceleration.

Does your car make an annoying whining sound when accelerating? My engine wines almost as if it had a S/C. You can only hear it when you rev under 2200rpm.

This morning I just began noticing a low pitched whining sound when I accelerate at low speeds (below 30 mph). The sound seems to disappear at higher speeds for some reason. It bothered me so much that I arranged to have all the timing belt service done....I have been putting this off....84K miles now on a V6 Passat. I'm thinking it is the water pump noise, but I am not an expert on cars like most of you are. What all SHOULD be done when you change the timing belt?

My 2004 V6 has about 21,000 miles, and has run perfectly from day one. However, the last few days I've noticed a whining sound which I think is from the transmission. when I first start out, at very low speeds. I don't think it occurs at higher speeds, but I'm not sure because of road and engine noise. The noise doesn't really bother me--goes away quickly. But is this something I need to have the dealer look at? It's still under warranty.

My 99B5 1.8T Auto is making some weird sounds... I heard that it is either a serious issue or just a lack of fluids. Sad to say that the same sound was coming from my Toyota Highlander right before the transmission died on it (I know, completely different vehicle; but same sound). What I can/should do about it. The sound starts in 1st, loudest in 2nd, and begins to leave around mid 3rd gear. (Again, same as the Highlander), I don't want this car to die too.

I have a 3.6 4Mo always maintained on time and everything but recently, in the middle of 1000 and 2000 rpm's, it makes this weird gurgling sound, ONLY in that range, mostly around 1500. But after i accelerate out of that rpm range, it goes away and sounds perfect, immediately, like you changed a channel on TV.

This is a 2002 Toyota Camry 4cyl with 249157 miles. I drove it 140 miles to work, noticed no issues, parked it, and got back in after 10 hours. On the way back I noticed a noise that got louder the faster I went. It is independent of the engine revolutions (I put the car in neutral and "coasted"). The noise is completely dependent on the speed of my forward movement.
So I put the car up and in gear and around 25/30 mph, the sound shows up and gets worse as the speed increases. It does not get worse in turns. And it is very consistent- not clunking or clicking, just a steady sounds almost like strong wind over an object. I replaced the wheel bearings in both front wheel assemblies about a year and a half ago.

I was driving down the road tonight and have been hearing a hissing sound when accelerating and when I went out to get it audio of it to send to the VW dealer, I heard a loud noise, and now it sounds like I don't have an exhaust, the rpms aren't raising no where near what they should be, and have a gaseous smell.

So I have a 2014 VW GTI 4DR 6speed with 25,000 miles on her now and I am getting this weird noise from what i believe is the front end right wheel?
The noise is similar to a rubbing / humming sound that occurs below 10MPH and then increases with repetition at say above 60MPH. I notice a little harder of a rubbing when wheel is turned at say when i pull out from a stop sign!
ALL that i have done was put on hubcentric spacers and that i pulled off to see if noise stopped but it didn't! Could the supplied bolts be to long? I had removed dust caps on rear for clean fitment and sanded any imperfections on all hubs.
The noise isn't loud at all but is definitely noticeable with radio off and windows up!
Could this be a wheel balance issue? Tie rod or arm? Bent RIM?

I have a 2007 Ford Fusion SE 2.3L 4 cylinder. It has approximately 94,000 miles on it. I purchased new Sumitomo tires with a 100,000 mile warranty in February of this year. They were balanced and aligned at the time of install. So far they have been very smooth and quiet with great grip. About 2 months ago I started hearing a noise that sounds like uneven tire wear, a sort of rhythmic rubbing or wobble sound that increases in frequency as the speed increases. It is most noticeable at speeds between 30 and 50mph. I rotate the tires every other other change (at least twice a year) and had the alignment done again in late October. I am hoping that there is nothing wrong with my virtually brand new tires. Is there anything else it could likely be?

The car is a 1997 pontiac sunfire 4 cyl 2.4L.When the car is turned on it makes a sound like the one in the mp3 file that I've attached. Some other symptoms I've noticed is a very slight loss of power while accelerating, and whenever I pull up to a stop and the engine gets into the idle rpm range (800-1000) the oil light comes on and the rpm dips to about 400 and sometimes the engine dies. The engine is also running very very hot, although I haven't driven the car in about 2 months and it's 100 degrees outside, not sure if that's related.
What I have tried so far is replacing the oil and filter, and adding 2/5 a pint of seafoam engine additive for 4 quarts of oil as per the instructions on the bottle. I did this because I suspected it was a stuck lifter, but after driving it for 30 miles with no improvement I'm starting to think otherwise.
As some of you may know I'm not entirely mechanically inclined and that's why I'm here, sometimes I get posts from people who insist I shouldn't be anywhere near an engine but let's try to keep those negative posts off my thread.
