Golf/GTI VI :: Resonating Humming When Rev At High RPMs
Nov 25, 2013
I installed a CAI (CTS Motorsports) and I'm hearing some sort of resonating humming while driving. I also installed a 3'' turbo back exhaust (SPM) and did APR stage 2 tuning. I did not do everything at once, the CAI was installed 3 weeks prior to any other install on my car. I've been hearing that annoying hum ever since I installed the CAI. The humming doesn't happen when drive normally, shift and slowly increase the throttle, but when I stomp on the gas I hear it every gear shift around 3000 to 5000 rpm. When I mash on the gas and shift, it hums only for a short period of time until i shift again. I don't think its a high speed hum issue. I can easily do 120 and not hear a thing, but when i rev at high rpm's I hear that resonating hum.

B6 manual, after 20k miles with Dunlop Sport Maxx 235-40-18 tires (still pleny of tread left, even on fronts) a moderately loud humming noise has developed, loudest at 35 mph but even heard at 10mph, with an irritating resonance of subwoofer-type. Noise changes somewhat with road surface, but not much. Not related to engine speed, gearbox, or radio. My next step will be to swap wheels.
For now, any thoughts as to the cause?

I own a 2007 Prius Touring w/120kish miles. We are currently experiencing a huge booming resonance at idle and low RPMs. The noise isn't subtle, almost sounds like we're in a Huey with the doors open. Here's what I believe I know:
- No DTC's are being thrown
- ICE seems as smooth as ever
- No apparent changes in fuel economy
- Plugs were replaced 40k ago and coil ignitors are original--not running rough or missing though
- Visual inspection of exhaust shows no leaks or contact with body
- Motor mounts pass the test I looked up [in drive/reverse, depress brake, watch unusual engine displacement]
- Noise is not vehicle speed related, only engine speed coupled--probably between 1K and 1.8k rpm
I'm sure I'm leaving something out but aside from messing with the coils or plugs I've looked at everything I can think of. I haven;t gone to the dealer yet. Lot's of reading searching have only revealed CV issues.

I have a 97 3.5. A few years ago something in the drive train started vibrating/resonating strongly when the engine RPM's reach about 1800-2000. I can feel it most in the gas pedal but it also resonates through the dashboard and sometimes makes the dash cover buzz. It didn't start out faint and get progressively worse, just started one day and has been there ever since and hasn't really gotten worse. Actually started after replacing my plugs, wires, intake gaskets, and valve cover gaskets. I originally thought engine, then I thought maybe it's in tranny, but it's worse when a/c is on although compressor is quiet and works great.
More info: has 198k, runs like a champ, no hesitation; tranny replaced @ 104K

My girlfriend has a 2008 with around 120k miles on it. It's been pretty flawless but yesterday the RPMs started surging while idle and made kind of a high pitch humming noise when accelerating.
Today on her way to work she said the radio was going in and out, the battery light lit up and then the rest of the dash lights came on, and the speedometer stopped working.
What could be the problem? Could it just be the battery?

I have 2003 f250 6.0, had the turbo rebuilt and I put it back in, my turbo is whistling but I'm also getting a humming noise kinda sounds like a when u down shift at high rpm's idk what's going on, I try and power break as well to build up boost and the tires do not even spin...

2003 jetta gls 1.8t 5spd - gts stage 1 tune(gonzo stage 2)
tt 2-1/2" downpipe with high flow cat
turbo smart splitter valve(set to divert only)
turbo inlet pipe
homemade intake with k&n filter
stock n75 valve (f)
So in first through 3rd gear my car gets 20psi of boost then at 3,500 ish rpm smoothly starts to lower down to 15psi. but in forth and 5th gear the boost drops faster, enough so the diverter valve actually opens. then the boost will bounce up and down, around 15psi. the car still accelerates but with obvious power loss.
Is my diverter valve not "firm" enough? it is adjustable, so I've tightened it as much as it can. it doesn't seem to change anything. it came with spring spacers to make it tighter, but I haven't tried that yet.
Is it something with the tune? not enough fuel, need bigger injectors? The problem is only at about 100mph, so its not a big deal. I would like to get it straightened out if possible.

I took ownerhip of my R32 last week, there are a couple of things that I have noticed that I need to sort out.
1. There is a resonating sound at low speed from the rear boot trim, right where the rear windscreen wiper is, I can also make it happen when the boot is open by flicking the trim, is it loose, or what, is this a common problem..? Do I need to remove the trim and fix something...?
2. There is a black box under the driver seat with some electronics in it, I am dammned if I can get the lid to go back on properly, I have had a look and can't see any plastic Tabs broken, but it won't go back on properly, just keeps falling off...I have long legs so my seat is nearly as far back as it will go for me to drive, so this box is exposed, I need to get this on properly.
3. The cupholder thing down between the driver and passenger seat, there is a sliding lid on it, it is stuck half open (or closed..!?) and I can't get it open or closed, how th heck do I get at this to fix it...?
4. I will be looking what version Firmware the RNS 510 / MFD2 is, I am also looking for iphone integration, I have blue tooth for calls, and Sat Nav and the bigger display MFD....and would like to control the phone / tunes with the steering wheel, and see the track info in the MFD.

So I've been having this issue for a while and I think I know what it is, just wanting to confirm it is the problem before I go fixing it. My car idles at high RPM's, at around 1-2k when I am sitting at a stop sign or stop light. I replaced the MAF sensor but that wasn't the issue. I assume that it is the throttle body or the sensor.
Also, I came out the other day to park my car in the garage and I saw a huge puddle of water where the passenger puts his/her feet. It was all in the carpet and I just dried it up. It was raining out but I don't think I have a leak or anything. I was told it might be my heater core that went out and that the AC is the problem.

I don't own a VW, but my friend does, and she knows absolutely nothing about cars. She drove me home from a friend's house today, and I noticed her car was sitting at insanely high RPMs, even though we were only going like 60-65. The car was ranging from like 4500-5200rpms the entire way home, and the engine sounded like a lawn mower.
Don't know many details on the exact model of 2002 jetta it is (I'm a subaru guy) but it's an Auto. I was convinced she had it in 3rd the entire way instead of drive. I asked and she said it was in drive, but I was sitting in the back so I couldn't quite tell. Not sure how being in 3rd works on an automatic, but she could still come to a full stop. The car was pretty much constantly sitting at above 3k whenever it wasn't at a full stop though. Like, after letting of the brake at a stop light, and pressing the gas, it'd pretty much immediately flick up to 3k and never go below.
So, not sure if this is normal for these cars, but I thought it'd be worth asking since it would suck for her if this could have been fixed earlier. My subaru sits at 3k when I hit 60, and only hits 4k if I'm going like 80, so I just thought this seemed pretty weird.

I can smell the exhaust inside the cockpit when accelerating and high RPMs, but in nothing in normal driving. I checked the pipes for leaking but all is fine.
My friend suggested to remove the catalytic converters that might be blocked. the car Mileage is now 145000 KM....

My 2005 Jetta gli 220k miles just spurred going down the road now every time I accelerate and get into high Rpms the Ac vents start to blow harder and feels like loss of power. It's fines at idle and first gear but 2nd and up its does it I'm stumped....

I have a golf mk4 1.8T AGU, about one week after i had my k04-023 turbo on and all the Stuff that comes along it started "stall" (don't know if its the right word??) in the High gears, most 5th gear but it first start doing it when i hit boost (3000rpm)
I runs on Stock n75 valve.. I though i could be a boost problem, maybe the Stock system cant handle it? I did install a boost gauge to see if it was the was the problem, and it dont Seem like it. In first it runs from 1.4 bar and drops to 1.2. Same in second and third. But in 4 and 5th it goes to 1.7 bar and drops to 1.4.. I did wonder it maybe the n75 valve cant handle 1.7 bar??

So it sounds like a whine at low RPMs, but once I get going it goes away. Popped the hood while she was running and took the filter housing loose and you can hear it through the intake... It's all stock....

I recently noticed my brand new truck with 5k miles has been making a humming /vibrating noise when shifting and when RpMs are above 2k. What this could be? It's a 2014 F150 stx 3.7 ....

I put a link below on the video that I made. But when I come across 1,000 RPMs weather I turn, go straight, left or right it makes this noise like a humming or rubbing noise. I took it to the dealership and they fed me crap saying when it gets worse or when it happens every time brig it back.

I don't think this link is working I'm trying to figure out this iPhone. Search my YouTube channel Kill3rcr3w that's the channel I just uploaded it

When I remove my foot from the accelerator, my '86 Land Cruiser makes a noticeable and resonating vibration. It generally occurs at deceleration from about 60-65mph or when I'm going down a hill, when I habitually feather the accelerator to regulate my speed regardless of the slope, and rattles the whole truck to the extent I can feel it through the back of the driver's seat. The truck has always had a certain looseness or slop in the driveline; if I'm not careful to feather the clutch release, the truck starts off in a herky-jerky motion. Yesterday, I was nosing around under the truck attempting to discover the source of the vibration. When I grasped the rear drive shaft (it has a second drive shaft for the front wheels), there is noticeable free-play of about 5-10 degrees in the shaft rotation. Is this normal for this truck?

Just picked up my car from the shop last night. Had a full tune up, air filter replaced, radiator upper hose replaced (was leaking), transmission service and an oil change. When I picked up the car at night I heard that it sounded a little off when starting but I was so excited to have it back that I drove it home. Once I was on the freeway, no weird noises and it drove perfectly fine. This morning when I started it up again the sound was there again. I can only explain it as a sort of high pitched humming. I pulled away from the curb and it made more noise - I heard that sound once when I needed power steering fluid. I put the car in park and popped the hood. Power steering fluid was full. My mom suggested I restart the car so she could hear the sound. This time when I started the car it sounded fine. Typical.
I drove it to work and it drove fine and never made that noise again.
(car is a VW Passat 01')

I noticed it a little after driving for days on very snowy/slushy/gritty roads where I had to plow some parking spots with my little 2013 C3. Tonight I was driving into Vancouver and back at 100+kph and noticed like a whirring sound or like a higher pitched humming sound possibly from drivers side front tire?? A little vibration felt through the wheel.

My girls family has had an 08 elantra 2.0 new since 2008 and I've been doing the work. I recently did the timing belt ( July) with beck arnley oem parts. 65000 miles. I replaced belt, idler, and tensioner.
Right after I did it there was a mild hum at idle. It somewhat did this before the belt so I assumed it was just the new belt in plus the very mild hum it already had.
Recently it is humming very loud and high Pitched. It gets louder with higher rpm. If I take the cover of and move the needle on the tensioner while it's running it quiets down a little but it's an auto tensioner and doesn't stay right where it needs to be AND even when it is at the ideal spot it still hums.

I have a 4 cylinder 2012 Toyota Camry SE. It is 3 months old and has 2,300 miles.
My husband and I notice a high pitch humming noise that happens mainly on the freeway, when you get over 45 mph. We tried ruling out different things like, bluetooth, radio, air conditioner, wind noise etc. We realized that the noise happens with you push on the accelerator pedal. If you hold the pedal to maintain speed, it does not happen. Only when you push the accelerator pedal. The noise was more noticeable when I drove it up in the mountains and had to push on the accelerator pedal off and on to maneuver turns and up hills.
I figure that we can bring it up to our dealer in October at our 5,000 mile service.
