Passat (B6) :: Resonating Loud Humming Noise
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?
Prius (2004-09) :: Booming Resonating Noise In Cabin At Idle And Low RPMs
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.
Intrepid :: Drive Train Vibrating / Resonating Strongly When Engine RPMs Reach About 1800 - 2000
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
Lexus GX 2004-09 :: RPMs Started Surging While Idle And High Pitch Humming Noise When Accelerating
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?
Ford 6.0L Power Stroke Diesel :: Turbo Is Whistling / Also Getting Humming Noise When Downshift At High RPMs
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...
View 4 RepliesGolf IV / Jetta IV :: Losing Boost / Power At High RPMs In High Gear
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.
Golf V R32 :: Resonating Sound At Low Speed From Rear Boot Trim
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.
Golf IV R32 :: Car Idles At High RPMs
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.
Golf IV / Jetta IV :: 2002 Running At Insanely High RPMs On The Highway
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.
Golf V R32 :: Smelling Exhaust Inside Cabin When Accelerating And High RPMs

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??

Toyota - Landcruiser :: 1986 - Resonating Vibration When Decelerate From About 60 To 65 Mph
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?
View 6 RepliesPassat - Volkswagen :: 2001 - High Pitched Humming On Start Up
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.

Prius C :: 2013 - Whirring / Humming Noise At High Speeds
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.
View 7 RepliesElantra HD (2006-10) :: High Pitch Humming After Timing Belt Changes
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.
