Golf IV / Jetta IV :: 1.8t Turbo - Hissing Sound When Accelerating

There's this 1.8t gti I'm buying this week from a family member and we've been trying to solve an issue that we ran into. When accelerating the car there is a hissing noise, safe to say that it is air. Then when accelerating a little harder and you feel the turbo pulling you everything seems fine. But a second or so after , the turbo dies off and so does the hissing noise. Then I can let go of the gas and repeat the process and it happens again.

My issue is that I cant figure it out since I Need to be driving to hear the hissing and the turbo cut off. I looked around the threads but nothing really seems to match my issue. No codes either. On top of that I've never owned a 1.8t and don't know much about its turbo.

Golf IV / Jetta IV :: 2000 - Hissing Sound Coming From Bottom?

Ever since I bought my 2000 mk4 golf I've had this super loud hissing noise coming from the bottom of the car. Almost like someone is spraying compressed air when your foot is on the throttle. Sound gets louder the more you depress the pedal. Had a catalytic converter code so after a few months I bought a new cat, welded it on, and the sound fairly went away. Still present, now months later the sound is now a bit louder but It's gotten on my last nerve, I want to fix it but I can't seem to figure out what that noise is.

Almost sounds like my car is a classic beetle by the way it accelerate at times. The car is sort of sluggish than normal at times, no codes, no lights, sometimes peeling out in 1st gear the car hesitates like I have regular power, then I have this sudden burst of 1 second power then back to normal until I shift then I never feel it again until I'm back in 1st and WOT it. Car does smell like gas a little sometimes, not too prevalent but nonetheless noticeable especially going in reverse. My gas meter seemed to fluctuate at times, I may have a bad pump maybe, not sure if that has anything to do with it.

Santa FE SM (2001-06) :: Hissing Sound When Go Above About 2000 Rpm While Accelerating

So my 2001 SF GLS (220,000 km) has developed a quiet hiss on the RHS that's only present when I go above above about 2000 rpm while accelerating. Starts and stops instantly with the gas pedal. Maybe some crap in the fuel line? It doesn't seem to affect performance, but it could be a sign of something developing.

Passat (B6) :: Hissing Sound When Accelerating - RPMs Not Rising

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.

Ford Super Duty (1999-2016) :: 2015 F250 - Whistling Or Hissing Sound While Accelerating?

Have a Whistling or hissing sound while accelerating? My 2015 6.2 seems to make this sound while under load. I took to dealer and they claim its the throttle plates not closing all the way. Claims this is normal, but to me it is annoying. Just would like to know what others think.

Golf IV / Jetta IV :: Front End Clunk Sound Occurs While Braking And Accelerating Over Bumps

A clunk sound coming from the front end. Drivers side and Passenger side. Not really a metal on metal sound. The problem started after coilover install. The sound occurs while braking and accelerating over bumps. So what I've replaced:

-Strut Mounts and Bearings
-Lower control arm bushings (R32 bushings)
-Drivers Side CV axle

What I've checked:

-Tie rod ends have no play
-Ball joints have no play.
-I have no sway bar, so not the sway bar bushings.
-Its not the axle hitting the frame.

Could possibly be the dog bone mount but when I installed the 1' motor mounts I saw no issue but could possibly be the bushing. feel the clunk in my foot as well.

Golf IV / Jetta IV :: Hissing / Buzzing Noise At Certain Speeds

2002 Jetta 2.0 4-speed auto - 151,xxx miles.

Symptom: when driving, occasionally there is what I can only describe as a fairly loud (but not overwhelming - radio easily drowns it out) hissing+buzzing noise. It's a bit like listening to a small plastic gear grind at a very high speed with a bit of a hissing as a backdrop. It only happens occasionally, and I haven't identified any glaring rhyme or reason to when it happens.

What I can say is I've observed it around shifts on fairly strong acceleration, I've observed it climbing long hills, and I've observed it when cruising ~60mph on the freeway. It SEEMS like it is sensitive to the gas pedal - when I hear it, if I depress the pedal more and accelerate I tend to move beyond it, but if I let the pedal off and decelerate (thinking of the 60 mph freeway case here) I can bring the sound back. And if I continue to decelerate we move past the noise.

So, I can't really tell if it is RPMs, or speed, or engine load, or...

A little about my history with the car: I bought it only 2,000 miles ago, so I can't say much about what is "normal" or has been going on for how long.

A little about the transmission - I know they have a very bad rep. I had the trans fluid changed with the correct type right after purchase. It generally shifts ok. There are occasional delays going from reverse into D, and sometimes shifts on acceleration are less elegant than you'd hope, but it seems to generally function as a 4-speed transmission ought to.

This noise is something failing, and given that seems to relate in some way to speeds/loads/possibly shifts I hope this isn't a sign the transmission is going to suddenly give out.

Golf IV R32 :: Hissing Sound From Rear Of Engine Bay

My car has been making a hissing sound when I turn it off for the past few weeks, I checked the hoses around the intake manifold and they all look to be attached fine.

I took a video and discovered a flex in the rear of my manifold..is this normal? What would be the common issue?

Look at the rear of the barcode label

Golf IV R32 :: Hissing And Ticking Sound That Loops At Idle

I'm hearing a weird mix of hissing and ticking sounds.

I captured ONE loop of the sound on video, the sound loops and loops and loops at idle.

My car has just under 40k miles on it. I was wondering if this sound is normal at idle? Or if I should get it checked out.

Golf IV / Jetta IV :: Buzzing / Hissing Noise At Certain Speeds / RPMs / Loads

I have a 2002 Jetta GLS 2.0 4-speed automatic, 151,xxx miles... I have only owned it a couple of thousand miles, so I can't offer much on what is "normal"...

The issue I am having is as follows: I sometimes get a strange buzzing/hissing noise that sounds like it is coming from the engine compartment ~45 degrees to my right while driving. It's very hard to describe - the best I can say is it sounds a bit like a little plastic gear is spinning/grinding at high rpms, yielding a buzzing noise, and there is a hissing-like sound as a backdrop.

The sound happens only occasionally (but seems to be happening much more frequently, which is worrisome). I have heard the sound in different driving scenarios, so I can't say "it only happens when...". However, it DOES seem to be sensitive to throttle and driving conditions in some way. I have heard it while a shift is taking place, I have heard it under load on a long incline, and I tend to hear it right around 60mph. Interestingly, in the 60mph example, can make the sound go away by accelerating past 65, or by decelerating down to ~50... it seems like there is some kind of transition taking place at 60 that fosters the sound?

The transmission is generally functional - I had the fluid changed right after buying it (with the correct fluid), and it generally shifts ok. It does have some of the quirky behavior the transmission is known for: occasionally hesitates to go from R to D, sometimes shifts while driving are less subtle than they should be. But I'd say as a whole it operates as a 4-speed transmission would be expected to.

However, since this strange noise is getting worse, and seems to be related to shifts/load/andor speed in some way... I am worried about trans health. What to check? Because it is intermittent, and doesn't exist at idle and rarely appears when going around the block good luck getting a mechanic to observe it...

Ford Excursion :: 2004 - Hissing Sound When Stepped On Gas?

My 2004 excursion left me stranded in Louisiana this weekend and I had to drive a rental back to Austin today. Was running fine and I got up to come home on sat and the turbo would not engage. When I would step on the gas I could hear a loud hissing sound, the more I stepped on the gas the more of that sound I could hear. Truck would not accelerate at all and almost felt like it was going to come apart at 50 mph. The error code I got from auto zone was turbo issue. and it gave me possible reasons. I checked hoses to and from turbo all hooked up and seemed to be in working condition. There seemed to be some black soot along the top and back of the engine. It would idle fine, but trying to drive it was impossible. I left it at a Ford dealership in Lafayette and await the news. I have a powertrain warranty up to 113,000 miles I hope it covers repair.

Honda - Accord :: 2004 - Hissing Sound Of Shooting Air And AC Went Warm

Honda Accord Ex 2004. My AC stopped working today. After sitting at a light in the FL heat I heard a hissing sound of shooting air and the ac went warm. I tried a can of freon but the gauge read in the red and it wouldn't take a charge. It doesn't sound like the compressor is clicking on.

GTI 337/20th Anniversary :: 2004.5 GLI - Constant Air Hissing Sound Coming Into The Cabin

I installed a Eurojet "Street" FMIC on my 2004.5 GLI a few weeks ago and ever since there has been a constant air hissing noise coming into the cabin. The noise has proven to be tricky to diagnose. It is loudest inside of the cabin and isn't audible under the hood. I boost leak tested the system and didn't find any obvious leaks. The sound doesn't appear to be boost related.

I don't seem to be loosing performance. (I've read a 2-3 psi drop is normal after FMIC install) The sound is constant and is faintly detectable even at idle inside the cabin. The sound's volume is dependent on the RPM's the engine is turning. The sound is constant whether the engine is on boost or vacuum. I can't explain this. My car isn't throwing any CEL's at all.

My mods are Revo Stage 2, 4 Bar FPR, 42dd TBE, Hyperboost DV, FMIC.

Ford F-150 (2004-2008) :: Slight Hissing Sound When Lightly Press The Accelerator And Then Stops

I have a 2004 F150 4.6L... There is a slight hissing sound under the dash on the drivers side when you lightly press the accelerator and then stops. No matter what speed you are going as soon as you apply the accelerator it hisses then stops. There is also the same hissing , only louder when the engine is cut off. It hisses for about 3 seconds. What could be causing this. It has been idling rough since the hissing started. The check engine light is on and showing P0420 and P0430 codes . The cats were replaced with resonators so I believe that is the reason for the codes.

Golf IV / Jetta IV :: 2004 - Tink Sound From The Turn Signals

'04 Jetta Wagon TDI I just bought for my brother and his family. The car is in unbelievable condition even with 206k on it. I have met my match in automotive anal-retentiveness as there's not even a door ding on it. The tech who did the pre-purchase inspection wanted to buy it from me before I'd even paid for it!

The Hubster drove the car home after paying up and found that the "tink-tink-tink" sound from the turn signals continues on after the signal has been turned off. It's much worse when using the right turn signal than the left. It often does it for no logical reason, like when driving on the highway.

I owned a '00 VR6 GTI for 12 1/2 years (bought new) and never had this problem so I'm at a loss. We want to give the family a trouble-free car and are hoping this is an easy and inexpensive fix, not one of those really expensive .

Tiguan :: Hissing Noise When Accelerating Hard

Noticed a brief hissing sound when accelerating firmly? Doesn't seem to be coming from the engine compartment, maybe from under the dash, it is very brief, a couple of seconds tops and sounds a bit like pressurizing a container just before the valve closes. Not an issue, not even a nuisance, but I am curious about it.
