I installed a usp test pipe a while back and I noticed a hissing sound coming out from my cluster right after the install. I have seemed to ignore the sound but now its getting to me.
View 10 RepliesEver 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.
I noticed a hissing sound coming out from under the car. It's more audible closer to the rear of the car as if air is escaping through a hole. Tires are good and not loosing air. When the fans turn on the hissing sound goes away momentarily and comes back. What could this be?
View 13 RepliesNoticed hissing sound coming from the rear windows when the AC is on... It's very annoying so I always crank up the volume of the music. Funny thing is when you open one of the rear windows slightly and the sound is gone. I thought it was from the roof rack but it's not.......coz the sound is there when the car isn't moving too.....as long as the AC is on.....and the rear windows are closed tight.....

For the past week or so, I've been noticing a hissing sound coming from underneath the car near the front driver side area.
It almost sounds like air being let out of a tire. It only happens when the car is turned on, and the sound is there when the car is in park or in gear.
Not noticing any change when driving the car.
So I ended up removing my rear seats of my 2010 hatchback gs, but there is now a hissing sound coming from the rear where the seats were. The sound starts as soon as I start the car up until I shut the car off. I'm assuming that this noise has always been there just noticeable because of the seat removal. Is this just the fuel pump?
View 8 RepliesOk just so I know what the dealer may do to fix it....I have a weird hissing sound coming from the driver side like a vacuum hose is off or something...but when I apply the brakes it goes away...I let go and it comes back...when I shut the car off as well it stays hissing until I hit the brakes again or it just quiets down... What this may be?
View 1 RepliesI 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.
Well I've just noticed something quite annoying today... a very slight hissing sound coming from under the rear end of the car. A friend I drove to work this morning even said "what's that noise?".... It reminds me of the sound you'll hear when there is a pinhole in a joint weld, or a clamp is loose? My car only has 2800km on it!
View 8 RepliesMy Explorer overheated yesterday. Found a very loud hissing sound coming out from under the hood. Let it cool off filled it with antifreeze, started it up, started hissing again. Found the thermostat had broken. Replaced the thermostat. Filled it up again. After replacing the thermostat I found out the hissing sound was coming from the plastic thermostat housing. Replaced the housing. Again I refilled it with antifreeze.
Started to let it warm up and noticed liquid dripping out of the exhaust pipe. Checked it out. Had a green color to it. Then I noticed the coolant resivor was full up to the cap. I did not fill it up past the full line on the side of the resistor. Tried removing the cap.
Found out it had a ton of pressure under it. Bled off the pressure. Refilled it again. Did not put the cap back on. Tried starting it. Instantaneous geyser. Runs like it is missing on 1cylinder. No oil in the coolant that I can see. No coolant in the oil. Could this problem be caused by a blown head gasket of a crack in 1 of the heads or in the block?
So I have a hissing sound (kind of what the vacuum cleaner makes when air path is obstructed with debris) coming from passenger side foot area. The easiest way to hear it is to turn on HVAC and put the fan on the lowest setting so the sound of the fan does not interfere with the noise.
View 1 RepliesThe tweeter and the speaker in my passenger side front door have this awful hissing sound coming from them. The sound gets louder and quieter with driving. Could it be a lose connection at the headunit or would it be to each speaker? The speakers are stock by the way.
View 3 RepliesI changed my fuel filters a couple weeks ago. When I opened the hood the other day i noticed a kinda hissing or sucking sound coming from the engine mounted fuel filter. I've watched epics video a couple time and think his made the same sound but not sure. I am just paranoid with all the hpfp problems. It runs fine and had no long starts or hesitation at all. Lemme know if you all have the same thing. I just can't remember if it sounded like that before. I have done the air purge properly and several times since changing the filters. I notice the sound while doing the air purge procedure with engine off and key on.
View 3 RepliesMy 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

What it could be ??
View 5 RepliesI'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.
2004 Jetta GLI - I am getting a hissing sound when accelerating. Could it be the Turbo?
View 2 RepliesThere'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.
My car is Stage 2+ (mods are in signature). I noticed today a hissing noise coming from the rear of the car when my music was turned off. The sound is very similar to turbo spool but I'm 100% positive it is coming from the rear of the car not the bay. The noise does not show up until I hit 3rd gear and from then up it only makes noise when I'm accelerating. Under any load the noise stays the same. I can accelerate slow or accelerate a little harder and the hissing noise remains constant. The only two things that I can think of are the flapper valve on the SPM exhaust and the rear diff. However, I don't see why the flapper valve on SPM's exhaust would be affected by a certain gear.
View 4 RepliesI installed the non-resonated exhaust, but I noticed that some air/water condensation is coming out of the small pipe that join the cat and non resonated part of the exhaust.
I double checked the position of the small part and is very deep inside the other tubes, plus I checked the clamps too.
So I did the seafoam trick and I came to the conculsion that my exhaust leak is coming from either the manifold or the flex pipe. There was no smoke coming from under the car only a mist of smoking coming up from the back of the engine, probably by the manifold or the flex pipe. I do not see any visible cracking per say. I have attached a picture of the end of the flex pipe and it almost looks like someone may have tried to seal it before? I don't know if that is normal or not as seen in the picture.
