GTI 337/20th Anniversary :: 2004.5 GLI - Constant Air Hissing Sound Coming Into The Cabin
Oct 30, 2015
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.

My 04 hyundai accent about 2-3 months ago acquired a hissing noise which seems to be coming from the middle of the engine compartment. The car only has 100,000 miles on it.
It is a constant hiss that only stops when the gas pedal is pushed initially. I have looked all over the car and can not see any fluids leaking at all. It is pretty loud and can be heard easily outside the car when the car is on.
I hooked up my obd2 reader and found these codes:
P0304-Cylinder 4 misfire (I notice it when the car sits at idle for about a minute)
2x P0121- Throttle Position circuit range/performance problem
2x- Evaporative emission incorrect purge flow.

So your clutch pedal operates properly, the clutch engages with no issues, but this annoying squeak, snap, crackle, and pop noise keeps coming from the clutch pedal within the cabin.
Could it be your clutch master cylinder? CMC is not leaking in the engine bay and the driver footwell. Not the CMC.
Could it be your clutch switch that's used to control revs and cruise control? Removed it and clutch pedal still made noises when pressing and releasing the pedal. Not the CS.
Could it be the over-center spring that sits behind the clutch pedal assembly? How could it be? It's just a spring. Springs that compress in that orientation don't make snap, crackle, and pop noises.
What most people fail to realize is the noise is coming from the pedal assembly, but it's not the pedal structure or the pedal. It's the pivot point where it mates with the clutch pedal mounting bracket. At the pivot point are two bushings (one on each side of the pedal structure) that wears out over time creating these noises.
Please look up the part number for these bushings. They look like the following at this link but these are aftermarket upgrades for BMW's.[URL] ....

So, when i throttle down i get a hissing noise, almost like a very small jet engine. then when i let off the throttle I get the psh psh psh psh noise and not the solid pssshhh noise.

I've been trying to locate the source of the noise that is coming under the car. Specifically below the handbrake. Like something is lose, took the car to a shop to have it inspected, checked the exhaust, and there was nothing there, all clamps there and screws.
It only happens most of the time when the car is cold and it feels all the way from the hand brake to the stick shift. Sounds like a rattle like something is about to go off from the car but I cant imagine what could be. Couldn't replicate the noise at the shop, only when you are driving and the car is in inclined it rattles really bad until the car gets back to the normal position. Specifically in 1st gear .

So my 1.8T GLI is making an odd sound that sounds like it's coming from the right side of the engine. Sounds like a busted bearing of some sort. Not too keen on this engine yet...

A 2003 20th GTI (1104). It has the 1.8T engine. Car has appx 75k miles on it, timing belt has not been done yet.
My concern is here: I checked it out the other day, and while it was running I heard a soft whirring sound coming from the engine. So I popped the hood and I couldn't really put my finger on what it could've been. I liked the car aside from that, and would like to get it, but I don't want a car with problems.

02 GTI 1.8T ... Stage 2
Was running the car at about 4500 rpms in 5th gear. All of a sudden lost power and heard a loud whooshing/ hissing of air which sounded like it was coming from under the front passenger side of the car. Lost about 50% of power in all gears. What I screwed up and broke?

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.

We purchased her GLI a couple of months ago, as is, knowing the issues it had and whatnot. We talked the dealer down so much that he refused a warranty.
This pesky *clunk* sound coming from the driver side front-end. Usually on bumps, it sounds like a suspension deal... We took it into a shop, they "re-torqued" the suspension, and did the alignment. It was good for about a week, then it came back. Also, there's a creaking sound when turning, my guess is CV boots? Axles?

so I bought my gli about a month ago assuming it needed a clutch (got it for a steal so wasn't worried about it) the kid I bought it from didn't really know much about the issue but it was a constant grinding when in gear and moving but the second you engage the clutch it would stop, and quiet down completely, so I dropped the trans and inspected clutch, throw out bearing, & fly wheel it all looked new.
So than my second guess was it was something internally in the transmission so I sent it out to be inspected and repaired as needed. I got a call from the shop today that said everything was perfect so I am completely stumped as to what my problem is. I have a new clutch, flywheel, throwout bearing, all new linkage, & am changing fluid. I don't know what else it could be and really don't wanna have to drop the trans again once its back together.

My 337 didn't pass inspection (control arms, inner tie rod, no cat because the guy I bought it from sucked etc) but it sat for probably 3 weeks and I just sold my other car (I was planning on using that $2000 to get the 337 to pass inspection) but I just drove the VW down the street for the first time and it's making some scary sounds.
Basically when I give it throttle there's a high pitched whirring sound and something keeps rattling that sounds like its coming from the engine bay. I'm really freaked out, I'm leaving in two months because I'm transferring to a new college and I need this thing to run perfectly.
It's also shifting a little strangely and if you don't shift absolutely perfectly then it starts to rattle (not like you're about to stall but something completely different) I can't take it to a VW dealer or anything because I'm way over the 15 days past a failed inspection and I can't afford a tow.

I originally own an mk4 r32 but my friend owns a 20th.. He recently lowered his car about an inch or 1.5 of an inch he might have a finger gap.. He is on jam coilovers all the way down in the rear and about 20 threads left up front.. There is a nasty sound coming from the front driver side when he is turning or going straight.. he still didn't do an alignment idk if that matters.. and he also miscounted the threads so his driver side is about two threads higher but he fixed that now.. he also doesn't have camber plates up front does this matter?

I was sitting at the stoplight in neutral when the light turned green. I pushed in the clutch and put the car in first then all of a sudden a huge CLUNK like when you take out the starter bolt without supporting the trans or motor. Then while letting out the clutch about halfway all hell broke loose. It sounded like a bunch of marbles rattling like crazy in the trans. I pushed the clutch back in then it stops until you let it back out again. The car still moves forward and reverse but with all that noise. The sound seems like it's coming from under the driver side motor mount. When I put my hand on the tranny I can feel the vibrations very well. Does this sound like the throw out bearing?

Well I parked my car yesterday evening and its fine. Well this morning I go out and try to go to work and my keyless entry doesn't work. So I unlock the door manually and as soon as I open the door I hear this clicking soon almost sounds like the blinker but faster and more erratically. All cabin lights are flickering and the car has no power the battery is dead. What could cause this? Is something shorting out, Could my aftermarket radio stayed on and drained the battery? Maybe it was clicking because the cabin lights were trying to come on but didn't have enough juice. Well I am charging it now and I am gonna see what happens.

So there's been a noise coming from what seems like the transmission for some time now.Here is how it began...One day I was reversing and noticed this clatter/grinding/vibrating noise coming from underneath my car. It only happened in reverse.However, now it's happening in all gears but not when accelerating, ONLY on deceleration in gear.
There's no clutch slipping, no noticeable loss in power, etc. Just the noise.I don't want to start replacing things left and right hoping it will fix it so throw-out bearing, trans mount, flywheel, etc?
2004.5 GLI 1.8T O2M. Transmission hasn't been touched from what I know of (bought the car w/ 37k, now has 77K),

Got an 04 GLI and I have the infamous hazard clicking sound. I replaced the hazard and it's still clicking, even worse than before. I'm going to spray some contact cleaner on the plug to see if that might fix 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?

Noticed 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.....

I have a 2016 SFS 2.0T.
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.
