Golf IV / Jetta IV :: Faint Squealing Noise
Jun 23, 2015
My wife and I have a 2002 Golf, Manual transmission, 2.0L, L4, 8V with 178xxx ODO.
About a year ago I started hearing a very faint squeal that would always squeal, regardless of A/C use, no power loss is felt, in fact, the A/C works great and the car runs perfectly. But after a year of driving and 1 big road trip, the sound is now unbearable.
I recently replaced the alternator, belt tensioner, and threw on a new belt, but still, the squeal persists. After holding a rubber hose to my ear and moving through each accessory pulley with the other end of the hose, like a ghetto stethoscope, I know that it is definitely coming from the A/C compressor pulley.
I found a video on the Youtube that perfectly catches the same squeal (not my car, not my video) [URL]....
Since the A/C compressor has a clutch, and the outer pulley is constantly spinning with the serpentine and there is no noticeable difference in the noise whether I am using the A/C or not, I think that the outer bearings on that clutch need to be replaced.
Should I just replace the whole clutch and any good DIY threads on this? I've looked but all I can find is a DIY for a TDI, which I don't know if it's the same compressor or not.

Ok so I have a 09 tiguan S that stalled yesterday while driving only a few short min. My wife had been driving home about 4 miles when she got home I could hear a faint squealing noise as she pulled up. I left right after and assumed it was the the ac belts it that exist, so to verify that I turned off the ac and the sound did fade. I drove with it off for a few min then turned it on again the car acted normal and cooled just fine then about 5 min later I pulled into a lot and while waiting for others to move the engine stalled and I had the engine light, epc and battery lights showing. Now it was something like 110 outside and I thought overheated but the temp gauge showed normal and I received no warnings. I smelled a burned rubber smell and I recall seeing a small puff of smoke. I could not locate anything that could have burned out. The only thing I could see that was unusual was what looked like buildup on the air intake tubes.

My 2003 Jetta GLS 1.8T just started doing this... I am not hearing the normal Turbo whistling noise when I give it a lot of gas, however I now hear a squealing noise. Sounds similar to a loose belt kinda whining/squealing. I do not hear this at any other time, only when accelerating quickly.

So I drove my car (2000 vw golf tdi auto) to work fine. When I started it to drive home, it squealed and then all of a sudden stopped squealing so I popped my hood and looked and the belt can fit 2 fingers under it. Is there anything I can check diagnose this? I hear it could b a tensioner pulley.

Belt squeal but when I have clutch pushed in no noticeable noise.Abs kicks in at low speed stops. I sprayed the belts with dressing noise went away momentarily actually sounded like it could have killed it almost. Right now I have the and fuse pulled to just get me by.

So I recently swapped my 2.8l 12v vr6 for the same engine because mine blew up, everything went good and the car runs great but there is a faint kind of rattling sound coming from the top of my motor, when its idling it will be a constant faint rattle. It gets worse as i accelerate between 3 to 4.5 rpms but then stops making the noise when i really start cooking so Idk if I just can't hear it or what. I've tried looking it up but i can't seem to find a video that has the same problems as my car. My father told me it could be my rockers or valves and others have told me it could be my timing chain or guides. I would love to just take it to vw to get it diagnosed but I don't have the money. I will try and upload a video of the sound ....

I have a mkiv and before I got to work in the morning, I warm up my car for about 10 min. When I start it up the belt squeals. I do believe that it only does it in the morning. Should I have it checked out? i put belt dressing on it last night but it squealed when i started it up this morning so I don't think that worked......

2 days ago I changed my driver side wheel bearing and put in a new cv shaft
The axle nut may have been somewhat over torqued but nothing crazy over the spec.
Everything else is as per spec.
My problem is that every time I turn left slow fast sharp not sharp it's making this good awful noise.
It is not a constant squealing. It's every rotation. On off on off on off. No bearing humming or anything when driving straight or turning right. Just left. I'm pretty good at solving pretty well anything with my gti but this one has me stumped

I've had my car for less than a week and have noticed something, I want to check with you all here to see if it is common or not.
When in 2nd gear with my foot off the gas between 1-2K RPM, I hear a faint whining sound that gets lower in pitch as the RPMs drop. An example of when this would happen is if I were coming up to a stop sign in a residential area in 2nd gear, coasting to the stop sign. The sound starts a little under 2K RPM.
I don't remember hearing this in 3rd gear and I haven't tried in 1st.

So I have an odd whistle noise, when I give it a little gas it makes a faint whistle noise. Only happens on acceleration with a little gas, I don't think it's the turbo.

I have an 05 Jetta Wagon GLS 2.0 which has been amazingly resilient. I had the 100k check up done recently and everything still came up positive; the battery conked out at 120k; and I just recently replaced the stock head and tail lights out of proactiveness rather than them going out. But, I think I've run into an issue now. When I drive through a puddle (or otherwise get water significantly on the underside of the car) if I am running the AC at the same time the engine makes a squealing noise as though a belt is slipping due to the water. I presume is the case that a belt is slipping--and I imagine that is part of the reason it idles noisier than when it was new, but before my wife and I make a budget I'd see whether there are other options. As it is there are 130k miles on the car, it's a 5spd standard, and other than oil changes and the checks at 30, 60, and then 100k no real service has been done.

What happened to my 02 mk4 Jetta after start up and engine failure.
I started the engine, and noticed a high squealing sound just like a loose fan belt, as I backed out my driveway the Battery light came on and engine died, when I tried to re-start the engine it doesn't make any cranking sound just a whirring sound.

2015 GTI, 6sp, Coupe, 3000km.
When changing gears from 1st to 2nd and 2nd to 3rd, I get this faint THUMP thump noise coming from what seems to be the driver side foot well area, on the other side of the firewall.
Other ways to replicate is by simply clutching in as if changing gears, but not actually shifting. It can be prevented by shifting/accelerating very slowly (not practical).
Nothing can be felt in the clutch pedal OR the shifter. Can't be replicated in neutral, or by simply letting off the gas under boost. ONLY when the clutch is engaged about 2.5k RPM in 1st, and 2nd.
What it could be. Dogbone bushings? Engine mount? Gerbils? Also, went to dealer and they said it wasn't "enough" for them to start pulling stuff apart. Was told to wait until it gets worse.

Started a few days ago, There is a faint whistle noise when I am open throttle around 2500rpms. It lasts for about a second and does not occur at any other time. It does not occur under gradual acceleration, or when the car is parked/in neutral and just revving. I tried searching the forums *a little* bit, but my keywords just may have not been right.
My first inkling is that it may be related to flapper, since the rpms seem right and sounds vacuum related to me. But, the unit is completely disconnected (have borla cat-back) and the hose is ziptied, so is this possible? I will try to get a video of the noise later today.

So I have a 2002 GTI VR6 with the 24v BDF Engine. I have been having a problem with my belt squealing. It started after I replaced my water pump and crack pipe. While I was at it I replaced the belt tensioner and belt with a kit from ECS than had an aftermarket tensioner and a Conti drive belt(has 6 ribs). When starting the car up for the first time after doing the water pump I noticed the belt was squealing. It would only squeal when I gave it some good throttle.
After a few minutes it stopped squealing so I figured it was some coolant or something on the belt. Well its been a few weeks and it continues to squeal when I give it throttle, but only if the ac is on and it will only do it for a few minutes. After a few minutes of the car running or driving down the road it doesn't squeal anymore. I did make a long drive in the rain very shortly after replacing the belt and it was a really heavy rain storm. There was a lot of water on the road and my belt was squealing pretty much the whole drive if I had the ac on. I had to alternate ac on and off so I could keep the windows defogged.
After that experience I put on a set of engine splash guards from ECS. (note these guards were the ECS branded ones and were a terrible fit. Holes didn't line up with studs on bottom of frame and ended up taking the middle belly pan section out as it would hang down way too low even with the side covers connected to it.) That seemed to keep it from squealing while driving in the rain but it still squeals after first starting the cold engine with ac on.

I drive a 2010 Golf Wagon/JSW, and when I'm going at speeds around +60 mph/90 kmph and lift off the accelerator a faint high pitched whirling noise comes on. As soon as I tap the gas pedal it goes away. What this could be?
It's been a week now since I've noticed this, I guess I've never noticed it before or it's getting louder..i don't know?

How to identify this noise? I'm guessing water pump or timing chain tensioner but not sure.

I had the car checked for an odd noise that I've been noticing once the engine is warm. Almost like a humming or low pitch squealing. It's noticeable at idle and low speed from inside and outside the car. Very annoying considering the thing is a month old. Any way, I spent nearly 4 hours waiting and they came up with no solutions. Not a clue, a guess, nothing. The car is still driving normally and i needed it for tomorrow so I didn't keep it over as they suggested. The service manager said he hasn't seen anything like it, but also admitted he knew very little about the '10s. great.

So over the past view days I have been hearing some sort of light squealing noise coming from my car during my daily commute. At first I though it was wind noise or something stuck in the grill of the bumper. When I looked the car over this morning, I didn't see any plastic or something caught in the grill to be causing the noise. Then I thought maybe its my wheels, brakes, or rotors but found out it wasn't that after hearing the noise stopped at a stop light. I did a few revs and heard slight squeal coming from the engine bay.
So I don't really know what to look for now. The sound is fairly faint, but a high pitch squeal.

Ive got 20K miles on my car now and I noticed a weird noise in the engine bay at certain rpm's. Between 1800 to 2300, parked or driving. It sounds like a bad bearing, like when you spin a bearing with compressed air it squeals. So i decided to investigate this further.
What Ive found is that the top timing belt small roller bearing is the culprit.
My friend with the same car has the same noise with the same mileage!
My cars engine is all stock except for the VWR air filter and Forge DV.
