Golf IV / Jetta IV :: 2002 GTI - Loud Whistling Sound On Cold Start
Mar 3, 2016
I am having an issue with my 2002 GTI 1.8T. I have tried searching for an answer to this, and found a couple things saying maybe it could be the secondary air pump but wanted to get more opinions before I go shell out money to chase this problem.
When I start up the car in the morning after having it sit overnight, the car does the normal thing where it increases rpm's to about 1100 to warm it up. During this a loud "whistling" noise can be heard. Once the car is warmed up a little bit, the rpm's decline to about 900, and the whistling sound goes away. When this happens though it almost sounds as if a valve or something is closing causing the noise to go away.
Also, I am unsure if this is related to this, sometimes when I am driving, I will be accelerating and the car seems to stop accelerating as strong as it was, boost goes down from around 8 or 9 psi to about 4 and I seem to lose power as if I had let off the gas some. When I put my foot further down the car accelerates harder again and boost goes back up.
I have already changed spark plugs, cleaned MAF sensor, and run the 3m 3 part engine cleaning kit through it.

My car has started making this loud whistling noise. It only happens when right after starting it when it's sat for a few hours and fades out within 30 seconds but has lasted for a couple minutes before. It drives fine but I know the sound isn't normal. Here's a video of the noise: [URL] ....

Today in the morning it was slightly cold so I turned on the heat in my car. The fan started making a loud whistling sound and in about 2 minutes it stopped. Is this a sign of a bad fan?

I have a 2003 VW Jetta GLS 5 sp. Manual with the 2.0 Naturally aspirated 4 cyl engine. The car has approximately 147,000 miles. My MIL light has been on for some time now. I recently got my local mechanic to run diagnostics on it and he reported two error codes (411 and 420). To my understanding, 420 is due to the imminent failure of a catalytic converter, an issue which I have addressed by replacing Plugs, wires, distributor, and cat.
My real question is, I would like to know if a mysterious Vacuuming sound that comes from my car whenever I start it cold in the morning and persists for about 25 seconds, and then comes on and off intermittently, is related to the 411 code. My local mechanic told me that there is some kind of exhaust recirculation motor that may be going bad.
I love my VW and want to keep it running properly rather than give it up, so long as there is no serious problem that is impractical to fix.

My car is making almost like a clunking sound when starting. It doesn't do it all the time, mostly it is when its a cold start but its happening more frequent. I have the push button start, would warranty cover this?

I've a loud squeaking sound coming from the front of the engine on cold start. This only happens when I start the engine after overnight parking . There are no squeaks when the engine is warmed up or when I start up with a warm engine.
I'm driving an 07 Camry and live in a region with hot tropical weather.

What could be the probable cause of the this and how do I rectify it?

I've had my 2002 Golf GLS for about a year now. It has 127k on it and I absolutely love it! Saves a lot on fuel driving 100 miles a day for work compared to my Ram 2500 diesel!
Anyway, lately ive been hearing what I can best describe as a "clunk" or maybe the sound of metal hitting metal when I go over a bump. From what I can tell it sounds like its coming from the front passenger side. Maybe the rubber grommit on the strut tower is gone? I havent really checked it out becasue I havent had much time on my hands lately.
Also, ever since I have had the car the engine seems to run louder than what I expected for a VW. It has the 2.0 engine in it. Is this normal? It kinda hard to explain how its running loud but when its at idle and I have the hood up it just doesnt seem as quiet as I thought a VW motor would sound.

So I replaced my rear coilovers on my gli assuming the driver side was broken because when over bumps it would make a loud banging sound as if it was bottoming out but after replacing them i have the same problem.

I have a 1990 F250 4x4. Whenever its below freezing outside, I get this whistling sound coming from the rear of the truck at very low speeds, like when I'm slowing down to stop at a light, or when I'm turning a corner. Pressing either the break or gas pedal seems to make no immediate difference in the sound. I took it to my mechanic, but it wasn't cold enough that day for him to hear it. But he did say that it is probably just that the rear differential needs servicing. Okay, so I drained and replaced the differential oil and gasket myself the next weekend. Next cold day came around and the whistling is still there.

So here is my situation, back in September I had to replace my passenger side cv axle on my 99' Mk IV Jetta and ever since then I have had a vibration whenever I exceed speeds over 70. This vibration is accompanied with a droning sound that gets louder the faster I go. But the weird part is all of this only happens when I am accelerating. If I push in the clutch or take my foot off of the accelerator it goes away immediately. Since all that started (for other reasons I might add) I have replaced the tires, both front ball joints, the driver side steering knuckle and both front struts.
Additionally and I'm not sure if this is related but it does seem coincidental. The muffler bumps on the body when I'm accelerating as well, but only after the exhaust has warmed up. I am at a loss. When the tires were installed they did a balance on the wheels and they didn't say anything about the wheels being bent or "out of round".

Driving my golf to take daughter to airport, all or a sudden there is this very loud metal scrapping sound. So I pull over and see this metal bat hanging from under the car and rubbing on the ground. At this point I'm not sure what it is and cant really budge it or dislodge it.
Anyway called for roadside assistance and a towtruck comes. The guy lifts the car a bit and is able to free this metal rod. Its about 1.8m (6ft) long and about 5mm thick (approx). Couple of photos below. Not sure if its part of suspension, steering or something else. Did have a mobile mechanic today doing some work on the cooling system (flange) he had to jack up the car.

I have a 2002 Passat GLS and when I tried to start my car this morning, it would not start. When I turn on the ignition, the car gives off a loud clicking sound. The interior and exterior light works, the panel light works, and the radio works as well. What might be the problem?

I am a newbie of the Golf R32. There is something curious when the operation speed of more than 120km On the right side of the engine compartment are as mad as a strange noise.
Quite a loud noise like whistling, as a rapidly rotating. Is this the original R32-sounding? I heard this noise because the sound generator is this true?

I am trying to narrow down what could be the issue to my 2002 vw Jetta VR6 air conditioning. It is blowing air but the air is not cold. If I need to add refrigerant, where I can find the low pressure valve so I can do this on my own with one of those store bought cans.

So im trying to diagnose my girlfriends issue with her car. When she starts it, the car will make a very loud rattling sound, not really grinding, but like metal on metal contact. Sometimes the sound goes away, but when the car is cold it is a guarantee. The battery light is also on, which was not the case when the rattle first started. I first thought (and hoped) it was perhaps the serpentine belt tensioner as I researched that when it fails it can make a loud rattle sound.
Once replaced, the same issues occurred. So I went ahead and put the old one back on since it was not the issue. Note that the old one and new one both shared the same tension applied to the belt and the pulley was still smooth without issues.
Using a stethoscope to try to determine the location of the rattle a bit more precisely I found the noise to be coming more from the alternator. Weird because I recently replaced it within the last year. I went ahead and removed the tension from the belt and played with the alternator for a bit. The clutch felt good when i used a screw driver to hold the fan and tried to move the pulley. One direction moved with ease while the other direction refused to budge, perfectly normal as I researched. The thing that I noticed that I thought was unusual was the fact that the shaft of the alternator had some play (Video below).
The belt has plenty of tension on it so i do not believe that it is slipping on the alternator. I push the belt with the tensioner engaged and the tensioner does not budge.
I decided to measure the voltage coming off the alternator with the car running and it was at 10.95 which im pretty sure is very low for these cars.

I've noticed during the winter my 2012 6.2L engine seems to 'whistle' when it is cold. It also seems to do it intermittently...that is, it always whistles when cold, but it might stop for 30 seconds and then do it again. It does it at idle, and also when driving, just until it warms up.
What is it, and do other people's trucks here do that? I was thinking maybe the engine fan, but why would it cycle on and off for maybe 30 seconds. My other thought was A/C pump.

So out of nowhere my car made a loud whistling/wining noise when i started it up in the morning last saturday. i applied some pressure to the clutch and it went away. talked with a vw master-tech buddy of mine and he said it possibly might be the slave/throwout bearing, but couldn't tell me until the car is opened up for inspection.
Fast forward to this morning, car ran fine and the noise was intermittent. get to a stoplight and the clutch pedal travel was 1/2 what it usually is. made another shift and the pedal fell to the floor. i was able to limp it to my jobs parking lot.
Now as we all know, this isn't an inexpensive repair and while the trans is open would be the optimal time for a clutch replacement. However, the clutch felt fine with no slippage prior to this hiccup. I am opting to just replace parts that are no longer functioning, but if i need to replace the clutch. which kit(s) should i consider? my car is a daily driven with occasional runs thru the mountains and canyons.
My mods: blue haldex controller/miltek catback/neuspeed pulleys/neuspeed chip/vf mounts/among other suspension upgrades.

2004 Jetta 1.8t manual, sport package with about 85,000 miles on it and I've owned it since new.
About a year ago I had a shop replace the strut bearings while it was in for some other things. After I picked it up my alignment was jacked and there was a binding sound coming from the front end. The shop said the sound was just the springs settling in. It did go away after a while. Still don't understand why the alignment was off but I aligned it myself and all was good for a while.
About two weeks ago I myself replaced:
Lower control arms (stock VW) and ball joints (FEQ or Lemforder, not sure which) with R32 rear bushings and poly front (I HATE poly bushings but that's for another time)
Tie rod ends (FEQ)
Front brakes & rotors (stock VW)
I also threw in a oem Audi lower stress brace while I was under there but I don't think that has anything to do with my problem. Then I took it to a shop to have an alignment done on it. Everything is now within spec except that the caster is 6.6 degrees on the left front and 6.2 degrees on the right front. How does this happen?
So now my problem: There is a fairly loud binding sound coming from the front of the car randomly. It sounds like the coil spring is binding but maybe it is something else? it mostly does it when I reverse for a bit and then put it in first and drive forward or forward then reverse so something is shifting front to back. Steering doesn't really seem to have any noticeable effect.

I own a 2001 Jetta 1.8t with Gti front end. So I was driving downtown the other day and I bottomed out really hard and cracked my oil pan. I didn't realize it was cracked and leaking so I drove it home, drove fine with no issues at all. When I got home I parked it and went inside and in the morning I came out and tuned it on for maybe ten seconds. It made a really loud ticking sound that was constant and oil pressure was almost all the way down. So I shut it off and looked and saw the oil pan. I fixed the oil pan yesterday and started it up and it sounded really good and drives fine. But I've been hearing a pretty decently loud ticking sound when everything's up to temp and warmed up. The ticking is only at an idle and it drives like it use to just sounds bad at an idle. Some people think it's my oil pump and tensioner, some people thing I ruined the turbo and possibly internals.
