Golf IV / Jetta IV :: 2008 - Makes Annoying Noise When Engine Is Warm And A/C Is Turned On
Sep 8, 2014
Mk4 Golf City*, 2008, gas, manual, sunroof. Canadian budget-model.
Mysterious noise like WOMMMMM, WOMMMM itinerantly: Noise is only when air conditioning is on and the engine is warm. I can feel vibrations in the brake pedal. *You can't hear the noise under the hood*. It is quite loud in the cab, though, definitely coming from under the dashboard.
I have stuck my nose in. I removed the glove box and listened to the blower motor, it seemed to be coming from further toward the driver's side. It will be like wmmmmOMMMMM WOMMMMM pause WOMMMM like something is vibrating too close to something else and the friction causes it to go back to where it was.
I hit a speed bump going a bit fast. I broke the small cooling fan somehow so it was just loose hanging on its hub. I had that repaired but the noise hasn't gone away. It seems to be getting more frequent but so far there isn't any indication of the car suffering. This is the second summer it has made the noise.It haunts my sleep.

2005 jetta. On the highway when I hit about 75mph I hear this loud humming coming from either the engine or the exhaust, I'm not sure. It disappears immediately once I cross about 82mph. What could this be? Why such a specific range?

I have an 03 2.0 jetta manual shifter. Never had issues before this morning. Got in car and sounded like it wanted to turn but wouldnt turn over. After a few attempts the turning sound stopped and I heard an electric pop. Now engine won't even try turning when I turn key it just clicks and engine makes a high pitch noise. Took starter and battery out got both tested and they are fine...

I have an 1990 Toyota 4Runner. V6 engine. Automatic. 4wd. Today it blew an upper radiator hose. A few seconds after the initial pop of the hose and the spew of fluids the vehicle died. I replaced the upper radiator hose and the lower hose- and refilled the antifreeze. There are no leaks as of right now.
The engine will not start. The belts spin whenever the key is turned on. But the engine will not crank. You can hear the starter trying to start it up. Jumping the vehicle was of no luck. Charging the battery was of no dice.
The vehicle makes a whirring noise (belts spinning) when key is turned, but the engine does not crank at all. The noise stops as soon as you shut the key off. The oil is clean and full still.

So I just but my golf about a month ago and have hit many problems but the most annoying is the hum I get at 3500 rpms. In my searching I feel somewhat confident this is caused by a cheap right axle replacement. I also went under and found on the left axle markings that indicate its is oem VW and I was unable to find these on the right side. anyway I have found this: [URL]....
It says it is a hollow axle right there and it is 170 less than the cheapest oem one I have found. would this workout?

My 2004 Golf GTI VR6 6-speed manual makes a louder than usual decelerating noise while in 2nd, 3rd, and 4th gears. If I give it gas it doesn't make any noise but once I take my foot off the pedal it makes a louder than usual decelerating noise. It sounds almost as if something is maybe grinding but I'm not sure what it is. One mechanic said it may just need to be serviced (new transmission fluid). I've read some forums saying it may be the bearings or maybe need a new transmission. The car runs fine otherwise and there aren't any problems shifting up, it shifts really smooth. '
Its only when I downshift that I hear the noise. The noise is the same no matter if I'm turning or going straight and and it's in neutral, there ISN'T noise. It's only while in 4th, 3rd, or 2nd while decelerating. Even if this is a common problem with VW's how do I fix it?! The previous owner said it's been the same way since he's had it and it has NOT gotten worse and his mechanic said it was nothing detrimental to the car so he left it that way. The GTI has 130K miles on it and runs strong, that's the only problem it really has. I'm not sure when the transmission fluid was last changed so that could be a possibility. Going to possibly try that in a few days and see what happens.

Recently had this problem which started up about a week ago where my car would make this clicking noise whenever I turn left while driving. When I turn to the right there is no noise. Some said that it could be that CV joints need to be replaced. I have a video showing the side that is making the sound, maybe there is something abnormal that I don't see.

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.

i recently bought a 2008 vw passat vr6 4motion and i dont know if its just with me but the engine makes a annoying wining noise when i start moving(hitting the gas) no more than 2000 rpm. and i have got some bad mileage. i drove only 31 miles with a quarter of a tank. and that was grandma driving. i do not step on the gas more than 2000-2200 rpm.

Mmkay.. 2000 GTI VR6.. Will start initially, when engine is cold (sat overnight, or through the work day) but once the engine is at normal running temp, if you shut it off, it wont start. Acts like its out of gas.. have to "prime" and keep hitting the gas pedal while cranking, to (sometimes) get it to start when warm, and then it runs like crap until I get a few miles down the road.
Brand new plugs and wires, and just this evening, pulled a plug, and its obviously fouled, and covered with unburnt gas. Coil Pack maybe?

Car doesn't seem to want to start when warm.
1.8T AWD, 02J swap, no clutch switch (I can start without pressing the clutch).
Cold start, cranks and starts on a dime, after the car warms up and I've turned off the car, say went for a quick grocery run, the car won't start afterwards.
No cranking, nothing. Fuel pump primes, then not a sound. Everything on the dash lights up just fine. No starter motor noise, no clicking.... nada...
Fairly new starter motor pulled from a junkyard donor. Can't think of anything else.
Last time I got stranded in a parking lot, I gave it a few whacks with a tire iron and the car started just fine. Could it be a bad solenoid?

So, I have a 2007 Suzuki SX4, about 172,000 miles on it. Great little car. Love it. It's the AWD Hatchback model.
I recently noticed that it's been squeaking a bit. But only right at start up. In fact, it's summer where I live, and A/C is required just about anytime you go anywhere, day OR night... so, it may have been going on a while without me noticing it. Certainly sometime since the last oil change (almost ready for a new one).
Tonight was typical..... Start the car. Back out. Drive half a block to where there's a stop sign. I hear squeaking when I step on the brakes. Take my foot off the brakes (just to test it) and I still hear squeaking.
I turn left from my side street onto a busier street, hear a bit of squeaking. It goes away. Then I go two more blocks, make a left turn onto an even busier street, where it squeaks LOUDLY while turning left. By the time I drive another six blocks, the noise is gone. Completely.
At first I wondered about the summer heat and the serpentine belt.
The squeaking while turning left made me wonder if it's a stuck caliper.
The fact that it goes away after about a mile of driving makes me scratch my head.
Tonight, I did experiment a little. The car DOES pull -- EVER SO SLIGHTLY -- to the left. But I mean.... just barely to the left. And that could've been because the particular road I was on (when I "over corrected" a little and aimed the steering wheel a lot more to the right, it started to drift right). Alignment was last done a little over a year ago. Maybe year and a half.
So...... I know I should get this checked out. Just looking at what this might be. The fact that ALL squeaking goes away after about a mile of driving.... that seems odd to me... (unless of course it's the belt).

I'm having an issue with my fans on my radiator. They don't turn on when the engine gets warm and the A/C is off. I've replaced the crack pipe, water pump, and belt tensioner. I've replaced the fans not to long ago because the low speed wasn't working. I tested low speed at the fan connector and it wasn't working. After replacing fans I tested and it was working when jumping the pins on the thermo switch connector. I got both low and high speeds to work during that test. I've since replaced the thermo switch to see if it would fix the issue but the fans still won't come on without turning the A/C on. Any other tests I could do or should I just try to get another thermo switch.

My car has 130k miles and has recently developed a worrying noise. It makes an extra whirring sound, like another set of gears spinning, but I don't think I would describe it as a grinding noise. I live in VT and I thought maybe it was my (studless) snow tires making more noise in the warm weather because I noticed it about a month and a half ago when it warmed up. Now that I have my all season tires on, it's still making the noise. The tire guys didn't notice anything wrong when the swap happened (but they only do tires there and I didn't ask them to look for anything).
As far as I can tell it is dependent on wheel speed, not engine speed. It starts at about 20-25mph and gets louder the faster I go. At about 65 the normal road noise is louder than the new noise. If I turn the wheel to the right to any degree the noise goes away. I can't tell if it is completely gone, but it seems like it is. There is no real change if I turn the wheel to the left, though it might get slightly worse. When the noise is going I can feel a vibration in the floorboard that matches the sound. The sound seems like it is coming from in front of me, but I can't really tell if it is left, right, or center. As far as I can tell that is the only new noise, no clicking/griding when I turn the wheel etc.
I'm taking it in for normal 130k maintenance in a week....

2001 Jetta GL, 2.0L, 170k miles.... It won't start and it's not likely the fuel pump. After the car has sat for a while, I hear the fuel pump spin up when I open the door. It turns over just fine. I pulled a spark plug, attached it back to the wire, held it close to the head, and when the engine turned over, no spark. Is that still a valid test for spark? I haven't had to diagnose a spark issue for so many years, I don't know whether that has changed.

I have Golf MK4 1.6 16V BCB '02 and problem while engine is running on idle. Engine works at 1100 rpm (doesn't matter is it cold or warm engine) all the time.
Dashboard turns CHECK ENGINE and EPC lamps and says : "engine workshop". At the beggining of problem VAG-COM diagnostic found this error:
17953 - Throttle Valve Controller: Malfunction
P1545 - 35-10 - - - Intermittent
But after I've changed my old throttle body with new one VAG-COM diagnostic haven't reported any error (no permanent error) and idle issue stays.
While engine is running and Check engine and EPC lapms are turned on diagnostic reports this error:
17961 Barometric/Manifold pressure signals: Implausible Correlation
P1553-35-10 ----Intermittent
After engine is turned off diagnostic doesn't report any error!
Beside of changing throttle body, I've changed ECM, MAP sensor, temperature sensor, EGR valve, . Also checked intake manifold and hoses if is it leaky (doesn't leak anywhere), and timing belt is ok and checked complete wiring installation!!!

I have 2002 2.0 Jetta that I totaled. I found a 2000 2.0 Jetta that had no engine or tran. I swapped the entire wiring harness with the engine and trans from 2002 into 2000. I even swapped the doors. The cluster, steering column and all. I am still in the process of getting a few parts to finish it up. At this point, the only thing not hooked up is the headlights and the radiator. I hooked up a battery and tried to get it to turn over today. I turned the key to the on position and the cluster did not do anything. The engine turned over very slowly in the start position.

When the sunroof is open all the way, as soon as I reach the speeds of over 25, there is this annoying Wind noise that kinda hurts the ears. It goes away if I crack a window open slightly. I've test driven other cars (bmw 3 series) and there was no wind noise. It's not a big problem. It's has probably has something to do with laws of physics?
