Golf IV / Jetta IV :: 2004 GTI - Popping Noise From Underside Like Muffler Came Loose
Mar 17, 2015
I was driving home and suddenly the underside of my car *popped* and it sounded like my muffler came loose. Very loud exhaust/turbo whistle.
Luckily I was very close to home and was able to pull in when it completely fell off and started dragging on the street. What part of my exhaust is this and what should I do to repair it?
I just finished fixing a ton of stuff on her and now she does this ?

My 99 Jetta is rattling. The noise comes from the front center of the underside of the car. It started out only when I was accelerating and would disappear when in neutral or after reaching 40mph. Now its when its idling and driving at any speeds under 40mph (I think it just gets drowned out above that speed). I looked under the car and saw that there might be a piece causing the noise but I can't figure out what it is. It seems to be in-line with the exhaust system and its a metal, cylinder looking piece that has uniform holes in it. I'm just trying to figure out what is causing the noise, if I can fix it easily or if this is going to be a pretty expensive fix. (It has 165k miles on it, is a 2.1 gas engine with the new body type).

After a bit of a crunch to the underside, i've noticed some circular metal covering broke back and some wires are torn and exposed just behind the front passenger wheel on the bottom.

For the last few thousand miles my 99.5 jetta has been making a popping noise (many pops, not just one) only when turning right under acceleration. (No noise when coasting or decelerating in gear and turning right, no noise under any circumstances). no pulsing in the brakes, and the car appears aligned well as it tracks nicely.
The noise is rotational, the faster you go, the faster the pops happen (again, it will make many popping noises, not just one). Probably once per revolution on the tires, not entirely sure. And it is, with as much certainty as i can have, coming from the front passenger side of the car.
I took it into the mechanic twice, first time they couldn't hear it and sent it back. Second time they said it was likely the CV joint so replaced both on the passenger side.
I have to admit that I didnt notice the noise for about 300 miled after that service, and I did try to get it ot happen. but its back now.
All boots and ball joints look ok and no grease has slung out. I am thinking it might be a wheel bearing at the extremely early stages of going.
Right now i am on a "wait and see if it gets worse " course. For the last 1500 or so miles it has not seemed to have changed.

After 1-2 mins I turn off my car I hear a popping sound from under the car. Usually it goes after some sounds of cooling down the metal and ticking, and then a pop sound. Nothing during the driving. I did some research and found that it may be Catalytic Converter cooling down or the heat shield.

I can't figure out what this popping noise is that is coming from under the car (towards the back, not from engine). Its infrequent and I only notice it at idle. If I had to guess it would be exhaust related, but that still doesn't sound right. What could it be? See the video below for the sound I am talking about.

2001 vr6 manual... I have a popping noise that comes from my suspension. it is in the front, and it has gradually gotten worse over the last month or so. It used to happen when i back out of my drive way only, but now it happens when accelerating from a stop, quickly braking or turning at low speeds. Recently its getting worse and i can start to feel it in my steering wheel sometimes. It doesn't feel like a wheel bearing. Is it bushings? Tie rod? CV Joints? Strut Mount?

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.

Ok a week ago i noticed a popping noise when i would turn my steering wheel while the car was parked. It sounded and felt like it was coming from the drivers side.
Now a week later i have a weird constant whirring/growling noise coming from the drivers side wheel area. Which only stops when I stop completely or take a right hand turn.
So I think its a wheel bearing due to the fact it stops when I turn right, but thats why im here im not totally sure.

Got a 03 GTI VR6 and my drivers door kept on making this creaking/popping noise(it is very similar to the creaking noise of a old wooden door or the sound you hear in horror movies but for a lot shorter duration). The sound seems to come up when I accelerate, break take off from a complete stop. I took the car into the dealership and they torqed some bolt on the hinge and the creaking went away. Not a month later the passenger door develops the same creaking. The dealer tries to torqe the bolt on the hinge again and they say it cant be done and that their body shop needs to replace the hinge. They paint a hinge for me and put it on but don't get the door adjustments right so I get a lot of wind noise. Finally they adjust the door right and all is well.
A while later the drivers door starts creaking again! I went to another dealership and did an oil change while I was away on a trip to Toronto and the service technician said he could lubricate the door gasket and that this will take the creaking away. So he did. Now granted that has taken the creaking away but after some rain and 2 car washes the creaking came back in full swing.
I call the dealership to set up an appointment and they refuse to look at the door saying that as far as they are concerned the vehicle is up to manufacturers specs and that they will need to get a VW rep to look at it. In the mean time I call the vw customer care which tells me that they contacted the dealer and that the dealer beleves that the car is up to manufacturers specifications and that the noise I am hearing is normal and that all the cars have this noise.
Now I owned an 02 Golf GL 2dr and never heard that sound. It's been a month and a half and neither the dealer or vw customer care have called to inform me when the VW area rep. will be coming to have a look at the issue. It looks like I hit a dead end with having my issue acknowledged and looked at. Is this really a standard noise on the mk4 2dr platforms ? How I should pursue this issue ?!? Anything ?!

when I bought my 2003 gti 1.8t it had a small exhaust leak, I decided to investigate today and found that the downpipe flange and turbo flange was rattling around, there's almost 1/16" of play and it's making a rattling noise. I can't tighten the nuts on the studs any more but that might just be from them being seized in place. I'm getting a new gasket and studs and nuts and hopefully that will fix it?

Putting a magnaflow muffler on the 99.5 2.0 slow jetta on Wednesday and I realized I don't have a rear GLI lip. Any single turn down extension off a muffler ? Or just run a straight pipe off the muffler ? Clearance with the rear lip issues ?

I removed the old muffler but it was severed at the pipe so there was no issue getting it over the rear cross member. I dropped the center brace to remove the resonator from cat back.
My question is, is it possible to install a new OEM rear muffler without a lift? I have stands but I do not know of I can get it high enough, or if I even need to get it that high? Not sure the bend of the pipe before it meets the resonator.

I am replacing the mid and rear (suitcase) mufflers on my daughter's 2001 2.0L Jetta wagon. She is not interested in anything that would be louder than stock. What I am seeing is that the rear axle needs to be dropped to remove / install the rear muffler. Can this be correct? I know I can continue to cut off parts of the old muffler but that does me no good when it comes to install the new unit.

Whilst driving on the motorway at the weekend I noticed a very load high pitched noise which seemed to be coming from the rear/centre underside of the car. It lasted for about 30 seconds and then went. It has happened before about two months ago and after the first instance I had the haldex and rear diff oil changed. On both occasions it has been very wet on roads with torrentian rain.

01 taurus pushrod motor. Vulcan? Today it started idling poor/ stalling. I can hear a popping sound from muffler. Almost like a coffee percolator. No codes. Motor seems quiet. No odd noises or metallic sounds. Friend says burnt valve? Last week or so I thought I heard exhaust drone on acceleration. Almost like a hole in muffler. But muffler is good, same as exhaust pipes. The perc sound is not rhythmic. Sort of uneven. Like a chugging/ puffing sound. Intake manifold leak? Upper/lower? This year does not have IMT. Intake tuner device?

I've had my car for 7 years now and it's a love / hate relationship. I probably put more money in maintaining the car than upgrades. So, I have the kw club sports, front and rear neuspeed sway bars, neuspeed front strut bar, and neuspeed control arms. I lost track of how long its been since I've been hearing this popping noise but it occurs almost every time i leave my drive way.
The drive way is not flat. It dips down then comes up to the street. When reversing two tires come of ground, the front left and back right. When that happens, something pops from the rear... Recently it has come to the point when i take a right turn, i hear a pop from the rear.(not all the time). I told my mechanic to check the sway bar bushings but apparently that not the problem. Suspension shocks and springs are fine.

Diagnosing a possible front suspension issue.
While backing up, I felt a springy popping in my car. I ignored it attributing it to just the freezing temps and kept on driving. After a few miles I felt something got loose and started rattling, but it went away after a few seconds. Maybe a nut got loose and dropped from the car? Anyway, the rattling is gone but during slow turns, I still feel popping or pinging. I don't feel this when driving at highway speeds.
Can it be the strut bearing mount broke ( see pics below)? Looks like the driver side collapsed? Would that explain the sound of something getting loose, that the mount actually broke?
Driver side
Passenger side

I have an 02 Jetta the the left CV Axle came loose from the tranny/axle flange. I checked the Bentley and it shows that a bolt holds the flange on, I guess a spline. My question when taking one off, is there anything inside that will drop/pop off when I pull it? The reason I need to take it off is that some of the bolts actually broke off, while others screwed their way out. Not sure why they came out or what made the others break but they did. It would be so much easier to get the broken bolts out with the flange out.

Recently i noticed that my gear stick is very loose. I have read that this is a problem with the linkage bushes. I have found that the bushes are in the engine bay (3 i think) but i was wondering if there are more bushes under the gear stick that i need to change. Looking for a complete kit for all the parts needed ? Do i have to change something else ?

So I just noticed now that my car is popping slightly at idle occasionally...It doesn't do it all the time and the idle is kinda lumpy but always holds at 800-900. Sometimes it drops a bit lower.
Also when starting it up in the morning, or when the engine is cold it doesnt rev up to 1500rpms it just starts and immediately drops to 800-900??
When I press on the gas and keep the pedal at one spot, say 2000rpms, it slowly drops down to 1500??
