Golf IV / Jetta IV :: 1999 - Rattling Noise Comes From The Front Center Of Underside Of Car
Jun 4, 2012
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).

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.

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 ?

So, I have discovered my first rattle in my GTI (8500 miles). Seems to be from the underside, sounds like a heat shield rattling, certainly sounds metallic. Did some spirited driving yesterday and hear the rattle today. Any target areas to check when I take a look under it?

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.

I finally took my car in and the technician drove around with me. He confirmed that the noise was coming from under the dash. After some discussion with his supervisor, he came back and said it was the insulation pads which had broken down and needed replacing. He said this was due to the heat. He told me this involved taking off the dash board and was an all day (8 hour job) of about $800, but they would charge me only half, about $425. I was stunned because I have never had this happen in another car. I use window shield and keep my car in a garage most of the time. It does not sit out all day by any means. So I am looking for solutions before I go back and say that it seems this should be under warranty. I purchased the extended warranty when I bought the car new, but after reading over the packet, it does not seem to cover insulation pads in the dashboard. I love the car, but it is really annoying when we are driving around town and have a constant noise from the dash.

I own a MK4 Golf GTI which has recently started making a rattling noise when I first start the car (Perhaps cold weather?). It will continue for roughly a minute despite load (A/C, acceleration) before It stops and It won't happen again until the car has cooled down hours later. It's quite an unsettling noise and I would like to be set in the right direction.
After a couple hours online I'm leaning towards perhaps the belt tensioner being to blame? I haven't delved too deep into the noise but do believe it is from the left side of the motor. Can likely clarify on the weekend.
Is there anything to worry about? If so, where do I start? I myself was trying to fiddle around and see if the noise would happen at higher revs, which it seems to. [URL] .....

I would really want to know what is causing this sound as it has become louder.
The noise can be heard in this short video: [URL] .....
The noise is coming from the area of the pulleys, and can be perfectly heard behind the passenger side front wheel.
The car is an AWD 1.8T Golf 2002 model.

I have a 2003 1.8t jetta. I got it in the fall and never really needed to turn on my AC until this week. It works, fans work at all speeds, blows ice cold air.
But i noticed today that my fans can be on and nothing. But when I hit the AC button there's a loud rattling sound. Everything works. It's just making noise when the AC is on. Whenever I turn it off the noise goes away.
I tried looking it up and couldn't find anything.

Yesterday i had taken my front grill off, 08 R32 including the bottom sections where fogs would otherwise be since you have to.... Anyway, i did all that to get my euro plate secured on my grille. Now I'm hearing a rattling noise when I go over a rough surface or descent sized bump. Everything with the grill is clipped and bolted back in tightly, any other things that could be causing this?

I'm new to the VW family as a couple weeks ago I purchased a 2003 VR6 Jetta. So far I LOVE it and it's been by far my favorite car I've driven. About a week ago, I was visiting my parents back home (I'm a college student) and when I went to turn on my car to go back to school I received the alternator workshop message. I didn't want to take the risk so I took my sister's car back to school and my dad took my car into a local mechanic during the week.
Unfortunately, the mechanic we took the car too does not specialize in European cars (They're just a general mechanic/Ford dealership), but we didn't want to take the risk of driving a car with a potentially failing alternator to the closest VW mechanic (About 40 minutes away). The car was repaired and a new alternator added. All was going well, but I began to notice a slight "clunking" noise when first accelerating/lifting my foot off the brakes. I didn't think too much of it and it wasn't very loud nor severe. To me, it sounded like the interior plastic shifting when I moved.
Anyway, here I am a week later and I'm noticing a lot of noises that didn't exist before, including the clunk I just mentioned. I took a few audio recordings. (For the record, there is NO CEL or any dash lights currently on, thus why I'm not as concerned).
The first audio: [URL] ....
In this link, I'm driving the car around the parking lot in which I park my car here at school. It's mostly bumping gravel, but at the time of the recording I was driving very slow. You can hear a squeaking noise.
The second audio: [URL] ....
In this link, I'm revving the car while parked. Something I've noticed that it didn't used to do is rattle while idling ever so slightly (It's not audible in the recording), but in the recording you are able to hear a slight clunking noise.

I did my pads and rotors this weekend. On the fronts I had some difficulty with the passengers side retaining clip. It was stuck in on the bottom. I wound up bending it out of place trying to get it off, and eventually just removed the caliper without it.
I took it out for it's first regular drive today and there is a rattling noise when the passenger's side goes over bumps (could be front or back, hard to say). I have theorized that the clip is deformed enough that when it gets jostled, it bumps out onto the rim which makes it go twang (which would be consistent, it's a relatively high pitched rattle. I'm going to look at it tomorrow, but I'm not sure what I should actually do. Can I just clip it off? What purpose does it serve? I might be able to get it out with WD40 and bend it in to shape.

Mk4 12v vr6 afp. 170k ish. No real mods except a cleaned up bay. Was death knocking LONG before I started the bay. Probably 6k miles. My car knocks/rattles bad in low rpm but promptly stops all noise at 4k and up. Makes the noise in any gear but only when throttle is applied. Even does it when revved up in neutral. No CEL other than one explained later.
Suspecting wrist pins as con rod bearings are brand new (replaced for no reason they were fine) and i removed head and no problems were found. Lifters tick a bit but that's all. Cleaned and put back with new headgasket. Shined up the pistons of course. Timing chains also done. <10k miles on oil pump. I even tried taking the shifter rod completely out and driving to verify if that was the rattle and no change. What could be left mechanically?
I was afraid the noise was preignition because I was getting codes for knock sensor out of range, so I replaced the knock sensors multiple times each, coil pack, wires, new ngk bkr5e plugs gapped correctly, fuel filter and pump. Have ran multiple tanks of premium 94 from different stations as well.
The ecu pulls timing back to 0 btdc and it is still knocking so I just decided that the knock sensors are picking up a mechanical knock rather than pinging. Only thing left is wrist pins or piston slap. Maybe injectors causing a lean condition?
Here's a pic of my car for attention ....

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?

Ok so I bought this 2012 f250 and I had a couple questions.
1. I checked the Frame for rust n it was fine. I didn't look at the other parts until I got it home. It does have some light to moderate rusting on other areas under the engine compartment. Ex axle, drive shaft, some of the steering components. Exhaust Manifold is pretty rusty though. What can I do about that?
2. I noticed a little bit of oil, not dripping, on the underside of the front of the engine. I do have an extended warranty so i hope it will cover that. It's pretty extensive of a warranty. I took some pics of the area where there is oil. What could it be?
Most of the oil is focused around there ...

I have a 2003 F-250 6.0L 2WD and I recently noticed a rattling thumping noise under the front end on the passenger side. I noticed the rattle shortly after I got new tires, which are a hair bigger than the tires I had on it before. I thought it might be my new tires rubbing since they were bigger but then I noticed the rattle when I had my wheel straight and also when not moving at all. I've been driving it for a couple of weeks now with this rattle and I've been able to determine that it rattles most when I am going downhill and turning to the left putting more of the weight of the truck on the front right suspension components.
After reading several threads my first attempt to find the problem lead me to the discovery of a worn sway bar bushing. I thought this was for sure the problem and replaced both bushings and end links. But the rattle didn't go away. Then I thought maybe it was a bad wheel bearing so I replaced the wheel bearings in both front wheels. Still no change. Lastly, I happened to find a loose ABS line in the front right wheel well that was no longer secured and was banging against plastic. I secured that and still no change. All the bushings seem to be in good shape so I am considering taking it to a mechanic since I don't want to just replace everything hoping that it solves the problem piece by piece.

My 99 F250 has just recently started making a "rattling" noise. The noise sounds like its coming from the front left wheel area. The noise is constant while driving down the road, its NOT created by bumps or anything, its a constant noise while moving.

Issue: rattling/clicking noise from passenger front wheel area at speeds lower than 15MPH, made worse under light braking and/or turns to the right.
Clicking sound is speed dependant.
Spindle? Hub? Balljoint? Sway joint? Rotor Issue?

I have a rattling noise coming from the front suspension (both sides) when going over small bumps. Most people point to ball joints, but I find my case odd because I just replaced
Upper/Lower ball joints
Track bar
Tie rod ends
Shocks
Front U joints
Drag link
I did not touch the leaf springs or the sway bar, except to grease the links, which otherwise looked good.

My car has been acting odd recently and I didn't notice until a romp down a local twisty road. Under acceleration or braking there is a knocking sound almost as if the subframe is moving. You can feel it through the steering and pedals. Also around tight bends when applying throttle there is a vibration followed by a clunk and then harsh vibration. The best way I can describe the feeling is as if I rolled a tire off the rim. I've read through all the tech guides and nothing has fixed it. I have new driveshafts, New tie rods, New steering rack. Everything underneath seems tight and the rear torsion beam seems fine.

Okay, I'm driving 35mph and i feel this bad shake. I go to Les Schwab(bad choice) and they say wheel bearing. Okay so I replace both of them. After that, I'm stoked get in my car and same crap. Im pissed at this point so i am now thinking CV joint. but it could be the inner jv, in the tranny, or something else.
