Passat (B5) :: Metallic Chime And Rattling Noise?
Jun 29, 2012
I am a brand new VW owner and new member of this site. Just recently I purchased a '02 Passat GLX 4motion (w/97k miles) for fairly good price knowing that it was involved in a rear end accident.
Now I am finding multiple issues with this car. It looks excellent from exterior or interior. I have three different issues (front and rear axle pinion seal leak, broken spring, gas leak only when tank is full) with this car but I would like to discuss the Broken Spring issue here.
When I go through rough road or bumps I hear a metallic noise (noise like key chiming) from the rear driver side along with a rattling noise (like wood or plastic board rattling) at the same time from the rear middle part of the car. I researched online and found few forums talking about the brake pad caliper spring making similar noises. I called a mechanic and I was told that it could be the muffler.
I took the wheel off and kicked and hit the axle area with rubber mallet, kicked the muffler - but no similar noise was produced. However I noticed that the spring coil (rear driver side) was broken right at the bottom. When I did online research I saw one forum talking about broken spring making similar noise. I did more research and found the part (OEM# 4B0 511 115 B).
My question is:
> Does this sound like what causing the noise? Could a broken spring cause metallic chime and a hard board rattling noise?
> Is it necessary to replace the spring along with the shock absorber? Can spring be replaced by itself?
> How hard is it to replace a spring?
> Do you have to have spring compressor to mount and unmount? Can you simply take the whole assembly without compressing it?

While driving through a tunnel today I noticed a metallic rattling noise upon acceleration. It goes away immediately when I let me foot off the gas and when I park the car and rev the engine the sound does not occur.
A few days ago, I had to rapidly accelerate and it felt as though I lost power for a split second. I am not sure if these are related, but I am hoping its not some sort of transmission issue (unless that is covered under the hybrid warranty. What was the diagnosis?

My '99 Legacy is far from quiet, but yesterday I heard a new -- and somewhat alarming -- noise.
Roughly two-thirds of the way through a four-hour drive, I started to hear a rattling or grinding sound coming from the front of the car, perhaps closer to the driver's side than the passenger's. It sounded as if a tin soup can or paint can were hitting the road, but when I popped my head under the car, nothing was hanging loose.
I hear the rattling sound as I begin to accelerate, and only when I have my foot on the gas -- when I let off, it's perfectly quiet. What I haven't been able to determine is whether the noise goes away after I reach a higher speed, or whether the sound of the usually loud engine drowns it out. The noise is most acute around 1500-2000 rpm whether it's in gear, or whether it's in neutral and I'm revving the engine.

My R32 has got about 9,400mi on it, and for the past 3k miles or so, i've been dealing with this metallic scraping/rattling noise coming from underneath the car. When I took it to the dealer, they said it was the exhaust flex pipe, so they replaced it under warranty. Next day after picking the car up, same noise. So i took it in again this morning and they are saying its the flex pipe again, and they don't know if it is fixable.
They are talking to VW tech assistance, and trying to figure something out. I really love this car, but if VW says there is no fix for it, I'm weary about possible future issues without fixes too. Apparently it has something to do with the length of the flex pipes and the material its made out of. He was saying one possible solution is stiffer engine mounts. We'll see where this goes.

My truck is making a metal on metal rattling noise when going over undulations or the type of vibration when you drive over a rumble strip.
It seems to be coming from underneath the engine area, but not quite sure. The sound is like a kettle lid clanking on the actual kettle when the water's boiling if you can hear what I mean. No noise when just driving.

Noticed a weird metallic rattling noise coming from the transmission when switched to N with the engine running and the car is stationary? Almost like the gears are rattling inside while in N position. I took it to the dealer and their Prius guru said this is normal characteristic of eCVT....

I've been hearing this rattling, sometimes kind of a metallic ping, from the rear the last week. I thought it was probably the universal joints, didn't do it often, only under load between 1500-1900RPM roughly in second, third and fourth. I planned on working on it this weekend.
Today it started really making noise, sounds like valves rattling as though the timing was too high but it was coming from the rear end. It was making it all the way through the gears into fifth, even when cruising. Once it cooled down a bit it nearly went away.
I'm going to get started on it as soon as I can, but I can't get it in the shop to pull the differential cover and take a look right now. Dad's shop is full of crap, I live on top of a hill, not many safe places to get one up in the air properly. What is causing that sound?

Usually happens after car is warmed up. Rattles only while stopped and transmission still in drive. If I shift into Neutral or Park, rattling stops.
Last time I had a problem similar to this, dealer said it was a heat shield making the noise and they said they removed the heat shield (didn't specify what the heat shield was for.
Now I'm wondering if the heat shield was removed, what else this could be now...planning on taking it in in a few days.

I'm having a problem with my Prius. It pings under acceleration and it sounds like something metallic is rattling. It only happens when I use 87 and 89 oct. I use 91 premium to reduce the ping however, gas prices are rising and I want to go back to 87. There are no warning lights or anything and the ping has been happening for quite some time now.

When accelerating up a steep grade the engine will ping (rattling metallic sound) when reaching a certain RPM, but stop pinging as I continue to push the accelerator down and increase the RPM. Should I be concerned? Could it be something else, loose exhaust heat shield or something? Or is this normal behavior for a gasoline engine? My old Honda Fit never had engine ping/knock that i can recall in its 200,000km of service running the same 87 octane gas.

Driving an '03 Hyundai Elantra. I've noticed that occasionally when turning and also when driving at around 55mph or so, there is a metallic rattling sound that seems to be coming from the front driver side of the car. What this could be?

My 2002 Dodge Grand Caravan has a sound metallic rattling at about transaxle area (I am not sure if it's a transaxle issue) when it's cold but when it's at operating temperature, I don't hear it anymore. Fluid level is correct and clean, I just have the fluid changed. Shifting is fine, just annoying sound, not loud but it can be heard easily.

I've recently been having a metallic creaking/rattle go on when idle or moving at slow speeds. I took it in during my 20k service and they said there was something with a cable and the heat shield... the service manager had also said something about the catlytic converter - but when I re-checked the service slip - nothing. This was originally in March.
The noise came back again recently so I had a different dealer check it out when I finally had the fuel tank recall done. They confirmed the noise and checked the heat shield (I had told them about the original complaint), but said there wasn't much that can be done - they made sure all the bolts were tight, but the noise was coming from the heat shield "flexing."
Most of the time it's fine and the noise went away for several months. It's subtle again, but if it becomes constant - it seems like I have a valid argument to have the heat shield replaced - seems defective.

Front end makes metallic rattling/clanking sound. This happens when I make a right-hand turn, and the noise comes from the left-front wheel area. I describe it as the sound of dropping a handful of pots and pans.

Tis the first of "Squeaks and Creeks" from me. Not really the best thing to hear, sitting at ~24K miles. Anyways, until (if) i can get a sound clip, I have this metallic rattle that only occurs about 1-3 mins after i start the car. This just started happening yesterday, and nothing out of the ordinary happened.
I start the engine, hear a raspy rattle from what sounds like under the engine, and if i give it some throttle it increases some, but not to the point where it sounds like something is banging around. It goes away after a few minutes so it could be anything. Shifts are still smooth, driving and getting on the gas does not fix nor make it worse, either in neutral or actually rolling. It simply goes away with 3 minutes time or so. It seems to have a limit for how much 'rattle' it gives off, and its something I can accept.

Problem description: A loud metallic rattling sound from under the car under moderate to heavy engine load, only when engine/exhaust is/are cold. It is noticeable from within the cabin with the windows rolled up and the sunroof closed. Crack a window or the sunroof and it's pretty loud. The first time I heard I, I thought "this is not good".
This is not an octane ping or valve train noise. It sounds like a coffee can with marbles being shaken in concert which what might be the rapping of a V8 engine's exhaust. I had a Sunbeam Tiger that rapped in the upper rpm ranges and this reminded me of that but instead of rapping, it shakes a can with marbles.
There has been much discussion and speculation as to what causes this. It does seem to occur only with late - 04 and up V8 Touaregs with the "sport" exhaust that replaced the "std"(?) exhaust used on the majority of the 04s.
Observation: I looked very closely at the heat shields, looking for ways they could rattle. On the passenger side (LHD), the heat shield has three main sections:
- Front: around/near the secondary cat (tightly secured)
- Rear: around/near the rear differential (tightly secured)
- Middle: between the two mentioned above (loosely secured)
The three sections overlap a little where they meet. It was very easy to tap on the middle shield and make a loud metallic sound. I put my finger between the two shields (where they meet) to isolate the two metal pieces and tapped again, and the noise was gone.
Theory: The harmonic resonance of the exhaust under load vibrates the middle heat shield and it rattles against the front and/or rear shields. As the shields heat up, they flex enough to provide clearance between each other and the noise goes away. This may be unique to the "sport" exhaust if (and I am only speculating) the heat shields were changed (in design or fitment) when they changed the exhaust.
Experiment: I tried a very simple experiment. I slightly bent the edges of the middle shield (~1/2 inch) where it was coming in contact with the front and rear shields. The allowed me to tap rather hard on any of the shields without them rattling against each other.
Result: I make the tweaks to the shields Sunday night. When I drove to work this morning, I put the transmission in sport mode and ran WOT until it shifted. Normally, I would have heard the sound (very loudly) but it was gone. No metallic sound. Not completely convinced, I repeated the experiment on the way home and, again, the sound was gone.
Summary: It was cool out when I was going to, and from, work (64F) and this would normally be the perfect set up for making the sound. I think that tweaking the heat shield has solved the noise on my Touareg. I am tempted to go back under there and pop-rivet a little brace between the shields so that they cannot rattle against each other again. On the other hand, I may just leave it be and do the pop-rivets if the noise comes back.
Anyway, I was excited to find a potential solution for my Touareg and wanted to share it will you all. I will post back after a while and report how it goes in the long term. Lastly, I really liked being able to put the air suspension in xtra-offroad and get under the car (easily) without using a jack....

Recently I started hearing a rattling/grinding metallic sound coming off the right rear while driving slowly. This sound is not reproduced when braking.At first it started while doing sharp right turns only, now its ever present while driving. I showed it to a mechanic he says rotors needs to be replaced. Is he right? 2003 Honda Accord V6....

I have had my car at the dealership once before for fixing some rattling noise in the cabin. That was a couple of months or so ago. The rattling is back again, this time from the front doors area and from the front speakers or dash area near the speakers.

I am getting a weird noise from the front suspension on my car. I recently about a year ago installed DG springs it did this a little before I replaced the springs but now its louder. it sounds like either a mount is loose or something is broken. I live on a dirt road so I hear it a lot on the small bumps. could it be the upper strut bearing? or the fact the coils are shorter? I have 112k on the clock and Id like to take it to willow springs soon but am concerned about this. One more thing it doesn't drive weird..
