Golf V R32 :: Siren Like Noise When Undercarriage Gets Wet Coming From Rear
Jun 3, 2015
As described, It presents when the rain is heavy and I splash the undercarriage with big amounts of water, then this very strong siren-like noise comes from rear and underneath the car. Once the car stops or undercarriage is no longer being showered by water from the splashing on the road, it quiets and stops. While present, if I stop the car the noise goes as well.
Some of my searches on google have come to other car forums and they are all seem to be happening on AWD cars, some blame the exhaust is affected by the cooling down effect of the water.

Well this week, everytime I was backing up, hit a pothole or sometimes when I turn either left or right or hit the brakes a clunky or sometimes metallic sound appears coming from the back the undercarriage.
First I thought may be one of the bars (TRD or the Ultraracing sway bars) were loose, we lift, checked the car with the guy who installed the bars and all of them were tight ,nothing loose, we discovered on the front is time to change the bushings of the front stabilizer bar and also the rods who run parallel to the shocks absorbers but we couldn't mimic the sound the shocks are fine.
Tonight my daughter was driving the vehicle so I have a chance to hear the clunky noise, which I think is coming directly from the inside of the drums the sounds intensified at the time of hitting the brakes but is not all the time you hit the brake when it happened.
Also I can't explained why I heard the sound when I turn left or right and still coming from the back, doesn't make sense I can't find no relation whatsoever
I just add this 2 videos..

Our 2009 Santa Fe has a knocking sound coming from the undercarriage of the vehicle. It cannot be heard when parked or when coasting. If I gently depress the gas pedal enough to rev the engine to 1500-2000 rpm when traveling at speeds of 35mph or greater it can be heard. The rate of the knocking / thumping appears to be related to vehicle speed, i.e., the faster we move, the higher the knocking rate.
Yesterday I emptied the vehicle of all contents and was still able to produce the sound upon demand.

My 09 FX4 Screw has developed a strange thumping sound coming from the undercarriage within the last month or so. Very noticeable when turning on even terrain. It's just barely under warranty and I am planning on taking it to the dealer.

I own a 2004 Volvo S60 2.5T AWD. I have noticed that usually when I am driving and it starts to rain heavily, there is a loud siren sound coming from the engine area. This sound stays till it doesn't stop to rain. Also, if I don't step on the accelerator, the sound goes away. I have taken it to the dealership a couple of times but haven't been able to replicate the sound.

I've had a funny noise from the rear of my car for quite a while now. It's a snap/crack sound that comes when the car is twisted along its length, like something is releasing tension or something. For not quite as long a while, I've been convinced that it's a matter of re-used stretch bolts (I'm not the one who re-used them though) on the both ends of the shocks back there.
I hear this sound (sometimes I can feel it as well) when I angle out of my driveway, which slopes down into the street beyond. Must angle out to avoid scraping the nose, and must TURN into the street anyway. Maybe under those conditions something shifts a bit. I have a UNIbrace; I know that's not got anything to do with it (I had it out for a bit to test).
Have new upper and lower rear damper bolts on hand. but probably worth it even if this makes no change. (Rule out the easy, inexpensive things first, they always say). My Bentley notes "spring must be removed before removing shock." I'm sure this is because the springs keep pressure on everything nearby and we don't want to release that suddenly by yanking the shock out. Or trying to.
If I have the rear of the car on stands and aim to do one side at a time, I can place the pad of my floor jack underneath the trailing arm back there, jack just a little to sort of "hold" the pressure on everything and remove/replace the bolts easily.

Got a weird "howling" (best description) noise coming from the rear. Only happens when letting off the gas. As soon as I start to accelerate it goes away. Let off the gas it comes back. Started Saturday.

There is a humming noise coming from the right rear of my R, I'm going to guess that it is the furl pump running? If not I don't know what it could be, or if usually that loud...
Second, I was thinking of getting adjustable rear control arms. I was going to get just one set, to adjust the camber to 0.0 instead of the -1 or so that they usually ride.
Third, I was also contemplating getting upgraded motor, trans, and dogbone mount. I was told it would cut down on transmission noise while letting off the gas pedal whence driving.

When running and nothing is on (speakers/ac/ heater), I recently started to hear a sound under the rear seat closer to the passenger side. Not sure if its new, or if I just never noticed it before.
The best way I could describe it is as a hard drive or disk drive that is spinning or constantly seeking, but loud enough to hear at all times if I listen for it..
Its faint but annoying when idling or at low speed. The noise never changes pitch or frequency under power or or breaking.

Is this much water supposed to drip from the undercarriage if you've left the car running for maybe 10 minutes without moving it, while the AC is on?

So i have recently started hearing a noise coming from the rear of my car when i start it in the morning. When i fire my car up and sit in it for 10 maybe 20 seconds it starts making like a clunk/chug/thud/pumping sound? i fear its a sign that my fuel pump is going bad? After about another 30 seconds or so it goes away. It only happens when i fire it up in the morning probably because it has been sitting there for so long, but it won't do it lets say when i get out of work 8 hours later.
And another thing is i was looking for solutions for all the other creaks and cabin noises and sunroof rattles but the link is broken and I'm going nuts chasing these noises with minimal success. My passengers door/area sometimes does not make a noise for a few days but sometimes it sounds like there is a million turkeys chasing gerbils around for weeks!!
There is a clunking sound coming from my passengers door (i have taken off the panel and looked for loose connections with no success everything looked good). My headliner/sunroof chatters.

So I'm driving to work and as I slow down to pay the toll I hear a weird grinding noise from the rear (sounds to be rear right) get out and check the crime scene. The plate is not rubbing on the rotor and there is nothing stuck between the rotor and the plate, so then i check the pad and they look pretty low, check the other side and looks the same, check the front and they r good n meaty. So can this mean I need new pads? The grinding noise goes and the car goes, the faster i go the faster the grinding noise goes, as i slow down it slows does..
Wanna make sure I get the problem right so I can fix it since I'm doing a Haldex oil service cause I also have the binding noise and then i gotta get the coolant flush done... hope all I need is pads... The noise goes away when I brake.

WRD Coilovers on my MK4 GTI. I finished my install this evening, and on my first test drive I noticed a knocking noise in the rear. I believe it is the springs sitting a little loose. The front of the car is sitting a bit lower than the rear, so I believe most of the weight is shifted towards the front, therefore making the springs kinda free float? I jacked her up after the drive and kinda gave the springs a wiggle and they have a tiny bit of play, enough to hear the spring kinda TING against the perch. I suppose I'm going to raise the front a bit to try and distribute the weight more evenly.

I am getting this weird clicking/ticking noise coming from the rear of the car. I might have to let someone drive the car and follow and listen for myself (but i dont like other people driving my car), but its definitely coming from the rotation of moving.
It is audible moving forwards and reverse. It speeds up as the speed increases. It comes from the passenger side and can hear it mostly from the sound bouncing off things from the outside. I cant feel it, its just an annoying sound. I still hear it while applying the brakes. Sort of sounds like flicking sound. Pads have plenty of life and changed my rotors about 20k ago.
I've read somewhere about brake pad spring busting but its still audible when the brakes are on so I don't think that's it.

Started up my car this morning and drove to the gas station. I had the car on low fuel, got the low fuel light last night but didn't have time to stop by a gas station to fill up. Anyways after I did finally fueled up this morning, I pulled out of the gas station and a very loud squeaking noise which sounds like metal on metal occurred. The noise is coming from the rear, but it's really loud, nothing I have ever heard before.
I will mention that I have Koni coilovers installed, tried to peak under the car and see if something broke or came loose but I was unable to see anything since I am sitting pretty low.
I live in Chicago and this morning was very cold. I am trying to figure out what my issue could be. I called up the dealer and he told me to drive it around for a bit and see if it goes away. Another guess would be that something got stuck between the rotor and the break pad. I have the stock break pads. What could it be?

Watch this video. I have a rattle/noise coming from the rear right side of my car for almost 2 years now.
The part in the video is the neck of the fuel tank just behind the plastic inner fender.

Is this normal? i don't know where to search anymore to find where the rattle comes from...

so my r32 recently started making a nasty popping noise. the sound seems to either be coming from something in the rear end or drive shaft. not sure why it happened. i went on a 2 hour trip. got there parked it. aired it down (bags) but then when i came back and when to drive it again. it all of a sudden it started making a horrible popping noise. i thought it was the front wheel bearing going out since i knew it need to be replaced but i did that today and its still making the noise.
The noise sound just like a RWD car with a welded diff when it turns. kinda has that locked rear end hop popping noise. i lifted the whole car off the ground and put it in first to let the tires spin in the air but of course theres no weight on them so it doesn't make any noise. i'm really stumped on what it could be. im going to take the driveshaft off and see if it still dose it. then i know its for sure in the rear end. What it could be?

Just had my 40k service done, and also got an alignment done at the same time. On my way back from the dealer I noticed a knocking noise coming from the lower rear area of the car which is more noticeable when going over bumps. Its intermittent. Thinking something got messed up when they were doing the alignment? What this might be?

When I do a cold start-up and after about 5-10 seconds after start, I get this clicking noise coming from the rear passenger side. Almost sounds like something maybe gas cap is trying to lock or something. But when I hear this noise and even unlock the fuel cap I still get the same noise. I cant figure it out for the life of me. I even unlock and open the rear hatch... same noise. And after about 20 seconds of this noise then all of a sudden it goes away.

Turbo leaking? Is it costly to fix? I have a 2002 Passat, V-4 engine. I just took it in to get my oil changed and the mechanic told me that there's turbo leak. I have also been experiencing a weird siren like noise when I drive and the car feels like it's struggling whenever I go over 40 mph and or driving up a steep hill.
