Elantra MD (2010-15) :: Strange Noise When Accelerating With A/C On

My 2012 Elantra has been nothing but problems. Unfortunately, with me being away from home in the USA, I haven't been able to bring it to my dealership. Lately, I've noticed that the acceleration of my E sounds different with the A/C on. It's more noticeable right when I hit the throttle that the engine engages, and power goes to the wheel. The sound is a deep more drone like sound, and is only there when my A/C is on.

Ford F-150 (2009-2014) :: Strange Noise During Accelerating

This has happened about half a dozen times while accelerating. It sounds sort of like it's between a scratching noise and a rattling noise. It's only happened at highway speeds 50-60 mph while accelerating and will stop when I let off the gas. There have been a few times that i can get it to come back if i step on the throttle again, but will not duplicate every time.

Golf VI R :: Strange Noise While Car Is Stationary

When the car is in neutral or in gear at a standstill there's a noise right around 1000rpm that sounds like a serious rattle or knocking. It sounds as if the car is puttering out. So essentially, I give it gas to around 2000 and then take my foot off and on its way back to idle it will putter at 1000rpm.

If the clutch is fully depressed or fully disengaged the noise is no different. I haven't noticed the noise in any other situation other than when the car is stationary but it's still a very disconcerting noise and likely just being drowned out by other noises when moving.

Does this sound like something engine related or could it be DMF chatter? Could I possibly pick up on an issue by running tests or logging with VAGCOM?

Some background on the car:

-Modified with APR Turboback and Stage 1/2 file 1.3 (the noise is present with and without tune file)

-I run 93 only

-Most miles are highway miles, currently sitting at 23k miles

-I don't notice any issues with shifting, albeit some slipping when tuned in 6th gear (no slipping when using stock file)

Golf IV R32 :: Strange Choppy Noise From Motor

The R has 48K miles on it. The other day i realized after driving it, a choppy noise coming from almost directly under the spark plugs. As the car was cooling down while still on the noise stopped for a few seconds and then started again. Any clue of what this might be?

Golf IV R32 :: Strange Noise Continues Even When Car Is Stopped

So as I was driving my R32 home today, and as I came to a stop, it let out a crazy groan/noise.. It continued even as I was stopped. At first I thought it was the brakes just making noise since it was raining. The pitch of the sound was much different than a brake squeal too..

The only thing I can think of is I parked overnight under a carport, which that and the driveway is a decently steep grade.. Maybe its e-brake related? However I just changed my e brake cables.

The car drives great still. I drove 60 miles then it made that noise. Also I checked on a dirt road to see if my haldex was still working.

Golf IV / Jetta IV :: Car Was Making A Strange Noise

So for the past few months my car was making a strange noise under my car, it turned out it was the dogbone bolt that stretches to the bottom part of the transmission. Some how it got loose and was literally hitting my transmission. So we tried bolting it back on and won't screw which was kind of scary it had some type of play. Do I have to get a new 02m for a little ass bolt, do I weld it, or is there a subframe piece I can buy to replace the Broken part of the transmission.

Golf/GTI VII :: Strange Noise Coming Intermittently

Just bought a '15 Golf TSI S/sunroof with the 5MT (night blue, for the curious). Anyway, I've been getting a strange noise that was not present on the test drives, but that I first heard driving home from the dealer about a week ago. Since then it has happened intermittently, and not reliably enough that I've brought it back to inquire about. It is hard to describe, but sounds something like a whir and whine together. Typically it starts when I am in gear -- 4th, usually, though I can't figure why that would matter -- and then take my foot off the gas. If, however, I put the clutch in or put my foot back on the gas, it won't stop right away. It does stop when the car comes to a full stop. I'm beginning to suspect that it happens more when the car and/or the day is very hot. The times I've heard it most often, it has been over 90* outside, and the car has been driven for at least about 10 minutes.

I drove around for 25 minutes this morning and it finally did it, so I hit the sound recorder on my iPad. For reference, this morning it was about 81* out.

Here's a video link to it. It occurs at the 1:13 mark, if you want to skip ahead, but it's pretty faint over the background hum. The sound is clearer on the actual recording when I play it back on my iPad. [URL]........................................

Golf VI R :: Strange Noticeable Noise When Go Into Reverse

So most noticeable is when i go into reverse. Initially it makes a loud clunking noise until the car begins moving then it stops ( sounds to come from right under the middle of the car, middle/front). Nothing like this in 1st from a slow start. But Another different noise between first and second when accelerating hard.

As I go to shift from first to second there's another louder clunk in between shifts. It almost sounds as if my seat wasn't bolted down tight and was moving. But definitely coming from under the car again, same spot...I just had a 42DD downpipe installed.

Golf VI R :: Strange Noise When Parking In Reverse

Canadian 2012 golf R. Build date 02/2012. 8500km ... Clutch sounds and feels weird since the beginning. But few weeks ago I started to hear a strange noise when parking in reverse. When stopped, clutch pressed, reverse engaged, then slip the clutch to move slowly and I'm hearing a buuuuuu noise for 2 or 3 seconds then stop.

When stopped, no gear, clutch pressed for few seconds then release : clac and like a grinding noise. Press clutch again, after maybe 1 second, the grinding stops. Also when driving normally at low speed, I notice the clutch is very noisy, looks like same grinding noise.

When I let the clutch slip a little bit to start moving from a stop, I feel a vibration. not only in the pedal but also in the car. The passenger can feel that.

Here is two quick videos ...

You will notice the "buuuuuuu" noise and also the grinding.

Golf IV R32 :: Strange Gurgling Noise From Gas Tank Area?

When I parked my car in the garage this evening, I noticed a definite "gurgling" noise and my first thought was that it was most likely coming from the coolant reservoir (even though it was cool outside and I wasn't driving hard at all before parking it). However, when I checked under the hood, it was obvious that the sound was not coming from that location (and the coolant looked OK/normal).

I followed the sound to the back of the car and it definitely seemed to be coming from the right (passenger) side rear area of the car (possibly the gas tank). I removed the gas cap but there was no pressure built up and the noise continued -- I also checked under the car and nothing was leaking anywhere and there was no odor of gasoline.

So, when I searched the R32 FAQ, the only thing that sounded close was that possibly is was the leak detection pump cycling; but the FAQ made no mention of a gurgling noise and there was none of the clicking (or any other sound along with this gurgling) that seems typical of the leak detection system.

There is the possibility that the car could have made this sound in the past but it was pretty obvious to me this time so I think I would have noticed it if it had occurred previously. One other note, I did fill the gas tank during the drive right before I parked it and heard this noise, but I drove probably 12 miles (including twice turning off the motor) between the gas fill-up and parking it in my garage.

Golf VI R :: APR Stage 1+ / Strange Noise Under Heavy Acceleration

I just went APR Stage 1+ (APR hpfp plus VWR intake) and am loving the noticeable power gain from Stage 1. But under hard acceleration I'm getting a strange noise (sounds like wheelspin or tire screech and sounds like it's coming from the front tires) when I disengage the clutch to shift at higher (5K+) rpms. It is not metallic sounding (it sounds like burning rubber) and lasts for a split second then goes away.

For those of you who've had tuned GTIs, it essentially sounds like what my Stage 1 GTI sounded like when too much torque was going to the front wheels and I spun my wheels before I got traction.

It doesn't happen as I re-engage the clutch and it doesn't happen any other time (quick but not WOT acceleration or normal driving). It also didn't happen under hard acceleration before I went from Stage 1 to Stage 1+. Furthermore, I'm not having any issues with difficulty shifting or engaging gears at any time. My R is 1 month old and has ~1K miles.

I've searched the clutch/transmission troubles thread, and other threads, but haven't come across other sounds/symptoms that seem similar.

At first I was thinking it was just a split second of wheelspin from too much torque as the AWD kicked in, but that doesn't seem to make sense (or does it?) since it only happens when I'm disengaging the clutch. Any thoughts before I start thinking the worst?

Golf IV R32 :: Strange Ticking Noise Coming From Engine Bay

About a two weeks ago, I had a CEL pop up. I brought it in to the stealership to get it scanned. I don't recall what the exact code was, but the description was something to the effect of "Cooling System Performance." I hadn't noticed that the engine temp was any different than it had ever been, so we kinda figured it was just a bad sensor. We popped the hood just to take a look at things, but he didn't really notice that anything was off. I thought the engine sounded a little difference. It wasn't idling rough, but there was a very subtle ticking noise. He didn't think anything of it. So he cleared the code, and sent me on my way.

The code came back a few days later, but disappeared about a week ago. Since then, however, my .:R has been feeling a little different. Like I'm losing torque. The ticking noise has become distinctly louder, although I can only hear it when I pop the hood. Last night, i was listening to it, and there are two separate noises, coming from two different locations. One is coming from the left side of the engine, most likely from one of the belts. The other is the one that worries me the most, as it's quite a bit louder. This ticking noise seems to be coming from the engine itself. The longer I let the car idle, the louder it gets.

One of my friends took a listen, and he suggested that it could be a blown piston ring. This would explain why I'm losing torque, but I haven't noticed any blue smoke coming from my exhaust.

Golf V R32 :: Strange Popping Noise While Driving On Highway

While driving at about 80mph today the rear of my R started popping. Felt like I had a flat tire. It stopped and started again. Once I got off the freeway it started to sound like I was dragging a muffler. I pulled over and everything looked fine. I drove home with a screeching/grinding type noise. You can also hear it when I put it in reverse. What is this? Is it ok to drive it to the dealership about 20 miles away?

Golf V R32 :: Turning From P To Reverse Is Rough / Strange Grinding Noise

So with the temps on the east coast being sub 17 degrees, I noticed my car acting up on cold start and all the way until the car is at operating temp.

1 -- Going from P to Reverse is rough! I allow the car to "break free" sort of speak, before I actually give it gas in reverse and once I give it gas the car bucks violently a couple times and seems to not want to actually reverse... Issue is gone after driving the car and letting it warm up.

2 -- Again right after cold start and until operating temp - Shifting in either D mode or Paddle mode going from 1st to 2nd creates a strange "grinding" noise (I will try to get a video clip of it). The sound is very similar to that of a MK 4 starter beginning to go bad, but not as loud. It only ever happened going into 2nd gear from 1st gear. Once the car was up to operating temp and driven around the sound did not occur. Even after starting the car up again after letting it sit for an hour or two it was okay.

Both things occur on cold start up with the car sitting for roughly 8-10 hours.

Golf IV / Jetta IV :: 2000 - Strange Whining Noise On Start Up

This noise happens usually on the first startup of the day, but it can happen at least 2 or 3 times a day randomly. I am not great with cars but if i had to guess it sounds like a belt is to tight or its a electrical problem but i have no clue. I attached a video of the noise for better in site. Apart from all the looks i get when i start my car up I'm just afraid my engine is gonna blow up on me randomly. The car is a 2000 vw golf automatic.

Golf - Volkswagen :: Engine Died After Making Strange Noise

After coming down a mountain pass my engine started making a weird sound and then died. I am told that it was because I was in too low a gear for the speed I was going (I was using the triptronic or whatever it is called to stay in a lower gear coming down the pass). I had clean and ample oil and no warning lights came on and there are 98,000 miles on it. Does this cause make sense? I have been reading in other discussions that many cars have crank shaft sensors, do VW cars have this? VW Golf 2005 TDI .....

Golf IV R32 :: Strange Clicking Noise Coming From Rear On Startup

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.

Golf IV R32 :: Strange Noise Coming From Front Driver Side?

So i have had my r now for a lil under 2 weeks, just noticed a strange noise, seems to be coming from the front drivers side, its a low whine/hum, almost like a pump or small motor is running and is very similar to when you use your wiper fluid. the noise is only present when the engine is cold and typically only does it two to three times while stopped. Just seeing if this is a normal thing, never heard anything like this on my previous vw.
