Golf IV / Jetta IV :: Howling Noise At 35 Mph And Above - Stops On Heavy Acceleration And Deceleration
Sep 29, 2014
02J-EGT 5spd. OEM axles.
Sounds like it's coming from the front. I noticed a few months ago my inner passenger CV boot was cracked, put motor mount spacers in which should have hopefully brought that axle up to okay standards. My initial reaction is to say the howling is from that CV joint however it's very odd it only happens after 35 and when I'm not heavy accelerating or deaccelerating- only when holding the car at a constant speed.
This also came after doing the TDI 5th. I notice it a little bit after passing 35mph in 3rd but really can hear it in 4th/5th when the engine revs drop. Am I right in thinking CV boot? Or transmission internal?

My VR6 is making a ticking sound when i accelerate, between 2800-3100, then it dies down a little and then gets loudest at about 3600-4000. The noise stops at exactly 4000rpms every time. Here is a sound clip of what the noise sounds like... you can hear it best in the last 15 seconds or so in the video. Maybe its the timing chains...

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?

While switching freeways yesterday and shifting down into 3rd before hitting the exit ramp I heard I a slight clunk, and then this continual noise began. I initially wasn't quite sure if it was my car or the sound of the of the large semi engine braking in front of me so I continued on to the freeway and was able to shift back up to 5th and get to speed.
However, I held back to around 60Mph because the noise started to worry me as I continued to hear it after passing the 18 wheeler semi. I got off at the next exit and noticed that the noise ONLY occurs when the car is decelerating. It happens in every gear as well as neutral; having the clutch in or out doesn't make a difference either.
*When accelerating in any gear, even the slightest bit, the noise disappears.
I've scavenged the forums to find a similar issue but to no avail.
I've uploaded a video that shows the issue occurring. The video is taken from the driver's side wheel, but the sound resonates throughout the front of the car, can't really pinpoint where though.

Lately I've been experiencing a howling noise upwards of 2000 rpm when accelerating under a certain throttle position... Basically makes a WOO type of sound coming from the drivers side of the car.. very noticeable and annoying. When I step on the gas harder it goes away, and if i just rev the car in neutral (no load) the noise will not happen! This makes it impossible to figure out where it's coming from with the hood open. Checked the IC hoses, air box and a bunch of vacuum lines and no luck...

Alright so car is a 13 R, bolt ons, c2 stage 2+. Drove the car yesterday morning all was good. Did an oil change and fixed my cts DV (the top nozzle had popped out, i glued around it as cts had suggested to hold it in place). At first the car was making an odd "weeee ooooo" sound on accel/decel. I went home, rechecked all couplers, vacuum hoses etc. then went for another drive, there is absolutely no boost. Car drives likes its naturally aspirated, no attempt to even go into boost just nothing. Ran vag com, no codes.

I just brought my6 Speed Automatic Transmission Phaeton V8 in, because under hard acceleration mostly between 3+4 or 5+6 for a short moment a howling noise with vibration into gear selector appears. I was able to demonstrated it to the Technician, but he said there is not much to do because no Fault code will show up and if he ask VW they will say he needs a reference vehicle to replicate it.

Last week i started to notice that my gti clicks on moderate acceleration, and again if I let off and using engine braking. I can only hear it with the windows down, and it seems to be coming from front of the car. My first thought is that the axle bolts might be loose, or I have a failing CV joint. I re-torqued to 70nm, and could not budge for the 90 degrees after that. So, they are tight - possibly too tight?
I've read a bunch of threads on relay clicks, etc., and do not think that's whats going on here. I'll double check tomorrow, and see if it's the 1000 rpm relay click. What this might be, or how to definitively know whether it is / is not the CV's? I'd be fairly surprised if the CV's are dying - I do not drive this car hard or beat on it at all, and generally keep it out of boost around town.
Details on car - '10, MT, about 30k. Koni coils at about 24.5" ftg, APR stg II, B&B TBE, all with about 15k on them.

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 ....

Ok - I admit, I don't have a good description of what's going on, but it's not normal. When I accelerate slowly, or go up a hill, I'm hearing a "rattling" sort of noise that did not used to be there. I have heard it also when slowly decelerating.
I need to crawl under and look, but my big concern is I'm about to go on a 2000 mile trip with a small horse trailer. Could this be a festering major engine, transmission, or otherwise problem?

When driving my 2003 Volvo XC70, it sounds as if I am driving on nobby mud tires. The sound (rrrrrrrrrrrr) gets faster and slower with the cars acceleration and deceleration. I know that the sound isn't caused by the tires because I am running on Micheline Harmony tires which are fairly quite. I am concerned that it may be a gear going bad.

It seems like every time I take a corner or make any sudden acceleration/deceleration that my driver seat seems to shift around--like it's not properly anchored in my car. It's hard to explain...Any aggressive driving around corners and such makes my seat make a slight popping sound, with some slight give. I never had this problem with my mkvi TDI I used to have (although I could never take corners as fast as my R). Also, my seats are already showing wearing on the bolsters (just over 2k miles). I know others have expressed issues with this. What is everyone else doing to remedy this?

My daughter has a 2010 Elantra 4-dr 74k
In the last few days, a new sound has appeared. It is hard to describe, sometimes squeaky, sometimes sound like a vacuum leak or air bypass.
It seems to steering related in conjunction with acceleration/deceleration. It only occurs when the wheel is being turned to the left, whether for a left turn or returning to center from a right turn. The noise seems to come from the center/center left of the firewall area.
It only does this while in motion, I couldn't replicate the issue with the car running but in Park.

Bought a Jetta GLI 2004.5 in January. 94K miles. No noises accelerating or while coasting (clutch or neutral). However, when I decelerate in 3rd and 4th gear w/ no foot on gas, there is a very apparent whirring sound from the front-end (maybe in the engine bay). But I don't hear it while decelerating in any other gears. What is the cause? I will try and capture sound later when I get home. Just wanted to see if this was a common fault.

Currently on my 1.8T I'm running a 3 inch catless downpipe into a stock res and muffler, it's great noise on acceleration but I've been told and found through research that if I want idle noise and a deeper tone I should take out the resonator, my question is what's it going to sound like on a catless downpipe with the stock muffler and no res also will there be enough back pressure to start okay and not loose any power, my last question is what's it going to be like on the highway when I'm at high Rpms for a long period is it annoying or does it sound nice ? What about cutting out the res with a 3 inch catless downpipe

I have noticed since day 1 of owning my v8, that there i a horrible sound that comes from the exhaust upon medium to heavy acceleration - a loud fluttering is the best way i can describe it. I took it to the dealer and one tech said something was definitely wrong, the other went and got a new reg off the showroom floor and demonstrated that it is common and normal. Although another new reg did the same thing, i am not convinced that this obnoxious sound is normal ...

Just bought my R a few months ago and love it so far. I've recently encountered a slight buzz or vibration. I'll get down to the nitty gritty and not bore you with long drawn out information. Basically under heavy acceleration the driver side vibrates/ buzzes down by the floorboard. Now this only happen under heavy acceleration. I even did a test in 1st gear. Heavy accellerate under 2k RPM's, 3k RPM's, 4k RPM's and the vibration happened under these heavy acceleration periods. It's almost like there was also a loss of power during this vibration/ buzz, which leads me to believe it might be the clutch.
I took off the prop shaft and drove in FWD for a few weeks. The vibration was still prominent. Took of both front driveshafts and inspected those and they seem perfect but THE VIBRATION IS STILL HERE. Could this be the clutch?

I have a 2002 Jetta GLS that I got recently, it has 136,XXX miles on it and has a whine sounds like coming from the transmission or differential that starts around 2000-2500 rpm and gets a bit quieter at 3000. Transmission shifts smoothly, fresh oil change on trans and differential with no difference. It does not whine if the car is parked and you rev the engine, only does it while driving. Transmission is automatic

Just this past weekend my wife got her 2010 Golf Highline with the 6-speed tiptronic transmission. Just a quick question about the gas pedal. when it is on "D" it really feels heavy and sluggish when going from full stop to acceleration. the pedal feels so hard and when you step on it feels like its not going at all. but as soon as it goes on 3rd everything seems ok. and then we tried putting it into "S" (sports) mode and everything was really good and quick. but when on this mode you need to be really hard on the gas pedal for it to run smooth. so i guess my question is...is it really like that when driving in the "D" mode??

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.

My problem(s) are as follows:
I recently got a 2001 VW Golf 1.8T from a buddy in the Marines. He delivered it to me at my home almost 4 hours away, as described, reportedly without any issues. I got all of the paperwork transferred so that my wife could have a solid daily driver, only to discover ...
1) The vehicle in question was apparently used by a car audio company local to him, who has done some serious screwing with the electrical system in order to incorporate (and then remove) their crap.
2) When shifting through the gears, and coming to 4th gear, you get a couple of seconds of initial acceleration, followed by deceleration and RPMs falling, which in turn leads to the speedo dropping.
3) The same thing happens in 5th gear.
4) The only option is to downshift to a lower gear, which she did, and was apparently cruising along at 60 mph in 2nd gear, as 3rd gear was behaving the same way as 4th/5th upon downshifting. I'm not a mechanic by any means, but I'm pretty sure this is a BAD thing .
