Golf VI R :: Popping And Gurgle Sounds During Shifts And Deceleration
Aug 13, 2014
Exhaust systems/setups that make the MOST popping and gurgle sounds DURING shifts and deceleration. I know decel popping happens when there is less air in the combustion chamber and any unburnt fuel in there will burn at a much slower rate, slow enough that some of it is still burning as the exhaust valve opens causing the pop. So, with that said...which system out of the box would most closely fit the bill without getting too technical?

Getting backfire or popping noise after deceleration with our cars. It didn't do it before with oem exhaust, just wondering if we're going to get a little bit from my new joe z exhaust, or do I have a leak somewhere with my installation. Or do I just need it break in a little more. How do I check for leaks , Do I just need to ramp the car and check all the flanges for where the exhausts bolts up and check for alignment issues.

This is the 3rd time this has happened to me in the past week. As I am cruising I start to hear my exhaust gurgle a bit then the EPC light comes on and the tach starts bouncing around although the revs of the motor don't seem to match it. Then the car dies on me. If I give the car like 5 minutes I can start it up again otherwise it just cranks and cranks and will not fire. But today it did it again after I was able to start the car. I did some research but no one really had the same issue I have. One person said the EPC comes on if a sensor is bad/going bad. I was thinking it could be the engine speed sensor since the tach was bouncing around, but not sure. I don't have a VAG but can probably get a local to scan the car for me.

I have a 2003 Explorer EB that on deceleration of all speeds, the drivers side rear axle is popping or clicking. Could this be a CV joint? It does not happen on acceleration.

Turned the car off and I could hear what sounds like a bubbling or gurgle of some sort coming through the center console vents, no dash board lights or anything leaking, after being off for 15 min it stopped, I will notify my dealer, what this may be ?

The car is at rest, engine on, when I turn the wheel (either sides), there is this popping sounds, coming out from the front suspension. It almost sounds like the Titanic moments before it fell apart... It also happens when I drive slow, like parking or backing out...etc. Doesn't happen at >10mph.
So I had my friend turned the wheel and I inspect it. I can feel the spring or something popping on the strut mount of the front wheels. SEE PICTURE.
I also uploaded a video with sound. I have sufficient tools to remove the struts and springs.

Got a 2010 Corolla S (105k mi) . I have a noise in the front end. I hear it occasionally when I'm braking, and other times when I'm turning left. Just started tonight. I really need to get this fixed before I go out of town in a few weeks. Don't want to leave my wife with am unsafe car.
Anyway the sound varies, sometimes it's more noticeable then others. The first time I heard it I thought I ran over something metal. It has a sound as if someone pulled on a bar and let go and it sprung into place.
The sound is in this short video, don't worry about seeing anything, but you can hear it at the end.

I have a 1999 f350 crew cab. There is a gray box with some wiring running to it and when the door is open I here a little cracking and popping sounds. It is between the steering wheel Column and the ashtray under the dash. I can hold it and feel it clicking and popping, What that is called, or how to get it out to replace it?

ive read through most of the "clunk" threads none fit what im experiencing. so anyway, i just got the car back from getting the coil packs replaced under recall and im driving on the highway cruising at a steady 70mph. every time i take my foot off the throttle from a steady speed or accelerating i get this clunk and quick vibration in the front end, i can feel it through the steering wheel. thought it was the adapters so checked them, theyre all torqued properly. i can feel the clunk through the steering wheel, and its not the normal clunk when the awd disengages. it only happens at highway speeds when i let off throttle. could it be the dogbone or other engine mounts maybe?

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.

Second gear, I am going 40mph and I let off the throttle and start engine breaking. My exhaust burbles and crackle a LOT. Now, I love the sound. But just want to make sure it is normal. I just took my rear seats out, so I am not sure if it is louder / there because of that, or its just a coincidence.
I read a thread a while back where a fellas intake changeover failed and it started doing that really loud as well.

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.

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.

The other day I decelerated rapidly. I didn't slam on the brakes, but I went from maybe 45mph to 0 in maybe 40 feet or so. When the car stopped, the CEL came on. No apparent issues at the time so I drove it the last few miles home. I checked under the hood with the engine running and heard a whistling noise which I tracked to the plastic pipe connecting the intake manifold to the brake booster. I didn't take a picture of it, but it is the one that has a silver heat wrap on part of it where it passes close to the throttle body. I grabbed a random pic online that kinda shows it.

I believe this pipe feeds air from the intake manifold to charge the brake booster? If this was the case, I thought possible by hitting the brakes harder than usual the back pressure at the check valve was enough to burst the plastic pipe, which may have been heated, stressed already? Then the vacuum leak caused the CEL?
What is the actual purpose of that pipe. The car is well maintained with recent service and just over 30K miles.

It's not entirely repeatable but only happens on tight left turns under deceleration such as a u-turn or turning left into a parking spot. The noise is a continuous whirring like a bit of plastic is rubbing the front passenger tire tread and continues for a moment even as I straighten the wheel out. I'm going to take the wheel off tomorrow to change my brake fluid and will take a closer look then. I'm on stock suspension and wheels.

Have some 'whine' coming from the rear differential under deceleration. In my case it just started occurring last night and seems to be audible over 55MPH and while in 5th or 6th gear after I let up off the throttle as to engine brake.
It seems like the answer or solution pertains to the input shaft pinion retention nut eventually backing off, as well as oil starvation to the unit, but has this actually been confirmed? My rear diff was replaced over 4 years ago under warranty after it failed and enduring 2 wheel drive for a bit.

My rear diff had recently started to whine on decel, what I am looking to find out is, would replacing the stock rear diff itself with a peloquin unit be enough of a fix, or should the whole rear housing be replaced as well? I don't want to buy a peloquin rear diff and install it and still have issues because of the pinion shaft being the culprit or something else.

I have a whistle sound mostly upon decel when the engine was cold. I have the APR down pipe installed. Today it's doing it all the time even when warm. I took the car to the dealer and they said it was prolly an exhaust leak. I took the car to my friends shop and we put the car up on the lift and listened from underneath. It sounded like the turbo was echoing in the down pipe. Sometimes when it's cold it can be very loud. So my question is if this is normal with the APR down pipe or with this turbo or is this a sign that I have a turbo failure coming?

Started getting a whirring / rubbing sound during deceleration and took it into dealer for diagnostics. They said driveshaft needs replacement. Fortunately they are covering under warranty but it's got me concerned about longevity.
I've got an APR Stage 1 ECU upgrade but otherwise stock. Not a track car and i'm not moonlighting at the drag strip dropping the clutch at 5000 RPMs to try and make into the 11's so am baffled by the issue.

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.
