Golf IV R32 :: Clunk On Deceleration?


May 3, 2010

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?

Tiguan :: Front End Clunk / Knock / Loud Pop On Deceleration

The car: 2012 Tiguan SE 4mo (auto)

The noise: there is a loud pop/cluck/knock from the front drivers side footwell, can sometimes be felt in the pedals

When it occurs: Most frequently it occurs on deceleration. Letting off the gas, there is a slight delay then the noise. It doesn't happen every time. The intensity of it is very sporadic and unpredictable. In stop and go traffic, it is typically the worst, gently accelerate, let off the gas, loud clunk. During other normal driving, accelerate up to normal (55mph) speed, let off gas, quieter clunk, intermittent. Infrequently it makes the noise when I shift into reverse. I can also hear it faintly when i start the car sometimes.

There seems to be very little correlation to vehicle speed and the noise. It is typically louder at low.

Golf VI R :: Odd Sound On Acceleration / Deceleration

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.

Golf IV R32 :: Exhaust Firecracker Sound On Deceleration

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.

Golf IV / Jetta IV :: Whirring Sound Upon Deceleration

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.

Golf/GTI VI :: Clicking On Acceleration / Deceleration At Low Speeds

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.

Golf IV R32 :: Burst Vacuum Pipe And CEL After Rapid Deceleration?

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.

Golf IV R32 :: Whirring On Tight Left Turns Under Deceleration

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.

Golf VI R :: Popping And Gurgle Sounds During Shifts And Deceleration

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?

Golf IV R32 :: Whining Coming From Rear Differential Under Deceleration

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.

Golf IV R32 :: Rear Diff Started To Whine On Deceleration

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.

Golf/GTI VII :: Whistle Sound Mostly Upon Deceleration When Engine Was Cold?

[URL] ....

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?

Golf VI R :: 2013 With 30K Miles - Whirring / Rubbing Sound During Deceleration

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.

Golf IV / Jetta IV :: Ticking / Clicking And Rubbing Noise During Deceleration Only

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.

Golf/GTI VII :: Buzzing Sound Around 2300 - 3000 Rpms Mostly During Deceleration

Manual... I hear this buzzing sound, mostly during deceleration, on 2nd, 3rd or 4th gears between 2300-3000rpms, very annoying on 2nd and 3rd gears, but can still somewhat noticeable on 4th gear. Can also hear it on acceleration, sometimes on 2nd and 3rd gear, silent on 4th gear.

I've turned off soundaktor thru VCDS, but still hearing this sound so I was thinking that the hockey puck is still spinning, albeit not as annoying as when it's 100%. So I tried to disconnect it, still hearing that buzzing sound. I even removed all stuff from my car and it's still buzzing. Really annoying, specially if you just want to hear the sound of the engine braking on deceleration.

Golf IV R32 :: Rapid Deceleration After Taking Foot Off The Gas - Getting Code P3801

Today I noticed that it feels like my R decelerates rather quickly as soon as I take my foot off the gas. In my old GTI, it seemed that it would glide in whatever gear I was in for a while. In this, however, It seems to slow down VERY quickly if I am not pressing in the accelerator.

Am I just crazy, or could this be an actual issue? My only thoughts are that the emergency brake cable is too tight and the brake is stuck on a little bit? Any thoughts?

I do have a CEL on from code P3801, which I read is most likely the ECT sensor. I know this may cause a loss of gas mileage, but could this be the culprit of this (almost) issue?

Golf/GTI VII :: 2015 - Odd Engine Deceleration - Getting Error This Isn't A Good Time To Put Car In Reverse

Yesterday I was driving about 120 km/h on the highway, my 2015 GTI (DSG) suddenly decelerated to about 110 km/h -- the sensation was that the engine downshifted on its own.

The transmission was in Drive, and I wasn't in sport / automatic mode. An error message appeared on the dash display telling me, 'this isn't a good time to put your car in reverse' -- or something to that effect (I don't remember the exact wording as by the time I pulled over to the side of the road the message was gone, but the yellow warning notification symbol was still up.

I turned off the car, let it sit for a minute or two, and then restarted it. The yellow warning symbol was no longer lit up, so after letting the car idle of a minute, I pulled back onto the highway and proceeded to my destination without further incident.

The car is at the dealer this morning for diagnostics.... One thing to note: It's been very cold here in Ottawa, Ontario, Canada these last couple of days (-25 C) and yesterday I didn't 'warm up' the car as much as I normally would as I was running late for an appointment. Wondering if that might have had an effect... It's the only thing I can think of that's a variable.

Golf IV / Jetta IV :: Howling Noise At 35 Mph And Above - Stops On Heavy Acceleration And Deceleration

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?

Golf VI R :: Driver Seat Seems To Shift Around When Make Any Sudden Acceleration / Deceleration

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?

Golf IV / Jetta IV :: 2001 - 4th And 5th Gear Won't Working Properly / Deceleration And RMPs Drops

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 .

Golf VI R :: Clunk When Going In Reverse And Then Braking

I've been noticing when going in reverse and then braking, when then going forward and braking there is a clunk which seems to come from the front brakes. Is this normal? Shifting of the pads in the caliper?
