Golf/GTI VII :: Whistle Sound Mostly Upon Deceleration When Engine Was Cold?
Jul 23, 2015
[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?

My wife and I just bought a pre-owned 08 Jeep Grand Cherokee with about 60,000 miles that just started to make a whistle sound on initial acceleration and deceleration when the engine is warm and the transmission is in gear and moving. The sound does not happen with a cold engine, when the transmission is in park, or neutral. A local mechanic checked it for vacuum leaks and didn't find any. He thought it may be a dirty throttle body, so I cleaned that out really well, but the whistle didn't go away (it did make the jeep run a lot smoother!). It's difficult to pinpoint the noise since it only happens when the vehicle is actually moving.

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.

My car came with the Evoms CAI stage 1 with the sock. When its drawing in air I'm getting this annoying whistle sound. Ive had other intakes on my other R and this is just plain annoying.

For three years now my 2001 Jeep Grand Cherokee Laredo will whistle. Usually when the engine is cold. When the vehicle is idling in the driveway or at stoplights, whenever I take my foot off the accelerator it will whistle too. The only time it won't whistle is when the gas pedal is being pressed. I've had it to a number of different shops to be serviced but once the car is inside or the engine is warmed it will never whistle for the mechanic looking at the vehicle. I've been told that it could be related to the IAC motor.

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.

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.

My new to me Golf makes a strange "whistle" sound around 2000+ RPM. In any gear only when accelerating. My car does not have a turbo so its not that, the sound is coming from the motor it self. Very strange.
I dont think it comes from the tranny or clutch.
Car has 95K miles on it, t-belt and water pump done at 68k (but in 2008!, inspected it and the belt looks fine, no cracks or fraying or anything) This whistle sound is so strange. My wife says it sound like a whistle then it changes to a slight vibration sound.

My brother and I noticed my engine making this noise today, I was under the hood and he was giving the engine gas with the car in neutral.

Sounds like air pressure being released, sort of a quick whistle or squeal just as he pushes the gas pedal, coming from under the hood somewhere.

So i have been hearing a whistle under acceleration for some time. Normally comes at 1/2 to full throttle. I also have had check engine light for a bad o2 sensor for about the same amount of time(2months). Fast forward to last week. finally replaced sensor. Check engine is gone. Open her up a little on and on ramp, Whistle is still there and the CEL comes back. Have it scanned, and it come back load calculation cross check 17551. I need an sticker so i rest the ecu (no light) and drove it like a grandma 50miles to get the sticker. No CEL. Get sticker. Just to make sure i wasn't crazy i gave her some gas on the way out of the inspection lot, and there is the CEL.
In conclusion, Between the whistle, CEL, and the fact that i drove it 50 miles with out the CEL coming back under very light throttle, and i just replaced the MAF with a new Bosch 2 months ago, i am pretty sure it is some kind of vac leak.
I have a new TB gasket in the mail, but my question is, Is there other places where such a vac leak is common in these cars? Other info on car.
UM tune
evoms intake
HPA downpipes (whistle started after these where installed)
Flapper
no res
74k on the clock

It's a 96 850 Naturally Aspirated. There is a whistle sound (usually about one second in duration) when I let off the throttle.
Based on what I've been able to find out so far it is most likely at Vacuum line or a gasket somewhere in the intake line. The more common source of this is the Throttle body gasket but that doesn't seem to be the case.
I think the sound is originating on the left portion of the engine, somewhere between the oil cap and the timing cover.
Any good ways to test the vacuum lines or gaskets?

I usually get this sound when the engine is completely cold. I get a weird pulsating sound that's very loud, after the engine warms up a bit. It goes away completely.

Earlier today on a easy drive (not pushing it) I noticed a slight "whistle-sound" that I haven't noticed before. About then it became VERY sluggish and the Engine Management Light started to flash.
As soon as I could I pulled over and connected my AL619 and it says "to low turbo/supercharger flow".
I didn't notice any smoke or smell, just a serious lack of power (i was doing 30km/h at the top of the hill).
Just tried to locate the leak, but I cant feel it or see it. I guess one would need one of those "smoke generators" to see where the pressure goes out.
So, do I have a broken turbo, or just a blown turbo pipe/tube?

This might just be car engine in general regardless of make or model, but upon a cold start, my GTI engine whines or buzzes for approximately 1 second before it stops. I had a 2009 Toyota Corolla that also did this, but I had it fixed with a TSB due to the oil not reaching the VVT-I gears or something in time. It's not the same noise in my GTI, but I was wondering about same sound almost every time upon a cold start?

To get straight to the point: I have a 2013 GTI that has recently started making a screeching noise on cold starts and during engine acceleration (not necessarily heavy load, but actual engine speed acceleration).
I recorded a video of it this morning and it is very easy to discern the sound. The car is APR stage 1 tuned and has a south bend clutch but I don't think either of those are related to the sound. The water pump has been replaced from the service bulletin, the auxiliary belt tensioner has been replaced because it started to make a noise (this noise is completely different). Otherwise the car has never given me an issue, it has been maintained exactly per the OEM repair schedule other then oil changes every 5k miles vs. 10k. I use mobil 1 0W-40 oil.

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.

Yup, my truck randomly whistles while driving in cold temperatures. Its not life threatening or damaging to the truck, its been doing it for a few months not that its been getting below freezing. Its just REALLY annoying. I can even hear it over my radio at times, so its pretty dang loud outside of the truck. The noise originates from somewhere under the hood in the engine compartment.
Won't do it at lower speeds, usually on the freeway. Motors at about 2k rpm and im going roughly 65-70. Change the rpm when it whistles and it goes away. happens randomly from 50mph to 70mph engine speed from 1.8k to 2.5k rpm. I've tried to find it but can't find a darn thing since it won't make the noise while sitting in my driveway. What it might be?
