I have a new sound. I recently swapped my coolant and thermostat. After that a slight whistle has developed. It seems like it is RPM dependent, it hasnt gotten any worse after a solid 400 miles of driving, but it also hasn't gotten any worse. It sounds like if someone has slightly blowing into a whistle, but not all the way. What it could be?
View 24 RepliesI recently installed an odyssey pc925 in the trunk of the R and now I'm hearing an RPM dependent whine. I actually happen to have the same head unit (Pioneer AVIC Z1) but I don't have any RCA cables hooked up, so I don't know what could be causing the whine.
View 19 RepliesMy 05 V8 has developed a slight whistle when the air conditioning is turned on and the fan speed is high. This only seems to happen when the system is taking in outside air. If it is recirculate mode, the whistle goes away. It also goes away if you manually turn the fan speed down. My assumption is that something may be caught in the intake.
View 4 RepliesI have a brand new 2010 Tiguan that has a slight whistle coming from the engine on occasion. It is constant and not engine speed dependent.
View 5 RepliesEarlier 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?
I noticed a slight whistle last year coming from my front left hub. I pulled the hub and greased the gears as best I could and it sort of went away. Now this year it is a little louder. It only happens when the hub is locked. Is starts around 20mph and goes away at 40. Is the bearing in the hub shot or is this normal. 4x4 works fine and there is no visible excess wear on the gears. The truck has 93k.

I have recently developed a slight whistle/squeal when boosting and when letting off on the pedal. I initially thought I had a CAC boot starting to split out, but since it's making the noise when I let off as well I doubt that the problem.
It isn't constant, and only does it for a second or two when it happens. It's not extremely loud, just loud enough to make you wonder what the heck it is...
I have a '13 6.2 with 11k on it and it's started making a weird noise since the temp has turned cold. At first I noticed a slight whistle at certain rpm's but the temps were around 0 so I didn't think too much of it since stuff gets noisy the colder it gets. Today the temps were in the upper teens and I'm noticing a new sound. From around 1000-1500rpm I'm getting a whining sound that is noticeable in the cab. It's coming form the engine since it does it while sitting and I can make the sound appear by getting the engine at the correct speed. It's louder when the engine is cold but I can still notice it a bit after the engine is at operating temps. Below 1000 and above 1500 rpm there is no noise. I never really noticed it before, but since I heard the slight whining last week I've been listening more and I know that's when you start hearing noises that you normally wouldn't pay attention to.
View 1 RepliesYesterday, I noticed a rattling sound coming from the entire car a 2002 subaru outback 2.5l 4 cylander (it seems a bit louder on the passenger side but it literally can be heard throughout the car). I was on the expressway and got off and stopped at a red light when the check engine light came on and started to flash and the rpm's dropped rapidly and the needle began to bounce up and down. I pulled into a gas station to check it out more and popped the hood to find that when the car is rattling it is also shaking and rocking the engine of the car from side to side slightly.
When I'm idling the rpm's drop and the car feels like it is going to stall out. Then, as I accelerate, the rpm's barely go above 2000 and jump up quickly between 3000 & 4000. It sounds like a metal on metal rattle with a very slight high pitched whistle and you can hear a fan kick on and the engine try to keep the rpm's up every couple of seconds when the car is stopped. I had the timing belts replaced 2 years ago and it sounds very similar to how it did when they needed to be changed, however, the engine never felt like it was going to stall until yesterday.
When idling the noise gets louder and when accelerating it can still be heard but barely. Also, the rattling has caused the entire car to vibrate all of the time. I noticed yesterday that the oil was low and topped it off, but I don't think that would cause such a hige issue so quickly. When I go uphill, i have a good amount of power but every 30 second or so the car shifts and the rpm's jump lurching the car forward because of the surge of power. Also, when I hit the brakes, my rpm's jump slightly to about halfway above the 1 but the engine does not accelerate.
When i first got my MKV R32 it was such a great handling car. I was able to got very fast on curvy roads with not even a slight bit of skid or squeal. Now its developed this rattling and squeaking sound. I feel the bumps in the road more, i notice more body roll, and alot of vibration in the steering wheel, and what pisses me off the most is i hear more squealing on turns that i used to be able to take faster with no squeal. For example i used to b able to take this turn at around 75mph no peel, now i started peeling out at like 63. (my tires have alot of tread) when i got the car it had around 17,000 mi on it now it has 31,000 mi.
View 17 RepliesMy 2011 Golf with the 2.5 has developed a rapid chirping sound at 55-60 mph, that varies in rapidity as I decelerate from 60 mph. Doesn't do it at lower or higher speeds. It isn't terribly loud, but noticeable. Only have a little over 24,000 miles on it.
View 5 RepliesMy driver's seat has developed a popping sound when I move around, especially moving forward and back. It seems to be coming from the cushion in base of the seat or maybe down in the lower part of the seat back. I remember a thread a while back about this problem but I forgot what the diagnosis and solution was. I did a search but nothing came up, maybe I just used the wrong key words, I don't know.
View 24 RepliesI'm a new Mk4 R32 owner in the Portland area and my driver's front suspension developed a nasty squeak on the long drive home after buying the car. When you hit a pothole or any sort of bump it makes a nasty "clink" sound under compression/rebound. It's only on the driver's side front, and it seems to be a bushing/bearing or upper mount in the car when I got it up on Matrix Integrated's lift.
Also - the driver's front spring is squeaking since the powder coating flaked off after all the miles.
Thinking of buying a cheap set of coil overs to remedy this and refresh some of the more worn suspension items. Car drives just fine too.
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.
View 19 RepliesI've been all over the place trying to get this pulley sounding noise figured out. the noise is definitely not the pulley, but is coming from that side, and from underneath the engined towards the back. this noise only occurs when car has been driven at least 30 minutes to an hour from first start of the day, but then continues the rest of the day. the noise also only occurs when I am coming to a stop or just rolling at a low idle, and then only lasts for about 30 seconds and goes always until i give it so gas and the noise comes back.
I know its sounds a lot like PVC, but i have had all that checked and actually pvc replaced. Took it to another VW dealer, and they charged me for diagnostics, and came up with it the noise was coming from somewhere in the clutch, and want to replace the whole clutch, that was just replaced by them 20,000 miles ago. You would think if was coming from the clutch it would make the noise at all times. Do you think it could be the clutch in any way?
Installed the GFB DV+ noticed a bit of a whistle at idle after installation? You can't hear it inside the car, but if you have it idling and step out, you'll notice it if you have it. It's almost like a vacuum cleaner in the distance, it's not very loud.
View 4 RepliesSo I have an odd whistle noise, when I give it a little gas it makes a faint whistle noise. Only happens on acceleration with a little gas, I don't think it's the turbo.
2016 GTI SE DSG - no mods...
Started a few days ago, There is a faint whistle noise when I am open throttle around 2500rpms. It lasts for about a second and does not occur at any other time. It does not occur under gradual acceleration, or when the car is parked/in neutral and just revving. I tried searching the forums *a little* bit, but my keywords just may have not been right.
My first inkling is that it may be related to flapper, since the rpms seem right and sounds vacuum related to me. But, the unit is completely disconnected (have borla cat-back) and the hose is ziptied, so is this possible? I will try to get a video of the noise later today.
So when I shift from 2nd to 3rd I hear, for lack of a better word, a 'whistle' type noise while shifting. It sounds like its coming from inside the car under the shifter.
View 1 RepliesMy 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.

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?
