I ran over a parking stone last summer, ripped the plastic undercarriage a little, but alignment was fine, wasn't that bad, etc. I took the car to the shop last week for a strange whistle/squeal on acceleration and letting off the gas (PCV valve under recall) and they stated that my radiator support was broken, and the radiator was hanging there to the tune of 750 bucks.

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...
The title pretty much explains it. Coming home today started hearing a squeal/whistle while at highway speed - almost sounds like the brake wear indicator tabs that GM is so fond of. Thought it might be the brakes, but it didn't stop with brake application and continued after coming to a full stop. Also, surging at idle, which seems to be reduced when the A/C compressor is on. The squeal happens both with and without A/C.
View 1 RepliesCurrently having a possible 'issue' with my 2012 Passat 3.6. Every time I perform a hard acceleration, or any time the RPM's exceed 4,400, I can hear a whistle that is rpm-based coming from the engine bay. It is quite notable from outside as well, and ONLY occurs when the A/C is ON. Is this something I should be concerned about? I never hear it when hard accelerating without the A/C on. It is a high pitch whistle that increases in pitch the higher RPM's that are reached. Sounds almost exactly like a turbo, but as soon as I change gears in the acceleration, the pitch instantly drops back down but still matching (pitch-wise) rpms in the next gear and continues again.
It's loud enough to hear it in the cabin, but not over, say, 6 of volume on the radio.
When I take my foot off the brake, there is a squeal or whistle. It's sporadic and sometimes loud and long, other time low and short. It doesn't seem to happen when the mechanic is driving. And they can't determine cause.
View 1 RepliesMy 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.
My truck started making this whistling sound a few thousand miles ago. Its a high pitched squeal coming from somewhere under the hood. There doesn't seem to be any pattern or certain time when it does it. Ive read on here about an alternator problem on these trucks. Or could it be my S&B intake?
View 13 RepliesMy GTI has started to bog out, i guess is the best way to describe... As I am trying to accelerate on the highway my RPMs rev up to 5000 till I get any response to amount of gas I am giving. It will dramatically drop to 3000 without letting off the gas. then gradually will accelerate, untypical to way it use to perform. She respond this way cold or hot.

What could this be?
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

I have a 02 2.0 Jetta with 179k
Have that pesky "whistle under acceleration" when past 1/4 throttle issue. I have been going over the entire engine, checking and cleaning.
-----On the intake tube where the 1 inch case vent and half inch tube meet there is a Flapper/Flow check with a electrical connector directly on top.
Question being, is this a flow sensor? The flapper is distorted and does not function properly.. is this an issue?
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.
View 8 Replies2007 F-350 4X4 King Ranch... I have the 6.0 diesel. I am on the road to Houston, Tilden and San Antonio TX, and I am noticing a whistle on acceleration. I can change the tone by how hard I push down on the accelerator. I thought it was a radio issue and turned the radio off and got no change. Turned the a/c off, no change. Down hill or coasting, nothing.
View 3 RepliesPretty nice condition 2003 1.8t Passat 5 speed yesterday with 45k miles. nice price, mint interior, only a few minor blemishes on the bumpers.
Anyways, I was noticing that the gas pedal needs to be pushed in about half half before the car wants to move. I do not believe it was the clutch going bad as the engine wasn't revving when i was letting the clutch out, it just didn't seem to move until the gas pedal was half way down. again, no clutch slippage, engine was not revving.
My wife drives a 2004 passat 4 motion 1.8 T that for a couple of days has been acting up. By acting up I mean it will turn over but won't start. When this happens and after letting the key out of the start position, the epc and cel light will stay on. After letting it sit for a while it will start.
View 2 RepliesExperiencing a squeal under hard acceleration at 3000 rpm with roughly 20lbs of boost, not present before and not present after 3000 rpm. light acceleration to 3000 rpm does not create sound, as well as turning 20lbs at a lower rpm (higher gear with throttle input). Truck has an EGR delete, EGR delete up pipe. EGR valve is still in place and plugged in. Truck did come with a banks six gun, so does not have EGR delete tune, however no trouble codes are present. What to check?
View 9 RepliesFor a month or two now my truck has been making a squeal and the turbo has been sticking after hard acceleration. The sticking was a woebegone unison ring and I was hoping the squeal would be resolved when I cleaned the turbo but it didn't, in fact, it got worse.
It used to be occasionally and go away after warming up, but now it's more constant than not. It goes away when the VGT does its idle cycle and once you get up to speed.
Here's the sound - YouTube.....
When accelerating I hear a whistle noise from the engine after 4k rpm. The whistle noise becomes higher as the rpm increases.

I was noticing today when i started my car that it was making a whistle noise. So naturally i popped the hood to find the source of the noise. It is from this hose that connects to my header it has this crack in it and it is sucking air in.

View 2 RepliesFor a week now, my car whistle pretty loudly (I can hear it windows closed) when accelerating. After reading about 2.0t problems, I thought it was either a bad DV or PCV. I tried to diagnose if my problem was related to a bad pcv. So I disconnect the tube going from the intake to the pcv and plug the hole on the intake. Then I went for a ride and it whistle like before...so does this test confirm that my pcv isn't my problem?
As of now, I never saw traces of oil around the oil filler cap. When the engine is running, as soon as I press on the accelerator(even lightly), the whistle begin. As soon as I remove my foot, it whistle for a second then it stop. At a stop, if I press on the accelerator, the whistle will begin at only 5500 rpm and up.
No CEL so far related to lost of boost(I had a cel last week and they change fuel sensors and regulator). Also, the car pull pretty constantly but seem less powerful than before.
