So I posted here a while ago with a question regarding my Golf and a strange whining noise it made on cold starts. I took it in to the dealer to find out what was going on (warranty) and they said it was the secondary air pump making the noise and that it was normal.
View 9 RepliesI've run into a very strange whining noise in the mornings on my 2010 Corolla S.
I've done some diagnosis and the issue only occurs when it gets chilly out (below about 50 degrees). When you go out to the car in the AM with things dead cold and turn the key into the run position before you start it the noise starts up right under the dash on what sounds like the passenger side. I've tried the fan on and off and it doesn't seem to affect it. It does seem to be lasting longer and it really sounds like a bad bearing in a small motor. As the car warms up the noise disappears and doesn't reappear unless it cools down all the way, which usually means it has to sit overnight.
It doesn't seem to affect how the car runs so I'm guessing it's not a primary system, likely something with climate control or AC?
This noise happens usually on the first startup of the day, but it can happen at least 2 or 3 times a day randomly. I am not great with cars but if i had to guess it sounds like a belt is to tight or its a electrical problem but i have no clue. I attached a video of the noise for better in site. Apart from all the looks i get when i start my car up I'm just afraid my engine is gonna blow up on me randomly. The car is a 2000 vw golf automatic.
View 7 RepliesAfter coming down a mountain pass my engine started making a weird sound and then died. I am told that it was because I was in too low a gear for the speed I was going (I was using the triptronic or whatever it is called to stay in a lower gear coming down the pass). I had clean and ample oil and no warning lights came on and there are 98,000 miles on it. Does this cause make sense? I have been reading in other discussions that many cars have crank shaft sensors, do VW cars have this? VW Golf 2005 TDI .....
View 15 RepliesIn cold weather, I hear a periodic whining sound from inside the car, any speed, disappearing after about 5-10 minutes when the car is completely warm. It seems to come from the driver's side dash or foot well. It is getting worse with time. Car is very new, only 2500 miles with no other problems. It is not the heater. It is not from the engine bay...I think. Very weird. Only happens when the weather is cold and disappears when the car is warm.
View 3 RepliesSo my rpm bounces at idle and there is a strange whining sound which seems to be in unison with the peak of the rpm bounce.. and it all stops when the heat or a/c is off.
View 13 RepliesMy 2001 VW New Beetle has started making a loud, whining noise coming from outside the car along w/ some buzzing whenever I am driving. I find that I have to change gears about 10 miles sooner than I should in order to stop the noise. But now it's happening in 5th gear occasionally too, and of course I can't go to a higher gear to make it shut up. What could this mean?
View 3 RepliesSo after I start my car in the morning (it's garaged in AZ, probably 60 degrees) about 1 minute after leaving the house there is a real odd noise in the back passenger side of the car. It almost sounds like it's coming from the fuel door area.

Happens for about 45 seconds, and then it's gone and doesn't happen again. It's not correlated to the engine speed or whether the car is moving or not.
I drive a 2005 Camry SE. In the mornings, when I start it up for the first time, my engine almost...growls. That's the only word I can think of. Not even growl. But instead of purring like a kitten, it purrs like a tiger . And it's only when I first back it out and then take off. Once it's good and warmed up, it drives and sounds perfectly. Shifts beautifully.
And this morning, I let it warm up for awhile and it didn't make any noise when I took off.
I talked to my coworker about it and she said she had a similar issue with her 2004 Saturn Vue and it was something about a manifold, but couldn't remember what it was called. And she said her mechanic was able to fix it, but only temporarily and then told her it would cost her big bucks to fix it permanently.
I have a 1999 BMW 3 series, 112K, 5 speed, immaculate condition, only full synthetic oil used. After a cold start - even today at 55 degrees - I get a strange noise from the engine compartment which gets louder according to RPMs. The BMW dealer replaced the oil separator for the motor ventilator and some of the respective hoses and valves associated with it. They also checked the oil pressure when the motor was hot and cold and advised it's fine; however, the noise is still there. (A different BMW dealer service advisor said, just after hearing it, it was an oil pump issue.)
On an unrelated note, when the motor is warm and I'm in stop and go traffic, the idle speed will sometimes go up and down (500 RPM - 900 RPM), and when it reaches 500 or so RPM, it dies. The car always starts back-up right away. Spark plugs are new and I used OEM BMW spark plugs. My thoughts are the idle air control valve.
Otherwise, the car is great; yesterday I took it on a 250 mile RT highway trip without any problems.
I've got a stock '15 F250 6.7 w/ the Diesel Site FF67 fuel/water separator and a 50gal Titan Tank. I installed the filter + tank at the same time around 2 months ago; A few weeks ago, I started noticing an odd buzzing/whirring/gurgling noise (both while the truck was running, and while the fuel pump spins up right after turning the key on). I made a quick video of it this morning:
Ford F250 6.7 w/ Diesel site filter DFCM buzzing/whining - YouTube
I thought maybe it was a filter related problem (I got some little black plastic bits in the filter after installing the Titan Tank, despite my best efforts to clean it out thoroughly before installing) - so earlier this week, I replaced both stock fuel filters, and both filters in the DS filter. Didn't seem to affect the noise from the DFCM at all.
I guess my question is - does it sound like this is sucking in air? I've never found any leaking fuel (even after a 3000mi drive from TX to VA and back), and the truck has never complained about low fuel pressure as I've read that some others have run into. But I don't remember the DFCM/low pressure pump being this loud before I installed the new parts.
I spoke to the folks at DieselSite a day or two ago (those guys are great), and they mentioned that sometimes the Ford quick-release fittings work themselves a little loose from the fuel hose during the filter install, and that putting a hose-clamp around the hose+quick release fitting may solve this; I ordered from clamps from McMaster Carr that arrived today, so I may give that a try tomorrow just to see if it changes anything.
I am driving a 2002 VW Golf GL and my temperature light is flashing on my dashboard.
It was on for about 2 weeks before the temp gauge actually started rising.I then took it to "my" mechanic and they said it was a faulty temp gauge that wasn't opening and closing correctly. Fine. Done and Done. Sensor and gauge a few hundred bucks. Done. Right? Wrong!
Not more than 2 weeks later the light came on again with no temp rising.Just yesterday I was driving and the temp started rising. I quickly flipped on the heat to alleviate some of the hot air in the engine and cold air blew out of the vents. I double checked to make sure the A/C was not on and still cold air. Plus, the temp kept rising.
I did a few more tests, stopping, starting and driving quickly and still no change in the air temperature blowing from my vents, HOWEVER, the faster I drove the faster the temp gauge would return to normal. It was when I was idling at a red-light or stuck on traffic that the temp rises and when I'm cruising the temp goes down. It appears that this is the only factor in my temp remaining at normal.
2006 Sonata 3.3 V6 with 101,000 miles. At a cold start there is a loud whining noise coming from the engine on the passenger side. After the car warms up the whining goes away. The car has not had any noise before. It is progressively getting worse.
View 7 RepliesThis 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?
View 13 RepliesI have a 2005 Prius, purchased 5 months ago with 100k miles, and it currently has 106,000 miles.
The air conditioning blows cool, but not cold. When the A/C is turned on, it makes an unpleasant whining noise. I have a recording of it.
It did not make this noise 5 months ago, and the A/C output was colder then. I haven't used the A/C that much over the winter, but it's starting to warm up now and I've noticed it's not doing as well as it used to, and it isn't sounding very good either.
I have been having problems with a loud whining noise when I steer in cold weather (approx 35 degrees F) and only after the car has warmed up. Now, before everyone tells me about the Honda Service bulletin addressing this problem, I will tell you I had the Power Steering reservoir replaced at 65K miles, per the service bulletin. However, the problem came BACK after another 35K on the van. The dealership then replaced the inlet pipe O-ring on the power steering pump which ended up NOT fixing the problem. So I still have a fairly new power steering reservoir, a new O-ring AND the loud whine. Am I doomed to replace this every 35K miles or is there some other problem that is buried deeper than the PS reservoir? (And the loud whine you hear really is coming from the van....but soon I might be joining it.)
View 4 RepliesWhen starting the car and ONLY when it's a cold start, like sitting overnight, it makes this weird "groaning" or "whining" noise. I took a video of it because if I drive it to the dealer, then start the car there, it's not going to do it as it only happens after a long period of being off. Listen really closely after the car starts and right before the radio comes on, you will hear a faint groaning noise. It's louder in person, but this is the best I could do.

I'm trying to figure out this noise I'm hearing whenever I accelerate. I can't tell if it's the turbo or something else. It doesn't have the smooth turbo spool sound like my mk4 GTI so I'm wondering if something is wrong or this is just how the car is....
It sounds like some kind of air induction but a little clangy at the same time. I'd try to record it but I don't think my iphone would pick it up.
When the car is in neutral or in gear at a standstill there's a noise right around 1000rpm that sounds like a serious rattle or knocking. It sounds as if the car is puttering out. So essentially, I give it gas to around 2000 and then take my foot off and on its way back to idle it will putter at 1000rpm.
If the clutch is fully depressed or fully disengaged the noise is no different. I haven't noticed the noise in any other situation other than when the car is stationary but it's still a very disconcerting noise and likely just being drowned out by other noises when moving.
Does this sound like something engine related or could it be DMF chatter? Could I possibly pick up on an issue by running tests or logging with VAGCOM?
Some background on the car:
-Modified with APR Turboback and Stage 1/2 file 1.3 (the noise is present with and without tune file)
-I run 93 only
-Most miles are highway miles, currently sitting at 23k miles
-I don't notice any issues with shifting, albeit some slipping when tuned in 6th gear (no slipping when using stock file)
When I start the cold engine mine makes a loud whining noise. I took it to the Ford dealer and they said that the sound is normal and that it's the turbo's. I think I'll take it to another ford dealership and get a second opinion, The service guy has the same truck as me and his was making the same noise on cold start up and they told him it was the turbo's also. Something's not right about the noise.
View 14 RepliesMy truck's been doing this ever since I got it when the engine is cold. Haven't brought it up to a dealer yet because I'm not sure it's a real problem, and since it only does it when it's cold I'd have to leave it overnight.
It seems to happen when the turbo hits a certain RPM. I got it on video but you can't really hear it until the end when I raise the RPMs a bit.
