Golf/GTI VII :: Whining / Buzzing Sound From Engine Upon Cold Start Up?
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?
View 13 RepliesGolf IV / Jetta IV :: 2002 GTI - Loud Whistling Sound On Cold Start
I am having an issue with my 2002 GTI 1.8T. I have tried searching for an answer to this, and found a couple things saying maybe it could be the secondary air pump but wanted to get more opinions before I go shell out money to chase this problem.
When I start up the car in the morning after having it sit overnight, the car does the normal thing where it increases rpm's to about 1100 to warm it up. During this a loud "whistling" noise can be heard. Once the car is warmed up a little bit, the rpm's decline to about 900, and the whistling sound goes away. When this happens though it almost sounds as if a valve or something is closing causing the noise to go away.
Also, I am unsure if this is related to this, sometimes when I am driving, I will be accelerating and the car seems to stop accelerating as strong as it was, boost goes down from around 8 or 9 psi to about 4 and I seem to lose power as if I had let off the gas some. When I put my foot further down the car accelerates harder again and boost goes back up.
I have already changed spark plugs, cleaned MAF sensor, and run the 3m 3 part engine cleaning kit through it.
Golf/GTI VI :: 2013 VW - Screeching Sound On Cold Start And Engine Acceleration
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.

Ford Wiring/Electrical :: 2008 F150 - Cold No Crank / No Start
I have an 08 F150 5.4L with about 68k miles. When the temperature is 40 degrees or colder it will not crank. I had the same issue with my 2005. I can turn the key and nothing, lights, radio and everything work. The dash display has dashes all the across for the miles, temp and compass. I have found out that it doesn't matter if I leave the key forward in the run position or try to crank, it won't do anything.
Battery is good and no problems with the truck. After the key is in and I give it anywhere from 15 to 60 seconds you can hear an electrical click real faintly and see the red security light come on and then the computer display comes on and then I can start with no problem? What could this be? My dealership has no clues and I can get it to act up because after I get it there it starts with no issue. The remotes work fine and this issue was why I got rid of my '05.
Santa Fe (CM - 2007-12) :: No Electrical Power / Sound When Turn The Key To Start
I have a 2007 santa fe. In the last year or so, when you turn the key to start the car - you get nothing... Like it has no electrical power, no sound, etc. However, it has never lasted more than 1min to an hour it varies. There is nothing you can do about it, just try it a couple of times, come back and try it again. It has never not started eventually. About 95% of the time, it starts within 10 min after you start trying it. However every now and again it is 10 min to an hour or more. Sometimes it goes weeks without doing it (starts the first time) and then you get a string of everyday for weeks.
The dealer can't figure out whats wrong, they need it to stop working completely. I am an engineer and have not been able to find any correlation (cold weather vs hot), not driving it for a while, turning off ac, lights, radio, using a different key. Also, during this time the battery has been periodically tested and has tested out fine.
Electrical-wiring - Ranger :: 1999 XLT Electrical Power Lost When Turn Key To Start Position
My 1999 Ford Ranger XLT, 6 cylinder, auto trans, with 134K miles has an electric problem. When I turn the key to the 'on' position, all dash lights show normal, headlights work, radio plays, etc. But when I turn the key to the 'start' position, all electric power is lost. The power remains lost until I disconnect and reconnect the battery ground wire. After reconnecting, I again have power until the key is turned to the 'start' position. I was able to jump start the truck, so I assumed I needed a new battery. I bought one a week ago, and was back to normal until today. The truck started, I drove 4 miles to the grocery store, and then I found myself back to square 1 (i.e., the no-start situation).

Can't exactly pinpoint this yet but for sure it's very consistent. Every morning when the car is cold (and been sitting for 12 hours), when I get in the car and start, within the first 5-10 seconds, there will be a long buzzing noise coming from behind the radio or cup holder area. I don't feel anything is vibrating though. It goes on for like 2-3 seconds, then off, and usually another few seconds there will be another one or two short ones. after that everything is fine
when I leave work (warmer), I don't seem to hear anything at all.
Sonata NF (2006-10) :: Knocking Sound On Cold Start
2005(its NF model) Sonata 2.4 petrol manual. 75000 miles. On cold start makes knocking sound( sound like Diesel). After coupe of minutes when warms up the knocking sound gone.
Also when i start driving( still on cold engine) i hear that sound only when i let go from gas pedal and only in range of 1800-1500 rpm. When i accelerate i don't hear that knocking sound.
I think is not belt tensioner because sound is much longer than couple of sec.
Elantra MD (2010-15) :: Chatter Sound On Cold Start
This just started yesterday on cold start and happened again this morning and this evening always after sitting for hours. I would call it a chatter sound, very distinct and only on the first start. Never heard it before. Have 97K on car, will be changing the plugs soon. Once it is warm the sound is not there on starts. It is only when starting, sounds fine once running. What would only be noisy when cold like this? Timing chain? Valves? I'm going to let others with a better sense of engines than me (my son and his friend who are mechanics) listen to it and see what they think. But it needs to be cold. Never heard such a sound on my Hondas which makes me think it may be the chain. Funny how it just came out of no where.

I've noticed that she has to turn over a few more times than normal to start up. I don't have any engine mods and I'm approaching 10k miles. I've found a couple posts where people say their cars are a little harder to start when it's cold out, but I live in Hawaii and the temperature is never below the mid 60's.
View 11 RepliesPhaeton :: Knocking After Cold Start - Sound Of Lifters Clicking?
Since I had my 40k service a few months back, I hear a knocking sound for about 3-5 seconds after a cold start (overnight is long enough). It's a pretty loud clicking sound, even worse if the car hasn't been started for a few days.
I brought it to the dealership and they said it's "the sound of the lifters clicking before they get pressurized with oil". They said the oil level is fine. Doesn't seem kosher to me - didn't happen before the 40k service.
Could they have used the wrong oil? Or perhaps didn't put something back together again properly?
Golf/GTI VII :: Clunking Sound From DSG When Cold - Is It Normal
Ever since the temperature has started dropping (<0C/32F), I have noticed that the DSG on my GTI makes sort a "clunk" noise maybe half a second after shifting. It mostly happens when up-shifting and especially when shifting from second to third gear. The noise completely goes away after the car has warmed up (about 10 minutes), so I think it may be normal.

We got a 15 F150 yay for her but I got stuck with her 113k.
So the engine makes a chain grinding sound on cold start ups and the tranny is slipping pretty hard.
Can I swap a 2.4 with a 5spd without doing a bunch of wiring?
Lexus GX 2004-09 :: Roulette Wheel Sound From Under Hood On Cold Start Up?
When I start the GX in the morning, the under hood has a sort of clicking noise almost like a roulette wheel after the car has been started and running. It then goes away after about a minute of driving.
You can't really hear it inside the vehicle, only if you're outside. The serpentine belt is relatively new and OEM.
Sonata NF (2006-10) :: Knocking Sound Lasts For About 30 - 45 Seconds After Cold Start Up
2006 Sonata LX. It's only on a cold start up and lasts for about 30-45 seconds tops..and then it goes away. Car has 74k on it. Treated well. Only use synthetic oil and no check engine lights. Last oil change I put 5w 30 in it. I know it says to use 5w 20. Could this be the problem?

My 01 accent's engine makes a clattering sound(sounds a little bit like a diesel engine) when it's first started in the morning. After warming up (in about 20 seconds or so) the sound disappears. My oil level is normal(last oil change about 4k miles ago with full synthetic oil. I normally change oil at 5k intervals with full synthetic), timing belt changed about 1 year(20k miles) ago. Should I be worried?

I recently purchased a 2006 Hyundai Azera which has developed a rattling sound upon cold start up. Based on service bulletin 06-20-002 I believe the issue is with the timing chain tensioners. I am looking at getting a DNJ TK147 timing set kit to replace them with. Do this kit contains the updated tensioners? It is located on rockauto.

I have a 2012 F-150 Platinum 6.2L. Every morning after a cold start, I get this humming sound until the engine heats up. It does seem to get a little quieter when I'm moving but not much. This only happens after the first start of the day and has only started doing this since it's been cold (20-30 F).
