Check out how loud my cold start idle is. Still can't figure out why you can't hear the turbo on start up though. Even revving at idle you can't hear it that much. I've seen plenty of gti's with more exhaust restriction then i have and you can hear it clearly. [URL] .....
View 8 RepliesI've got a 2004 1.8T 4motion passat and when it starts cold in the morning it makes a loud noise for a minute or so then it stops and is normal again, I'vev been told by a local autoparts store that it is possibly the auxiliary/secondary air pump that needs to be changed to fix this poblem. if it is the air pump how hard is it to change and do u need any special tooling to do it or is it fairly straight forward to change?
View 5 RepliesThere is a loud ticking noise coming from an undetermined location in the engine compartment (sounds more like behind the motor). It starts on cold-start, lasts approximately a minute or so until the engine heats up. Driveability doesn't seem to be affected, and the engine doesn't have any additional weird symptoms. Some other VW owners have suggested changing the cam belt and tensioner to fix this problem, but the car has only just turned 45K miles and can't imagine that it would fail so quickly.
View 3 RepliesEvery morning for the last 3 days I've gone to go warm up my car and each time i turn on the car only from a cold start up i hear this loud high pitch noise from the motor. If i turn the car off and restart it. It goes away and the car is at perfect idle. what is this and do i have some serious problems?
Is this true? If it's only on a cold start up, and then it goes away during normal driving, you have no need to fear....that's the Secondary Air Injection Pump that turns on during cold starts, and the plastic hose just needs to be replaced.. If so where is it located so i can replace this hose.
I got the fuel pump and fuel pump control module replaced. Now I am still getting a cold start delay (5-10 seconds to start) and it has a rough idle sounding like its misfiring. This happened when i picked it up at the dealership after a new fuel pump BUT! keep in mind it has been doing this for a while so i figured it was the fuel pump.
New oem plugs and the coils were replaced when i bought the car because the coils failed during a test drive I need to scan the codes but i will post. Also this only happens during a cold start. if the car is warm and i go into target or something then start it shortly after its fine.
TSB'S I think will fix this. [URL] .....
Had the car for less then a week, i put about 100 miles on it so far and the 1.8 TSI engine a tad louder then what expect it when idling at stop light (from with in the car, windows closed). Its louder then our Smart car by few decibels and the engine is right behind driver seat. Our 2015 Camry SE with 2.5L engine is dead silent when you are in the car. Is this normal for this engine or Passat? Or this the high pressure fuel pump, injectors or chain, that are responsible for the extra noise?
View 6 RepliesThere's a thread similar to this on the front page, but I wouldn't exactly describe my issue as a "rattle".
I've got a good video of the sound it's making here : [URL] .....
It's definitely much louder with the hood up--doesn't seem quite as drastic when sitting in the driver's seat.
I've come across the thread here on the engine rattle/knock fix, but I'm not sure if this is the same thing. Would this be considered a knock?
It's a 2011 Elantra with about 82,000 miles on the odometer. It has an extended warranty on it, in addition to the 100,000 mile powertrain warranty on it, so it's at the dealership this morning.
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 RepliesMy 2013 Prius v made a really loud clicking noise this morning when starting the car from a cold start. It was less than 30 degrees Fahrenheit. The car has about 14K miles in it. Is this normal?
View 1 RepliesWe have had a few mornings (in garage) where it would seem to not really id say a knock but maybe a clicking sound and it would quit right away. This morning that did not happen so i shut the car off and checked oil it was low.
Got under the car and can not see any leaking no oil on ground. So i had a QT i put in and that seems to quiet it after a few seconds.
I called local TOY dealer and they said its common for 2010 to use some oil and not much they can do. I thought what is a little it was at the end of the dipstick.
They said they can only fill it up and then have me come back in 1400 miles and see how much is used.
I have a 2005 Accent with just over 35,000 miles on. Last night (in extreme cold here in Chicago), the car started running loud. Loud on start, idle, and acceleration - normal when maintaining speed, even at highway speed.
Since the loud sound first started, I have driven about 100 miles (had to for work, no choice). The sound is pretty much the same - definitely in the front end, and the best way I can describe it is a much louder version of the normal sounds you would hear - idle sound but louder, acceleration sound but louder, etc.
No warning lights have come on, car hasn't shown any signs of overheating on the gauges, etc. I had a somewhat similar issue with an old '99 Saturn SL2 w/ 115,000 miles - but in that instance the flex pipe had corroded and completely separated from the rest of the exhaust system.
My car is making almost like a clunking sound when starting. It doesn't do it all the time, mostly it is when its a cold start but its happening more frequent. I have the push button start, would warranty cover this?
View 2 RepliesI 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.
5.4. So I have a 2004 F-150 that just passed 80,000 miles and a month ago it started making a very loud noise on startup, but only cold startup, meaning if I haven't used the truck in about three hours. Now I went on youtube to research and found a video of a truck making the exact same noise! Here is the link:

Need to verify what this is??? Some people are saying cam phasers and some are saying I'll need a brand new engine!
My 1.8t is very rough at idle when cold, smooths out when over 1000 rpm and when at normal operating temperature. Code reader says 171 and misfires.
View 6 RepliesI've a loud squeaking sound coming from the front of the engine on cold start. This only happens when I start the engine after overnight parking . There are no squeaks when the engine is warmed up or when I start up with a warm engine.
I'm driving an 07 Camry and live in a region with hot tropical weather.

What could be the probable cause of the this and how do I rectify it?
I am a proud and recent owner of a 2015 Sonata Sport 2.0T!
Car looks amazing and am very happy with it.
But lately I have been noticing lots of drone noise coming from the engine, and a really loud cold start as well. The "cold start loudness" goes away after a little bit of driving.
Was wondering if this is just the way the 2.0T sounds, or should i get it checked?
What is this metal on metal noise...you hear it the best around the 7-12 second mark...it is especially loud on cold start in the morning when you put the car in "drive" but don't move the car forward. It also is prevalent on hot days when you park the car outside and just start the car. The sound gets louder when you turn on the a/c during the hot day.

I have a 2006 Subaru Forester automatic with about 40,000 miles on it. When it gets cold out, I notice that when I first start driving the car, it jerks/lurches and makes a loud noise when shifting from first to second and second to third. When the car warms up after driving for awhile, it doesn't do it anymore. It's much colder here (high today of zero), the car is doing this much more often. I brought it to the dealer and they completely flushed the transmission fluid (which they said looked yellow instead of red/orange??), but it is still making the noise and having trouble shifting in the cold. They said need to take the transmission apart, so I've been leary about taking it back. My husband thinks I should just drive it until it dies and then get a new transmission if needed.
View 1 RepliesI recently got my Mk7 1.8T manual brand new and have been wondering about the long cold start idle. It usually takes around a minute or two before the revs drop below 1000. Coming from a '04 Mercedes and '11 TDI Jetta, I can say those cars the idles dropped much faster. Is this normal with the golf?
View 11 Repliesjust got my R32 a year and 3 months ago and love it. I came across my first issue though a couple months ago, when i start my car on cold starts before it would of course go to the cold start mode at over 1,000 rpm's before going back down after 30 seconds and depending on the weather i'd let it warm up anywhere from 5-15 minutes.
Well a couple months ago my car wouldn't do its normal cold start routine, i'd turn it and it made its loud pitch as if it was going to do the cold start and it just immediately went down to regular idle skipping the warm up, it did this for a week before i got it checked out. I went to a shop by me and he said that it might be a thermostat sensor so i replaced it and nothing. So he then pulled my throttle body off cleaned it did the whole calibration thing or whatever its called that you have to do when unplugging them and it went back to normal!!! Well after a month (two weeks ago) its doing it again. Then he told me it might be that the throttle body has some condensation frozen and isn't allowing the throttle to open like it needs too.
I live in a suburb 20 minutes north of chicago and i don't drive the car if it snows, i keep it in my garage. I have a CAI installed on the car that i put on back in March of 09 and a flapper that i just permanently opened with an IV clamp. So i don't have any big modification on the car...yet
