Golf IV / Jetta IV :: Crank / Rattle Noise When Accelerating After Engine Warms Up
Jun 10, 2009
It happens mostly after the engine warms up. When I accelerate, I hear a weird cranking noise coming from under the hood (sometimes it doesn't happen). I popped the hood to see if there was anything wrong, but i didn't find anything major (there were 3 loose screws that I tightened because I thought they were causing the vibration but the noise persisted).
I doesn't make the sound when I rev the engine, only when I am was driving. It happens roughly between 1500 and 3000 RPM. I read some of the archives to get a few ideas, but the noises people are describing are not like the one I am hearing from my car. The closest thing I found this: [URL] ....
I made a video. You'll hear the noise the loudest when I first start pressing the gas, from a complete stop: [URL] ...

I have a 2003 Jetta Gli , 24v vr6 with a 6 speed transmission.
Well this all started last night, started to drive, when accelerating , around 3k RPM I start to hear a rattle or grind. This only happens around 3k while accelerating. Once letting off the gas or pushing the clutch in, it goes away. Sometimes after 3k it'll go away.

The rattle, 1.8t GLI
-2500-3000 RPM
-Car can be in gear or out of gear, rev rattle is the same.
-Sometimes, I can hear the rattle when the car is off and I slam the door slightly harder than usual.
-My hood release cable may have been the culprit, but I could only zip-tie part of it and the rattle hasn't changed.
One really important clue is that when I have reached around the area between my engine and airbox, the rattle has gone away. So I had a bad coolant flange, so when reaching my phone down there to take pictures, I must have bumped or pressed something because the noise was gone for about a mile.
I recently had my airbox out and a visual inspection didn't show any promise and tapping on random parts didn't recreate the sound.
There is am RPM rattle near my airbox....

Watch this video. I have a rattle/noise coming from the rear right side of my car for almost 2 years now.
The part in the video is the neck of the fuel tank just behind the plastic inner fender.

Is this normal? i don't know where to search anymore to find where the rattle comes from...

I'm new to the VW family as a couple weeks ago I purchased a 2003 VR6 Jetta. So far I LOVE it and it's been by far my favorite car I've driven. About a week ago, I was visiting my parents back home (I'm a college student) and when I went to turn on my car to go back to school I received the alternator workshop message. I didn't want to take the risk so I took my sister's car back to school and my dad took my car into a local mechanic during the week.
Unfortunately, the mechanic we took the car too does not specialize in European cars (They're just a general mechanic/Ford dealership), but we didn't want to take the risk of driving a car with a potentially failing alternator to the closest VW mechanic (About 40 minutes away). The car was repaired and a new alternator added. All was going well, but I began to notice a slight "clunking" noise when first accelerating/lifting my foot off the brakes. I didn't think too much of it and it wasn't very loud nor severe. To me, it sounded like the interior plastic shifting when I moved.
Anyway, here I am a week later and I'm noticing a lot of noises that didn't exist before, including the clunk I just mentioned. I took a few audio recordings. (For the record, there is NO CEL or any dash lights currently on, thus why I'm not as concerned).
The first audio: [URL] ....
In this link, I'm driving the car around the parking lot in which I park my car here at school. It's mostly bumping gravel, but at the time of the recording I was driving very slow. You can hear a squeaking noise.
The second audio: [URL] ....
In this link, I'm revving the car while parked. Something I've noticed that it didn't used to do is rattle while idling ever so slightly (It's not audible in the recording), but in the recording you are able to hear a slight clunking noise.

Just started the other day. Ecuador codes at p030p035p0411. The noise only happens while accelerating past 10% throttle in any gear.

Okay so my 2003 Jetta GLI normally starts without a problem. But it seems like whenever it gets cold (below about 40) it doesn't even try to start. I turn the key and nothing happens, the engine doesn't crank. All the lights turn on like normal and they're not dim so I don't think it's the battery. It'll still start if I roll-start it, but there isn't any sort of hill for a few miles. Normally once it warms up later in the day it'll start up.

I have a 01 vr6 mk4 gti. When I bought the car I noticed a rattle but never paid mind to it. But now I just want it fixed. I hear the rattle come from the back of the engine near the intake manifold when I rev it a little. The most rpms the louder the rattle . I been doing some research and came to a conclusion that it could be the shift rod and bad intake bushing. But, I'll like a link on how to replace the shift rod.

When it gets hot outside and the car warms up (15 mins or so of highway driving), the stick gets extremely hard to move and it doesn't go back to center when it's out of gear. So I could push it all the way left or right without putting it in a gear, and it would stay there, it wouldn't pop back to the center like it should. It becomes really annoying and difficult to drive because it gets so stiff and hard to move, what could be causing the problem? I've already adjusted the shift linkage and that didn't work.

So I drove my car about a mile to a friend's house and when I went to start it back up 10 minutes later, I got no start and no crank. Just a single loud relay click from the engine compartment. Tow truck tried jumping it and then thwacking the starter solenoid to try and get it going. No dice. Battery seems all good.
Had some interesting things go wrong the day before which may be related to it. First, I was tracking my MPG and fuel trim on a highway trip and the trim and fuel consumption data just stopped coming in. Speedo and RPM data was still coming down the OBDII but I just assumed that my reader took a ****. Later that night I noticed that the lights on my climate control (the manual kind) went out. Tapped on it and it came back on, but only briefly. The bulb looks shot.
No engine strangeness on the drive over or earlier in the day. I drive it most every day. Has 215,000 miles on it.
I'm guessing either a short or bad starter. FWIW, I've also been experiencing the typical starter whine after starting. Was meaning to take it off and grease it. Not sure that has anything to do with it. I also tried rotating the crankshaft to make sure the engine wasn't locked up and it does turn, albeit not incredibly easily. It does have oil on the dipstick.

I have a volkswagen jetta glx vr6.Today my key wont turn (unable to crank engine) and the car won't detect my key (no remote entry/lock function).I've detached the battery.
Plugging the batter back and keeping the key in:
1. Off position causes the "Electronic Immobilzer" light to blink.
2. When in on position. no "electronic immoblizer light comes on.
3. In anycase I can't get the ignition to work.
My engine check/airbag lights are also on and my radio/ac doesn't work. Also the electronic controls for rear view mirrors don't work. Half of the tail (exaust) pipe rusted and has fallen off.On the funny sideI asked the guy at VW to appraise my jetta for a trade and he said it would be $500 for the car !! ONLY After the company official tested the car this won't start...the sales person left, since it was 6PM on Friday. I was left alone and had no option other than to leave my car at Pugi VW showroom and ask a friend for a ride...Long story.

I've noticed that potentially my heat shield or whatever guard that is 1 step toward the front of the car from where the inlet pipe connects to the exhaust system may be the reason for my rattle at 2k and 3k rpms. i think its a heat shield but I am not sure. the thing is it seems properly mounted, nothing is cracked/broken/or loose. But when I do try and wiggle it it does make a slight creaking noise that sounds similar to the rattle I get. So I could foresee this as being my issue.
But, is there anyway to fix this rattle w/out just taking off the part? i figure its there for a reason and it looks like its held on in 2 places. But they're not nuts they almost look like spot welds or something. 1 on each side. What to do?
Something to get you all in here:

My good ole trusty Prius is still running good, change the oil every month (3000-5000 miles) and still drinks oil and a little over half a quart every 1000 miles.. No big deal. Well over the last 20,000 miles I started to notice this off rattle, noise when accelerating mid throttle mostly when up hill. I thought it may have been the timing chain after changing the water pump, spark plugs and using all sorts of fuel additives, but no change.
After time it's only gotten worse, my works buys my fuel (regular 87) but one day I bought my self a tank of super premium, and hey!!! It sounded great, quiet, powerful.
My question is.. Is this because of a worn timing chain making the knock sensor do this, is this because of carbon in the engine? What should I know? I really need to fix this.

I'm sure this has been brought up before. Whats the rattle you hear when accelerating hard when the transmission shifts? Exhaust note, exhaust hardware, dsg transmission, engine sound?

So lately I've been hearing what sounds like a slight lifter knock that develops at 1500 rpm to 2700 (I have ultragauge) when accelerating or maintain speed, and it only appears when the engine is at operating temp and disappears when rpm is below 1500 rpm and above 2500 rpm my oil is running at 3900 miles using Toyota synt 0W-20 and it looks pretty clean and at high mark of the dip stick.

Hit a long 4x4 post on the freeway and bent a front rim. Was able to miss most of it but hit it with the right tires. It didn't hit anything under the car that I can tell. Got a new rim and moved the TPMS and tire to the new rim. Back wheel looks ok. Still have a low pressure light. TPMS was lit when I had the bad wheel out of the car but is now out.
Have previously had trouble with another wheel giving a warning when it was only a pound or two low. Checked all the wheels and added a few pounds to each and still have the light.
How do I troubleshoot the TPMS? How long should the batteries last - is this just normal life of the sensors? It's a 2009 model.
Also have some noise and rattles I didn't have before. Not when going straight but when turning and accelerating at the same time. Hoping its just some shields and nothing too serious... I looked and didn't see anything obviously loose so I need to dig into it a bit more.

I have a 98 f-150 4.6L 5spd that has a weird rattling noise coming from what sounds like the engine. The noise will only happen when the truck is in gear and under a load. It will not happen if I keep the RPM's low, unless I am going up a hill. When I rev the truck in neutral, the rattling noise isn't there. Also when I'm driving and hear the ratling noise it will go away when i push the clutch in(which im guessing takes the load off) but will come back when i let out on the clutch. Seems to happen most when I'm in gear and trying to accelerate.

Might be a long shot here, but I JUST had this noise/rattle pop up in my '12 GTI 6MT w/ 13k miles.
Turns out I found someone who posted a video with basically the same noise:
Another one:
I hear the same noise while stopped and revving the engine as well as when driving if I let off the throttle and let the RPM's sweep down past the same rev range (1,800-2,000). Sounds like it's coming from the passenger side area.
I'm under warranty so I'm going to take it to the dealership...but I know how they can be with rattles.

My son has a 1994 Toyota Pick Up, and it suddenly developed a rattle noise, but only when he is accelerating. I suggested he check for loose heat shields, or a broken engine mount, fan rubbing on radiator housing, but all of this is good. He had a new timing chain put in 30,000 miles ago, and a new clutch. It has 167,000 miles on it. The oil does not have flakes or coolant. It does not make the noise when not in gear and accelerating. Could it be u-joints? He said is sounds like it is coming from the Lft Front, not the undercarriage. Fuel injected. does not overheat, or lug, or lack power.
2wd. 5sd tranny.

This is in regards to my daughters 2009 I4 Sonata. In cold weather, like we are having now in Chicago. After the car is sitting all day or overnight, it will jerk (nice technical term) when accelerating until the car warms up. What is the problem is and how to resolve it?

We've got a 2012 Hyundai Accent GDI. I've been hearing the rattle "ping" when the engine is under load (accelerating hard or uphill). I've read that this is typical for these engines.
I took it to our local Hyundai dealership since it's still under the 60,000 mile warranty. They updated the computer settings and I put in a fuel additive to clean up deposits. They also told me to buy name brand gas from here on out (Exxon, Shell, Mobil) as these engines don't handle cheap gas well.
Now that I've given you enough of a backstory, here are my questions:
- For those that have experienced the rattle "ping", what did you find fixed the problem?
- Any tips or things to look out for when cleaning the throttle body etc?
