Passat (B6) :: Loud Engine And Produces A Knocking Noise

Lately it has been in the 20's in my area and I've noticed on the first start of the morning the engine sounds very loud and produces a "knocking" noise that lasts a few seconds and then goes back to its normal loud idle. This only happens on the first start of the day...all subsequent starts in the day are fine. (mine is a 2007 model with the FSI engine)

Elantra MD (2010-15) :: Loud Engine Knocking Noise

My car has 63 000 km and engine is making loud knocking noise all the time. Dealer took a quick look and he asked head office. Now he wants to run some tests to see which valve is bad. He's hesitating between repairing or replacing the engine. I'm really disappointed of Hyundai quality. I really hope that I get new engine instead of poor repair job.

Ford - CV :: 1996 - Loud Knocking Noise In Engine

I recently started having a very loud knocking noise in my engine and I can't place it. Mostly due to my lack of car knowledge I can only trouble shoot so far. The following conditions are what I can really only go from:.

- when I'm in park or neutral the knocking happens in about 5 beats per second.
- while idling in gear it almost goes away.
- while driving it increases in frequency and intensity the higher the rpms, until it switches gears, then its dull until I get closer to topping out another gear.
- No real functionality of the car has changed.
- I tried doing a mild brake torque, in both drive and reverse, and the engine did not move.
- the knock is pretty hard to locate exactly but seems to come from the passenger side.

I'm hoping it's not to serious because I just filled the gas tank.

Santa Fe (CM - 2007-12) :: Loud Tapping / Knocking Noise From Engine

I am getting a loud knocking noise from the engine on my Santa Fe. The car is very low mileage of around 51K and has regular service and oil change.

Not sure what has caused this but there is a loud tapping/knocking noise coming from the engine. Have got it locally checked with the garage and Hyundai Workshop also but both have suggested that Oil levels are appropriate and they need to open engine to investigate more.

At a higher RPM the sound becomes more loud and recognizable.

Sonata NF (2006-10) :: 2.4 Engine Loud Knocking Noise When It Is Cold

My 2009 Sonata 2.4l Sonata has been making a loud knocking noise when it is cold, but it will fade to almost nothing after it warms up. I tried to make a sound clip of the noise, but it was so distorted that I could not even make out the noise on the video.

For some strange reason the noise matches the skipping problem I have been complaining about since the beginning. Yea it's still there. It sounds like it is in the valve system, not the lower end. It leads me to believe it's coming from the valve clearance/ camshaft area.

Prius (2010-12) :: Loud Knocking Noise And Check Engine Light?

So my 2012 plugin was parked for about 3 days, and when I turned it on, heard loud knocking and the check engine light came and stayed on.

When switching the car on or off, I'll hear two taps/ticks that were not there before. Loud knocking is not there now.

What can the issue be? It was very cold and snowing.

Saturn - Engines - Sl :: 2000 - Loud Knocking Noise From Engine - Tow / Drive?

We have a 2000 Saturn SL2 (120,000 miles). Last night we drove to L.A. and back (from San Diego) , so about 250 miles round trip. For the last 45 miles or so we had the radio on quite loud. At some point in that 30-45 miles the engine developed a very loud knocking noise - like rocks being spun in a tumbler - which we noticed when we got off the free-way and turned down the radio.

This noise did not effect the way the car handled as I did not notice anything when the radio was up. We have been listening to a lot of sounds and I am concerned it could be a Rod Knock - it sounds a lot like this [URL] ... from inside the car, outside it was more of a constant pinging/thunking noise - less gravel sound.

So my quandary is this, our mechanic is not open Sundays so I cannot ask him, but when we take it to him tomorrow, do we drive it or tow it? If the rod is starting to go I do not want to inadvertently do more damage by driving it. The mechanic is 8-10 miles away. We can get their either on the freeway or through surface streets.

Corolla / Matrix 2009-13 :: Loud Knocking / Rattling Noise From Engine

Fiance's 09 Corolla S just started having a rattle/knock noise this evening. car has 123k. It's clearly an engine internal sound. I believe it is coming from the cylinder head. She called me when it started making the noise, she shut it off and has only been ran enough to get it on and off the trailer.

Not sure if it's a broken valve spring or valve. or the timing chain guides? It threw a CEL light.

I ran the code on my scanner and it came back with: P0302 (Cylinder 2 Misfire)

Volvo - 740 :: 1992 - Loud Knocking Or Clicking Noise Directly From Engine When Accelerate

My Dads 92 Volvo's engine is making a knocking noise and I'm wondering what the possible causes are. He doesn't take that great care of it but it didn't over heat or anything. It sounds like it is making a loud knocking or clicking noise directly from the engine when you accelerate. It still runs but definitely has a lack of power.

Sebring - Chrysler :: 2004 - Loud Whirring Noise When Accelerate

My 2004 Chrysler Sebring with 128K miles is making a loud whirring noise when I accelerate. It does not happen when I break, coast or am idle. I live in a city and potholes are a way of life. I got four new tires in November and had the alignment checked and fixed at the time. What it could be?

Volkswagen - Beetle :: Loud Noise (Like Knocking) In Drive

I have an 06 Beetle 5 cylinder, and just the other day, after getting a new battery and they installed it, when I'm driving and step on the gas into overdrive, it gets really loud, almost like a knocking or loud muffler that has a hole it it. However, it doesn't do this when I'm in park and step on the gas. Only in drive. It still has great power, but is loud now. I'm worried that the shop did something to mess it up, but they won't check it. There is enough oil in the engine.

Prius (2004-09) :: Loud Knocking Noise When ICE Running And Car Is In Drive

I recently bought a 2007 Prius that is making a rather loud knocking noise that has me a bit perplexed. I know the noise is not normal as my 2005 does not do this.

The noise only happens when the ICE is running and the car is in drive

If the car is in park and you rev up the ICE the noise is not present. With that said I do not think the noise is isolated to something in the ICE as I think it would be present when revving the engine in park.

However is you put the car in drive and step on the brake (to keep the car stationary) while lightly revving the ICE the noise is present. The noise is present every time the car is in drive and you accelerating, even with the lightest of throttle.

It does not need to be under excessive load and with that said I am certain it is not spark knock/per-detonation of the fuel nor does it have the "pinging" sound like a spark knock.

If while driving down the road and the ICE shutdown down while driving at lower speeds the noise disappears. When the ICE starts back up the noise reappears.

BMW - X5 :: 2001 - Loud Knocking Noise In Rear End When Accelerating From A Full Stop

My wife just handed me her 2001 BMW X5(165,000 miles...new engine at 97,000) because they offered only $2000 on a trade-in. It still looks great - better than my Tundra with numerous whiskey blisters delivered by misbehaving cows. The Beemer tires are in good shape BUT the car has developed a loud knocking noise in rear end when you accelerate from a full stop (scares the heck out of you because it sounds like the backend is going to fall off). If you accelerate slowly it doesn't always knock, but other drivers try to run over you. Just had the air levelers repaired. My local mechanic thinks it is the drive shaft but not sure and won't touch it until something breaks or falls off. My question is - if it is the drive shaft and it falls off while driving - is this going to be a dangerous problem? Our mechanic doesn't seem too concerned and just doesn't want to tear it apart to check the noise. If possible (financially) I would like to repair it but will have to drive it to a bigger town to have it done. Or should we just throw in the towel and donate it to NPR?

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:

Ford - Explorer :: 2004 - Loud Knocking Noise Coming From Under The Dash

When you turn the interior ac temperature from cool to warm there is a loud knocking noise coming from under the dash. I am new to working on explorers but it seem like its coming from the black box nearest the firewall above the transmission tunnel. When you turn it to cold the noise almost completely goes away. The noise gets even louder when you mess with the selector for "max ac" "head and feet" "feet" etc.

Lexus RX 2010-15 :: Loud Knocking Appeared With Check Engine Light

Started up our 2010 RX 350 and there was loud knocking. This smoothed out after several seconds. I stopped engine and started it again. This time the knocking was less severe, but now the Check Engine light is on. Engine seems to be running a little rough as well. I have a feeling I have a bad plug or wire maybe.
