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.

Ford F-150 (2004-2008) :: Knocking Noise / Running Rough And Stalling - P0340 And P0345

I have a 2006 f150 it was making a knocking noise after the engine oil temp reached 160* and made the noise to 1700rpms. I thought it was the cam phasers so I replaced them. The truck is still making the noise and running rough and stalling but not as bad and not as often. Before it did it all of the time. The truck is timed properly. I had a new cam sensor and tried it but that did not work. I watched vct on the scan tool and both cams are in sycn.

Ford Transmission :: 2002 - Temp Gauge Move To Running Temp In Cold?

02 6.8 4x4 excursion. When I start the truck cold, the trans temp gauge immediately moves to "running" temp. Not really sure how this happens, I'd figure that if the xducer was trash it would ride all the way high or all the way low. What's happening here? I'd sure like a functional gauge...

Passat (B7) :: Engine Knocking Noise Under Acceleration?

I've noticed distinct engine knocking noise under acceleration/load especially at lower RPMs on a '14 TSI. I'm at 20k miles and wondering if cheap gas from ARCO is the culprit.

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)

Passat (B5) :: 2002 - Clicking / Knocking Noise When Make Turns

I've been hearing a clicking/knocking noise when i make turns recently and was wondering if it could just be hums in need of replacement... I have a 2002 Passat, so I think its a bit early for it to go but ya never know. If they are the hubs, what causes them to wear out so quick and around how much they'd be to replace (in parts...labor varies). The noise is only when I turn, no noise at all when driving straight.

Passat (B6) :: Engine Knocking Noise When Enter The Freeway And Accelerated A Bit

I have a 2007 volkswagen passat 2.0 L...115000 miles. Yesterday I was entering the freeway and I accelerated the car a bit when I started hearing this noise on the engine. I will try my best and describe the noise as a knocking of metal on metal. I thought maybe is the oil and changed it.

Now today I was going up the hill and accelerated the car when the noise appeared again, it happened again a little bit later, again going up a hill. There is no noise when I drive normally or I accelerate and I am not going up a hill.

Ford F-150 (2009-2014) :: 2012 - Knocking / Tapping When Got Up To Operating Temp

About 3 months ago, I bought a 2012 F-150 XLT 5.0 4x4. I bought it from a private party, a.k.a. without a warranty. It's a Ford, right? What could possibly go wrong??

Shortly after I bought it, I started noticing that it was knocking and tapping when it got up to operating temperature. Also, the idle isn't very smooth.

I have read through several threads here regarding Coyote engines with similar symptoms, and I have come to the realization that my wallet may be about to go on a diet.

Here is a video I made today, moving my phone to various places in the engine compartment, behind the drivers front wheel, and under the truck.

2012 Ford F-150 5.0 Coyote Noises 80k Miles - YouTube....

I realize that it could run a long time like this, but I sometimes take long trips and I really don't want to end up with engine trouble in the middle of nowhere.

Considering I don't have a warranty, and assuming the problem is out-of-round cylinders and/or worn valve train parts, what is my best course of action?

Passat (B7) :: Noise Inside The Car As If Electronic Motor Is Running

I am new to VW. I just purchased 2 new cars on Monday of this week. A 2012 Jetta SE for my wife and a 2012 Passat SE for me. We are loving both of these cars. I have a question though. If my car has been locked for a little while, I unlock the car, open the door, I hear a noise inside the car as if an electronic motor is running. It only last for a second or 2 and I can't pinpoint the noise. It almost sounds like the power seat is moving but I don't think that is it. Hear that noise when are entering your car?

Passat (B5) :: 2000 - Engine Makes A Loud Noise After Running

Going to take a look at a 2000 v6 passat with 130k on it. They had the car serviced at Jiffy lube and now the engine makes a loud noise after running for a minute or so. The wrong oil was used. So I'm thinking the oil pump and screen are clogged up or the oil becomes to thin when warm therefore not providing proper lubrication.

Passat (B5) :: 2003 - Making A Lot Of Noise - Engine Fan Is Running Very Fast

My '03 passat w8 just started making a lot of noise which sounds like the engine fan is running very fast and blowing like mad even though my car is not warm. It started 3 nights ago and sounds like a street sweeper, which is what I thought it was until I looked around and saw there was no street sweeper to be found. When I turn the car off the noise winds down and disappears with the fan still running just making the normal amount of fan noise so I don't think the problem is the actual fan.

Touareg :: Oil Temp Running Very Low - Subtle Rumbling?

As temperature in Michigan has dropped I am noting that my oil temp is running very low; after 8 miles in the morning, it doesn't come off the peg, and with outside temps in the 30's, does not climb above 180. My erratic mileage seems to have deteriorated with that, and the subtle rumble I noted in the first 4,000 miles seems to becoming more pronounced.

As much as I love this vehicle, I'm starting to regret the purchase. After 8 years of a flawless Tahoe and 3 years with a flawless 528i, the Touareg is frustrating me.

S-10 :: 2002 / 2.2L - Temp Gauge Running Around 170 Degrees As It Gets Cooler Outside

2002 S-10 2.2L ... Started noticing my temp gauge running around 170 degrees as it gets cooler outside. I changed the thermostat and noticed that the connector to the temp sensor was cracked, changed that too. Had to warranty replace the temp sensor because the first one didn't register on my dashboard gauge. Still didn't get heat above 150 degrees.

Warranty replace the new thermostat and still not getting heat above 150 degrees. Radiator cap test bad at 15psi, replaced radiator cap and still not getting heat above 150 degrees. The engine is running cool and the cabin heat is not as hot as it has been for the last 5 yrs. There are no engine codes stored, anti-freeze leaks and level is correct.

I'm lost as to why all the sudden the truck starts running cold and won't build heat.

Chevrolet :: Engine Is Running Kind Of Rough And Has Tapping Or Knocking Sound

It is a 2002 or 2003 Chevy truck with a diesel engine. He was going down the road the other day under normal driving conditions when the motor made a racket and then white smoke started coming out of the back like a chimney. The truck will still crank and run (and smoke), and now there is a knocking or tapping noise that is coming from the engine. The engine is running kind of rough, and has the tapping or knocking sound, but it will calm down for 1/2 a second at which time the rough idle and noise stop, but quickly return. There is no engine code showing, so my code reader is useless. I once had a Chevy 350 with a spun main bearing that sounds similar, but the motor didn't idle rough or smoke. I don't know enough about diesel engines. I was told there was a possibility of a bad injector pump or bad injector itself. Is there any way of testing this yourself, or does it require a shop trip?

Golf VI R :: Rough Running - Knocking Sounds Coming From Engine At Stop Light

I started my car this morning and drove to work. It's not that cold. I heard knocking sounds coming from the engine at a stop light. I lightly tapped on the accelerator to hear it better. My commute is short (3 miles), so I gingerly cruised there. I didn't try to accelerate and it didn't seem like I was suffering from loss of power either. I opened the hood and let it idol at work and couldn't really hear the knocking sound.

I downloaded the code when I got to work. After that I started the engine again and it sounded pretty normal. I'm due for my oil/filter change (~5500 miles).

Here are the codes. Any reasons to worry, or is this an one-time thing?

2 Faults Found:

001322 - Camshaft Adj. Bank 1 Intake
P052A - 001 - Cold-Start Timing not Reached

Freeze Frame:
Fault Status: 01100001
Fault Priority: 2
Fault Frequency: 1

Ford 6.0L Power Stroke Diesel :: Running Hot - Temp Alarm Went Off?

So the other day while towing my 5er my temp alarm on my CTS went off at 220. I let off and it cooled down, but not where it usually runs. Unloaded it will run at 200 where it usually runs at 180 or less. Its an 06 EGR deleted, coolant filter, studs, the works. Water pump? Thermostat? Coolant level is ok.

Ford 6.0L Power Stroke Diesel :: Oil Temp Running High

I recently noticed on my truck that my oil temp was running high, I would go down the interstate at 75 mph and the oil temp would get up to 215-218 while my coolant temp would sit around 192-196. So, I took it into the shop and was told it was most likely a bad oil cooler and had it replaced 2 years ago when I had my injectors and gaskets replaced along with my egr deleted. So, got the truck yesterday, going 60mph down the highway, truck ran an oil temp of 192 and the coolant at 188. Was great, but later on once I got to the interstate going my 75 mph, The oil temp jumped to 209 and my coolant sat at 192. Not sure what the deal is, was told the oil cooler was replaced and wanted some input on what else I could be looking at. I currently have 5w40 synthetic oil running in it. I have an EDGE CTS tuner on it and tuned it back to stock mode, but oil temp still jumps up to 209 and coolant remains around 190-192.
