Passat (B6) :: 3.6 - Rhythmic Knock Coming From The Motor
I recently bought a 2007 Passat 3.6 and am now noticing an odd sound from the motor. When I am at parking lot speed, just barely giving it gas (1000 RPM or so) I can hear a dull, almost rhythmic knock coming from the motor. It's similar to an exhaust "lub-dub" sound, but not. I brought it to the dealer under it's bumper to bumper warranty and they told me that it is a normal sound for the vehicle "in this configuration". Is this really normal?? I'm worried that it isn't, and just about the time I'm out of warranty it'll be a big deal. The car has 32K on it and the engine has 20K. Yep...it blew and was completely replaced at 11K.

SE with Nav & Sunroof, when opening & closing Tilt the motor vibrates and the hinges squeak, after the dealer apparently lubricated the s/roof the squeaking etc is still happening..
The service manager says it's the rubber water seals closing or pulling apart! he says that after lubrication just 1car wash will enable the squeaking to return!!!!!
He also says that the trunk on my wife's 2012 Jetta should not fully pop open when using the keyfob, buy it popped fully open for 2 months - now it's just lifts a little..did VW reprogram via the internet? or whats the story...........
Subaru - Forester :: 2002 - Check Engine Code For Knock Sensor - Motor Mounts?
2002 Subaru Forester I took my car to the Auto Zone to read a check engine code. It came back as being a "knock sensor". Besides that I needed a battery, and when the guy was putting it in he said my engine was moving too much and that I probably needed motor mounts.
I was looking at a discussion back in 2010 and the Subaru specialist told the person needing motor mounts is rare for a Subaru, is that true? I'm taking it to a mechanic, what should I expect? how many motor mounts does a subaru have?
Camry :: 2007 XLE V6 - Loud Knock In Engine
I have a 2007 Camry XLE with 30,000 miles on it purchased new.I stated it up the other day after setting all night it had a very loud knock in the engine I shut it off and had it towed to the dealership. They started it up and wanted to know what happened they said it sounded like a rod out. They keep it several days and ended up doing a top engine flush and then replaced the spark plugs. They said it was a carbon build up.I asked if they suggest any thing to keep this from happening and they said they do not recommend using any thing. I thought carbon deposits were supposed to be a thing of the past. Does this still happen.

So this just started happening last night and I haven't had time yet to get the car in a rack. There is now a fairly loud knock (changes frequency with speed) coming from under my right foot while coasting in gear. It does not affect steering, braking, handling (from what I can tell), or acceleration. The knock it not there while coasting in neutral. My concern is that it may be a mount that is loose.
View 4 RepliesPassat (B7) :: 2012 - Loud Knock Noise From Underside Of Car
Passat (2012 3.6 SEL, 7500 mi) making a loud knock noise from the underside of the car. It happens, without fail, every time I pull it out of my garage, and often when I'm coming to a stop or pulling out of a parking spot, etc.
I have taken it to the dealer numerous times, only to have the "failed to replicate, operating as designed" on the service tag. The car has been in for so many other things, this is just another issue I mention to them every time. Since the other issues (aside from the rattles) have been fixed, I'll make this my primary concern...until something else wiggs out on the car.
Tiguan :: Front End Clunk / Knock / Loud Pop On Deceleration
The car: 2012 Tiguan SE 4mo (auto)
The noise: there is a loud pop/cluck/knock from the front drivers side footwell, can sometimes be felt in the pedals
When it occurs: Most frequently it occurs on deceleration. Letting off the gas, there is a slight delay then the noise. It doesn't happen every time. The intensity of it is very sporadic and unpredictable. In stop and go traffic, it is typically the worst, gently accelerate, let off the gas, loud clunk. During other normal driving, accelerate up to normal (55mph) speed, let off gas, quieter clunk, intermittent. Infrequently it makes the noise when I shift into reverse. I can also hear it faintly when i start the car sometimes.
There seems to be very little correlation to vehicle speed and the noise. It is typically louder at low.
Golf/GTI VII :: Loud Under Hood Squeak At Idle
A relatively loud under hood squeak at idle has developed.
Applying some pressure to the metal fuel lines by the engine works.
Is this noise associated with the TSB that addresses the fuel line noise under the passenger seat ?
It seems to be a different issue.
Golf V R32 :: Squeak Really Loud In Drive Through And When Go Slow
I remember reading on here about why our cars squeak really loud in the drive through and when we go slow etc.. I remember some people saying its the exhaust hanger and some said they were told its because our transmissions use wet clutches or something like that. The past few days I've been driving without my music and I've noticed that is a really loud squeak and its really starting to annoy the hell out of me.

1987 Buick LeSabre V6 w/automatic transmission. Suddenly getting a fairly loud "knock" from somewhere in the engine area. Only present at low rpm or idle, goes away at higher rpm's. Does not seem to be related to vehicle movement. "May" change some with gear shifting but can not really tell. Oil is full and no "idiot" light warning. Timing belt recently changed. Car seems to run fine, just making noise. Any clues???

View 19 RepliesGolf/GTI VI :: 2004 - Single Loud Knock From Front Left Wheel
I own a 2004 VW GTI VR6, with 70k miles. i bought it used (at 40k) from carmax. Ever since I've owned it I have had a problem with a single loud knock sound i can hear from my front left wheel.
it happens in two scenarios1) when i back out of a parking space and start turning my wheel - it's only a single knock (hence i don't think it's the CV, and its been pretty constant for at least 2 years), and happens at about halfway through the steering wheel travel.2) it also happens when i accelerate hard, or decelerate. it's a single knock, or pop, or clunking sound. it almost feels like something is loose, or reseating itself as the car puts pressure on the wheel as i accelerate, and then again once again when the car decelerates.
it's pretty damn loud, and disconcerting... i can feel it in the steering wheel as well. it seems to be louder when the car has not been driven for a few days.
I've taken the car back to carmax several times over the past three years but they have not been able to find the fault. they have replaced my engine mounts twice (in 30k miles that I've had the car), which i also think is a little weird. they have also replaced all the tie rod ends, etc. - all the obvious stuff.
I am at my wit's end here - carmax pretty much think I'm crazy, and my warranty has run out, but i think I've bought a car that was in an accident - i'm expecting my front end to fall apart one day as I'm driving...
Ford Excursion :: V10 - Engine Knock / Loud Noises Coming From Under The Hood
The wife drove the Excursion (V10) to work today and it ran normal and didn't have any loud noises coming from under the hood. When she started the engine to return home it immediately started knocking. This is not a ping, but a knock. Not a loud heavy knock, but much louder than a ping. It has a fast frequency, seems too fast to be a rod knocking. The frequency is similar to a valve issue, but the knock seems to be too heavy for lifters. Oil looks good. Just changed out 2 weeks ago. Truck is driven everyday.

I don't know if it could be pads, rotors, calipers or something else. Just noticed it today. It squeaks while driving and then when I hit the brakes it lets out an even louder annoying squeak. Obviously I was thinking its something involving my brakes but why would it squeak while I'm just driving? What could it be?

View 6 RepliesFord - Explorer :: 2002 XLT - Loud Squeak At Higher RPM
I have an 02 Explorer XLT with 164K miles. I am the original owner. Recently the passenger side of the engine compartment has developed an annoying squeak. The pitch is associated to the RPM of the engine. The higher the RPM the higher the pitch of the squeak. It seems to be louder near the underside of the front then near the top. I replace the serpentine Belt Tensioner and that did not fix it. The belt looks good, no cracks or frays, and I sprayed some belt dressing on it but it made no difference. What do you recommend I try next ?
