Phaeton :: 2004 - Sound System Malfunction / While Putting CD Into Player Yield Clipping

Have an early 2004 US Phaeton with the smaller sound system. Everything works normally on the system, but when putting some commercial CD's into the player can yield some really nasty clipping (clicking on drum-beats or other high-frequency sound) on the loudest sections. The clipping only occurs on the loudest sections, irrespective of how high the volume control is, and it only occurs when listening to the CD.

This is either a defect in the digital/analog converter in my particular unit, or it's a design defect with the whole series. For techies, the highest bit (#15) in the D/A is feeding an overload signal into the analog path of both channels. This symptom also could occur on CD's you burn yourself if you tend to record your CD's really loud (right up to the limit of CD dynamic range).

Passat (B5) :: 2000 - Loud Noise Like A Motor Whirring Under The Hood

I have a 2000 VW Passat 1.8T Automatic. During a cold start, I notice a rather loud noise like a motor whirring that lasts for approximately 30 seconds. My RPMs also run about 200 higher than idle during this time. After the 30 secs the noise goes away (sounds like this motor powers down) and the RPMs return to normal.

It doesn't happen every time I start the car, just when it has been sitting for more than 4-5 hours or overnight. What this is and what if anything I should do?

Ford Super Duty (1999-2016) :: 2011 F250 - Fan Is Making A Loud Sound As The Motor Is Accelerating

Picked up a new to me 2011 F250 Lariat. She had a few odds and ends to take care of, but I was ok with that. So far I fixed the reverse sensors (2 were out) creaking in the back (leaf spring bushings needed a little Lithium Grease) Squeak in the back (tailgate step needed a little greasing). Now on to my next problem!

This is my first 6.2l (first f250 in general). Truck starts up great and idles quite. Taking off driving, it sounds loud as hell under the hood. To me it sounds like the Fan is making a loud sound as the motor is accelerating. It is more noticeable when you really floor it. Prior to this I owned a 2010 F150 and I know stomping on it the motor really revs up, but this other sound to me isn't right/normal. Googling around, the closest I found to it was:

Loud "Air" Sound Upon Accelerating 2002 FORD EXPEDITION - fan clutch! - YouTube

Granted it's for an expedition, but the sound is damn near identical. Looking on youtube at 1 or 2 videos of a f250 doing a 0-60 all I heard was the sound of the motor revving, so that has me convinced the sound I'm hearing is not normal. I'm 99% convinced it has to be the fan clutch.

Passat (B5) :: Loud High Pitch Noise From The Motor On Cold Start Up

Every 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.

Passat (B6) :: Electric Motor Sound When Turned Off The Car

It's an odd small electric motor sound. It happens when I get into the car and tonight I heard it when I turned off the car (had radio off) which that one was longer and had different pitches. It sounds like the power seat is adjusting but it's not. It's driving me nuts that I don't know what it is!

Passat (B6) :: Whistling Sound From Blower Motor

I have a strange whistling sound coming from the blower motor inside the cabin. Sometimes it stops when I accelerate and sometimes it stops when I come to a complete stop. It's very strange. The heat seems to work just fine and I have no VAG COM errors. What this could be or how to fix it?

Passat (B6) :: Loud Clunk Sound During Some Spirited Driving

It seems the car has developed a loud "clunk sound" during some "spirited" driving. It is also felt near my left foot when this happens. It will happen, lets say, once during a right turn. Then, if a left turn is soon followed in the same "spirited" manner, another clunk will happen. There may be a less loud clunk once in a while during a quick take-off from a light. Is something shifting around? Is this cause for immediate action or can I wait until my 10k service in about a month?

Passat (B6) :: Random Loud Knocking Sound On The Front End

Experienced a loud "knocking" sound coming from the Passat's front end? It doesn't happen very often, but when it does, it sounds like it's originating from the front axle area. I haven't pinpointed a pattern yet, but it seems to happen when there's additional weight being put on the front end--i.e. at the point of going down a hill to flat, or when initially going up a hill from flat. And no, I'm not bottoming out. Basically, the knock sound is so random/loud/alarming.

Prius (2004-09) :: While Clipping New Bulb Lost Headlight Retention Clip

I tried to replace my driver side burnt-out bulb today. While I was trying to clip in the new bulb, the metal clip somehow came loose and dropped down into the car. After poking around for an hour, I can't find it. I put back the assembly (without a bulb) and am pondering my next moves. Two big questions:

Is there anywhere I can get a replacement headlight retention clip? Is it safe to drive around without a bulb in one side? Or should I put in the old (or new) bulb and let it jostle around without the clip.

Prius (2010-12) :: Loud Rumbling And Shaking After Starting Motor

I have a Prius III 2011. I've had it for 10,000 miles and have had no problems at all. Yesterday, when I started the car, it made a loud rumbling and the engine shook, when it transitioned from the electric motor to the gas engine.

It did that several times when I restarted and then went away. The problem happened on the transition each time. Electric motor came on perfectly and then ten seconds later it was like an earth quake under the hood.

My dad watched the engine and said that it shook really hard. At first he thought it might be a fan belt but then he said it seemed more like water or something may have gotten into the gas tank and it was choking...

Ford F-150 (2009-2014) :: Loud Noise Coming From 4.6 Motor / Missing

I have a 2010 ford f150 with a 4.6 engine. it has developed a loud noise like a diesel on steroids and also sounds like its going to fly apart and it also misses when it does this . now this is how I have narrowed it down to make it happen because it does not do it all the time. it mainly does it to and from longer trips like 45 minutes or more then coming into traffic to a crawl or idle it will start making the noise . also when I pull into my drive and go from drive to reverse and go to back up it will also make the noise. I have no lights on the dash or codes. could this be a coil pack ? I had a coil go a few years back but it acted up under load on a hill and just missed with no noise.

Celica :: 2002 - Power Steering Loud Whining Noise After Motor Swap

I am a Honda/Acura nerd. Decided to buy my friends 02 Celica that had piston slap from the famous oil consumption issue i learned about. Did a bunch of research and swapped in a Corolla motor. Everything seemed to go as normal, its in and running just fine. Only problem is now the power steering pump is making a very loud whining noise like its low on fluid.

Now first i must say the car ran, drove and turned just fine before the swap. No noises or issues aside from the piston slap. On the 1zzfe engine there is 2 bolts to remove the power steering pump and move it out of the way, easy enough.

My question is how did the power steering pump manage to get damaged? I've inspected under the car a bunch of times, inspected the top of the power steering pump, inspected everything i could looking for a problem. I just don't see any...no smashed hardlines, no leaks, has plenty of fluid, sensor is firmly plugged in. I notice when it is making the whining sound, the hardline that connects to the top of the pump is vibrating, which is what is making the sound i guess...if i crank the wheel all the way to the right or left it doesn't make the noise at all...
