Yes. One of your brake pads on the caliper side of the brakes had been worn so far down it popped out of place. Now you are stopping using the caliper piston against the brake rotor. You will now have to not only get the brake pads and rotors replaced, but the caliper as well. If you cannot fix this yourself, you should get the vehicle towed to a repair ...

It is the sound of the fuel pump priming and pressurizing the fuel lines, which is absolutely normal. VW likes to use the opening of the driver door to trigger fuel rail pressurization. In fact, one could use the absence of the sound of the fuel pump as a tell-tale sign that the fuel pump relay is not functioning properly. As @Paulster2 points out, either ...

It sounds like the brake pads have either completely worn through or otherwise failed, your car is not safe to drive at all. In this case you will certainly need new pads on both sides and possibly new rotors (disks) if they have been scored by metal/metal contact. Depending on exactly what has failed the calipers and pistons may be ok but they need to ...

From personal experience, I'd replaced ALOT of these working at the dealership. It wasn't just the accords either, it was quite a few Honda and Acuras that used the same design and power delivery system. The most common issues I saw out of probably close to 100+ failures of these was: Ground strap on the starter becoming corroded. Bad ground to engine ...

Diagnosing noises when you're thousands of miles away isn't going to be easy, but here are a few tips to help you out: remove the serpentine belt and run the engine If the noise stops, you know that the noise source is something that is running off the serpentine. inspect the belt for loss of tension Loose belts are notorious for squealing spin the ...

It is quite likely the work performed has introduced a subtle air leak that only manifests itself under high boost. Pressurizing the intake tract with the car off will help you identify the source of the leak. A hose fitting that isn't honked down all the way will exhibit this kind of behavior under boost. I like how Jafro figured out the source of his ...

For anyone who has similar issues I had a similar issue however I don't think it was exactly same. I tried the steps in the accepted answer with no success. Research on my own I tried different phones and noticed that some would have the static at low volumes and other would not. I looked online and sometimes the phone can cause this to happen. How I ...

It sounds like a valve adjustment is required There are many items that can make a 'ticking' noise that is tied to the RPM of the vehicle. Having the sound match RPM's certainly gives a clue that it is associated with the operation of the engine. Many times a valve adjustment is required. This is a component of a regular maintenance schedule for almost ...

it sounds like valves Your valves are at the top of the motor under the black cover. They are reciprocating devices, they move in and out and are operated by a camshaft that is spinning at half the RPM of the crankshaft. As your cam rides on top of a tappet or 'bucket' the clearance between the cam and the tappet/bucket can increase or decrease over time. ...

While @DucatiKiller is most likely correct, there is another possible reason for this noise, that being a leaking exhaust manifold. If the exhaust manifold is leaking at the head, it will make an almost indistinguishable noise from that of the tappets. It too rises and falls with engine RPM, just like tappet noise. It comes from the same basic location (head ...

Since when a wheel bearing goes bad you can feel it more than you can hear it, and there usually isn't any deflection in the wheel itself until the bearing is pretty much shot, the way I usually check for the bad bearing is with an automotive stethoscope: What I do is this: Put the car up on jack stands Take the wheel off of the car (if you need to ...

Before I begin I must say that any accident of any degree cannot be diagnosed on-line and definitely needs to be taken to a mechanic for through inspection. However , based on your description I have a few points which might be helpful. If your exhaust got louder and you experience loss of power check if the exhaust is not damaged, If it has cracked then ...

I would venture to guess that it is a completely random, and in no way threatening plastic trim piece/wiring harness/adjustment lever under the steering column that is rubbing or vibrating against it's fasteners or another trim piece. It is completely intermittent because sometimes it catches itself in such a way that it doesn't vibrate, or it could be ...

Based upon the information you've provided I can think of two things that may create the "medium frequency whirring" sound. 1. Low Power Steering Fluid When your power steering fluid is low the fluid cannot absorb sound and what you hear is the pump possibly going bad as a result. Sometimes, when the fluid is just low there will be audible component ...

Your problem could be caused by two things. A shitty car charger, they are not all created equal, or a ground loop. As far as the charger goes try several different ones, name brand ones tend to be the best (htc, iphone, samsung, etc...). If the problem goes away then it was the charger. As far as a ground loop, what happens is that the ground potential ...

Is the curve a healthy one for an alternator? (Keeping in mind the headlights were on low beam during the test as well as all marker lights) I would consider this about normal and quite healthy for voltage output. You'd expect the voltage to go up somewhat with the increase in RPMs. Is the whine my early warning that one of the bearings in the ...

It definitely does sound like a bad wheel hub bearing. Classic pattern of woob-woob-woob-woob. The sound is made as the bearing inner race wobbles around the outer race. This is a safety issue. Replace as soon as possible. Did you take a look at the CV joints? A bad CV boot could have damaged the bearing by filling it up with gunk (a mix of dirt and ...

I found a great article out there on the interwebz which explains this very well (and confirms my line of thinking) for the BMW M62 engine. I'm sure the explanation is pretty much the same for other engines of the same type. Basically, the author of the article states these engines do not have rocker arms, but instead uses a cam on lifter on valve setup. ...

Set the valve clearance with feeler gauges. Exhaust .012" Intake .010". 30 yrs of Honda and I still do not trust any other method. If one of my employees does not use gauges we will be having a chat... Rod knock is usually much more evident on acceleration and not heard at idle until the damage is quite advanced. The noise can vary but is usually a lower ...

Seeing as how changing your thermostat is a variable in this. This sounds more like an HVAC or blower motor issue. If the thermostat fixed it and you now have issues again during winter along with clunking, I would say it's probably a compressor or blower motor issue. Those can cause a clunking sound. Typically you can diagnose a problem with these sounds ...

The car usually has trouble starting on the first try. It'll start and immediately stall. If it's warm out, I can pump the gas pedal once and it starts up fine. Otherwise, it might take a couple more tries and I have to let it warm up for 30 sec. to a minute before I can drive off (otherwise it stalls as soon as I put it in gear and push on the ...

My 92 Civic VX fan was intermittently noisy. Removed it and discovered it was 1/3 full of leaves. Cleaned it and works like new. Took 15 minutes (would have been half that time if I was as limber as I was 30 years ago).

If I am not mistaken the 2001 Yamaha Diversion has a clutch cable and does not have a hydraulic self adjusting clutch mechanism. This was my son's first motorcycle and we experienced similar issues with his. I will say that this model is bullet proof. Especially the 8 valve air cooled version which you have. Throw Out Bearing If your throw out bearing ...

I have three Wranglers, and there are plenty of places on them to squeak, and not all of them have grease nipples. The most common places that will cause a squeak on the Wrangler, in order of likeliness) Track Bar bushings (rubber bushings, no grease point) Tie rod ends at the axle (usually grease points at both ends) Drag Link (usually greasable at both ...

tl dr; More pressure = less noise. Here is a pretty good write-up about the affects of tire noise. In the write-up it states the following: Tires running higher inflation pressures generate lower noise levels compared to those with lower inflation levels. This holds true to my line of thought because a flat tire (or very low tire) will make a lot ...

I would check/replace the strut's top mount. The rubber may be worn allowing excessive movement at the top of the strut. Try pulling in the strut to see if the top mount moves excessively. If the rubber looks OK and nothing is worn, try loosening the mounting bolts and see if it can be relocated slightly to move the spring away from the panel it is ...

Unfortunately I can not pinpoint your issue, but will give you the information I have. Since the noise is not speed dependent, yet does not exhibit itself when the transmission is not engaged (either through disengaged clutch or left in neutral), it is my approximation the noise emanates from the transmission. The noise sounds only when the transmission is ...

Carbon-metallic Brake Pads If you do have carbon-metallic brake pads, especially high performance ones like you might find on an Audi S4 (although I can't say for sure), the material that they are made out of do tend to be prone to noise which is an artifact that occurs from the manufacturer trying to optimise for braking efficiency. How to Fix Brake Noise ...

The culprit in this specific case was the steering pump pulley - it developed a slight play along the axis and the auxiliary belt started rubbing the sides of the pulley ridges. Since no one has a more comprehensive answer for similar issues I can try answering it myself now that I am more knowledgeable in this area. Causes of the noise The auxiliary ...

You should check belt tension and visually inspect the pulleys for rubber deposits. You can check pulleys by applying a load to the pulley and spinning it. You probably need to include which transfer case you have on the vehicle by looking at the stamped plate. How much vacuum is "little vacuum"? If you have a NVG231 there should be engine vacuum (roughly ...
