Passat (B6) :: Loud Clunk Sound During Some Spirited Driving
Apr 28, 2008
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?

So last night I got on it a couple times coming home from dinner (just a couple WOT from 25-60) and this morning when cranking it up I noticed the engine developed a rough idle. Also, the typical whistle I hear that kicks in a few seconds after startup is not as pronounced as it was.
With my scangauge hooked up I checked out the ICV values (which appear to be good .25 before startup .84 at idle) ICP (22% at idle 48% at 3-4k rpms) and FICM Voltage (47.5v consistently).
The truck is a 2004 6.0L Excursion (255k miles, w/ headstuds, EGR delete, 4" exhaust, blue spring mod installed yesterday) with a rev-x in the oil and ford cetane booster at each fill-up. One of the issues that I'm currently battling though is that the last owner bought the truck with all mods already done, so he wasn't knowledgeable as to what is done. There's definitely a tune on the truck as well (seen boost upwards of 38lb), but no tuner with the truck (something I also have to address).
Here's a video of startup : [URL] ....

Our excursion usually sits unless we are towing or need to haul a group of people. The past three days my wife has been using it as a commuter. Yesterday she told me that two times at start-up she has heard a loud clunk/thump sound coming from the rear of the vehicle. At first she thought it was happening when she engaged the brake to put it in drive. Today she called me and told me the sound came just after start-up while the vehicle was warming up before the brake was applied. What this could be? I wish I would have observed it so I could give more details.

Here is my new to me 03 Jetta 1.8T Wagon. This all started yesterday driving down the highway at about 65, I drove over a bump and there was what felt like a jerk. I lost the radio right away and when stepping on the accelerator it didn't seem to go over 3500rpm. I got a few miles into town taking it easy and it died as I pulled up to a stop sign. I was able to get a jump and get it running again.
This was the first jump of the day...When we popped the hood to jump it I noticed that the red wire coming off the positive battery terminal to the power block was frayed and corroded, so I cut the bad end off and stripped the wire to get a good connection. Left the car on a battery tender just to make sure the battery was charged and came back after a few hours and it started right up. Problem solved right?! Wrong...
Probably 10 miles down the road the same thing happens, a jerk or clunk sound, lost power and the call stalled out. Called family that was close by and tried to jump it again 'cause that worked the first time... Got a few miles down the road and it happened again!
Here's a picture of the gauge cluster and all the lights that lit up.
Long story short the car had basically no lights, power, for the windows/radio/turn signals/headlights etc... but was putting along at about 5 mph. I was out in the country and about 5 miles from home so I was just focused on getting it in my garage. It died again and a jump wouldn't even get it going the next time. I did some reading on my phone and it seems like the power block can be problematic, I took a picture of that because there is some obvious melted plastic on the large black wire.
I have a friend with a vag com, and he was able to come out and read the faults and then clear them and the car started right up just fine off a jump pack. We did get it home, but today I'm getting the same issues. I am trying to trace that black wire to its origin to see if there is corrosion or a loose connection there but I have no clue where else to start....
I start a new job on the 21st of July and this was meant to be my commuter as my truck gets terrible mileage...

So as of lately i have noticed what i call a "clunking" noise. It seems to be coming from below the car and i cant tell whether its in the front or the rear, but the best way i can describe it is it sounds like when the Original ABS came out. For example on the first gen ABS you used to have to "reset" it after a hard braking. to reset this you had to put the car into reverse and push the gas and then hit the brakes as to flip some kind of switch cause then you would hear that CLUNK noise.
So to the point I am noticing this noise randomly while i am driving the car and the brakes and calipers are wearing fine and have plenty of pad and rotor left. I have no engine codes on the display and when i run vagcom i get no DTC's. I have cleared out my trunk thinking something in the trunk is bumping around and that didn't solve it. Could it be motor mounts? Downpipe? Worn rubber exhaust mounts? Tranny?

So I know the 2013 GS (or many GS in general) have had complaints of squeaks and rattles. My GS has a couple but are very minor and only occasional.
I do have one noise that seems unusual though. When I am driving and drive over moderate bumps in the road, I hear a muffled clunk or thunk type of noise only from the rear passenger area and never anywhere else.
My car is a stock CPO 2013 F sport and not lowered or anything. Stock rims and tires. The shock does not seem to be leaking.
The noise happens regardless of if I am in regular or sport+ modes. Was going to mention it to the dealer at my next oil change and door trim replacement appointment I need to make Ina couple months.

I'm getting a clunk sound from my Passat's front left suspension when making turns. I've found info on how to diagnose control arms and I plan to jack the car up tomorrow and check it out. But how would I diagnose a tie rod end problem?
My Passat has 53,000 miles on it.

On my way home from work the other day my 2000 7.3l started making a humming sound while driving. I noticed that it was shifting harder and it began to slam into gear when I would take off from a stop. By the time I pulled into the driveway I had to be half way into the pedal to keep it moving. I shifted into reverse and it clunked loudly and didn't want to back up. I don't know much about transmissions but I'm thinking that it's probably shot. I'm hoping that it's something other than a complete rebuild but doubtful.

I have a 2008 Prius with 111,000 miles on it and lately, I hear a loud chirping, whining sound that is louder under acceleration and seems to vary only according to acceleration or deceleration. Acceleration makes a louder sound. The noise does not occur when vehicle is cold and first driven. It's only after it's driven for awhile and things are warmed up but then again, it doesn't always do it even though it's warmed up. Not sure I could reproduce the sound if I brought it to a dealer for service. When the noise does start up, it's very apparent and loud and then, after awhile, it goes away temporarily only to start up again.

While driving our car I heard a loud popping sound and had to call roadside assistance. I was informed that the frame had cracked which probably caused the axle to drop. The car is part of a class action suit for corrosion of the frame. Customer service says that they will cover any damages to the car as a result of problems with the frame. If the local Hyundai asks for payment, Should I have the car fixed and submit the bill to the main office for reimbursement?

I've noticed that when I've driven, park the car in the garage, turn off the engine, trans in park, a loud popping sound coming from the transmission (?) It sounds as if the car is clicking, popping into gear, although it's in Park. The garage is level and the car is not being moved in any kind of way. I sometimes sit in the car to finish a song or a phone call and I noticed this yesterday.

Driving my golf to take daughter to airport, all or a sudden there is this very loud metal scrapping sound. So I pull over and see this metal bat hanging from under the car and rubbing on the ground. At this point I'm not sure what it is and cant really budge it or dislodge it.
Anyway called for roadside assistance and a towtruck comes. The guy lifts the car a bit and is able to free this metal rod. Its about 1.8m (6ft) long and about 5mm thick (approx). Couple of photos below. Not sure if its part of suspension, steering or something else. Did have a mobile mechanic today doing some work on the cooling system (flange) he had to jack up the car.

I have a 1999 Toyota Camry 2.2 4cyl with 220K+ miles.
I was driving on the freeway when I heard a loud "POP" and rat-tat-tat cracking sound from my engine. I managed to pull over on the road where the car rolled to a stop. I tried to start up the car and the starter cranked, but the engine wouldn't start.
I thought it might be a broken timing belt since a similar situation happened to a family member (who was driving another Camry) a couple of years ago, and we were able to fix the car by changing the worn down timing belt. So today I spent all day taking things apart and finally got to the timing belt, but to my surprise, the belt looks completely fine.
I fear I might've actually blown the engine but don't know how to diagnose this.

I have Camry 2002 LE which has 110000 miles on it. After last winter in Pittsburgh, first time I drove it for 200 miles continuously and all of sudden the engine started making very loud sound after 2-3 hrs drive and I had to pull it off.
When you give more gas, the sound increases even further. It is very load and unbearable. I called AAA and mechanic advised something wrong with engine and I cannot drive it anymore so have to tow it.
The sound is coming from engine and it is very very load. I will take it to mechanic tomorrow but what would have gone wrong. Is it the end of my car life?

I was driving on the freeway(70mph), when a loud pop noise (sound of a blown tire.) Felt like a wheel bearing seized up then felt rough on the road. Got off the freeway and everything looked normal from the outside. No smell/smoke. While driving home on the back roads, i was hearing a rattle from the trunk area.
Lifted the car and noticed a little bit of fluid on the front of the differential. Didn't find any leaks or puddles. Took the fuse out for the haldex, and drove it around, still feels the same but still hear the rattle. Hoping its not the differential but haven't drained any fluid yet.
Ok, well never mind. brake system locked up on me.
