Passat (B6) :: 2008 - Making Clanging Racket Sound Like Old Diesel On Cold Start?
Jun 10, 2013
Yesterday evening I started up my 2008 variant 3.6 4motion after it had been sitting for about 24 hours. It started up right away but immediately started making a clanging racket that sounded just like an old Mercedes Diesel that needs a tuneup. It was such a loud and odd noise that at first I thought it was another car or truck pulled up next to me!
After about 5-10 seconds it settled down and idled normally--no warning lights, no leaks, no performance issues. I took it on a ~7 mile mixed freeway and surface streets drive with A/C off and on and it ran like a champ, then it sat again for a couple of hours before the return trip and started up & got us home with no problem.
It definitely wasn't the normal injector noise and it wasn't the emissions SAI (Secondary Air Injection) pump either. Since it's a 2008 (and since it's still running) I'm ruling out the oil pump bolt. The accessory v-belt and tensioner look fine and engine oil level/pressure are good, too.
We're experiencing our first real hot weather of the summer (low 90s) and it had been baking in the sun all day, so I'm wondering if the temperature caused pinging on startup before the ECU adapted?
Today, of course, it was normal. Have any other 3.6 drivers ever had this happen?

I have a '03 V6 3.5 Santa Fe. The clutch on the AC compressor went out and was making a loud racket. When I was pulling the compressor off I noticed the wire harness connection to the compressor was damaged. Either by me or previous change.
So the end of the harness on the car side is damaged. Can a new one be purchased and spliced? I cannot see where it goes to see if it can be replaced.

My car is making almost like a clunking sound when starting. It doesn't do it all the time, mostly it is when its a cold start but its happening more frequent. I have the push button start, would warranty cover this?

New to the prius world! I recently purchased a 06 prius with 185k. Gas engine needed to be replaced so I recently replaced it. Had code of engine failed to start. Now got replacement engine in and has p0300 and p0303 and p0304. Weird thing is new plugs. Swapped coils and injectors with same results. To me it sounds like a racket in the transmission. The noise is not consistent at all. Very loud and odd. Also inside the car when I put it in drive or neutral a warning light comes up and says shift to park batteries wont charge while in neutral.

I have a 2006 Mazda 6 that ive owned for a year now. It has this random problem tho.... when accelerating into 4th gear it makes a horrendous racket like the bottom is falling out of the car or something and sorta jerks. it has been doing this a long time. other than that it drives fine! i have no mechanical knowledge about cars so im totally clueless! this seems to happen when accelerating on an incline.

So I finally went and put the exhaust I had been wanting on my truck. Pretty simple set-up. I had the factory muffler cut off and a flowmaster 40 series on it previously. I liked the sound under load and at cold start but normal driving I could not tell a difference from a factory muffler. So I had the flowmaster removed. I still have 4 cats so it's not crazy but it is loud. The only time I have cackle is on initial start-up not even at WOT which was a pleasant surprise. I just like the look of a single exhaust but still want some sound. I have been gone awhile as I needed a little break from starting and also being drawn in to arguments.

I have a 2002 camry 4 cyl. I bought at 65,000 miles. I drove it for 2 years and had a clanging sound that would come and go. My timing chain needed replaced because the sludge in the bottom of the pan clogged up the tube taking the oil to the chain. I religiously changed the oil every 3,000 miles, but I still get sludge. Is this an engine that was recalled by Toyota?

So I had been noticing a bit of wheel hop in third gear before my UM flash. Just got the flash a few days ago, and I love it. But since then two things have arisen:
- When sitting at idle, the car vibrates. I can feel it through the brake/gas pedals and steering wheel. I didn't notice it prior to the UM tune. It's like an undulating feeling even more than a vibration.
- When upshifting, I now seem to get a clanging sound/feeling if I upshift anywhere less than about 3200 RPMs. It doesn't always happen, and it won't happen if I'm really fast with engaging the clutch after taking my foot off the gas. But it is disconcerting.
Prior to the tune, I had gotten used to the sort of bucking and whatnot when you let off the gas and learned how to shift to minimize it. But now it isn't as easy to do a mellow, smooth upshift under 3000 RPM's...i.e. if I just want to pull away slowly from a stop. My question is, do these sound like symptoms of bad motor mounts? The car has just under 25k miles on it. The mounts are all stock. I was wondering if the UM tune was just enough extra power to put one or more of them over the edge.

I have an 02 mercury mountaineer awd. It's making a clunking/clanging sound when going in forward and reverse and it gets louder when turning. Just replaced driver cv axle, changed fluids on front and rear differential also put the stiction modifier in rear. It only does it on the ground assuming it's putting a load on it. Won't do it on a lift. What might be causing it. Tires are same size also.

My air con is not working, it started making an oscillating sound and not getting cold, which I think is the compressor. Garage couldn't find any leaks using a dye. So I asked my mechanic to change it. The generic part was a little over 300 but when he went to fit it it had the wrong number of mounting holes. Think he said it had three instead of the four from the original part? So he was not sure it was a suitable part, so didn't fit it. Because in the UK the CM model started selling in 2006 not 2007 it's possible he got confused and got a part for the older model? The car is definitely a CM!

My 2008 Camry V6 has a noise that happens when I first start driving forward right after the transmission shifts from 1st to 2nd gear, from inside the car it sounds like it's coming from the engine compartment on the driver side. I've figured out that the noise happens only when the engine is completely cooled down and it happens only once until the engine is cooled down again. It doesn't do it when in reverse, however if I reverse first it will still occur when I start pulling forward and the transmission shifts.
I brought my car into the Toyota dealer and they say that they don't hear anything wrong. They ended up replacing an axle because a boot was torn so I was hoping that it would end up fixing the issue but it made the noise right away when I picked up the car.
I have a video of the noise happening... turn your sound up and you'll hear it right at the 0:14 second mark of the video: [URL] ....
I have literally 89 miles left on my extended warranty so I really need to get this fixed. Back to Toyota...

It only happens on a very Rare occasion.
When Cold, and when I start out as I open the throttle, it suddenly sounds like there is not a piece of quieting stuff on the engine. I mean its like I can hear right into the engine itself.
I back off, It goes away then I dont hear it again for another Month or two.

My Jeep makes a whining noise and sounds like a diesel truck. In the morning when I back out of my garage and reverse down a little way the noise is there. When I then drive off, the noise gets even louder. As I drive, the diesel noise seems to stop. The whining noise fluctuates. The whining noise started when my mechanic put in a new tensioner. He insists that the problem is the compressor. Twice he has removed the belt and checked everything and he says there is nothing wrong with the car except the compressor. T he air conditioner mechanic says it is not because the ac works well. He said that he has seen quite a few Patriots with this problem but he cannot tell me what it is because the people never come back to tell him what the problem was. I play the cd and the radio loud to drown out the noise so my husband who had a stroke does not have to listen to the noise.

I was wondering because serpentine belt is a big thing for 05 corolla since everything runs on it. I also had a 94 camry which had a alternator connected to a belt. and if i wanted to tighten up that belt i would just loosen the alternator and pull it. Is there a way to tighten up serpentine belt in my 05 corolla in the same way?.

Is it possible for the brakes to make some kind of noise when it's cold outside?
I've been noticing some kind of noise after a cold start, I'd drive the car a little bit then apply the brakes and it would just make this random noise coming from the front-right side of the car. It sounds like a grinding noise, but I can't really tell. It doesn't create an issue either, I'll let go of the steering wheel and the car doesn't drift in any direction at all, the noise appears but the car is slowing down properly.
The noise disappears though after the 1st time it happens, and would only reappear after you've turned the car off, parked it where it's cold and it would only appear after not using it for at least 2 hours. My dad already took it to the dealership and they said the brakes are perfectly fine.

My car has been making this sound for such a long time i didnt notice it until my dad asked the dealer about it and they said 'they didnt hear it' i can get an audio clip if you think it' work. most regular steering around curves, just tight slow turning like into or out of a parking spot. it sounds like its right in the column...

I purchased back in January my 2013 Passat and today for the first time, I noticed that when I turn my steering when the car is not moving, I hear a clunking sound and I can actually feel the clunk too.
When I'm driving I don't feel or hear anything. It's really when the car is on but not moving.
This is getting annoying because this is the 3rd time something is going wrong with my car.
Going back to the clunking, I was reading that it's a common problem with most VW vehicles.
What it could be. I don't wanna look like an idiot that's been going to the dealer so often for these types of issues.

Ok, here another brain buster that I cant let go a minute longer(i'll explain later). I just got back inside from replacing the starter in my 02'' VW Jetta tdi. The starter is for a 97" VW passat TDI manual. A little over a year ago, I had my auto transmission swapped with a manual passat so its the right starter. Regardless, i just replaced the starter and and upon start up the starter is making a WWW ZZZing sound after start up.
I've been down this road before, its partially the reason for the swap in transmission. About three years back i replaced a starter on the original trans and this familiar sound was present after start up. During the course of a year i went thru 3 starters and and they eventually ate my fly wheel. By that time the trans was starting to grind when it downshifts from 2nd to 1st. not all; three four replacement starter made this sound.

I've got a noise that I just can't find. Have replaced a bunch of stuff trying to eliminate this sound.. steering pump, both front wheel bearings, new pads up front, both caliper brackets and pins. Did a new turbo, verified the new pump is not air bound, brakes work, no noise with wheels up, lock to lock, pumping brakes the whole time.
Sound is prominent at 1400 RPM, does go up with RPM, seems sometimes to follow a steer to the right. When I shut down, not at full temp a clunk happens, like a mechanical stop. That clunk is less noticed once up to temp and it really started after the steering pump. Sparky came over, listened with a probe, says it's not the pump, my BIL and a close friend say the same thing.
Today, when I nailed it, rpm came on hard, tires smoked and when I let off quick, truck died, like something held the belt. It just slowed and died, restarted immediately.
Shawn listened to the transmission, says he heard nothing there either but did hear something above that near the back of the motor.
IPR is spot on 21.8%, ICPV is .80-.82 and [email protected] However, it has been dropping to lower numbers recently, saw 15.4% and it often sits near 19.4%-20.4% for periods of time. Tap the throttle, right back to 21.8%.
I'm at a loss. I've tested everything I can think of. I can power brake the truck, no trans slippage, it spins the tires easily around 10lbs boost. The A/C seems low on the charge, it is freezing the dehydrator and I added some freon, 18oz can, the clutch is not frozen. Turn it off, compressor stops spinning like it's supposed to. The tensioners are not frozen or squealing, water pump is not making noise, temp is 200 on the dot. Trans is full, no burned smell. Motor oil is fresh, filters clean.
It sounds like a grinding noise and I'm about to tear the cover off the HPOP. I'm at 150k now and know it will need replaced soon, I've spent $2500 in the last 2 weeks, but before I tear it apart......
