Passat (B6) :: Clunk Noise Randomly While Driving

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?

Additional info:

2008 Passat Komfort High Def
2.0t TSI w/ APR stage 1 software, stage 2 intake, and future 3'' exhaust next week from APR

Car feels and responds great, no damage outside and nothing dragging. i really am at a loss.

Camry :: 2003 V6 - Trans Makes A Very Noticeable Downshift Clunk On Stop

I have a 2003 Camry LE with 1MZ engine and U151 5 speed auto trans. 138,000 miles The problem is that the trans makes a very noticeable downshift clunk when stopping.

With light driving you can feel what seems to be a 2-1 downshift just before stopping. With aggressive driving and rapid stop the clunk is felt either when stopping or actually after the wheels stop turning depending on speed and hard braking. If you stop aggressively it actually feels like someone hit you from behind. It literally shakes the car.

TRANS FLUID is full and clean. There is no smell or burnt appearance. The trans tests good in forward and reverse stall tests. Neutral to drive/reverse engagement is also quick and firm.

Here is the fun part. The condition does not exist when cold. After the engine and trans warms up it starts happening. Also, after presenting the condition with a hot trans, I can shift it out of drive and into 3rd and have no problem at all no matter how I drive. To make things more interesting, I can erase the trans learned values with a scan tool and the trans shifts normally for a couple of days before the condition returns.

We are concerned that there may be damage done if this condition continues.

IS F (2008-2014) :: Front Wheel Hubs Makes Clunk Noise

So from my previous post of might having a tranny problem or differential issue, it turns out that my front passenger side wheel hub is bad. Here is the odd part......the front passenger side wheel has some side to side play and it does make a clunk noise but it spins freely. On the driver side, there doesn't seem to be any play but it has resistance when spinning the wheels. Are both front wheel hubs bad or just one?

Golf/GTI VII :: Front Suspension Makes Cranking Noise Randomly

I notice it mainly when leaving my house. Might I add I live on a dirt road that this car is not made for, so I often go about 5mph until I hit the pavement. When I back out of my driveway and cut the wheel rather sharp, there is a creaking noise from the front end. When I hit the end of my dirt road there's a hump in the transition from dirt to asphalt that's not quite big enough to bottom out but I'm sure it stretches out the suspension. I also here some creaking noises sometimes when I'm turning into the road.

Other than that, I can't say I've noticed any noise while driving on crappy PA roads. Now call me silly for this, but I've never checked for the strut pucks as I have no belief that they are still there. Just based on from what I have read, my car doesn't feel like I'm bottoming out over every little bump, so I don't believe that is the issue either.

Sonata NF (2006-10) :: 2009 - Pop Or Clunk When Braking

I get a pop or a clunk from the front drivers side when I brake. It used to happen less often but I took it to the dealer to fix and they lubricated the caliper pins and now it happens frequently. I've read that the Sonata has some issues with the calipers. I would like to repair it and lubing the calipers made it worse.

Lexus LS 2007+ :: Clunk When Braking In The Rain

This problem is recent and only happens when it rains. When braking to a stop, I get a thunk or two. I only having hearing in one ear, so where the sound might be coming from. I ruled out loose things knocking around. The last time I was driving in the ran, I got the thunking only the first one or two times I braked, and then nothing. Other times I have gotten it repeatedly in a single drive. I have never gotten it while braking except when coming to a stop. I don't get it when merely slowing down in traffic or the freeway. I back into my driveway and I am wondering if braking in reverse has any bearing on this problem.

I searched here and on the internet. The problem exists out there as I have described it, but no posts that I can find have identified the problem. The truck has disc fronts and drum rears. I took the front tire off on the drivers side when I re-seated the front wheel bearings. I was going to repack them, but didn't feel like pulling the caliper, so I just re-seated them. I repacked them not that long ago and didn't feel it was worth the trouble at the time. I didn't bother to pull the tire on the passengers side. While I was at it, I greased all the ball joints.

I can't recall exactly when I first started hearing the clunking, if it was before or after the whole U-joint/carrier bearing campaign, but I became acutely aware of it afterwards, perhaps because that's when we got a lot of rain. There is absolutely no driveability issues at all, just the clunk when braking to a stop in the rain.

Subaru - Legacy :: Single Clunk When Braking

I have a 2000 Subaru Legacy with just over 215,000 on it. The car runs nice and I just replaced the plugs and wires as well as the transmission fluid. There is just one other clunk and I don't really know what it is. When I brake there is a clunk that sounds like it's coming from the back somewhere near the center of the car. It is a single clunk. It doesn't seem to affect how the car brakes or handles but I want to know what it is.

Touareg :: Single Clunk When Braking While In Reverse

I get an audible 'clunk' whenever I brake while in reverse. The sound reminds me of my old 4X4 when I would back up to take it out of 4 wheel drive. I searched for some existing posts but didn't get the keywords right or they don't exist.

Lexus GX 2004-09 :: Clunk / Thud Noise When Braking Or Accelerating

My 2007 GX470 is making a clunk/thud noise when braking (more often when braking hard or on a downhill slope) and then again when I let off the brakes and start to accelerate. It is significant enough that I can feel the car jerk some when it happens, almost as if someone has tapped the back with their car. What it could be?

Ford - Taurus :: Rhythmic Clunk From Rear When Slow Down / Braking

Our 2005 Ford Taurus makes a rhythmic clunk from the rear when you slow down. The rhythm seems to slow as you brake. The noise isn't there when you are cruising or accelerating, only when you slow down. We recently drove 2000 miles with a small trailer attached. Could that have anything to do with it?
