Passat (B7) :: 2012 - Fuel Sloshing Noise?
Dec 2, 2011
In my 2012 Passat TDI I get a pretty loud fuel sloshing noise from the back. The dealership confirmed the sound exists in other 2012 Passat TDIs as well. This sound is at it's loudest when the diesel tank is about 1/2 to 3/4 full; it makes loud thuds (diesel sloshing sounds).
The service manager says that is a design flaw and VW does not have a solution for it right now. He says may be if enough people complain they will come up with a solution.
Initially we thought this was AdBlue but it was confirmed as a fuel noise as the noise varies at dfferent levels of fuel in the tank.
I know I can crank up the radio and not hear the noise but I don't always want to do that. I am just bummed that there would be such a big oversite from VW on a car that is suppose to be their comeback in USA.
My car is a TDI 6 speed manual trans. Does the SEL owners also have this noise? Does the gas engine owners also have this noise?

When I stop the car, sloshing noise come from back of 2006 Toyota Camry after filling full tank of gas. Tried couple times, I can still hear the noise feels like liquid sloshing noise coming from fuel tank. Even after I parked the car, tried to push the back side of my 2006 Toyota Camry, sounds like the fuel is sloshing from the tank. Is it normal? I never heard about this before, maybe I didn't notice. It was not loud but audible.

I have a 2003 2.8 Passat. I replaced the timing belt and I am now hearing a noise that sounds like water sloshing slowly back and forth. I only hear it in the mornings when the car has been sitting over night. At first I thought it might be something like a little air left in the heater core. But after many days driving with the heater on full the problem is still there. The cooling systems works fine and I have hot air at the vents. It usually makes the noise during turns.

Hearing a sloshing scraping thumping sound coming from their 36 gallon tank under hard braking accelerating? It's loudest when the tank is between 200 and 150 miles to empty, I checked the spare tire and its tight, haven't had a chance to crawl under and look around yet though, I think something inside came loose. 2013 XLT.

I thought the air will be flushed out from the heater core over time. Heater works ok, but can hear a sloshing sound.
Does pressing the rubber heater hoses going to the firewall? Other methods? Take coolant tank cap off once in a while?

I have a 2001.5 Passat with the ATQ v6 and 5-sp manual tranny. A few weeks ago when I drove it up to Chicago, the heat completely stopped working. Cool air was coming out of the vents. Then when I drove back to Texas, the heater started working again. Now as of yesterday, the heater's out again. My temp sensor has the engine at 190 F, so I don't think it's overheating. One thing I do notice though is when I first start it and shift from first to second (or if I go over a speed bump), I will hear a water sloshing sound as if I'd hit a puddle. Whether it's the heater core that's blocked or perhaps the thermostat?

Having issue with water being trapped in the frame of the car?
Yes, I know, it sounds completely peculiar but it is driving my wife and I crazy. It sounds like there is a bucket of water sloshing around in our backseat. However, there is no water, not a single drop, anywhere around the car or inside or outside of the car. We had heavy rain Wednesday night so that could explain the source but I can't find the entry point or exit point of the water anywhere on the vehicle.
Whenever we accelerate or brake, I can hear water rushing forward or backward but can't locate where the noise is coming from. Nothing is wrong with the car but I can't imagine this is a good thing.

2012 Passat SE ... Where the fuel filter location is? I've changed the fuel filter on many other vehicles and know that it should bee right in front of the rear passenger tire..however I was looking for it to change it the other day and I could not find it. I loosened the plastic covering on the passenger side in the rear and didn't see the filter. Looking for a picture of Gas engine Passat that is 2012 or newer??

I started my Gen 4 Prius two yesterday and got out to adjust a bolt on the rear license plate and noticed a strange sound as the ICE in high throttle began the warm-up cycle- a sound like water sloshing around in the cat converter (or somewhere upstream?). Other new Gen 4 owners please check this and see if you hear this on startup. It is not regular enough a sound to be engine knocking, but literally like water churning. Not loud enough to hear from anywhere but right near the lower rear of the car. Hear this on new 2016? My Gen 3 never had this sound.

My 2011 Subaru Outback 3.6R (bought in Feb ’11, and has 4k miles) has already had several issues in its short life. In just the past week I've noticed a sloshing noise coming from the gas tank. I first heard the noise when I was backing out of my driveway. I also notice the sloshing sound whenever I go over a bump or come to a quick stop. To determine where exactly the noise was coming from, I parked the car, turned off the engine and I pushed on the rear bumper to make the car move up and down. After doing this I determined that the noise is definitely coming from the gas tank.
Is it normal to hear gas sloshing around in the gas tank when driving? Could there be something wrong with the gas tank?

Only had my 07 GS350 AWD for about a week now, and i kept hearing water sloshing around the floor boards. Did some searching on her and the interwebs and found the HVAC evaporator drain blockage TSB. So.... this was step one in getting it handled. I don't think its been wet for too long, only because there is zero musty smell or mildew. I yanked the front carpets back, and parked nose forward on my steep driveway, sopped up 5 full bath towels worth of water, cranked the heat and put fans on it. Boom, cleanup, done!

Live in Las Vegas, NV & brand new car is starting to make a sloshing sound when I brake. I honestly can't say if it's been doing it since I got it in June 2014, but hubby pointed out the noise to me just recently and now that's all I hear. I've tried stopping fast, coming to regular stops and everything in between type of stops and the noise can be heard every time. Could it be the gas I hear sloshing in the tank when I stop?

I had my gas tank replaced recently and upon replacing the tank, I now notice a sloshing sound when I stop my car. It sounds like I took a gallon milk jug and turned it over completely to pour everything out- glug glug glug. It seems to be coming from the fuel tank and the car rocks back and forth a lot. Also had work done on the struts at the same time. What is the cause of this and is it safe to operate? Is it reasonable to ask the mechanic to fix it? Is it possible that the wrong tank was put on my car? I've checked for information about this particular issue but have not seen any solution about this problem when it is resulting from a replaced part.

Okay, so I've been hearing this strange sloshing noise in my Jeep Liberty 2005. It happens when I start off from a stop and usually around 15mph. It seems to be coming from the front of the vehicle (engine). And I'm not the only one that has heard it so I'm not crazy.

Car is 2006 SWB 3.0 Tdi.
I've recently noticed a sloshing noise coming from the rear passenger door - I would estimate between 1 and 2 litres in there! I can't find any other post with these faults, so I've a couple of questions.
Firstly, I'm guessing the ingress is from the seals at the bottom of the window. I can't find a procedure to replace them...
Secondly, how to get the water out... It seems the water will be trapped in there - there's no natural way for the water to escape. If so, I'm tempted to drill a hole to let it escape.
Where would be best to drill the hole? Where water ingress is likely to accumulate?

I have been getting some noise from the fuel pump when the car is at idle. I am sure the noise is there when the car is moving but the road noise is cancelling it out. The noise is very subtle but a bit annoying. Do you hear your fuel pump at idle? I will take it in for a replacement.

I have a 2003 6.0l... When I first bought truck, seemed to run fine. Since then truck has broke down on me once. I took it on a six hour drive, and couldn't turn vehicle off, because if so, truck wouldn't start back up until cool. After getting to my destination, fans seemed very loud every time I pressed pedal, and seemed very sluggish. Drove it a couple days and boost was low and fans continued to sound like they werre engaging even when I first started truck for the day. Had truck towed to shop, because it cut off on me when driving.
At shop : Truck had air filter, water in fuel sensor, o-ring for draining plug, new ICP sensor and harness, and HFCM cleaned up as it was filled with gunk.
After shop : Fans quit being so loud, but have not had near the boost I had before issues started. Truck struggles to go from stop, and around 15 psi boost gauge starts shaking erratically. Also, I have been losing coolant in a short period of time, and can't see any leak coming from anywhere, and also my radiator has been making a sloshing/gurgling noise and it will stop, then come back all within bout ten seconds. And I guess while I'm writing, I should mention the bucking after it downshifts in about third or fourth gear giving it gas makes the truck buck until the RPMs are above 2000 or it upshifts or downshifts, and at an idle seems to miss until warm.

Our 2012 camry se had a problem with the fuel pump running when the engine was off. Several hours after we came home I went into the garage for something and heard a humming noise. First thought was a distant neighbor using a leaf blower, then realized it was coming from the rear of car. definitely coming from gas tank area. Turned key on, then off and noise was gone.

Passat (2012 3.6 SEL, 7500 mi) making a loud knock noise from the underside of the car. It happens, without fail, every time I pull it out of my garage, and often when I'm coming to a stop or pulling out of a parking spot, etc.
I have taken it to the dealer numerous times, only to have the "failed to replicate, operating as designed" on the service tag. The car has been in for so many other things, this is just another issue I mention to them every time. Since the other issues (aside from the rattles) have been fixed, I'll make this my primary concern...until something else wiggs out on the car.

I am new to VW. I just purchased 2 new cars on Monday of this week. A 2012 Jetta SE for my wife and a 2012 Passat SE for me. We are loving both of these cars.
I have a question though. If my car has been locked for a little while, I unlock the car, open the door, I hear a noise inside the car as if an electronic motor is running. It only last for a second or 2 and I can't pinpoint the noise. It almost sounds like the power seat is moving but I don't think that is it. Hears that noise when you are entering your car?
