I have a 06 passat v6 with 34,5000 miles and with extended warranty,the car consumes about 14 mpg city and I noticed a humming noise coming from the back seat or bellow the trunk I am positive is the fuel pump, I will like to know if my poor mileage is related to the humming noise or should I take it to the dealer to have replace under warranty...
View 2 RepliesOur recently purchased '04 V8 Touareg is increasingly sounding like a jet turbine engine upon start-up, and especially as winter approaches. We're told it is probably the DC-powered fuel pump. Any way to reduce the aural effect?
View 12 RepliesIs it normal in these vans to here the fuel pump humming? I hear it when I turn the key on and while I am driving. It never gets quiet.
View 3 RepliesOur 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.
View 6 RepliesI worked with my buddy troubleshoot and remove a faulty fuel pump. He received it a week or so later and did the install himself. After this, he states that while pumping gas at the gas station the nozzle no longer cuts off automatically when full causing overflow. He says this has happened at different stations and different pumps. I told him to go double check connections and that everything was sealed. I am wondering what could be causing it..

I just recently bought a 2011 powerstroke f250 and while running I can hear the fuel pump humming pretty loud. Is this a possibility that it's going out? Or is this normal?
View 3 RepliesI just traded in my base 2dr 2013 golf 5spd, for a 2013 Passat 2.5 auto. (crazy good deals on right now in Canada! only 45 bucks a month more )
Any way, I have two noises that probably should not be there,,, one is a whistle chirpy noise from the front sounds like a bird trying to get internet dialup...thinking secondary air pump, however..does change pitch when turning wheels.... and dies down a little when warmed up... but liveable for now..
Fuel pump, it resonates in your head!! It must be stopped... Is this common for all B7 Passats? High pitched annoyance just kills that new car feeling... I am only at 600 kilometers. its only heard when the radio is off but still slightly heard while driving.
I read filling the tank up with gas might work....but no not even a little. I'm thinking a trip to the dealer to replace the pump... if that doesn't work will dynamat solve the problem?
This has happened twice so far, both with around 1/2 tank. After driving for ~25 minutes to work, I will go to shut the car off, and after pushing the key in and pulling it out, there is a mechanical noise from the rear of the car that lasts for about 2 full seconds. Is this the sound of the fuel pump on its way out? Or just an electrical gremlin (no! not in a VW!)?
View 7 RepliesOk, wifey went to pull out of garage the other day (Tues.) and after putting car in gear, boom it went dead. She started it again and after 2 seconds of sputtering boom dead again. Tried it when I got home and spun over fine, but no fire. screamed fuel pump to me, but I did all the little things first, Fuses #7 and #26 or 28 or something like that, both were good. So I proceeded to check voltage at the pump (It is NOT under the back seat as alot of people told me..) it is under the passengers side mat in the back.
I checked the voltages when my wife was cranking the engine and it was 12.5 volts. When the key is just "on" the volts were 3.5... I went ahead and pulled the pump, not hard - just I had never done it / pumped 12 gallons of gas out.... Tested the pump connected straight to a battery with jumpers (6'+), and nada the pump didn't do any thing. reversed the polarity and it clicked, reversed it again and clicked again, after the 4th time it went to buzzing. I put it back in and nada.
Pump would work sometimes when it was laying on its side. Good enough for me, new pump ordered. New pump installed and cranked it over, nada. Cranked it over again and sputter sputter - vrooooom! Yea! fixed. Well sorta... Read on. Car started up immediately after shutting it off when testing - turned car over to wifey (after flushing brakes and replacing front pads with those niffty green ones...)
OK here is the point to this diatribe: Car's fuel pump isn't firing with the switch "on". it is pumping when the key is switched to "start", and it runs when the car is started. So you have to crank the engine to "prime" the fuel rail. The second time you crank it, it fires right up. Car accelerates well after started but the double cranking cannot be good on the engine's starter. The fuel drain happens sometime after the car has sat for 15+ minutes. If you shut the car off, then wait up to 15 minutes (all I have had time to sit still and check) the car will fire right off. I just don't know what to check now. Could the relay be bad?
I do not hear any humming from the back when the door is opened. What triggers the pump when the door is opened the CCM? It didn't do this before the car quit, always started with a second or two of cranking...
Pump buzzing/humming noise varies depending upon whether accelerating, coasting, or decelerating. Sound is reminiscent of a dentist drilling my teeth. Is loudest while accelerating, hardly noticeable while coasting, and somewhat noisy decelerating. Had one suggestion that the FWD torque placed on the steering rack causes the different noises. Haven't been able to do anything to quiet it.
View 2 RepliesWhat is the solution to fix the secondary pump humming/vibration noise? I get this humming noise from my driver side center dash area and according to few other members, it's the secondary pump. Some dealer fixed it by moving it to the side a bit to stop the vibration.
My dealer told me that's false and it's normal to make that noise (never had this noise before) and if there is something wrong, VWoA will issue an TSB to fix it..
Well, they won't do anything until there is an TSB and I was wondering if it's a easy fix that i can do it myself??
I have a 2005 F-150 supercrew 4.6L with appx 127,000 miles on it. Back in December i took the family to a drive in movie and left the ignition turned to the on position. I jumped the battery and drove a few miles home. The next morning when i tried to start the truck it would not turn over. There was a buzzing noise coming from the fuel pump but not enough juice to turn the truck over. This has happened a few times in the last couple of months but will jump and run fine for weeks at a time. I've taken a 2500 mile round trip to Texas with no issues. I took a 200 mile trip this past weekend and now it will not start. I'm thinking it could be the fuel pump relay? I went to the parts store and bought a relay but it's not the same size as the one in my Haynes Manual. The part from the store is the same size as the bigger relays in the kick panel fuse box but does not match any of the plugs. According to my manual the fuel pump relay should be a smaller relay.
View 4 RepliesI bought the car( like six months ago) there has always been a loud humming noise from the fuel pump ( I'm pretty sure it is the fuel pump anyways) not the normal whirring noise the fuel pump makes but a hum you can hear about ten feet away. Had no issues till just lately when the afternoons are well into a hundred degrees. That is when my car starts giving me issues. After one of these hot days on my ride home from work, I had just come off the highway and stopped at a stop light when I felt the engine bogging out, the engine stalled and I had to push it to the side of the road.
Its worth mentioning that this humming noise is much louder in the heat than the cool morning then when I turned the key to hear the fuel pump(auto fuel inject) it was louder than it has ever been, and would keep stalling on the way home, I had at the most a quarter tank of gas (gas boy is busted/stuck I think) the fuel pump is bad? Could it be the sock? I thought I read somewhere that my girl pump uses gas to cool down, and that having the tank any less than a quarter could lead to the fuel pump overheating????
I recently noticed a humming noise coming from the passenger side on my Mazda Protege 2000 ES . I suspected it was the water pump, so I took the car to my mechanic. He inspected the coolant reservoir and it was empty. He also checked the noise and the area were the pump is, and told me that the water pump had to be replaced.
My dad told me that his 1994 Sentra had the water pump replaced but none of these things had to be done and that it was unnecessary. But then I thought, every car is different.
I was in shock with how much the repair would cost, so he then gave me another quote with just the timing belt and water pump replacement for $503, but this time he said that he will not give me any warranty for the repairs because of the tensioner.
This van has had a couple of fuel pumps, no surprise there, and i need to look through my paperwork and find out how many miles the current one has on it, but it has the STRANGEST habit I've ever had on any vehicle. Starts fine, runs fine, no fuel pump noise when van is running, and when you turn it off, the fuel pump creeks on and off for several minutes.
I mean a strange creaking noise almost like a shorted electrical device or a vehicle's brakes when you park it on a hill and the breaks creak as it settles into place. I'm probably doing a lousy job of describing this but i don't know how else to describe it!
ALSO, if you lay under the van and wait til it stops creaking, you can tap the bottom of the tank and it will creak for a few more seconds. You can tap repeatedly and make it creak more. Is it about to explode? Can i trust it on a road trip?
5.4 L, Engine runs if primed at the intake. Fuel pump can be heard running but no fuel gets to the engine. Truck is mint and being sold real cheap due to this issue.
Fuel Pump? Filter? Both? I haven't seen the truck, a friend is considering buying it and rolling the dice it is a quick fix. Fuel is in the tank .....
I am curious as to what are signs that a fuel pump is about to fail?
View 11 RepliesI just started getting a humming sound at 55+ mph coming from the front left side of the car. the pitch of the hum changes with the speed of the car and goes away as you slow down. i can't hear anything when i roll the window down because of the wind.
i plan to let it get worse until i take it to the dealer. they do not fix anything unsell it is totally broken.
How difficult is it to change the fuel pump module?
View 4 RepliesHad check engine light come on as the car stalled. Brought the 09 passat to vw dealer and was told the engine code showed fuel pump defect. For 1,000.00$ they changed the fuel pump and did a fuel system cleaning. Also had an oil change done.
Drove away less then 10miles, and the same thing happened. Bringing it back tomorrow, but how to handle the situation? Already contacted AMEX regarding the situation to potentially open a dispute charge claim.
If the MIL indicator is on, does it give a direct code to the problem? I suggested it could be the manifold issue, but they said that's not it.
My car (5spd b5) developed front humming noise. I have changed bearings, axles, and tires and it didn't work. I also checked the transmission oil level today and its normal and clean. The noise is not engine related and it depends on the speed only! starts at about 15mph and it gets worse as I go faster. At 60mph the noise is annoying. As the car becomes lighter going over a crest, the noise disappears and comes right back when weight is back on the wheels and suspension. All new front-end suspension, tires, bearings and axles and nothing seems to improve this.
