Before you condemn the fuel pump check the fuel pump relay, my fuel pump just "failed" by having no sound while cranking but spun fine being manually triggered at the pump, it was only a $5 relay that saved me from a potentially $500 fuel pump job that most likely wouldn't have helped me at all.
Where is the fuel pump relay? Because my car starts fine but one day it started while driving felt like fuel gets cut off for a millisecond n after reapplying foot pressure it picks back up
2 x Passat B5.5 TDi's I have with 400k and 280k miles on the original pumps. Other family members have a Beetle and Golf TDI and both cars have had the pumps replaced twice.
I was helping a friend out for Passat fuel pump and Bring The tool to get the lower portion of the pump out and your video totally help. Although you did make it out look a lot easier. Lol thanks
What tool?
The reason the pumps sitting in a plastic housing is because there’s always fuel around the pump the gas tank is designed to centre the fuel around the pump. So when your tank gets low the fuel drops right to the pump. Some say don’t go below a quarter of a tank because the pump won’t be submerged anymore well yes the plastic housing won’t be under the gas anymore but the pump is still fine. Just never run the car completely empty cause then the pump will suck air and that will ruin it.
Hey man great video. I'm currently having a fuel pump related problem.I have 2010 VW cc 2.0 with 88 thousand miles. my car turns on just fine drives then dies when slowing down or at a stop. I'm just curious how I diagnose weather it's the high end or the low end pump.
Hey dude, I have a 2005 and 2007 Audi A6. I replaced the pump on the 2005, and a few weeks later, needed to replace the Fuel Pump Control Module. The recommended procedure is to undo a bunch of crap, (like exhaust?), and drop the tank a few inches. Took a few sources to find where to look exactly. I went a little bendy bendy on the floor instead, just enough to slide out module. I chiseled off the plastic bracket holding it. The replacement I retained with a screw and a nut. Bent things back and ensured a seal. "My God, Audi, why!?". Anyhoo, I'd love to see some content on modules, maybe testing. BTW, I did use my power probe to run the pump. Awesome little tool!.
Here is an issue I have been having occasionally with my 2012 Jetta 2.5L, 160k miles. A few times a week, [I noticed it more when it was colder and had the original battery] it would turn over 6, 7 or 8 times before the engine would fire. It was vigorous and didnt sound like a weak battery. After replacing the battery in May, this might happen once or twice a week. It also has been much warmer in PA in May and June. Winter really held on until April. I had this cranking issue in the winter of 16-17 and thought I would've needed a new battery a year ago but the issue seemed to have subsided and of course I put it off. What are your thoughts? Sensors? Starter? Bad ground? Loose wires? Your help is very much appreciated and your videos are priceless!! Thank you for helping educate me on VWs & all of your endeavors.
funny i stumble upon this as my VW sits in the shop, getting a new fuel pump (:
good video. SUB
Lol oh no!
google listens through phone and computer mic and advertises accordingly.
@@MyNeowolf huh, really??? no wonder i keep getting all these butt plug advertisements.
For Jetta MK6 (TDI 1.6), What should be the current (amps) of the tank pump when working ? i see in the manual should be between 4-8 Amps, but my pump amps is only 2.5Amps
My car run ok but my HPFP (siemens) failed twice in short period.
Btw, it's a brand new pump (Bosch)
Thanks so much for this video. So informative. I had a strange occurrence recently with my '99 Golf. On the way to an errand, some random, intermittent cutting out of power. When I returned 15 minutes later the car would crank but not turn over. About 2 sec into the cranking I'd hear a subtle thump from the general location of the fuel pump. I left it alone for about 10 minutes, tried again and it started right up. No cutting out signs on the drive home. I replaced the fuel pump relay. Only very small signs of those symptoms since. Do you think that thump I mentioned is a sure sign of a failing fuel pump?
Good info. Helped me narrow down issues. But getting parts are harder than I thought.
Where might I be able to get genuine parts for a scirocco mk3?
Hey Charles! Love all the content mate and I have a question may I ask? I've a 97 VR6 Golf and I bought complete bosh pump unit with the lines and I'm struggling to remove the old lines from the sender unit. Any advice on how to get them off please? Twist n pull only twists the lines and too tight of space for pliers. I don't want to be too rough incase I break the float mechanism that's attached. Nuff DUB love from the UK 👊🙌💜 Thank you
Edit: Solved it with boiling water in 5 minutes after writing this 🙈😂😂
I’m getting positive fuel trims while accelerating and then returning slightly positive at idle. Also some hesitation and inconsistent throttle. NO CEL
Fuel rail pressure is staying high so I think HPFP is fine! Car starts normal...
Could the LPFP be the culprit? Custom tuned stage 2 GTI, 145k miles!
Thanks for this video.
Wanted to know. On a 2014 VW Polo Comfortline (Indian Version), one of the symptoms I'm facing is a high pitched noise as soon as the engine starts. Also there is a bit of juddering/ jerking while accelerating. Could this also be a symptom of a bad fuel pump?
Thanks.
Hi there HumbleMechanic I own a 2013 VW jetta 1.4 tsi CAVD engine, the car had been acting strange for the past 6 months or so cold starts will cause it to vibrate badly but when the rpm stabilizes at 730-ish the vibration goes away and car runs smoothly doing a scan using OBD11 picks up misfires on Cyc 1&4 but not enough to throw a check engine light so I replaced the spark plugs by myself during movement control order after which the car ran smoothly though OBD11 were still picking up misfires.
Managed to get it to the garage after 4 months back they found 2 coil connectors were broken that was replaced they also performed scans which didnt pickup any misfires they also ran a compression test twice and results were perfect. At this point I thought the problem was fixed but after 2 weeks found that my fuel consumption had deteriorated a little so I ran OBD11 again only to find out there were misfires but no fault codes or CEL baffled by this I got it back to the garage this time injector test were done along decarbonizing (walnut Blasting) too and still there were misfires at this point I thought it could be my cheap OBD11 I wasn't accurate and so left it.
Just a week ago while I was driving home car started shuddering like it was going to stall car went into limp mode so I drove it slowly back home check engine light flashed about 3 times then went off but the EPC light stayed on used the OBD11 and faults registered were P0300. P0301 and P0304. Engine misfiring on cyc 1 & 4. Tow it back to the garage and they recommend changing coil packs which solve that problem. However the cold start vibrations still occur and when the car idles you can feel an intermittent vibration from under the seat.
This time after 3 days of testing in the garage they recommend changing the engine at 6k without a concrete reason. I brought the car home still runs smoothly except when it idles and cold starts vibration. I had done some searching up on google and youtube found a VW golf mk7 having identical issues which turned out to be high pressure fuel pump for the owner could the same apply to mine? would really appreciate any advise thanks
I’m looking for info on the tandem pump, I’ve gravity fed one, have a vacuum on the return, can’t get any flow through the pump, cranking or not. Can the tandem pumps fail like this.
I bought a 2003 VW Eurovan, drove it to the beach the first time. On the way over it was fine, on the way back though, I had the van die on me on the highway. After letting is sit for a bit, was able to drive it off the freeway then dies again. I was able to do this multiple times to get closer to home, but the van eventually would "live" shorter and shorter between these cycles to eventually having to park it to tow back home.
2016 Jetta Hybrid SEL less than 100k had a fuel pump failure. I was able to order a replacement and changed it out in about 2 hours, very easy. The hardest part was the top outlet fuel fitting that didn't have a button to press like the other fitting, it was much smaller clip that I had to push and it finally came off. There was another fuel fitting in the tank that attached at the bottom of the fuel pump housing, I guess there's another pickup point in the tank? Also the EPC and CEL lights were on, the codes were - P064A, P0087 (fuel pressure system too low), P2414 (o2 sensor sample error bank 1 sensor 1), P2279 (intake air system leak). Once all codes cleared the lights went away and the Hybrid drive started working. I also changed out the air filter and the cabin filter. That leak in the air system is another hose that I couln't get (it's back ordered).
I’m having an issue with my 2008 gti for the past 2 days when i put the ignition to the on position the sound of the fuel pump is different than usual and today i started having a weird hasitation between 5500-6000 rpm when i’m going full throttle, but before and after that spot the car runs and pulls normally, could it be the fuel pump?
I’m planning to take it to the shop tomorrow but i’m just scooping around for info for now
I also forgot to mention that sometimes it take a little longer to start, other times it starts normally and it does it randomly
Thanks for the video, I have polo classic 1.4 engine model 1998, the problem is it over fueling and cause wet spark plug and no start. What can be the cause?
Hi, I have a 2004 Touareg 3.2L v6. When I start the engine it turns off within 10-15 seconds. Once it got it fixed itself and started to run normal. I asked a shop to test fuel pressure, he it said its within specs. Same day I went to get gas and right after I got gas, same thing started to happen. Vehicle start to vibrate, gas paddle lose power, and turns off the engine. Do you think its the fuel pumps?
Rajeendra Lakruwan mine does the same mk5 golf 2004
The fuel pump won’t stop wining after the engine is turned off
And finally the car won’t start
It will start for almost a 3 seconds the shuts off
Hi All
I have a MK5 Golf R32. Fuel gauge works intermittently. Car drives fine. When I start up the fuel gauge will work and show how much fuel is in the tank, after a few minutes of idling, it goes down to empty.
Fuel in the car is about 3 quarters full
Is the fuel sender the issue?... any comments of advice would be appreciated. Thanks
Hey Charles, have you heard of a fuel pump buzzing while the vehicle is on? (2006 Rabbit) It's the same buzzing I get when I flip the ignition on. It's a feint noise and the runs just fine. Is this normal? The car has 134,000 miles. Thanks
Hi Charles i have a question for you , i have a 2012 passat this morning i tried to start it and it only cranks but no start , I’m a do it yourself guy , i open the supply line under the car and try a start , and have a good gas flow , but not going to the fuel rail , my question is , is there any valve between line after the fuel pump? Or there’s a blockage?thanks I’m waiting for your reply.
If the lift pump goes bad, will it throw a engine light? How can I diagnose with a VCDS? THX
Hi long shot but I have a Mk5 golf TDI 105 it's cutting out after running a while but before that I get a shudder but won't start back up unless I put some carb cleaner in the intake I have had the g28 sensor replaced also had the car plugged in and the only fault was glow plugs I live in the UK a recovery bloke said that's not a problem and help or advice would be brilliant the AA bloke said like the car has air in the lines
Hello mate I need a new fuel pump and was just about to order one however noticed there is a 3 bar pressure pump and a 4 bar pressure pump is there any difference to how my vehicle(2.3 V5 mk4 Golf) would run?
Yep...here I am.2005 A3 fuel pump gone 120k miles so not too bad..
Cheers bud!
I know I’m 8 years late. 2010 VW CC. 2 years ago the cabin in my car started smelling a lot like gas so they replaced the fuel pump. Forward to this week, it started smelling like gas again. Should I replace it again? This time I’m thinking of doing it myself
If I'm replacing the fuel pump can I reuse the straw from the old one or do I have to purchase a new straw, same with a module can I use the same one or do I have to replace it as well?
Question, I have MK6 TDI fixed gold 2.0. Sometimes when I am maintanin speed ~40 or so, third gear I get like a miss fire jerking action. I have a manual transmission. Is believe there is a lift pump to the HPFP and the fuel filter has been recently changed. I also think I hear the lift pump after shutdown. Its a motor on for two seconds of for two seconds on for one. Love your channel. Thanks in advance for your help. In addition most of the time the first start of the day takes 4 seconds, 3 times longer then starts the rest of the day.
Charles i replaced the fuel pump on my b5.5 passat and now in the morning it takes forever to crank over. Once i stop, crank again fires right up. Runs smooth no problems. Any suggestions? I only replaced the electric fuel pump
Did you ever solve this? I am experiencing the same problem.
so my audi a4 b8 keeps saying tank system malfunction contact workshop. and the fuel guage would go to 0. recently instead of saying that it keeps saying refuel and i have 0 gas left even though i just put gas. The pump seems fine im assuming the sender unit is faulty. Can you buy it seperatly and then attach it to the old pump? also its a quattro is there only 1 sender unit or is there two each side of the saddle?
2008 Passat tdi 2L engine stalls and the engine fault light comes up while driving and the car slows down. Done that, advised to change the Manifold - done that. The car runs great until the engine fault light comes up. Does the fault lie with the fuel pump or high pressure fuel pump?
Hi, have you done a video about the newer three phase in tank pumps ? cheers
Hello, I was wondering if I could run an in-line file pump to bypass the current in-tank pump? Would I have to detach the existing wires that lead to the in-tank pump and attach them to the new in-line pump? Help would be much appreciated.
you could do that, I don't know how well the inline pump would be able to pull the fuel out of the tank. You could also use the wiring for the OEM pump most likeky,
The reason why I think there is a problem, I’ll be sitting at idle, and every couple of seconds the engine will hiccup and act like a stutter and at low end if I press pedal, engine light comes on and it’s a little boggy, but if I slam on the gas pedal it will down shift normally and shift properly, it’s just under small load that it hiccups. Any idea? Help would be so so so so so appreciated.
HumbleMechanic I figured it out! It was my coil pack and spark plug wires. Lol
Hey man,i have a 2013 golf 7 1.4 tsi dsg and did a dino on it and the power output is way lower then the factory power they said i need to open my fual pump and clean the strainer or something like that, what would you suggest
to lift the pump and clean the strainer, lol :) that's the prefilter thingy on the bottom intake of the pump
Please answer if you know,
Would golf mk4 2000 in tank fuel pump fit to mk5 2006?
Both diesel,
Excellent commentary.
2018 VW Tiguan Engine stalls while driving. Almost daily. Takes multiple restarts for engine to start.
Thanks, I would like you to know I really appreciate your narrow focus on the VW brand. Yes I am a little biased since I have two of em. Rock on man. ;)
Iam D Thanks!
Do the fuel pump tend to go bad
000⁰⁰
Great video and thanks for sharing. I'm new to the volkswagen family and I am pretty an amateur when it comes to car issues. I bought a vw passat b5 1998 model 1.8l petrol at a government auction. It's driving perfectly well but with notable problems. The fuel gauge is not working, gladly the fuses are OK and the pump is still working but no longer in its perfect state because it drags to start especially early morning hours. Maybe it's another problem not related to the pump. Secondly, the central control unit burnt-out because of water. I've ordered a replacement. What should I do with the gauge. Secondly, what do I need to do when replacing the central body module.
Hi mate would you know where the location for vw sharan fuel tank pump would be I’ve tried finding a video or diagram online nothing I have issue with starting the car and been told to change the fuel pump thanks
If the fuel module is bad can it cause the fuel pump to go bad? Dealing with problems with my 2015 Passat volkswagen thought it was the fuel pump replaced that for $900 and now are trying to say it’s the fuel module which is another $400 to replace
Hello, I have a Seat Ibiza 6J Sport Coupe from 2011. It is a 1.2TDI 75 horsepower. My car drives but my fuel pump is very annoying. Its like a bee is flying in my car. How can I stop that annoying buzzz sound? I can also not find any fuel pumps for my car, only originel and that is 400€...
Hello guys,
Thanks @humblemechanic for the vid
I have this error codes :
P310b low pressure fuel regulation
P3089 electronic fuel pump, signal cable electric fault
I changed the HP Pressure fuel pump last month.
The car starts and drive fine but don't go over 2900rpm.
I recently got a blown fuse related to the tank pump replaced it than after 2 weeks blown again.
How do I know if it is the pump or the relay above it.
And does it relate to the error codes?
Any help is appreciated!
Does anyone have any thoughts B7 (Passat) fuel pump life expectancy? My daughter is moving far away and don’t want her to get stranded. The car has 125k and is original. I have about two weeks and thinking of proactively changing it before she leaves. If there is anything else that is a “must do” if original please let me know (PVC oil separator) is on my list. The car has had great maintenance and does not leak or burn a drop of oil. The water pump might be original but bone dry. Thanks.
I need help my volkswagen cc 2012 doesn't start.. it cranks but doesn't turn on . I've recently changed my transmission clutch . Took it apart and put everything back and now it doesn't start ..it started before I changed the clutch. Things that I've done are , I changed the high pressure regulator fuel pump thinking that was the issue and I tried starting it and nothing .. I've also checked the spark plugs electrical lines to see if it was a power related issued and they all seem to be good . I've also replaced my battery thinking it was that and still no start.. now I don't know what to do or what to check for and tips ? Keep in mind that this is my first time doing this sort of job .
I have a problem with my 4.2 treg that may stump you. Would LOVE to see if you could help me. VW dealer in Atlanta turned me away last week bc they didn’t have a tech good enough to work on the Gen 1 Touareg. Hope you see this and don’t mind if I can pick your brain on what to Do next.
If the pump makes a "crrrrr..." noise when it's low on fuel and it takes about 2 or 3 switches of the car key on and off to disappear, is it time to get a new one ? When the tank is full or half-full, I can't hear it, I guess it's already primed, being sunk in fuel.
How's vika dpa as a replacement part for Intank fuel pump? Any other reputed oem players?
Crisis with sourcing vw oe parts in India
Great video! My lady has a 2014 Jetta s sedan. It’s not starting. It’s getting spark. I checked fuel pump fuse and it’s good. I disconnected fuel pump and ran multimeter in ohms on the pump itself and it gets 0.02 resistance. I’m assuming the pumps bad. Do you happen to know exactly where the fuel pump relay is on this car I cannot find a solid answer any where online thank you!!
I have a 2006 2.5l Jetta with 155k miles on it.. And I notice at times when the tank is a 1/4 to 1/2 full I can hear a beeping noise(like the timer on a bomb)coming from the trunk on the right side. As well as a knocking sound as if someone is locked in the trunk and trying to escape from the right side. Both sounds do stop after a few minutes, but it seems to happen if I haven't driven it in a few days. Another thing that happens is, when I fill the tank up it won't start right away, it will kill. I would have to pump the gas pedal while not on a few times then crank it. But in order for it to stay on I have to idle it for a couple of seconds, after that it runs fine. I also replaced the MAF sensor, air filter, and valve cover because I got a code P2279 and it was stalling & jerking. So I don't know if it's the fuel filter or fuel pump that's causing this issue.
Great video, so I have a big doubt, do you know how to calibrate the fuel gauge in MK4's VW? I've a VW Polo 2003, I'm from Mexico and I changed the fuel pump but the fuel gauge doesn't work, when I start the car, it shows fuel tank (even if the tank is low) the gauge only gets down when I turn off the car. Ir you can help me, I'll be really greatful!!
What was the response to this question? It's also my problem
I need your help.i have a 2009 VW tiguan 2.0TSI CAW.my fuel consumption has been very high I was advised to check for the tank ventilator that allows excess fuel to return to the tank has been blocked.i have checked online but I dont see this part.maybe it has a different name
I have a bit of extend crank on my b6 2.0 tsi, could be pump?
I had to change the FP on wife's Accord. Simmilar design. meant to be changed as a whole unit. bought an aftermarket performance pump for the car, Diameter was the same, but was longer 2 centimeters. Being carefull, the upper part came off from the bucket. Had to modify the pump bottom seating, with a hack saw and knife, to fit the filter.
i do not know the VW but on the accord, the return line come to the bottom of that bucket and raises the fuel level arround the pump to cool it. So when the pump gets fuel, then it will be cooled too.
I think that the pump/sender unit is changed as an unit in all car makers, The pump changing is for the DIY and independent shops.
Hello mate, i can hear a loud clicking noise coming from the fuel pump when is on idling only. When i press the gas pedal the noise goes away! I lift the rear seat and definitely the noise is coming from the fuel pump. I don't really have any issues, but is this noise normal? Thank you
Hey Merry christmas from here in the uk.
Im wondering if you csn help because Im really stuck.
I have a 2008 VW T5 transporter 1.9pd. The van runs well until it warms up. Then it misfires heavily in 4th and 5th gear, under load. ALSO the fuel tank is massively pressurized when I pop the cap. It runs badly with no cap on too. There are no fault codes on vagcom. Could this be the intank fuel pump? Please help. Im desperate now. Thank you
I have a 2015 vw gti -for a few months now it occassionally will hesitate starting. turn the key and it doesnt fully turn over,turn key to off and it still tries to start then shuts down, after 3 tries, it fully starts. in the garage now but theyre saying they cant duplicate and figure out what it is. is this a fuel pump issue
Can you show us how to check how much psi the fuel pump is pushing I know vw has some weird lines and I don't know if a adaptor is need for your standard fuel pressure guage
I like the idea!!!!
@@HumbleMechanic +1 please!
Good video. Maybe you can do a video on AdBlue tank heater units found in the new TDI's. They fail so often these days that I'm waiting for the letter want day now about a recall. When there is a MIL/CEL on a B7 TDI Passat it's about a 85% chance it has to do with the freakin AdBlue system. My '13 just threw a MIL P205B last night at 36,600 miles.
Always a interesting watch own a vw myself with it fear shear of problems
First place l would go is the fuel filter check that first its cheaper to replace if the problem
I have a 2015 Golf Mk7 1.4 tsi and its cranking 5-6s, sometimes more, when the fuel level is 1/2 tank or less. Sometimes it turns on, idles on very low rpm, an then starts to turn once again. When its really low on fuel it idles porly and the engine doesnt run smooth under acceleration. I can hear the fuel pump when i turn the ignition, could it still be a bad fuel pump?
No problems when the tank is filled up.
Did you have misfires and intermittent vibration while idling and cold starts ?
I did. The missfires and vibrations on idle didn’t go away when hot either. I changed the in-tank-fuelpump, didn’t help. Sold it a while back. Nice car, in some ways better than the BMW 1-series i bought instead. But got tired of the never ending repairs.
I also changed the sparkplugs and coils, that didn’t help either.
@@jakommer Thanks for the reply I'm rather worried with mine at the moment can't sell it off with the CoVid damaged economic situation bank are very picky with it comes to financing, Could elaborate more on the poor acceleration that you mentioned in your reply. Many thanks
J R
The acceleration wasn’t poor, it was inconsistent with occasional ”Coughs”. Could be the turbo/engine mapping, i think it’s something most Golf buyers won’t notice. Not the first turbocharged car i experience this in.
But in comparison my BMW with the B48 engine is super smooth and has a very consistent response to the throttle input.
With my turbo r32, I want to upgrade the pump, is it hard to get the actual pump out of the housing without without breaking the housing?
If you’re super careful and warm the pump housing up you can.
I have a 2.0t Jetta, the fuel pump won't kick in, the starter doesn't kick in (starter has been tested and works) and instrument cluster says nothing about the low coolant or anything, voltage goes to the fpcm and out of it.
Hey Charles Is it known fault? My wife’s 2016 golf fuel pump makes humming/buzzing sound wen cars running vw said it’s not warranty issue till it fails completely
I have a mk5 2.0 tdi golf it was driving fine until it snowed really heavy and was sat a few days. I got half a mile away from home when I finally went out and just cut out, but it does tick over. It has no error codes and after checking there is no fuel in the filter I’ve bought a new pump to fit but before I do is there anything else it could be?
I have to rev more to keep my jetta from dying in the afternoon with temperatures reaching 36centigrade. Is it fuel pump??
Interesting video, had this go bad on my mk6 gti.
So I have a 2006 gti 2.0T with a hpfp and I keep getting high pressure fuel regulator performance 2. This morning it was like the car wasn't getting fuel and when I drive it in high gear low rpm it has a fuel cut it feels like. Could all this be caused by the in tank pump going out? Thanks in advance.
I just got a 2002 tdi and fuel pump went kick on just replaced it with a new one and nothing I replace relays fuses and still nothing need help please let me know what u think thanks
Hey humble mechanic, I have a vw polo 1.4 classic 2003, I had opened the pump to clean the sieve now upon replacing it the guage is misbehaving it only goes upto Qtr tank and it doesn't go beyond that mark when I put more fuel when I start the car but the car has gone off due to low fuel several times and the fuel light does not turn on, its inconveniencing, how do I centre in right position?
Hey Charles I have an 09 Tiguan n the transfer pump is humming . Well yesterday the pump stoped humming now my check engine light is on with a p0171 lean bank 1 . Could the pump have failed n caused this chk engine light? (I think so) also I’m very concerned about my high fuel pump failing destroying my can. For piece of mind should I change it? Please help ASAP before I go blowing money n throwing parts at it. Ps it a Tiguan s with a tsi turbo also the car runs kinda good I’ve been having mid range low power like in 2-3 gear lil sluggish .
Hello Sir, i have seen several of you videos and i must say they have been very helpful. Thank you. Pls i have a question concerning my volkswagen cc 2009 in tank fuel pump. what is the resistance value im supposed to get at the pump power terminals. Am i supposed to hear an audible sound on the fuel pump whenever i am cranking the car? My pump gets the right voltage and its power terminals read 3ohms but the pump does not make any sound when i crank. Pls help me. Thanks.
Hey, i have a golf mk6 and my fuel pump is running continuously even when i remove the key from the ignition. Checked the relays but those aren't faulty. What could be the problem?
I have an issue with my 2012 touareg tdi V6 the low fuel pressure alarm comes up under heavy acceleration (goes into limp mode) otherwise the car drives fine. upon further investigation the fuel pressure in the rail doesn't quiet meet the specified value under heavy acceleration.
I have changed the fuel filter and checked the low pressure fuel pump flow rate and this is fine. (1.8 liters in 20 seconds)
I have removed the low pressure fuel pump the strainer is clean and the pipework is in good condition with no leaks.
I have removed the inlet manifold and removed the metering valve on the pump with no metal particles found so replaced the metering valve.
Inspected the fuel pressure regulator on the rail this seems to work and shut off when 12v is applied to it. (after removing i found they have a one use seal so replaced it anyway).
Now the car will not start at all the fuel system has been primed with the electric pump, there are no fault codes but when you look at the fuel pressures when cranking the pressure is only low and doesn't get to the specified 500 bar to start.
Any ideas?
HumbleMechanic - I have a noisy sound coming from the boot. I have been told at last service Seat Garage that is : " "When started there is an electric noise sounds like an electric handbrake arming fuel tank lift pump is noisy but still creating correct pressure. Cost to replace 401.51 "."
Could you advise what to do? Do you think it it fuel tank lift pump to change? Is that the one you show on your video? Cheers mate
yes hi im Klaas i have a 2003 beetle 1.8 turbo replaced my fuel pump and filter still struggle to start it
Hi There, I have a VW Passat CC 2011. I occasionally have misfires while driving for approximately 2 hours or more. This mainly happens when I am idling. Eventually the car cuts off/stalls and doest not restart right away. I changed the high pressure fuel pump, cleaned the manifold from the carbon buildup , O2 Sensors and PCV Valve. I have no check engine light on the dash. What do you think can be the issue here?
Hi there, did you find out what the issue was? I've done exactly the same as you have. Changed PCV valve, O2 sensor, fuel pump sensor, HPFP, carbon cleaning. Only thing I haven't changed is the LPFP. I would have misfires, and sometimes the engine light went on for misfires. Changed injectors and coils but still get misfire issues sometimes... car would also randomly shut off on me, never while driving, but while idling or after long periods of driving. Car would shake violently and then would just shut off sometimes. After waiting 20 minutes, the car would start like nothing ever happened.
Hey Charles, can you recommend any specific troubleshooting ideas for a possible faulty LPFP on my mk6 GTI? I'm experiencing long cold start crank times which is becoming more frequent. It seems to only do this when the car has been sitting for several hours, warm restarts don't seem to be an issue. I'm not hearing the fuel pump prime when I open the door, but beyond that I'm not sure what else I could check. Would pulling fuel pressures in VCDS give any indication? What about key on, wait to prime, and then crank? Thanks!
Driving with low fuel in the tank does not hurt the pump. Fuel run through the motor to keep it cool.
My 2011 tiguan in tank fuel pump stays running for about 5 to 10 minutes after I shut the vehicle off....any ideas ??? Relay location ?
Is there a video or article about fails things to Reset after a VW Car is in a car accident front and/or rear crashes
Does the pump make an audible sound when i turn on the ignition?
Yeah when you turn the key, you can hear whining noise, then you know fuel pump is coming on
Hey Charles i've got a Bora/Jetta V6 4motion its not been on the road for 8 years and I'm restoring it. It had nearly a full tank of fuel which I have drained off. Replaced with new fuel about 1/2 a tank but it will not start, I've been advised to replace the pump (it only clicks in on ignition on but does not charge up like my R 32 does) the pressure regulator was missing the rubber T to the vacuum hose which I have replaced. Ordered a new pump which was wrong and it turns out that this is the 1JO 919 051 G version which I"m struggling to source is there an alternative pump option ?
why I have empty tank on the fuel pump side but in the delivery pump side is full and mark half tank on the cluster on my R32? Thanks
humble please help. 04 with zero bar at rail. left side is the pump and right is transfer g6 right? I have power at pump but no power at transfer pump. would I see power at g6 pump if I have power at left side pump but no operation and zero bar? little confused if right side g6 is the problem of my no start. can't fit the vw tool to pumps separate so can't see which has pressure
please take it easy I'm a vw tech in training.
Hey Charles, love your channel, i have a 2006 Touareg that shuts off after the start up pump is done, the main pump is fine it runs on power probe with no issue, it gets power momentarily so i think its an input issue not output, any direction? thanks
Thank-You once again, VW-Yota😁!!!
PLEASE HELP!

its reaLly hard to get it running .. sometimes its turning a lot before start .. when the engine is hot it start but shut off right after.. until you start it up while pressing on gas pedal
i think its this pump but im not sure
What could be happen if i accedently put 3.5 bar new fuel pump instead of 4 bar?
lol if your car turns on and turns off right away gas pump check if you havent replacement the pvc value nor done a carbon built up clean the MAF senor maybe those can be but those are coming in with codes while the pump doesnt seem to be giving me at my side
My fuel gauge is showing 0 sometimes when I turn off the car and turn it back on it shows how much actual fuel I have then goes back to 0
Is this a bad fuel gauge sensor or
If my car dies while driving, and then restarts after I pull off the road, could that be a fuel pump issue? It seems to die intermittently.
my 06 gli has been taking a few seconds to crank and then start on the first start of the day only. Also, after driving it for two months I'm noticing that it's REALLLY luggy trying to launch in first gear. I've stalled it a dozen times, and thought it was from not having a manual for several years. Then I started trying different pedal-work to launch, bringing the revs up before letting out clutch. nothing. Even if i goose it up to 4000rpm it drops to ~1500 when I let the clutch out. It's really dangerous when I'm trying to make a left turn or coming out of a hill stop, or both. Is this the fuel pump or are the 2.0 turbos just geared this way? All the other gears give me lots of power whenever I need it as long as I'm at 2kRPM or more.
Hi I got a golf 6 every time the car cuts out like petrol but when i throw water on high pressure fuel pump it starts again any advice thanks gavin
The VW Mark 2 fuel sending unit has been discontinued. What can I use as a replacement?
