Thank you for this video. You’ve explained this failure so good that even a child will understand.
My mechanic told me I just had this failure - me not understanding cars that much, I googled stuff - this confirmed what the mechanic showed me.
Fml though, still expensive to repair after all these years :/
I am sure your mechanic did great bussness from you :)
Hi HumbleMechanic, I got a story for all TDI owner that you would not believe. Just recently I had HPFP failure on my 2013 Passat TDI about 2 months aprox 10,000 kms after the emissions fix. It was the classic failure glow plug lights flashing loosing power quickly to never start again. Searched on the internet and used VCDS to scan the car and confirmed that HPFP has failed. I called the dealership and they said HPFP and fuel system is covered under Emissions fix extended warranty (Canada). The only time it will not covered if they find fuel contamination.I thought I would be extra careful After I heard so much about VW finding an escape goat and not to covering things under Warranty. I drained the fuel tank (which I tested was 100% diesel) and there is no way I will miss fuel my TDI as this is my 3rd TDI. I remember filling up at the ESSO gas station and their was Sprinter guy waiting behind me to finish so that he can fill his tank. Anyways I emptied the tank using VCDS and running the pump. After that I went to another gas station and bought 23 liters of Diesel fuel in the can and dumped it in the tank. Cleaned the fuel filter reservoir and change the filter.Next day I Called VW road side assistance and had the vehicle to towed to the dealer. After couple of days I called the dealer as I had no update from them. The service advisor told me that they smell gas in my tank. I said there is no way and went to see the car. When the showed me the tank with fuel pump removed (under the rear seat), I told them how come it seems like its more than quarter of tank. They said that they had to top it up in order to troubleshoot. I asked them what kind of troubleshooting is this, that it needs more than 1/4 of tank. They insisted that it smell of petrol and it may be that I had put gas instead of diesel in the car. I told them that this car has filler neck to stop a gas nozzle from fueling the car. I asked them to do fuel analysis and let me know the results.I called them a couple of days later and the service rep told me that VW was coming to get fuel for analysis. After that I did not hear back from them. I called them again as its now approaching two weeks since they have my car in the shop and no rental was provided to me. They tell me that the service rep is not at her desk and they will get back to me. So finally at the end of day on Friday I call them again and ask to talk to the service rep and she told me that the car would not covered under warranty as it has contaminated fuel (petrol mixed with diesel). I told them that I need to talk to the service manager. When I talke dto him I had few basic questions for him. How did you come to the conclusion that the fuel is contaminated and why did your shop mechanic felt a need to add more fuel to the tank. I gave the car with 1/4 tank of fuel and now its past 1/2 tank. He had no answers for me and told me to talk to my Insurance company. I went and confronted him and still he had no answers. I asked for report on the fuel and he said they don't have any, all they know is that fuel is contaminated. I had my car towed to my home the same day and started documented everything. I did the fuel test with Styrofoam cup and found that it had petrol in it. I did the same test on original fuel that I had saved and no traces of petrol. I once again drained the fuel and refueled and sent it to different dealership and waiting on the response. I have video tapped everything on draining and drying the tank and then refueling with new diesel. Also have the Styrofoam tests on video.I'm so mad at VW dealership and will be brining out my story to the Media. Hopefully its only one bad dealer and not the VW itself. We will see... I will keep everyone posted.I keep on remembering the VW CEO statement, We have to build the trust again.. yeah right.
Keep us up to date on this
I've been considering a 'fixed' Dieselgate Passat. This story scares the out of me and makes me thing a hybrid might be a better alternative even though I really want the TDI. Sooooo sad! I hope you finally got your car repaired under warranty -- and then exposed this dealership to the universe!!!! This is a news story waiting to be told!!
How did it go with the 2nd dealership?
You post a novel like this and leave it with a cliffhanger? Can you give an update?
This poor guy got screwed
Great video...any thoughts about the CP3 pump some have been retrofitting to TDIs as a way to get away from the issues from this pump? Or using aftermarket filters to protect fuel system components from a HPFP catastrophic failure?
yea.......
I wanna see a CP3 pump swap on a EA288 TDI.
Thank you for the video! my pump failed at 138,922 miles in October 2015, on a 2010 Jetta sedan TDI, the dealer quote to repair was approximately $4000. The dealer called VW to see if they would repair it, "no". I called myself and "no" As in your video it is a hard stop warranty at 120,000 miles. The dealer has one or two more cars with the same failure. As for electrical, my trunk stopped working as well as the stock radio.
I've been told that "Certified Used" post-Dieselgate TDIs have all had their fuel pumps replaced or that they're all under a new warranty. Do you know if this is true???
Our 2013 Jetta TDI would not start this morning. P0087 code. Dropped it off at the dealer. Here's hoping they don't say it's bad grade diesel in it. Nothing but shell fuel for us.
I sent you a message on fb and this was what happened to my touareg. There was no check engine light 😢😢😢.
please make a video on vw amarok 2.0 tdi engine rebuild or power loss.
Any gauge for the percentage of these pumps that fail? If a person was replacing their timing belt, would you recommend replacing the HPFP at the same time?
US failure rate for the CP4 in VW TDIs is supposedly 7% compared to Europe’s 1% failure rate. Some people have conjectured it’s due to the ultra low sulphur diesel sold in the US. Adding a lubricity modifier to your fuel may help (sulphur increases lubricity of diesel fuel, so adding something else in its stead should help - Hotshots EDT is a popular option).
Rather than replacing with another CP4, it’s worth doing a CP3 conversion. The CP3 is extremely durable, does not have to be timed, and can flow a lot more fuel. Pumps + retrofit kits typically run around $1000, which is a bargain compared to the ~$5k cost of a CP4 failure.
I think, the pump has no timing marks on it and you can not adjust the timing, because it is a common rail system. I did an engine rebuild on my 2.2 diesel nissan Xtrail and the pump had no timing marks on it and no info about it in the service manual. It just creates pressure to the rail and the pressure regulator regulates the pressure.
Fortunally Nissan has it as replacement part -200€, but the manual has no word about it.
The major cause is wear and caused by low fuel quality and ULSD.
There are many debates about adding 2Stroke oil on the internet. I have a document from Bosch that they tested the pump with ULSD and caused major wear to HP pump parts. They recommended to improve lubrication of the diesel fuel, but with what, Bosch did not say.
One diesel truck forum did a lab test about different additives to improve lubrication.
The most cost effective was adding 200:1 of 2 stroke oil to the diesel.
Some say that it caused/causes pump failures, but i do not believe that BS.
I think using 2SO is like garlic to a man, i like garlic and my diesel engine likes 2SO. Runs smoother and hopefully prevents pump and injector wear.
I'm considering buying one of these, did you ever test this yourself? Do you think it helped or hindered?
Humble mechanic did they change this pump to a different pump in 2015? Should we replace it when I do the timing belt? I have 2 2015 tdi one Jetta one Passat also a 2014 tdi Jetta I'm now worried. Advise please
Hi, can you make a video for the 2005-2008 1.9L tdi?
Great video. I've always wanted to take one of those art but they've always been under core charge. Have you seen any of the new pumps that we've been putting in fail? I know they have a parts super session. If they haven't what's been done that's fixed the issue of them failing?
Great job mate!
Thanks for the vid, Charles!
do you know where the vacuume pipe off the fuel regulator goes to my car is a VW MK4 GOLF 1.6 16V AZD ENGINE. The previouss owner has bodged it up with 3 seperate bits of pipes and joined them together when i pulled the pipe off the regulator it also came off at the other end cant find where the other end goes. I have a missfire so checking for vacuume leaks tried spark plugs an coils and commpressions are good to also cleaned injectors still no change. Cheers man
Man...I really enjoy your channel, and you in general. Your doing some good work when you can make me interested in VW sir! (Subaru guy here...and self proclaimed Snap On addict as well)
+Mike Henkelman Thank you very much :)
+HumbleMechanic i've got a cp4.2 from a duramax sitting right beside my computer, the exact same set up, but it is a Bosch as well but has 2 pistons and cam followers, i'm willing to bet the pressure regulator is the exact same
Mike Henkelman you must be broke so. I hate that snap on van 😂
Im going to try my luck and maybe you will reply to me... I have a Audi a4 b8 CAHA engine which uses this exact pump. The issue I am having is the car cranks but doesnt start.. Have checked codes with VCDS and its showing rail pressure too low and rail pressure too high.. Where to start on this? Should I replace the easy parts first, fuel pressure sensor, fuel filter, fuel sender, fuel regulator valve or should I go straight into replacing the fuel pump itself?
If I remove the fuel regulator on top of the fuel pump do I have to release the pressure in the system first or can i just unbolt the sensor and pull it off to see whats inside?
Thank you.
misinformation. failure occurs from poor pump design. roller bearing and piston has nothing mechanical in place to keep roller perfectly parallel to cam causing roller bearing to turn 90 degrees and then cam lobe eats it up which is where you get your metal shavings from. I still have my cp4 in pieces. will post video one day
What would be some additives that you could recommend to prevent an algae clot? I seen zmax
In the movie Kelly's Heroes, one of the Tiger tanks has a problem with the fuel system. After all these years, German fuel system problems still exist!
On my 2015 1.8 TSI, we had a camshaft recall and I expected a new camshaft because the recall mentioned Sintering and shaved off lobes. Yet I am now told that an ECU flash solved the problem. Are they being honest with me? Can you tell me why a flash makes a difference?
+Minnesnowtan just shot a quick vid about this exact question. Should be up later today.
Can a failed hpfp cause the lift pump in the tank to go bad?
Hi.. i having question on diesel fuel system... my diesel engine common rail pressure read up to 1000 bar during cranking.. and can hear high noise of knocking from my engine, after let it idle for 3 to 5 min, the CRP drop to normal idle reading 300 bar.. checked and replaced the new SCV, however the issue still persist... need your humble advice.. thanks..
THIS is why people drive Toyotas.
Not related to this but i have a 11 jetta se with transmission problems and it throw a whole bunch of failure codes. Is there anything that commonly goes wrong? Can it maybe be a diy to replace it i have a little experience working on cars but not a lot.
Would you diagnose the same way on any other vehicle make for high pressure fuel pumps?
Nice
Unfortunately I had a catastrophic failure. 😢
why does the ceramic break?
I have 2016 tdi fault code 16113 fuel pressure to high, fuel filter ok low side ok all fuel sensors ok,what thoughts on this thanks.?
I think is more low fuel pressure like P0087 code issue.. but be careful..do more research
Just started watching your channel. Are all VW with these fuel pumps ticking time bombs then?
+Anthony Nowlan by now, most have been replaced. We don't see them fail at the rate we used to.
unfortunately, yes
magically, quality of diesel has improved? NO me thinks. but then again, now that crude price is lower, no need to add that old deep fryer oil to the barrel...
hey Charles I have an 09 jetta tdi and every once in a while a check engine light for low fuel rail pressure comes on, do you think the pump has failed or is it just a bad sensor?
I would lean more on the pump than the sensor. When they don't come apart they can randomly set due pressure faults.
HumbleMechanic do you think this is a problem i should worry about because it only happens like once every couple months then i just clear the code.
+sizeOVERstrength I would want to get it fixed. Id hate to see it go kaboom
+HumbleMechanic i've seen inside a duramax one that came apart, i wanna see if its the same thing with this pump, usually the Harding on the cam lobes fail and chew up the rollers. gets expensive quick, if ya don't mind!
Start with the filter and work from there I would say. Maybe it's due ?
Another reason Pump Duse are better.
Now I feel lucky that my 09Tdi has never blown a pump.
Near the end of video really makes me knock on wood I have over a 130K glad I am most likely getting a newer GLI within the next month or two
if you live in a state that uses bio at 2-5% it saves the life of HPFP's
Help had been appreciated!
Applies to Audi A4 B8 TDI 2009.
The fuel pump under the car, pump number 2 (not the one in the tank), had oxidized the cables so that it did not run, which resulted in no fuel to the engine. Took a while to find the fault but now that it is fixed the car does not start
I have bleeded / aerated the systems fuel system using vcds.
The sensor in the common rail gives values that the pressure in the common rail is only 9000-12000 pa/h (approx. 10 bar) Should be up to 280000 pa/h (approx. 280 bar]
After cranking around the engine a few laps, check oil level pops up on the dash.
Have checked under high pressure regulator valve where there is no metal from the High pressure pump which is usually if it "collapsed"
Also tested with new battery because old was a bit bad.
Anyone have any good idea where to start next?
Are there any ways to check if the High Pressure Pump is working?
Any sensor that needs to be reset?
Maybe you sort a problem. i have we same situation.
@@MrTaddelis check secondary fuelpump under the car, the connector was oxidated
800 bar???? Maybe 1800bar.
Anyone know if the CP3 pump would fit an MK6 Jetta TDi?
It is my understanding that Bosch makes a CP3 pump that fits the MK6 TDIs, but i have not been able to find one.
@@mrorganic88 look at darkside developments
Good morning , I have 2.0 16v TDI with cp4 Bosch , Audi A3, the trouble I have old fuel inside of the car
At this point I decide to clean fuel tank and fuel pump change fuel filter. Up to here all good after 30 starts the motor start ok idle to 3000 rpm but the problem at the next day don’t start any more , after this point the fuel is empty on high pressure circuit and don’t start any more. How I can solve , how I can clean all the high pressure fuel circuit please ligth me. Thank you in advance. Good job
I recently bought a 2013 Jetta after months of researching the TDI, and I just wanted to let you know your videos are amazing, and I am definitely thankful that someone is producing content like this. Please continue the good work.
Hell yes. Thank you so much
Any thoughts on what owners can do to prevent this? I bought this car thinking it would was nearly bulletproof, now I feel like I've got a ticking time bomb. Should we be dosing diesel with cetane power service to lube the fuel system? Is there a specific pump that does better? I've noticed there are a few different SKU numbers for OEM pumps.... 03L130851AX vs. 03L130755A is there a preferred alternative?
X means exchange (refurbished)
800 bar? Did I hear that to right? That's like 11,600 psi.
+jgreenjeans
Yes. 2.0 Common Rail engines run 1800 bar on the rail. (Yes, 26,000 PSI).
Holy shiz! I was thinking the same thing
A fuel pump failure leads to a $6000 bill? Another excellent reason to never buy a Volkswagen diesel, a ridiculously bad design
The CP4 pumps are used in several diesels, not just Volkswagens.

My '15 Passat TDI had zero symptoms of a failing HPFP. No DTCs (p0087 low rail pressure, p0088 high rail pressure, p0191 pressure sensor range), no odd pump sounds, etc. However, did have nearly 210k miles on engine. On pulling my metering valve, I found one big piece of metal and just a few little specs of debris in the screens. So little debris that one Q-Tip was able to clean everything up. Replaced my HPFP two days later.
Just thought it was odd that everything was working perfectly and yet.... caught it just in time.
You lucky mfcker
it's TOO expensive, it's stupid. should have been a recall, 100%. mine just went out, and i'm out 5 grand. for a jetta. not a lamborghini, not a fun performance upgrade.
I’m not sure now, but for many many years vw covered them all. Even if the car was mis fueled. I did tons of them. Only 1 and maybe 3 total in the shop were custom pay.
failure comes from poor fuel, WATER KILLS A CP4 IN SECONDS, GAS kills it is seconds as well, and poor filtration! use ONLY VW filters... same thing for GM's with the duramax i have cut open alot of fuel filters and only one has had the water membrane in it which was OEM
The OEM filter is made by Mann
Kevin Rogers winx filters are not good? Just replaced mine with an winx filter
The OEM filter is not made by Mann. It's made by Mahle
yay finally you got them!, i know i pestered you a lot about these HPFP!.
I remember that when these came out one of the problems was the shoddy US-style "euro diesel" that had very very low lubricity, the situation has improved i guess from 09(but euro diesel is still much abrasive than cheap diesel, cheap diesel has 500ppm sulphur, euro-diesel has 10ppm, and as you all know, sulphur is a lubricant)....
Also, the design is shit, why does VW LOVE cam-operated pumps so much(other than to fleece customers) is beyond me, they're terrible!, look at the petrol pumps you showed that the follower and cam get eroded to destruction!, look at this!.
In 2001, we had a 2L Citroen Xsara HDI, that thing was one of the first common rails(and very high pressure to boot), with piezo injectors and also used a Bosch pump that was fairly long, what's notable is that engine was designed to run on high sulphur diesel so we could fuel it with the cheapest stuff there was, it could also run on euro-diesel no problems. I don't know why didn't VW copied/licensed that pump design from PSA..... IIRC the Xsara pump had 3 cylinders, this one that VW uses is one cylinder only :S
Price here in Australia is $2200 for the pump . crazy prices
i bought a new one from ebay seller in Perth about $1300 to fix my touareg 2008 3.0 tdi with 89k klms. all going great now but added stanadyne 2 micron kit plus moly additive every 2 tanks. good things in life are high maintenance
Have you worked or seen the Hyundai CRDI 2.0 diesel engines on 2016 Santa Fe ? I am getting code p1186 p0087 on a diesel engine, low fuel pressure, symptoms it stalls if u pass 60mph, I restart and it starts but won't go higher than 60-70mph, I replaced fuel filter, cleaned tank wasn't bad, changed rail sensor. Weird thing is whe. I replaced rail sensor it worked fine for few days, then started stalling again on higher speed or when I step on it, I had to accelerate slowly so it won't stall
How to prevent it though? I'd love a used to tdi wagon but a several thousand dollar repair is enough to turn me away completely.
getting fuel from a quality gas/fuel station, adding some sort of fuel additive to give the fuel extra lubricity can help.
Switch to a Cp3 pump, but I’d say you’re more likely to have it never happen even though it happens too often.
The warranty on the TDI powertrain has been extended
It's honestly better to take a car you are interested in and research the common failure and service due at miles. Take the cost of what those repair and wrap it in what you plan on spending. Because in the end a used vehicle has great appeal but the maintenance is the same as it was new. All used vehicle need something or another but in rare cases we'll documented service history of those service may be the vehicle for you. Just educate yourself because not all repair shops will be and you're money will be wasted without someone knowing what they are doing
I really like the video. As an owner of a vehicle that could suffer a HPFP failure at some point, It would be nice to learn more about how to prevent a problem, and ideally some assurance that this is not a VW design problem. Are these pumps failing due to no fault of the owner, and if so, why doesn’t VW do a recall to correct the issue. Also why is there no aftermarket solution to prevent pump failure from damaging so much of the system. Seems like a design problem that VW or someone should be able to fix.
What did u end up doing? My hpfp just failed
@@CK-ui2kb Same I think I am going to repair it :/
My 2010 Toureg HPFP just failed catastrophically with no apparent cause. I am finding multiple revisions 059-130-755-BC and 059-130-755-BT. The latest BT model has gone up $300!! Has there been any improvements that keeps this from happening again? anyone know the difference between a BC and a BT rev pump?
Hello sir, I have 10 renault dxi 240 trucks. Out of these 3 Renault dxi 240 cars have some problems. Startup is OK. But after 2-3 minutes after starting, the rpm does not exceed 1500 and the speed does not exceed 60. I don't understand what the problem is, please solve.
this happened to my car and in Canada apparently there is no extended warranty. vv Canada kindly told me to screw myself when i called iv owned 3 vws so far and i will not be buying another one
i have a 2012 VW Jetta TDI. Had a HPFP fail. I have replaced HPFP and most of the system. i primed the fuel system before starting. engine runs very good smooth for a TDI. but when on test drive it keeps setting the P0087 code. i have went back and check pressure sensor. and the fuel pressure regulator. both test good. checked wiring from regulator to ECM good. woiuld you have a ideal that i could test replace ?
I changed my water pump on my 2012 volkswagen cc sport and now I have a fuel leak any help would be greatly appreciated Thanks
Just passed 375k on my original pump! I’m just discovering how much damage these can cause so I’m going to replace it right away!!
If you dont mind me asking what year is your tdi? Mine is a 14 and is close to 100k miles.
@@ShotGunner5609any problems yet? About to get a ‘16 with 160k miles …
@@haleywalkerc.9605 honestly, nothing that wasn't my fault. Everything has pretty much been a side effect of the wear it gets cus I live several miles offroad. Do your oil changes on time or really if you can. Get a fuel additive for lubricity to extend the life of the high pressure fuel pump. And make sure you change that fuel filter! If you have any other questions feel free to ask.
Just lost pump, 134000 miles, metal in fuel tank, both electric pumps need replaced
Not really acceptable service life, return back to fuel tank needs a filter.
Not a very good design, diesels are supposed to be tough.
And run for 40000, 500000 miles.
Vw engineers really did a poor job designing this powerplant.
I have to choose to scrap sport wagon or pay to fix it.
I'm not going to buy another VW.
Vw didn’t cover it?
Hey Charles, what is your view of some of the kits you can find to convert these TDI engines back to a CP3 pump? Is it worth the cost or can the same thing still happen?
I think they can be great. I don’t have enough personal experience to add other than it’s an option. The TDIClub folks seem to like it. They are a picky crew
After owning a skoda yeti, ill never ever buy a VW group car again. I never knew the VWs were so reliable, expensive to repair and pathetically over-engineered.
This will be my last VW/Audi ever. Life is too short to be dealing and getting frustrated with crooks like VW. Next time Lexus or Toyota, Boring Yes but doesn't give you a heart attack.

+James Michael probably is good prevention. mine had 92k klms which is ?miles. just ticked over 100k with no issues after new pump and not replacing entire fuel system as was recommended in other threads. i did put 2 micron inline filter after factory filter and replaced both at 97k. there was still some shrapnel in factory filter housing. will change filters again at 102k. with moly fuel addative (highly recommend @ 10ml to 15ml per 10 litres) it is actually running better and smoother than before and way more klms per tank. Maybe that was the sign of pump going? klms per tank were getting less and less. that or crap fuel.
ps. never thrash a diesel unless u have heaps of liqui moly in tank. keep rpms down.
no worries James. if i were u i would just put in moly now ie today...get 2 micron installed ie next week... and wait for pump to blow up or replace with no rush.
James. just went through my previous posts and failure happened at 89k klms which is 55k miles
save your money me thinks. too extreme. I love my touareg. The drive, feel and comfort is awesome. I plan on keeping it for long time so I will do all my own services and repairs until I have to spend more time with it than the kids. Other than hpfp, it has had no major issues. My missus' car is australian made ford territory and I am replacing suspension bushes at 60k klms. total rubbish in quality, drive, road noise...you name it. AWD in touareg really makes a difference. it is glued to the road. i never knew cars were meant to drive like this. I can never go back now
you said 800 BAR ? That's like 11,000+ psi. Is that correct ?
pretty close. LOL ITS A LOT
My Hpfp just went out on my 2013 Sportwagen took it to Vw
My warranty just expired 20 days prior
They want 9grand. This is the first and last Vw I will ever Purchase.
Buy a CP3 retrofit kit from Matt Whitbread... Problem solved.
Can u send me a link?
My crdi (Hyundai Santa Fe diesel 2016) is throwing code p0087 p1186
Symptoms: stalls if I accelerate hard or if I speed up over 50mph when it happens I restart it and it fires right up on 2nd attempt. While idling I can rev it past 3k rpm no problem, but while driving it will stall if I go past 2k rpm or if I floor it it'll stall. I replaced fuel filter, fuel rail sensors, whats next ? Or how do I correctly diagnose it, or what do I look for in live data ?
Everything checks out good including internal high pressure pump plunger and lobes. Still no start. Im replacing pump and injectors anyways but i haven't found the problem yet
Could you do a video on Diesel Particulate Filter for 2011 TDI . As im seeing a P0401 on my CEL
I have an 02 1.9 liter VW TDI and when I try to pull a vacuum on the return line of the injection pump no fuel will pull through all it does is create a suction and then will collapse my hoes. Is this supposed to happen or should fuel flow through the return freely when I connect a vacuum pump up to it to check my fuel system for clogs?
Hi,
The diesel leak off pipe is keep on pushes out , the leak off non return valve works fine..but there is some kind of block that goes to the pump...
Any idea ??
Happened to mine a month ago cost a f#####g Fortune
My 2020 Skoda Octavia suffered hp fuel pump failure and there are metal bits everywhere in the fuel system. No warning lights at all. Absolute garbage. Happened 1 month after warranty expired.
Another symptom from experience is you will hear thumping coming from the back of the car and significant loss of MPG’s and fuel.
If I only know that before my pump died , I notice more fuel consumption since I bought that car (compare to previous same VW Passat 2013 TDI what I have before) and the difference in mileage between the cars was almost 300km on full tank of diesel (my record on first car was 1350 km on full tank , compare to 1000 km on the second car) I learn the hard way about the failure of a high pressure pump , so now I end up with good looking car but totally not worthy of fixing because parts and labor cost big $$$$
Hello Charles . Am a taxi owner in north Greece I have a skoda tdi 1.6 2013 . I need spare parts for high pressure pump 03L 130755E..BUT I cant find ..I have just a small leak on belt......so I need just gasket
I seem to have a FPR failing but see no metal on it. When I test it by powering it up, it won't actuate, won't click. Could I have algae growth binding it or is it metal from the HPFP that I'm not seeing?
Its just maje noise with me .what i shoukd to do ?
Is there any sound that can tell me i have issue with that pump? Coz i can hear electrical humming from 1000 to 2000rpm when I put the pedal on the floor and only when im in gear. I have 2013 audi a3 8v 2.0 tdi.
My Mk7 is coming up on 65,000. I'm the second owner, bought it at 22,000 on the clock. Minus a minor, ongoing parking sensor malfunction, the car has been perfect!
What can I do to prevent this catastrophic fuel pump failure, and or detect if it's going to happen?
Some people have been saying to replace the CP3 ($1,000?) now, just to be safe.
I love this car and I want it to survive to 500,000 miles or more (if possible).
Great Video!!! Have a question. Is It normal lisen a little sounds from the pump when i put in contact the car? The sounds continues while is in contact. Thanks
My 2012 Q7 TDI just experienced High Pressure Fuel Pump Failure. Car has been at Audi dealship 35 days!!!! They are blaming covid-19 for staff shortages. I am beginning to think they don't care because it's a warranty repair. They have me in a 2020 brand new loaner car. You would think they would want that back?! Funny part is, I diagnosed the problem for them because I am an avid Audi Blog reader and had heard about it. They said they weren't sure what was wrong with it, I sent them a summary of the fuel pump failure and they quickly responded with, yep that's the problem! I was driving along at 55mph when the engine just quit! Scary experience. My question is, how much actual labor hours are required to replace all the fuel system parts? As I mentioned they have had the car 35 days already.
Just got a jetta tdi has 165000 miles, would you say if it was going to fail it would have already? I am going to pull the synoid tommorow fingers crossed, if its good ( which its not displaying symptoms) will an additive with more lubricity help..... love the channel!
i bought a cr170 audi a3 2.0, and if i rev the car or its under 1500rpm, i get a weird buzzing noise, my mechanic reckons its the regulator, is this true?
Hi im from SA i have a vw Cadddy that has no power and no fault codes i checked the vacuum all seems fine but it has no boost i replaced the turbo aswell but still no victory
The exhaust is open
The camshaft doesnt look worn
Turbo is new
No troble codes any ideas
Damn I hope this is what’s wrong with my car I have taken it to vw over 10 times and they can’t figure out what is wrong with my car that she will get stuck at a speed and reduce after going on the highway, they are replacing fuel pump now, but they have done just about everything including a new engine and still she won’t work right does the same thing.
TOYOTA DONT HAVE THE NUTS TO SELL DIESELS IN NA
I have this kind of error p229b00 and i dont know if i need to change whole pump or just a pump sensor. If someone could answer this would be cool
I have a 2014 Volkswagen Jetta TDI is it bad for the high pressure fuel pump after changing the fuel filter to cycle the key on and off ?
Hey mate, I have a question, when these are replaced with a reconditioned part, do they need to be activated or something done with their software? Ive just changed mine with a reconditioned one, the original just started failing it was making a loud clicking noise and I stopped using the car, no EML or glow plug lights came on, no loss of power or missfire, after i changed it with a reconditioned one flashing glow plug light and eml came on the code im getting is P0087- Fuel rail pressure too low, my question is do these need something done with the software so they work properly or is it just a defective pump?
Thanks in advance
Such bullshit that VW has not addressed this issue. A slight change in pump design could fix this issue once and for all.
I have a 1.5 TDI in fuel pump area little dirt marks are there like diesel dirt how should I know my fuel pump is leaking also no codes my car is well maintained
Damn good video. My car threw the glow plug light flashing and within about 1min she shut down. Towed it home and pulled the sensor to see lots of metal shavings. Also used vcds and there was zero high pressure showing while trying to crank.
Duramax cp4 pumps are trash as well. Junks the entire fuel system. Much easier to proactively do a cp3 swap
Your video just calm me ahahah, my low pressure failed, changed it and the car run but go straight in limp mode, glow plug flash in the dash and will start to stall after a drive around the block, so i think its the pump controller . Well made vid bud
misinformation. failure occurs from poor pump design. roller bearing and piston has nothing mechanical in place to keep roller perfectly parallel to cam causing roller bearing to turn 90 degrees and then cam lobe eats it up which is where you get your metal shavings from. I still have my cp4 bosch in pieces. will post video one day
Thanks for the video. Had this happen to my 2012 tdi sportwagen.
Not mechanically inclined so I'd be paying to have it fixed.
Now I've gotta get someone to buy it off me with this issue present
i have a 2006 passat, dealer says camshaft worn out and it need a 3000 repair, i will work with an updated to fuel pressure pump since camshaft does not seem to be that bad to me.
This is a completely overhyped problem. I work at an independent vw/audi shop. We sell tons of a3 and jettas with 2.0 tdi. Work on tons more. We have yet to see one failure. Most failure is caused from contaminated fuel. I.E. water, crap bio diesel, people even put gasoline in them.
Today that’s very true. Back when this video was new, it was really common. We were doing 2-3 a week st the dealer. Most weren’t misfuel issues.
I’m suffering w that problem. The dealer blames it on contaminated fuel. I am the sole driver of my vehicle only full diesel almost always at that one quick check in my area. The dealer needs to substantiate the contaminated fuel allegation before they void my warranty yet they’re refusing to! Wth is contaminated fuel????? I only fill diesel at the same quick check yet suffered and abrupt failure of my fuel system.
@@HumbleMechanic how can a dealer substantiate a fuel contamination allegation? I have a 2014 VW Jetta TDI that was part of the emissions fleet modified and resold by VW. I have that same exact problem yet the dealer is voiding the warranty under pretense of contaminated fuel. How could the contaminated fuel be adjudicated? Ie how do I know my fuel is really ‘contaminated’ n whether that contamination is what caused the fuel system failure? Please answer me. I’m stranded without a car for 3 months now. Bought that Jetta for $8k in 2019 now in 2022 it’s costing me as much to fix it! An abrupt failure on the Highway without warning out of nowhere!
Sooo by your logic just because YOU haven’t seen the problem that means it doesn’t exist? This happened to my 2010 Jetta TDi and I had to shell out $6,000 to fix it because I was sitting at 121,000 miles. In order to qualify for the DG Buyback I had to out of pocket this so the car arrived at the dealership under its own volition. This pump, the CP4 pump in Touareg TDi, the larger Bosch pump in the Ford 6.7L Powerstroke….from THAT era were known to catastrophic failure. It is VOLKSWAGONS story and excuse to NOT fix it and blame it on contaminated fuel. MY FUEL was GOOD but they flunked me because I didn’t have the filler neck mod, which ESSENTIALLY was VWs recallesque solution. Bbuuuuuttttt I always have my VWs serviced at the dealer…wwwhhhyyy didn’t they put it on my car. You’re right. Completely overhyped.
Well where is the list on what to replace.
Change(conversion) this crappy pump with the older CP3 and wouldn't be problems!
Major failure happened on my car and it took 2+ weeks, and it would have cost me 7k to 10k repair had it not been covered by VOA. Most cars have it covered under the 120k mile extended warranty.
Hacky2447 Wonder if that’s the same now adays
I had this happen to mine 3wks ago, Ext warranty won't cover it at 130k, It's completely out of pocket, 7k to fix, well I'm not paying this, I am surrendering my car back to the bank I financed it through. It's their problem to deal with.
@@ElRojoDhablo666 I sold my car back to VW as they offered me 13k for it a very long while back. Never regretted that decision because no matter the fix they offered and warranty coverage it was a ticking time bomb waiting to happen. Although at the time they didn’t have the fix, so it was my only real option anyway. Lol
im needing to replace one on my 13 Cayenne Diesel. I can not find anything that shows how to remove the whole pump.Any suggestions?
