Be advised, this HPFP can leak internally and dilute the engine oil. The symptoms will be hard starts after shutting down a hot engine for an hour, misfire at idle after the engine has warmed up, and negative fuel trims as low as negative 100. No issues off idle. My Mk7 GTI was at the dealer for 2 weeks and 4000 dollars later it was not fixed. I replaced the high pressure pump and all operating parameters are back to normal.

This video is exactly what I needed to see. My 2006 2.0 T Has low power while trying to accelerate. I already had a feeling that it was my High Pressure Fuel Pump just because I had the low pressure in my fuel tank checked already and it’s working... So now I know that I’m going to the mechanic with more confidence of what’s going on and will get him to check the synod on the pump to see if it’s working. 👍🏾

Here's how mine went out on the 1.8 tsi. Initially I had hard starts every now and then, didn't care much as i thought my battery is not liking the weather and it only happened on cold starts. Then I left the car parked for 2 days straight and on the third the car had a little thump while idling and when you hit the gas while on neutral it revs normally to almost 4K. Then while driving the car wouldn't rev above 3K and would start stuttering until i lift of off the accelerator then it would up shift and keep going. To my surprise, the check engine light was out (bulb was burnt) and upon hooking up the scan tool it showed a fuel rail pressure low code. Changed the pump with a used one and drove the hell out of the car and it was all smooth.

Great video! Very professional presentation.

Thanks alot this was very helpful. My car still starts and moves but once I switch it off. It won't start up again. There's a trick I learnt,pour water on top of the pump wait for engine to cool for a bit then start it up. Hope it works for someone who might be stranded

Hi, Great video. Thanks. My golf 1.4 tsi twincharged was running fine, just had water pump leak, so replaced water pump and also did the full service including spark plugs, engine oil, filters, dsg service, drive /serpentine belts and pulley changed. When I start the car, it started idling rough, no power at all, when press acceleration nothing happens instantly, then very slowly it speed up. Check the spark plug, which has done 1 mile hardly, they were black. All 4 got black. Few codes came up too, initially it was p000A , when I changed camshaft sensor it disappear and 2 other codes came on, p3008 and p0341. Then I put the old sensor back, then only p3008 remained. I replaced coolant temp sensor, thrust sensor, camshaft adjuster valve, put new spark plugs, but changed fuel filter. And also double each & every part for compatibility, bought from main dealer. After starting new spark plugs, I started and it was sane. I again check all plugs, they were all slightly black carbon on them, all 4 were in same condition. No oil, just black carbon. I was thinking may be I left any vacuum pipe back in? But if it was vacuum leak then it’s lean Condition and the spark plugs shouldn’t be getting black carbon on their tips. More fuel coming in as compare to air, that’s why I changed coolant sensor, Can faulty high pressure pump cause this condition, rough idling, misfiring (if look at exhaust), spark plug getting black with in few minutes of idling. Also can these symptoms caused by over filling of dsg oil? I put back same amount of oil (4.8 litres)which was flushed out ? Please help

Great explanation. I am a new used Tiguan owner and having some sort of fuel problem. I've worked on my own cars successfully for the past 30 years but haven't owned a VW yet

replacing my second one and found that the hpfp spring had stayed recoiled which led to the codes, however the hard gas rail wont sit flush to insert into the bottom. also, i really dont want to have to remove the air intake system just to wrench over the rail so that it fits. woo.

There's another failure mode for these pumps. Where the pump is still working but some fuel is leaking past the pump piston into the top of the engine causing fuel in your engine oil. This is bad! I saw a video over at Diagnose Dan about this. The symptoms: codes for fuel mixture too rich while long and short term fuel trim are both showing negative values. Exhaust gas smelling strongly. Potentially test by removing oil level dip-stick, hold it several meters away from your engine bay and offer up a lit match/lighter flame to it. Oil Should not catch fire unless first heated to smoke point. If it does catch fire there's fuel (gas) mixed in with it.

Great video bud, thanks!

Humble Mechanic! Here is bizarre issue. I have a 2007 MKV 2.0t TSI Jetta. I had a huge problem with power. Throttling under 2-2.5 RPM it did go but with low power. Past 2.5 RPM it was totally unresponsive. So taking it home I put it up on the scanner and the codes "Throttle position sensor - G69 signal too high P0123 upper limit reached". And also a second one reading "Angle Sensor 2 for throttle (G188): Signal too low P0222 lower limit reached. So I took the intake manifold off very carefully along with fuel rails very carefully along with the fuel pump and throttle body still attached still attached. I tested the intake manifold mechanically and electronically and it seemed to check out. The throttle body the same. Except that the throttle body when at "0" does not close at a 90 degree resting point. to sure if that where it should be. But the travel values seemed to check out visually. After all that checking out I thoroughly cleaned everything with minefield cleaner. I also cleaned the valves as they were caked making sure only touching the ones that were closed for degree safety. I put everything back together forgetting to putting the dip stick tube on. During starting it took 10 minutes to get it started. Then it idled very rough with intermittent light presses of the pedal. After 3 minutes or so of running it dumped both fuel and oil, gushing directly under the engine. I shut her down and then took everything back off finding no loose hoses or connections. When taking the intake manifold off fuel pored out of the the manifold and throttle body. I'm assuming the obvious on the oil gushing, but the fuel? WTH? Any suggestions?

Just found this video and shed light on the way my car is setup. I have a mk4 gti with the 1.8t and a shop did the build. Couldn't figure out why they had an in tank pump and then a 2nd pump near the engine. So looks like the in-tank is providing the 2nd pump with low pressure volume and then once it gets to the 2nd its giving the fuel rail a higher pressure so the larger injectors can spray what they need. I just had a no start yesterday, and sounds like the 2nd fuel pump primes intermittently. There much be a relay or something that turns it on, not sure where to check it yet though.

Thanks for the data point. I am just learning to use my new scan tool for euro models hoping the learning curve isn't too steep. :) Thanks for another cool video you are becoming my "goto guide" on VW's. Peace.

Can you guys do a video on the LPFP?

Good vid, thanks. Got 145k on my 09 Gti, 2.0 tsi. First time I’m changing the hpfp

Hi any ideas on why my fuel pup makes a loud tappet sound when driving and idling?

I never checked when my last fuel pump went but would bad electrics on a fuel pump cause the fuse in the engine bay to pop? I believe f23 in the engine bay fuse box, on my car it was a 5 amp.

Hi, how can it be diagnosed if the issue is only the High Pressure Fuel sensor and not the HPFP ? I'll appreciate your feedback!

Hi, I have a 2015 mk7 GTI which rough idles when cold started. sometimes it throws up EPC light too but upon scanning with VAG-COM no faults were recorded. Everything comes back to normal if I just switch it off and restart. What do you suggest checking?

Love the channel. I have a 2007 Eos with the 2.0t engine. The car consistently dies when the engine gets to operating temp. Help!

Thank you Mine was actually broken just like that one!

Hey Charles, where can I check fuel pressure on the low pressure fuel on a 14 Jetta 1.8t se? Thanks in advance!

Hi Thank you for your videos. They are very helpful and educational. I have a question. Modified high-pressure fuel pump is beneficial for stock engine or not?

I got codes p2293 and p2295 (Fuel Pressure regulator - Control Circuit Low)

Most of the failures on EA113 motors I ran across were due to neglect - not changing the cam follower. I've found two broken hpfp pistons in EA888 motors. In one the customer told me it was stalling at every light and constantly misfiring for several weeks. It stalled three times at the same green light and wouldn't start again. Along with the borked hpfp it was very low on oil and the timing chain tensioner failed. I tell all my 2.0T customers that a few quarts of the most expensive oil is far cheaper than a valve job. But I digress...

I have a 2008 s3 8p 2.0tfsi which is running lean. Car has a bigger intercooler and a performance chip tune, produces 330 hp @3200. If I drove it constantly under 2200rpm it goes into limp mode with "p0171 lean off idle" code with ltft over 21%. If I drove it over 2200rpm car gives power back and ltft settles at 13-14%. VCDS says that required and actual pressure is fine in both hpfp and lpfp width almost no difference. Lpfp duty cycle is 57-58% at idle and 60-62% off idle at 21% engine load (where usually freeze frame sets - 1800rpm). Cam follower replaced and no wear on the shaft, pcv replaced, injectors brand new (seals too). MAF readings are fine, 3,5g/s at idle, 10g/s when rpm held at 3000, and 208g/s in 2nd wot. Smoke/pressure tested the hole system for vacuum and boost leaks, no leak. Now I suspect that either the lpfp is wearing out or my hpfp is not up to the job anymore as this fault started like 2-3 months ago. Please let me know If I can provide any more info and thank You in advance for helping.

great info on hp ,but what are normal low pressure readings ? i know 45-90 psi what i have is 90psi on start but after 2min presure stays around 45psi even under heavy load / accel ,is this normal or low pump starving high pump ? my high pump was bad , just looking for reason thanks

I'm so mad. I replaced a PCV valve on a 2015 beetle today and the engine bay was getting so hot previously that the top sender on the HPFP broke off while I was working. Doesn't appear to be any way to service that part....so a new HPFP is needed all because of the crappy placement of that solenoid

I’m working on a Audi A4 and i have P0088 code is a high pressure over the normal pressure, i check lines and change the pressure sensor with out any luck, do you have any advice for me? Thanks for your videos are so nice

How do you know if its the standard fuel pump for the high pressure fuel pump thats the problem?

KNOWLEDGEABLE HumbleMechanic Brilliant video thanks 👍 From Nick Ayivor from London England UK 🇬🇧

Ross-Tech wiki link doesn't work :(

I have a p0230 fuel pump primary circuit fault. Any idea on what this could be? It caused my epc light to come on and I lost all boost. I also had multiple misfires shortly after it occurred

Hey what’s up dude, im a big fan! I only have like 2 volts going to the hpfp solenoid? Fuse and relay are fine. I have low voltage in that whole circuit? Have you ever seen this? Replaced hpfp. Thinking the ecu is no good? Does the ecu varies the voltage? Im getting computer ground at the solenoid. Any help would be very much appreciated 🙂🤙 also just picked up from body shop and of course they were like oh it came in that way! They did say they had to jump it and charge the battery????

Can it bring up your O2 sensors saying running rich ? And O2 sensor running lean ? Because I have changed all O2 sensors and still same errors come up! My back fuel pump has been changed but not the high pressure one, sometimes the high pressure pump sensor says faulty even though it’s a new one!

I got a question, does this give a P0089 code? or do you have any videos dealing with such codes? I have an Audi B7

My 09 Tiguan has a no start issue but before the no start car was losing excelleration n before that the pump hummed in the back . Which pimp should I replace? No check engine light

Whats about a6 c6 3.2 p2296 (pressure circuit too high).. Is this a bad sensor on the driver side or bad sensor on the HPFP?

Mine has an extended crank right now and I read the fuel pressure with my access port and it was at .64 lmao but if you wanna slang a hpfp my way that would be nice

Good Day to you (advice needed) I am Charles M. I recently financed a 2010 VW cc 2.0t in Arizona. After driving it to California and back to Arizona a few times and keeping up with the oil changes. I noticed the engine would not start at times after driving to a store I would come out and start the VW it would start than drive 10 feet than stall at times 10mins to as long as 30mins. I also noticed now in California the low oil pressure light comes on after about 25 mins of driving above 40mph. I did a diagnostic check and got 2 codes P2293, P2401. The older gentleman also share that the oil pump on German cars very rarely go out and maybe the oil pan needs to be clean out really well that this can congest the flow of oil once heated causing the pump to struggle. I did finance the Direct Injection High Pressure Fuel Pump - 2010-2017 Volkswagen CC 2.0L 4-Cylinder - Bosch Hoping to solve this issue. I can do the work myself I just would like some advice if you will. Thanks for your time -Charles M. Make it a great day!

I’ve got a 09 Tiguan. It’s using huge amounts of fuel. Low pressure is at around 30-50psi. Engine runs fine and no codes. High pressure fuel shows 37.5-40bar at idle. Any ideas as to what could case the poor fuel mileage? This was an overnight issue and only getting about 200kms out of one tank of fuel.

I had a 2008 VW EOS that had the P2293 code. Low pressure was fine. Check the High Pressure pump. Replaced pump and follower which both looked fine. Got frustrated and tested sensors which seemed fine. Found a fuse marked F6 15amp which was blown and indicated that it was for the instrument cluster in the owner manual. Changed fuse and fixed the problem. I will have to dig deeper because I have no idea why that fuse would have blown and the instrument cluster was working fine. Have driven for over a week now and no problems and fuse hasn’t gone out again. Crazy strange!

I'm having intermitent failures on high pressure pump on a CCZA engine. It started ocurring after my mechanical f*cked my engine when replacing chain tensioner. (16 bended valves). When I'm accelerating, sometimes it cuts the throttle suddenly, then the error code appears. But it's intermitent. Sometimes I run the car for long periods, floorimg it, and no problems. Any tips about it? May be an wiring issue? VCDS shows perfect fuel pressure on idle, didn't checked at wot.

Hi there! I have 2 codes for the hpfp. The car doesnt start. When i check channel 140 with the car off, im reading around 9 bar. Should it be 40bar at that time already or is that good before the car starts?

Hey ive got a Question , On the 2016 1.8 polo 192ps gti tsi DAJA, I need to remove & re-seal valve cover, can the hpfp stay bolted to the vacuum pump & remove it as one piece once the adapter ,hoses & the high-pressure line to the unions nuts are unattached? Or do the have to be seperated before the vacuum pump is unbolted from the cylinder/cover surface ? Thanks in advance

I have a stage 2 cupra running stock is38 turbo at 400bhp 400ibft, on monday the turbo went poof. this was the same day i had my hpfp fit with autotech internals, i logged the car on the road and the requested fuel target was being met, do you think this was just classic is38 beahviour?

Im in the process of going from stage 1 to a stage 2 file on my 1.4TFSi. My question is, should i upgrade my HPFP to a 1.8TFSi or just go straight to a 2.0TFSi HPFP? This is a requirement but im curious to know if the 2.0 version is the better one or would the 1.8 version suffice?

My 2012 Hyundai Sonata 2.4 GDI is still using the original GDI pump at a current 133k kms.

Hey bro. My car just stalled after a short acceleration. I stopped, ran the test vsds.. No freaking errors at all. Strange. Cranked and it started right away. So far nothing i can think of. 140 block measures 40 psi at idle, no loss of power of any kind. Any idea what happened? i was on a secobd gear, pushing gas after almost a complete stop.

How about a rough start and no light ? I changed the injectors plugs coils throttle body Maf. I’m doing that pump as soon as it gets here ! Anything you think I’m missing ? And water pump been changed

Hi I'm having hesitation a lot at low speed from zero to 30 kmh. I did get it at 120kmh too. Its random but the car is running very lean as injectors show. What can it be?

Hi, I have code P0087 and fuel cuts around 4k RPM after an E85 tune with EQT and install of Autotech HPFP (Pre-assembled). Stock turbo. I had zero issues before installing the new HPFP. Bad HPFP internals?

Please post info on testing the solenoid with vcds or obdeleven. Please 🙏

I have been watching lpfp duty cycle in my 2012 gti with obdeleven. At idle, rail pressure bounces between 555 and 580 psi with lpfp duty% between 50 and 62. Duty% maintains a constant value ,idleing, but seems higher on warmer days. All seems fine to me but im curios Can the hpfp suck fuel from the low side? Like if the lpfp is stugling will the hpfp help it? Once every 2 or 3 months i get a long crank start or have to crank a second time to start only after a short trip when engines hasnt reached operating temp. Im thinking the filter is bad since it incorperates a check valve

I bought a cheap 2010 CC and my fuel pressure at idle is 80BAR. Going to try replacing the pump and hope this fixes the problem

Pls do one on the cdl motor

I have some extended cranking time, high pressure fuel rail is 40bar when running, what else should I check?

Hi, I had a code telling me the mixture is too rich in blank one and 2. So i took my car ( V8 4.2L) and they said It's the 2 high pressure pump. I think they are wrong. What are the odd that i get 2 error codes at the same time? Each code is for one side of the engine.

Thank you for the video,i have a problem with this pump, it gets really hot and eventually plastic connector melts. i have replaced and installed a new one but still have the same problem ,What could this be?

I'm doing diagnostic on 2013 Chevy traverse I pull the code p228c regulator 1 exceeded control limits - pressure too low, could this be high pressure fuel pump??

After a long run when I stop my skoda superb 1.8 petrol for long time and then I tried strat. ....it cranked but wont start ....but when i removed the front soft pipe line from hfpp and then strong petrol pressure realsed from the hfpp and my car star immediately ....please please please reply same pump no check engine light

Any tips on how to remove the n276 connector. I can’t get it off well

Damn where did the ross-tech diag help move to? Gota updated link?

I have exactly the same problem! My HPFP is still ticking, does that mean that it works correctly? I have a rattle noise during acceleration at low rpm and random misfires. My car is a VW GOLF 1.8 TSI 2010.

Looking for upgrades to complete my ko4 setup any recommendations

Hey guys, my VCDS reading saying I’m pushing 109.99 on the fuel rail pressure when it should be 130, it’s on a Audi A3 2.0TFSI BWA engine. Is my HPFP failing? Or just the cam follower?

What if you don't get a CEL my car going up hill starting to shake rpm got really low 2010 a4 2.0

2015 TSI Passat. My car started stalling in street about ten minutes after starting. I replaced coils and coil packs and still had issues. Eventually it didn’t even start. I just replaced fuel pump control module and it starts but runs poorly. Runs with little power, stutters, and a “puffing” exhaust. I’m ready to replace high pressure fuel pump. Is there anything else I should look into?

Could we get a video on accessing the high pressure fuel sensor on the fuel rail theres really no good videos on youtube about it

Is possible to develop an oil leak on the seals to this HPFP?

Thank you so much Mark mangano dependable auto wartburg tennessee

The pinder thingy was broken on mine. I pulled off the pump and the spring and it fell to the ground

Does anyone know which online sites to look for a good Fuel Pressure Regulator for 2007 Audi A4 Quattor 2.0? Do I need a new camshaft follower as well or just a gasket?

If I had this problem and my car no longer started, then had the battery and alternator replaced and it still drove sluggish does that mean it was never the battery and alternator cause I’m still having the same symptoms I was having before

hey chariles got 2009 adui a4 2,0 cranks no start i check for spark and it has spark and here is the codes p2296 p0010 ,,,the battry is junk for starters my frind thinks timing chaine ? if the battry is new and its getting spark and if i shot it with starting fuiled it should run ? what ya thurts let me know

Will a high pressure fuel pump cause a vw gti 2017 to take a little longer to start? And cause check engine light?

Can i use an audi Q5 3.2 hpfp on an A6 C7 3.0T.? They looked same but migh not work right. I having some long crank on the mornings, low pressure fuel pump is new .

If the nostart issue is prevalent what is the problem on a skoda octavia 2012 1,8 TSI

Great video good info... i wanted to ask i have a 06 a4 2.o and am getting the P0089 code please shed some light cause i changed the fuel pressure regulator sensor n still running slow. . Could it be the same issue u were explaining? And what is code P0340???

QUESTION I HAVE A 2012 PASSAT 3.6 THE OTHER DAY THE KEY WAS STUCK IN THE IGNITION AND THE CAR WOULDN'T TURN OF SO PULLED THE FUEL PUMP FUSE ON THE SIDE OF THE DASH PUT IT BACK IN AFTER I CHANGED THE IGNITION NOW I HAVE EPC ,P2293 & p0087 any advice Car is in limp mode

how did you move the cams by hand?

I have a no start at my shop 2015 2.0t low fuel rail pressure code. I checked low side pressure with mechanical gauge and was reading 80psi. Using ross tech I'm getting 9 bar rail pressure. I replaced the hpfp and follower and still have 9 bar. I have 12v at the solenoid but no ground coming from the ecm when cranking. Cam lobe appears to be fine and when I rotate the crank I can see it moving. Checked signal at ecm and none is present. I'm thinking maybe a bad driver in the ecm but the ecm has to come from vw Germany so I guess I want to be sure not not missing something here. Any advice would be appreciated. I'veactually have tries 2 different hpfp with the same results think I might have gotten a bad one. Could a faulty rail pressure sensor cause the ecm to not command the hpfp solenoid perhaps.

I just put a replacement engine in my 2006 passat tfsi and I have a p2293 code that is coming and going. I tried replacing the low pressure sensor on the hpfp with the old one from the original engine but that hasn't alleviated the issue. The engine I put in I made sure I put a brand new cam follower in and I'm sure that camshaft is Good as its a warrantied used engine through lkq. Any ideas on what I should try next. Maybe try to use the old hpfp from the original engine?

When the low pressure readings jumping only engine running, what's meant. Thanks

I got 2014 vw passat 1.8t gen3, i am getting EPC light and scanner says Torque limited due to fuel pressure, and it make noises in low rpm when under load. Do i have high pressure or low pressure fuel pump bad?

So i have a problem on my 2012 a4. I went to auto zone and A code of P2188 came up and i saw that it might be the MAF but then i started to look at forums and other people said they replaced the HPFP and its solved their problem hopefullly this solves my problem. Today i had some weird symptoms not sure if its related to this but my car would crank and wouldn’t start unless i would press on the gas pedal and it would start sputtering a little, and a weird smell came from the exhaust but nothing like smoke & yes i have changed the spark plugs and coils so im not sure what this could be any ideas?

What should the solenoid be reading with ohm meter? I replaced mine, was running fine. Now has code p2293 n276.

I just questioned the 11,000 psi on the other video. The reason i was watching them is I got a Tiguan 2.0T (in the shop, independent) Was towed in, no start. 1st time customer. Had misfire codes on all 4 cyls + random, low fuel rail pressure, cam sensor correlation (wish I didn't erase them with out writing them down). The oil looked like tar and the plugs were blacker than the tire. Did a LOF & threw in a cam sensor. The low press fuel is 90 psi. The high press solenoid clicks when grounded. The scanner (SnapOn) has 2 fuel rail pressure fields. One read 40.75-41 bar, the other reads --- but neither changes when the high pressure pump's line is disconnected. I have a rail w/the sensor, high press pump & housing, vacuum pump from a Tiguan I changed a motor on a while back. Plugging in THAT sensor open to the air also makes no change in the scanner readings. I also swapped in the other high press pump, no change. Odd thing is when the low press line is disconnected is when it sounds like it wants to start. With the pcv line disconnected at the intake, it feels like pressure coming out the port in puffs on my finger. I usually get EVERYTHING started that's a no-start. Been wrenching since '96. Had my ASE's and L1 although they're expired (this shop don't value or compensate for them) All 4 coils have spark. This is killing me. And the inside of the car is filled to ceiling with paper and bags, food wrappers and all sorts of hoarder like junk. Hope they're ain't no bedbugs in there. (Thank God the in tank fuel pump works, I wouldn't be going in the access panel on this one) Any help would be appreciated. Also, while the high press pump was out I stuck a screw driver in there and it moved in and out(thinking maybe the cam in there was degraded from the oil condition) Also put 4 new plugs and from the cranking attempts, the look sooty now too. If I think of anything else, I'll add to it.😢😢😢I also had 150 psi compression on every cylinder at 4 cranks. Disconnected the intake tube to see if the turbo was causing the puffs out the pcv port, it isn't. If that pcv line is sitting in place but not clicked on it actully puffs away from the port about a half inch when cranking.

my 2009 vw gti will shake and flash a EPC code any thoughts

All the links and videos are down😭. I just bought a 2014 q5 and first week I have to change this part

I have a 2006 VW Passat 3.6 how do I test the low pressure sensor I know is there is a five five reference signal and a ground and signal wire for the computer

I have a 2014 cpra Passat the engine will stall when warm changed hp fp and low pressure pumps I don’t know what else the engine is storing no codes the car cranks but no start could the crank sensor cause no fuel

Is it a common problem for the 1.8 passat? I feel like mine may be going bad. In some starts it will start and shut down right away

I was told you have to bleed the fuel system when changing the pump

Did VW solve the worn out lifter bucket/camshaft problems? I'm back to wrenching btw lol

Fail p2294 open / permanent fuel pressure regulator, can it be the solenoid ?, which is the relay of the same if it is commanded by a relay ?. Thank you.

Any issues with 1.4 tfsi 2013 Audi A3 8V timing chain ??

Any video on P0087

@humblemechanic hey Boss love your videos I have one quick question I have an 09 vw gti golf 2.0 turbo my car wount start and I have these codes p2293 p0300 p0302 p0302 do u think this is my high preasure pump my car WILL NOT START thank you

My latest oil test on my 2.0tfsi A4 found 2.3% fuel in oil with high iron content (128K miles). Failed camshaft follower into HPFP?
