VW Jetta TDI High Pressure Fuel Pump Replacement (DIY) volkswagen jetta auto technician

- The original diagnosis of this 2004 Volkswagen Jetta was that it was leaking oil from the high-pressure fuel pump. On this particular set up, engine oil lubricates the high-pressure fuel pump internals. The seals inside the high-pressure fuel pump were old, causing it to leak oil.
I'd rate this job a 4 out of 10 (with 10 being the hardest). It's fairly easy to do.
You'll have to remove the coolant housing to access the high-pressure fuel pump, so make sure you replace the coolant that is lost during removal. Also, be sure to bleed the air out of the coolant system after you pour more coolant in. Otherwise, the vehicle will start to overheat.
And that's all there is to it folks. Thanks for watching this video, don't forget to hit that like button & subscribe for more auto repair content.

I love how realistic this video is, people usually cut out the parts of them dropping stuff or struggling to reach the bolts etc but i could relate this so much lol. Great video, i may have to do the pump on my BRM TDI soon. It starts to have trouble starting unless i keep it over 3/4 tank full
I try to keep it real as much as possible. Check the pick up tube in the fuel tank is reaching the bottom, and make sure it’s not damaged before you replace the high pressure fuel pump. Thanks for watching!
Yeah double check your pickup tube, could also be the lift pump going out, but idk.
Well done👍.....your skills are going to be priceless in the near future.
Great video! I always like to watch someone else tackle a repair before I attempt it. Btw to get that one bolt behind the coolant neck, you can use a long ball end Allen key on a socket. Bought a 7 pack at home depot for $21 and it had the 5mm needed. Air box has to come out to do this tho.
Thanks for the support and feedback buddy
U r good mechanic. Thank you.
This was great
Thanks 🙏
Im pretty sure my HPFP is leaking, too. I was excited when I found this video, but not anymore lol because my heat/heater core doesn't work (like that when I got the car) and don't you need that when you have to burp the system? When you took off that coolant tube/housing I got sad haha now I dunno what to do...
Should have shown to purge the air out the tandem pump by pulling the return fuel hose out of the fuel filter and cycling the key like the manual states !
I will keep that in mind thanks
Can you please explain on this more? So when you're all done installing the new tandem pump, and you hook up/plug everything back in, before you go to start the car, you should do what exactly? cycle the key to the ON position but not Starting it? why pull the return fuel hose from the fuel filter?
@@kevin.lefevre well ELSA (vw offical manual) states that you should use should use some sort of vacuum mashine to extract the air out of fuel system (possibly the same mashine that is used for purging the cooling system).
Well since you probably don’t have that, disconnect the return fuel hose (so that the fuel with air can more easily escape) and cycle the key for a few minutes without starting the engine (when you cycle the key the lift pump in the fuel tank works for a few seconds and pushes the fuel through the system). When you have done this enough time, connect the fuel hose back.
Even when doing all of this you will still most likely need a help of starting fluid to to successfully start the car. Good luck!
@@kevin.lefevre hey there buddy yeah I should have showed me starting it up.I just cycle the key a few times and it fire right up.What do you mean about return line
That little hose u cut off in the beginning costs like $200 because it only comes as part of a kit
It's not actually an hpfp. Just so you know. That's on the common rail system. This is a pumpeduese which the injectors create high pressure from rotating against the camshaft.
Thanks for the knowledge! I never really looked into it before now. I truly thought it was a common rail like the ALH. The sad part is I own a Jetta just like this one lol you learn something new everyday !! I’ll make the correction and pin at the top of the comments!. Thanks 🙏🏽
@@AlexTheCarDoctor good effort replying so fast
@@AlexTheCarDoctor still not quite correct.. The latest are common rail. The alh has a ve injection pump
@@crazypeoplearoundtheworld304 I’m going to look into it more. I don’t do many diesel cars. But like I said, I do own one so I’ll have plenty of reason to research and learn more about them.
Bummer thought this was hpfp replacement not a tandem vac pump
Great info, thank you, need to do this on my son's 03 Jetta. Found the same area wet as well. Also we have a wet EGR (or the area around it). Also, do recomend a dealer part or from another manufacturer to replace this? Any brand in particular you recomend? New to VW's (and diesel). Thanks in advance.
On the 2003 models you have the ALH type engine. Which is set up differently than the one in this video (BEW type). So, on yours It’s just a vacuum pump. Your high pressure fuel pump is located near the front of the engine. It’s driven by the timing belt. You may just need a gasket kit, this is the link www.amazon.com/RKX-Vacuum-Reseal-038145345-rebuild/dp/B01MTVJFXD
But if you want to replace the whole vacuum pump, any brand should do. Dealer may not have it due to how old the vehicle is, but it wouldn’t hurt to check. You can get it at your local parts store or online. Just check the reviews before buying.
On the wet EGR issue, it may be leaking or you may have a loose or dry rotted hose. I would recommend cleaning the area and inspecting it to see where the leak is coming from if you can.
Hope this helps, & Thanks For Watching.

Top two bolts are 20Nm and lower two are 10 Nm on my seat Ibiza very last owner mess it up and there strip the threads and I be getting tip and due to fix it
How did you prime the fuel system. Just installed mine and it doesn’t want to start.
Having to replace the pesky plastic coolant neck flange, some of the plastic cracked loose, gasket not sealing right. Just ordered it from ebay for $23.42 total, shipping from Bronx NY. Annoying plastic parts, Mercy...
Thanks for sharing, good video & haven't even finished watching it yet. Does the BEW engine code correspond w/ certain year models? I've got a 2006 1.9tdi, & it's very similar, but a few things are different. Thanks again, - take care.
Yes depending on if you have a Jetta BEW starts from 04 to 05.5 and new beetle from 04 to 2006
@@AlexTheCarDoctor Okay cool. Did this car fire right up, or did it take any extra cranks/cranking? I saw a broad price $ range for these pumps, where did u buy from? Keep up the good work, - take care man.
@@AlexTheCarDoctor Hey Alex, do u remember where u got the fuel pump & about how much $ it was? Thanks.
@@leeisenberg sorry I don’t remember yes that bew is very similar to yours
On this engine model, it don't need like put it on time? 🤔
Is that actually a high-pressure fuel pump as compared to newer vw diesels
Does my 2006 Jetta tdi have a HPFP?
Did you have trouble starting it? Seen others prime the pump before starting the engine
From what I can remember no the Electric fuel pump does a pretty good job of delivering the fuel right away and helping with the prime process
My brake pedal is pretty hard to depress. I checked the back of the vacuum pump and that barb fitting was really loose. Would that pump or loose fitting cause the pedal hard to depress
Yes it will make your brake pedal hard if you are loosing vacuum
@@AlexTheCarDoctor thank you for the quick response. Great tutorial. Not too many mechanics go through the steps you did. 👍🏻
Hi, why does my vw golf5 1.9tdi engine shaking when i turn off the AC
And when I turn it on the shaking just vanished
Alex where did you get the pump at if you can say and the cost
Hey there i do believe I got it from a parts store called World pack that only sells to shops
I forgot the cost
Is this the tamdem pump
Yes the high-pressure fuel pump and the vacuum pump pretty unique little part
I would hate to watch a number 10.
Lol I recently stopped rating jobs it’s really hard to do my skill set is different from everybody else’s LOL. Thanks for watching and the support buddy
