10mm to 11mm VW TDI fuel injection pump swap - Bosch "VE" upgrade on 1.9 ALH Diesel Jetta Golf Bora!

- เผยแพร่เมื่อ 7 ก.ย. 2024
- In this detailed video I remove the 10 millimetre Bosch Rotary VE Injection Pump and replace it with an 11 millimetre pump from an Automatic transmission car. The same process can be used on VW Jetta Bora Golf and other ALH cars like Skoda from 1998 through 2003 or so.
This is part of a series of performance upgrades I plan for the 2003 Volkswagen Jetta (Bora) TDI. The 11mm pump will provide the required increased fuel flow.
This 11mm pump sat in the garage for 5 years and was all gunked up with diesel fuel. Will it come back to life!?
Stay tuned for more videos! Injector nozzles, Bigger turbo, tune, EGR, 3-bar MAP sensor, and so on!
* DISCLAIMER * DO this work at your own risk. You may learn how to change a TDI injection pump from 10mm to 11mm but I do not recommend you try it and do not take any responsibility for your actions. This video is for demonstration purposes only. ENJOY!
414 in the part number is 11mm pump
404 in the part number is 10mm pump

Very clean engine bay. bravo good sir.
Mine is same
03 Golf TDI owner here. Just did my 4th timing belt (400K mi). I dont mess with the cam tool or pulling sprockets anymore. Rather I simply mark the timing belt and three sprockets with a paint marker with the pump pinned. Transfer those marks to the new timing belt and install. Shaves hours from the process.
Interesting. I will try that.
That engine looks brand new, very nice 🤩
so much easier to work on clean engines. especially when dealing with sensitive parts like injection pumps.
I have an ALH with a leak at the lower seal of the injection pump. I don't have the tools to dial in the QA after opening that thing up to change the seal, so I was looking for other options. I was going to inquire about maybe purchasing your old 10mm pump as a replacement, but I now see that I would need to dial in the timing anyway & that also requires tools that I don't have, namely the computer software & connection. I guess that I'll scratch my head a little longer. Nice job by the way. The video was very informative & you have very good work habits.
Jim, thanks that meaningful feedback to me. If you enjoy working on these cars get a basic laptop and a VCDS cable. You will use the laptop anyway and the VCDS is priceless if you want to do anything with VW now and in the future. I think you'll like it.
Find a shop that works on Bosch diesel pumps...they can replace all the seals and get your pump back in shape. Then you reinstall your pump with a fresh timing belt, etc.
Great video! I just got a basket case 2002 Golf TDI back on the road. This video helped a lot!
5:16 lol, you're not supposed to say that word. The mean ladys with short haircuts get mad lol
All joking aside, thank you for actually providing an informative video on the process, I am excited to see the progression of your build as you trek through it! And I will be taking notes the entire time for when I finally ALH swap my lifted Golf!
short haircuts preferably dyed blue or purple.
thanks the injector install video is coming soon but my ZR-1 is taking all my time this summer. I drive the Jetta all winter so may get to it then once the ZR-1 is put away for winter I'll get to it.
I heard of this mod years ago . I appreciate your advice. I been driving vw diesel for a long time ..The na 1.6 then the 1.9 tdi ahu then the last two are the alh ..I done all of my own work on then since i owned them . Pretty reliable and good on fuel .. A few learning experiences along the way..
Great video I tinker around with cars and last year somebody with a 2000 Volkswagen beetle asked me to do the brakes which I did and they stopped by yesterday and wanted me to do the injector pump but after watching a few videos I think it's beyond my skill set and I don't have the special tools.
time consuming and you need a clean quiet indoor place to do it with all the right tools
i have a 01 jetta and did this swap with the pump and injectors . it woke the car up. i can now make tire noise in first and second . :)
This is a fantastic tutorial. Top notch. Making me wonder if you have one for timing belt job as well.. I need to do that also
thanks. no I have not done the timing belt but the concepts in this video pretty much cover it. Stay tuned for the nozzle upgrade!
These little motors are great. If I ever get a Jimny/Samarai I'll put this motor in it.
They are incredible. I drive it in traffic and it can keep up with modern cars in a very busy city. Best 90hp I’ve ever seen
thx helped me alot hope the car starts tomorrow. changed the pump head from a 10mm to a 11mm
Great video. Subbed for the TDI content. I own the same car same year
I have the new nozzles. Still trying to find time for a nozzle video, then a tune video. Soon…
hawt damn that engine bay is clean
Hey buddy how are ya? Great video thank you for sharing!! I did notice a lot of oil grime in the flutter valve housing, I’m guessing that’s from the valve cover pcv system. It needs a puke tank or puck to prevent clogging? I hope to be able to do this when I get a ALH for my Jeep swap. Thanks again I’m learning so much from your channel!
nozzle upgrade and stage 3 tune video is in editing now, stay tuned.
@@gregs_garage right on buddy can’t wait!! Thanks again!
Order a rebuilt or performance one from Giles in Canada. He's the go to guy!
28:30 drill a hole in the plastic backing cover and knock the pulley off
It’s so clean

The glow plugs are just to heat the coolant. Don’t matter which connection goes where
good point. I didn't know. I always put things back exactly how they came apart
@@gregs_garage yes me too but in this case it’s just a technicality. I’m sure they are plug in randomly when they were build
Easier to trace wires and check continuity if there’s ever an issue. I think marking things like that is a good practice
18:47 . you didnt check the timing with trying to pin it ?
Oh my god how is your engine bay that clean I feel like I clean mine aggressively once a week and can’t get it that clean
That car is so clean sheesh need me one of those
Everyone needs a TDI. More vids coming on this car
I just did an 11mm swap and made sure everything was lined up.. still no fire
My TDI 2000 Jetta. Was overheating, and somehow a lot of pressure and the cooling lines. I have the motor all apart, and I can’t find anything wrong. I’m redoing the timing belt water pump. And I have a lot of extra parts from two other cars. I am changing the head just in case it was the head. I’m doing new head gasket to hopefully that will solve the problem.
37:00 . hook a funnel to the input of the pump . its easier
all good ideas. Shows there are different ways of doing things.
This might be a noob question but isnt changing to a bigger plunger just the same as increasing fuel supply on the max power fuel screw? For exemple, a 10mm with increased fuel screw would deliver the same fuel as 11mm with stock fuel screw no? Thanks
not sure. But if it were that simple, I doubt the 11mm upgrade would be recommended. Regardless I think the 10mm is fine unless you really modify heavily.
I'm struggling with my one jetta 1,9 tdi is cutting when I'm driving please help i don't mind even to give someone to check for me
Hello Greg. Should i be hearing the turbo on the TDI Jetta? Mine is making it sound is that normal?
How do I get a hold of you?
I’m just east of Calgary.
two rotation of engine carry out by crankshaft pully not by camshaft sprocket !!!
preferably. But the cam pulley is easier and if you're careful I don't think it matters.
@@gregs_garage you can easily lift the car on jackstands ,put the transmission in 5th gear and spin the passenger side wheel to rotate the crankshaft. But whatever works , it's your car . Good video though
To be fair, you dont HAVE to do an 11mm, you can get by just fine with a 10mm pump and change the fuel settings in VCDS. You can also rebuild a 10mm and make it an 11mm.. Not only does it give more fuel, its under higher pressure and offers better atomization. Without doing injectors and bigger turbo and a proper tune, you are wasting your money
injector nozzles and a tune are coming soon.
@@gregs_garage just stay away from Pete at DBW or Kerma.. there is a boycott of them for poor customer service and theft of deposits ( dbw)
Very interesting video. Can you use this injection 11 mm pump on a 1Z engine?
Yes it can be done. There are articles on this swap you can find with web searching. But I believe it requires some custom fabrication to make it work.
How it called that electric connector of injection pump
I am confused how do you get the timing on the fuel pump correct before putting it in?
watch that part of the video closely.
Looks like you didn't tell about any timing mark on the fuel pump,
What position the pump shaft should be when motor is locked to first cylinder at TDC
Why dont you just turn one front wheel in 5th gear to turn the engine ?
Isn’t a wrench easier?
Great video! It seems I'm lucky i saw this upgrade.
is it possible for me to replace my (132 kw) truck ve pump ,which has the numbers 0 460 426 438 (ve6/12F1200R908-12), with one different 0 460 426 xxx (ve6/12F1200Rxxx) or 0 460 426 xxx (ve6/12F1250Rxxx) or 0 460 426 xxx (ve6/12F1000Rxxx).
All pumps fit the engine without any changes (timing and firing order).
what would be the consequences?
Thank you for considering my question
Hello, can you reuse the old high pressure lines from pump to injectors because on some newer cars they say they are one time use but on these I heard you can what’s the difference?
these are re-used yes. They are simple metal tubes. not sure about newer cars. I only drive old cars.
Thanks. I've learnt a lot from your video. Could you please tell me why I have bubble air in that transparent tube witch is between diesel filter and the pompe?
There are often small amounts of air bubbles in that line. If it is running well don't worry about it.
@@gregs_garage The engine is running well, it sounds normal, but isn't it losing pressure on the system overnight? I guess that's why the engine is harder to start in the morning and because of the spark plugs also ?
How spark plugs are there in a tdi, also that bubble is in the input line, and air should not be there on the high pressure side of the pump till injectors.
God bless the red line
very nice pulley extractor ! where did u find it ?
Metalnerd PN #4001. look it up
Hello
after installing the 11mm pump do you tune the electonic??
Or did you just swap one for the other? thanks
just swap. The pump will work fine. Same as 10mm. When I install larger nozzles, I will get a TUNE
I'm looking to try and pull all the electronics off a tdi and do all mechanical system could you steer me in the right direction. I'm very limited on knowledge. And im turning up short information.
I don't think that's a good idea. The magic of the TDI is in the electronics.
Hi, I am about to swap the pump on my Audi a4 b5. Does the "new" pump have to be coded or just replace and time it?
Replace and time like in the video. Not sure what “coded” means
@@gregs_garage I replaced it and it fired up, however, it takes a few seconds. Also the engine is making quite a racket as if due to fuel starvation. The acceleration at standstil is also kinda erratic. I'm beginning to suspect that the old pump may have not been at fault, or probably the issue is multifaceted.
The main reason for replacing it is that there was a fuel leak but since service kits are nowhere to be found here in Bulgaria for these pumps, I resorted to sourcing a used replacement for like £28...
Wondering what's your opinion on EGR deletes? I've read a lot of conflicting stuff.. some say it shortens the lifespan of the engine and decreases performance, others say a simple delete can subject the engine to more stress and problems other problems...
I was planning to EGR delete when I do the tune. I’d rather have clean air going thru the intake and a cleaner intake area. I can’t think of any reason why EGR removal would harm the engine
It gives better fuel economy while idle. Thats it. The soot and carbon buildup in your intake is bad for the engine. When particles and flakes loosen they go through your combustion chamber and result in excessive wear on your valves, rings and sylinder walls. Better block it. Remember to completely clean your intake in the process to prevent this from happining
Couldn’t you have kept the 10mm pump and put an 11mm head on it to save swapping pumps ? Cheers
Probably. But the 11mm is great especially after it ran for a while. Driving the car right now
You can swap the head for an 11mm but I believe if you pull the head some parts internally fall out of place. I'm not speaking from experience just what I have read ( someone correct me if I'm wrong). So from my understanding if you are swapping just the head you have to be prepared to reassemble the guts of the pump which may be easier or only possible with the unit out of the vehicle.
When I did the head seal on my leaking pump my buddy told me to only back it out enough to get the new "O" ring on otherwise I was in trouble.... nothing I couldn't have handled but a headache for sure
yeah I wouldn't want to be messing around with an head swaps. The pump swap was hard enough! @@sunoclockoneday2576
If you don't mind walk me thru the cost the new or recycled fuel pump $ , lines, injectors $ , and $ new or recycled turbo, perhaps tuning OBS chip what will your cost be just parts, I see you have a lot of time and effort already. I am considering the same with my 2003 TDI, I have all new running gear, tires etc. and would like to keep it as a quick road trip car since it fun to drive and economical.
Maybe like this, although it varies a lot:
$200 used 11mm pump (if lucky)
$300 new nozzles (varies)
$1000 turbo new
$400 tune
not cheap but fun.
Hello,
is there any visual difference between the two pumps?
I have a 06/2003 golf iv, but with the asv engine, I believe it was one of the last engines to be produced.
So, I don't know which pumb I have.
Greetings from Portugal
they look the same
Ve no embolo, a parte de ferro tem um número, 49 é 10MM e 7x (nao me recordo) é 11MM, tens embolos de 12MM também. A bomba nao interessa, pode ser TDI 90cv 110cv n interessa é tudo igual, o que muda é o embolo.
Thanks man!
no problem. I'm doing a video on the nozzle upgrade soon. As soon as the Fisker and the Corvette are running again I am going back to the old TDI which is one of my favorite cars.
25:53 you need the intake tube out of the way
yeah I know. I seem to recall I had trouble accessing the clamps so just left it on.
Good video! Where did you get your vcds?

Hello Greg, I am installing an engine from an automatic trans car into a car with a 5spd. Will the engine run properly being hooked up to a stick shift cars computer or will I have to have a shop re flash the computer. Thanks for any info.
Don't know for sure but I would just try to run it and see what happens.
Take the engine, don’t mess with the harnesses. The blocks are virtually the same, besides extra coolant glow plugs and tcm/ecm/bcm stuff on the auto. You’re not taking that stuff with the engine, the 5 speed has everything in it already
What are the benefits of the 11mm over the 10mm? Is this a mod for more power? I would think that it would not be necessarily an efficiency based mod. ?
increased fuel delivery when the car is modified. For performance. Stock it is not required. When you add larger nozzles / turbo / tune / etc, then increase fuel delivery may be required.
@@gregs_garage got it! so for a daily driver, it may not be the best option.
Hey, is the 11mm a direct bolt on? I heard you have to create a "hybrid" and use the 10mm pump and 11mm head.
11mm is a direct bolt on. Same external dimensions.
@@gregs_garage Awesome! Great video's! Keep up the great work!
@@d.k.nguyen3977 watch for the Bozio nozzle upgrade coming... and then a tune... likely this winter...

Hey man great work i wanted to ask you does this 11mm pump encreases the power if the car by making it faster and i wanted to ask you i have golf 4 1.9tdi 81kw 110ps is my pum 10mm or 11mm
It can potentially make the car faster if it needs more fuel. Manual trans is 10mm. Auto is 11mm. In N. America anyway.
How can you differentiate 10mm from 11mm

What about the agr? Could K do this on that engine?
yes I will be doing the EGR delete on this car soon. I will do a video.
Pls is any risk if we wash all engine bay ???
diesels are pretty good with washing engine bay. Don't spray alternator.
What is the benefit with 11 mm instead of 10 mm ?
will flow more fuel in a modified engine. Larger nozzles and more boost.
Does this work on a 1.9tdi AFN also?
I'm really not sure. Those early motors are a bit of a mystery. Unlikely to see the performance opportunities of the ALH.
