Hy guys! Iknow alot of people ho have many problems with theyr diesel cars like: BMW 2.0d 136hp, audi, opel, ford etc... One of the major problem is BOSCH VP30 VP44 injection pump. The symptoms are:
>the engine stops and don't start
>eraticle idling
>sometime don't start

Well i have the solutions for thi problem. I succesfully repaired about 12-14 pieces of vp44 and i did alot of pictures with explinations and parts you need it to repair this pumps. The pieces costs about 1 eur :)))))
If someone need this infos i will be glad to exchange this infos with another software or infos.

I DON'T SELL!!!! I ONLY EXCHANGE WITH GOOD TIPS!!!

Well I thought that the Defination of Selling was Getting Something . In exchange for something else ...... Money Information , Software .. Whats the difference mate ....This is a forum who's Ethos is ... If you want to share something... Then do it ... No preconditions ...I'll give you if you give me ... Is not how we work here ...

I DO...SELL!!!! BUT GOD FORBID ..NOT FOR MONEY...FOR SOMETHING THAT I CAN GET IN RETURN ..!!![/QUOTE]

Now how does that look to you mate .....About sums it up EH!....:rolleyes:

hmm i repaired one of these today lond as the pump hasent seized just remove ecm open it up and have a look lets just say if you can solder you can fix em

[Meat-Head]

Slighlty confused, but there was a simular thread on here, if this is the same pump on vauxhall vectras?

I do know for a fact it doesn't take long before you smell like a plant fitter.

so the yes or no question, without any silly passwords, is does this information apply to the Ford Focus Diesel as well as the Vauchall Vectra?

Thanks dude.

[thedogzeus]

Hi Guys,

Struggling with a VP-44 pump issue. Ford Transit 2004 2.4 duratorq.

Has no power, sounds like a bang of nails when revving, error code P0148. From reading posts at various forums, looks like the timing solenoid might be the culprit here.

Can any one confirm diagnosis, and any handy tips on replacing would be appreciated !

Ford want $5000+ to replace the whole pump.

Cheers,
Brett

[jp_olli]

I guess these instructions and iformation will help all with Vp44 related issues.

I?ve been studying how to repair the pump edc. Here in Finland we have quite many Opel / Vauxhall enthusiasts struggling with VP44.

To attach the new transistor to the aluminium body I?ve used silver loaded epoxy from RS. It holds well and transfers heat away from the component.

Next week I?m going to test how IRLR2905PBF will work as a replacement part.

Hope that it would work.

EDIT: The silver loaded epoxy also conducts electricity very well when it has dried, so you can use it for bonding the gate and source pins to the pcb.

[pajper]

dragan.pavlovic@rocketmail.com this is all information how to change the broken transistor in
VP44/45 .Can you send me this

[davidmc]

When you change the transistor, will there be any issues regarding reprogramming of the pump ?

[jp_olli]

I?m not quite sure. The goal is that the new transistor would be as similar as possible so injection quantities would be correct.

If that works there is no need to reprogram the edc because usually it is going to the same car as it has been removed from.

And if any issue should come, I just have to study more about reprogramming the edc.

One thing one local diesel workshop has been asking me is, how to reset the memory fields in the edc. Since they can only try to calibrate the new edc four times and it gets locked and usually scrapped.

Don?t know yet... Hopefully there would be a way to do that.

[bojo06]

You can use IPS1011 (http://www.irf.com/product-info/datasheets/data/ips1011.pdf (http://www.irf.com/product-info/datasheets/data/ips1011.pdf)) for test!

Hi to you all. I came across this site by google because I do have problems with my bosch fuel injection system.
I am not sure how it all works on this site yet i do believe to understand that I need to leave a post first before i can download information. I would like to appologise if all of a sudden this message appears all over the site. I am trying not to perform foolish things but since I am not familiair with how things work I am just trying to make the best out of it. It is to my understanding that I will have to wait now for 15 minutes. So here I go hoping it will work.

I have a question regarding VP33. I just saved Focus TDDI from being scraped and apparently someone has fitted a Transit pump (code 0470004012). I was told that it requires 0470004002/0470004007 pump but these are difficult to get and there are many 0470004006 also from Focus.

Can you please tell me if i can use 0470004006 instead of 0470004002/07 and what are the differences between these pumps? (solenoids, electronics etc)

I have spoken to many specialists and some say that I can use them, some that I can't and the main problem is that I have to pay ?150 to remove pump code so that it will work with my car and I don't want to loose it decoding wrong pump.


Many, many thanks for your help.

Hi all ,
today i`ve registered , I see some ppls from here are romanian (like me also) ... they have right , injection pump ecu problem is one mosfet (original code is FDB44n25 ) ... I`ve heard he can be substitute by IRFZ44 / IRFZ44N OR IRF540 OR IRLR2905 ..etc :)

Also I have one vectra B 2.2 dti (vp44 pump) ... same problem , I`ve removed the ECU , I tryed to substitute the 44n25 with the irfz ... but don`t work (low debit) ... anyone can give me a picture how to make the connection with irfz44 ? thanks a lot

yahoo_id:buju_mic

[bujumic]

btw, I have ordered from usa the original part (FDB44n25) about 100 pcs (they don`t offer me option to buy under 100 $1.92 item + shipping) but I will need to wait 2-3 weeks ...

I've just used the IRFZ44N transistor replacement fix. I discovered that one of the the original transistor wires was broken possibly melted. The car started but the Transistor got very hot and then the car cut out. If this drives one of the solenoids could the solenoid be faulty?
I bought a few transistors and I can replace the new one quite easliy. Was over the moon when the car started but now chasing something else.
Fault code 01268 came up and when I cleared that and tried to start again the original 01318 code reappeared. I think it is the solenoid. Can anyone confirm?

Thanks AKTIV but how do you know? The car started which it wouldn't do before and then cut out after about a minute. The wiring still looks to be intact although I shall go back out and have another look.
Do i need to get a good heatsink onto the transistor? Doesn't look as if I could get a good sink onto it unless I mount it externally.

[Bij de Hommel]

I have read somewhere on another forum (do not recall which one I am sorry) that the broken wire on the transistor is a common failure with all these Bosch pumps from before 2003 manufacturing date. It appears that the design of this wire is to short so that after a couple of years it simply brakes of due to expanding and shrinking due to heating and cooling. This has got nothing to do with the solenoid. Yet your solenoid could still be broken but the first reason seems more obvious to me. I hope this helps. I have got the same problem with my Ford focus. It is a stupid costly failure.

[kasp.]

so, the transistor change might or might not work?? is there permanent solution?

[Archibald]

so, the transistor change might or might not work?? is there permanent solution?
Rebuilt? ?500+VAT in UK, or 500Euro on continent.

[Bij de Hommel]

If the information I have seen sofar is correct and the original mosfet has # 44n25 than it is a fet that can dissipate a power of up to or around 300w. The original fet is mounted directly to the pump lid. This way it will loose a lot of its heat. In addition to this the lid is cooled using its own fuel underneath in the housing thus all together a very good cooling is quaranteed.
Fet replacement should work as long as you are able to fix it in such a way that it can loose its heat. Whether the IRFZ44n (power dissipation 94W) is a good replacement I do not know. I also do not know if the way it is shown to rebuild is correct, I have got a lot of questions still myself. Currently I am investigating if IRL 2505 would be better. It has higher current features as own power dissipation (200W) . Anyway no matter what you choose it will at least have to have a proper way of cooling (my modest opnion).

[gthys]

hello,

what kind off software do you use for testing the pump on you testbench ? is it something you sell to ?

[jp_olli]

If the information I have seen sofar is correct and the original mosfet has # 44n25 than it is a fet that can dissipate a power of up to or around 300w. The original fet is mounted directly to the pump lid. This way it will loose a lot of its heat. In addition to this the lid is cooled using its own fuel underneath in the housing thus all together a very good cooling is quaranteed.

As I said previously, use the following product to ensure heat transfer and electrical connection to drain.
RS | Workshop Consumables | Adhesives, Sealants and Tapes | PCB Compounds and Adhesives | Silver Loaded Epoxy Adhesive (http://uk.rs-online.com/web/search/searchBrowseAction.html?method=getProduct&R=1863616)

sorry nooob
help needed please!
been burning my head out trying to sort a wired fault on my focus di 01
I think it's the vp-30 ?????
the car starts fine from cold runs without a prob for 5min after this point the car starts miss firing and cuts out (coil light on)
this is wired part after repated restarts eventully the temp gauge hits the half way mark the car runs fine

[bluen0se9]

have tried getting any fault codes?

[darius89]

Hi, why irfz48 doesnt good ? tatasheet is similar irfz44n ????

[yarecky3]

Does anyone know if there is a change to change a software in the pump. I mean if there is a chance to fit pump from opel to lets say bmw?
I know there are pumps communicating via k-line and via can. A6 is a can and A4 is K-line even with the same engine AKE. For the future is there any chance to adaptate one to another?
PS if someone need I have a complette VP44 for a4 04 180bhp, AKE engine. I got it for allroad but as I was saying a6's have can communication a4 k-line.
Many thanks for interest

Hi
The day before yesterday I have in the garage an Opel Astra G 2.0 DTH engine pump vp44, trouble code 1630, I found and changed the faulty transistor with a new IRFZ44N engine started, going well at idle but is not accelerating more than 1300 rpm.Yesterday an BMW E46 320d she had the same problem the same result .What is wrong?

[yarecky3]

did you use the same transistor before?
in my opinion there is not enough powerfull.
in the morning I'll check my own one and I'll let you know
Cheers

[treo]

Yes I use irfz44n for both pumps,for BMW pump I try with 2 tranzistors from dyferent manufacturer.

[zero_cool]

so, 1630 is wrong mechanics, not electronics!!! For example Opel - code 1631 or 1651 is wrong electronics / code 1630 or 1650 is wrong mechanics, so if you changed tranzistor, you have good elektronics, which you can use on another mechanics...

Before repairing edc unit the motor dont start,after he start and run perfect at idle but dont accelerate more than 1300 rpm, so mechanics is ok.

[zero_cool]

I had this problem,that don?t accelerate more than 1100 rpm, I changed mechanics and all was OK.

is possible, that mechanics damaged electronics, so when you are changed or repaired electronis.... can be, that mechanics is still wrong... (what tranzistor uses?)

Hello everyone, I've only just joined this forum so I hope that you don't mind me getting involved in this long running thread. I've just had to replaced my Vp30 pump on my Rover 45 diesel. I still have the old one, which I'd like to have a go at repairing - hence my interest in this thread.
However, on the subject of reprogramming of the pump. To fix my car I got a pump from another car (I got the garage the fit it though), so I can categorically say that no programming is required. Pump timing is important, though, they should be locked before removal.

can you please give me the documents by email regarding the VP44 electronic device. I need to change the trasistor. my email is ovidiu20012002ro@gmail.com

[newbieboy]

Looking at the faulty VP30 pump that I have off my Rover 45, I thought that I would check the MOSFET mentioned in this thread. I've taken the top off the EDC unit, but I cannot see how you get access to the pcb. There are two t10 screws on the top, which I've removed, but I still can't remove the plastic cover. Any advice please?

[drivergabriel]

try with a cutter... but with take care!!! don-t touch the pcb!!!!!!!!!!!!!!!!!!!!!

[drivergabriel]

look at the pictures:

[dudaso2]

The electronic device from my pump VP44 is broken and I want to ask if you have some informations how to fix the problem. The error is : Fuel Pump Speed/Position Sensor Signal Lost . I saw that many defects are related to transistor. Know how to change transistor ( where is G S and D pins on board ) or how to see if the sensors work ok? I know that Pins 6 and 7 ( FPCM connector ) is for power 6 GND and 7 power 12 V but when the power is on ....I don't see any power signal to sensors terminals and of course the sensors can not return signal . I want to mention that I work in electronics domain and I have all necessary equipment .

[newbieboy]

look at the pictures:

Many thanks for that. I notice that on the first picture it says not to remove the screws on top (the two t10), but on the second and third pictures they are removed. Which is correct? I did remove them on mine, while trying to get to the pcb, would that do any harm?

BTW, I may have located some FDB44N25 mosfets. Not certain yet, but if I get them I might have some to sell. Would anybody here be interested?

[drivergabriel]

i removed that screws for something else... to change that mosfet is not necesarry to remove them.

[assman]

Is there anyway to test solenoid wich is driven by transistor (one hat burns)?? When I measured it with multimeter it gives about 1 ohm resistance. Resistance is same in my other Focus (in diyly use) with vp30 pump.

[ssivov]

password please!

thanks!

[newbieboy]

Well, you can be sure that the solenoid coil is not open-circuit, but not that it doesn't have shorted turns - unless you have a very accurate meter, with a 'divide by' function. If you can remove the solenoid , you could bench test it, by applying a test voltage from a suitable source and checking if it switches - or by measuring the current flow through it.

[nizu]

Does somebody know what component is that,shown on picture.
In my unit all small wires are open from there.

[newbieboy]

It is difficult to see clearly, but it looks like a surface-mounted iintegrated circuit.

Hey guys!
Anyone tried to put the transistor outside EDC to prevent it from overheating? There would be a lot more airflow, on the downside you would need long wires.

You would need to protect the transistor from the harsh environment that it would be subjected to on the outside of the EDC. Far better to bolt it to the inside, using a mica washer and a plastic insulator. Used with silicon grease, this arrangement would use the metal top of the EDC as a very good heat sink.

Not necessarily - I do a fair bit of mechanics, mostly older diesels - -tractors and such like, but there's more n more electronics all the time sooo... Anyway, I needed to post something, and I was just a bit noodled at having to wait (I hate waiting) to get at info. I've read the whole thread now and hopefully have enough info to allow me to attempt to fix my vp44 by soldering in an IRF540... and I WILL come back with my results. Only trouble is, I'm not sure if the locking device on the pump slipped when I removed it, in which case I have lost TDC forever?

Anyhow, good luck to all, and hope I may be of use infuture myself...

Mine is exactly the same, but I've managed to locate some FDB44n25 transistors. The problem now is how best to mount them. The wiring diagram pdf on page 4 of this thread is very useful, but it doesn't suggest the best way to fix the transistor to the pcb to help with heat dissipation. Someone earlier suggested some silver epoxy stuff from RS, but it is over ?40 a pot. Has anyone successfully replaced the FDB44n25 yet, or have any suggestions on the best way to mount it?

[bagoshite]

I would read Aktive 22 's quote next post down from that pdf on page 4 if i were you, then i would read all 14 pages again and concentrate, just like i am trying to do

[newbieboy]

I was told that it's the IRLR2905PBF.

By whom?

Can you please answer my question regarding flux and solder you use? I can't make mine to stick :(

I will use a flux-cored solder. The important thing is to make sure that the surface you want to solder to is thoroughly clean. There are solvents specially to do this, but gentle scraping and roughing should work.

[Archibald]

By people that used it and aparently this is the best one tha can be used. I am not sure that VP30 and VP44 need same transistor.

I will order different flux as mine is a cheap one, mainly used to solder wires.

[newbieboy]

Any updates?

Not from me, I'm afraid. I'm no nearer solving this problem of where to mount the replacement transistor. The silver epoxy already suggested does seem to be the answer, but it's very expensive for a one-off.

[Archibald]

I was thinking if the epoxy is good enough to glue all connections.

[newbieboy]

I was thinking if the epoxy is good enough to glue all connections.

According the the chap earlier in the thread (I think he was from Finland), who recommended the stuff (from RS), yes you could use it to bond the transistor pins to the pcb.

[saltrock]

Trying to solder it in right now using the pics found on this forum - but I cant get the solder to stick on the very small plate where the old mosfet connected. May have to try the 'straight to pins' method also mentioned earlier in the thread, but somone said that does not work, so I'm reluctant to do it.

[Archibald]

Check the resistance between small pad and the pin and you'll find that there's no direct connection between them (some resistance). Both pins have the same resistance so on both there's a connection! I have not seen anyone succeed doing it this way, but I have seen posts that it cam damage the pump ECU.
This small connection is bloody pain and I had the same problem. You have to use a lot of flux and only solder it for a second. I think that excessive heat input damages the connection and the only way to fix it is to use a silver loaded epoxy.

Ah that's a idea, that might not work, can't see it on their website, but B&Q do for ?8 a 'nail varnish size' pot of copper 'paint' the idea is that thick plumbers that have no idea on how to hold a blowtorch, paint this crap on the two copper fittings and ram the two pipes together

Water pressure is 12bar, and (off topic) your gas pipe has to be bonded
to your electric pipe, so does this stuff conduct?

(although dear do) if a thick plumber piped an entire house with this shit
would it pass electrical saftey tests?

Maplin do some 'thermal glue' for glueing heatsink to computer cpu
(don't use it on your computer, shit idea) but might work on this project.

Can't see all this 'heat sink' stuff bing a problem, it currant trasnsitr is 150k old and 8years old!

This is my first post here so hello everyone and thank you for your help. I am from Romania but study in the UK at the moment.
My dad has a Ford Transit 2.0 from 2002. He stopped to get something from a shop and when he tried to start the engine, it wouldn't start. He had no previous problem with the car before and the guys from the Ford dealership say that the pump is faulty. It sounds like a electrical problem to me. The pump is VP-30, code 0470004004. Do you think that changing the transistor would be a good idea?

Thank you,
Alex

are all the fuses ok under the bonnet, esp top left corner of fuseboard to pump supply

[hynix]

Cannot check them as I'm near the van, but the mechanic said that the injection pump is not working at all. It doesn't inject any fuel if I understood him correctly...

[dafdiagnos]

it won't inject if the fuse has blown. it's also worth checking the multiplug on to the back of the pump as the wiring can rub thru or rot thru moisture ingress. is there any communication to the pump if the vehicle is plugged in???

Hello Everyone,

I am new here.
I wondered if any of you have any experience with reflashing the VP44 pump ECU. Apparently there is a software limitation built in by bosch that restricts fuel quantity to about 210bhp in the Audi 2.5 TDI's.
The VP44 on the big Cummins engines are mechanically the same and are up to much highr power levels, but of course we can't just bolt them on an Audi because the engine ECU checks the pump ECU and doesn't recognise it.
But theoretically it should be possible to modify the soft in my opinion.

Just to add my 'half pennth worth'
Although I have not done this project myself, I read that you are all having the same problem with soldering. Now busaman is suggesting aluminum solder. If this is the correct stuff then I'm not surprised that you are having problems. Lead solder or lead free solder is made to join copper & low temperature stuff. If the solder on the components is Aluminum then it wont mix. Quite poss it is a high temp silver solder used. We had some projectors that the lamps were soldered in place & due to the heat I'm sure used silver solder.
Mind you I could be talking out of my ar*e & I'm sure your going to tell me so :)

I don't think so, in fact your post was very helpful. Not sure if your silver solder suggestion is the answer though. I too am having this problem with soldering the connections of this transistor - lead solder is clearly not the correct stuff for the job. What I don't understand, though, is why all those who posted earlier in this thread that they had successfully replaced this faulty transistor, now seem to have gone very quiet on the subject!

[saltrock]

Well, I couldn't get the solder to stick either - just no way, not on the board itself. However, following the suggestion on an earlier post, I soldered to the connections coming in from the side without any problems. Only trouble is, it still don't work! Maybe that method is a crock of shit, or maybe my pump timing slipped when I was removing it... in which case I think I'm stuffed anyway? Does anyone know if the pump timing is recoverable, as there's no woodruff keyway on these things. I'm almost out of motivation on this & thinking of scrapping the damn thing! (Rover 25 TDI)

thanks for the useful information on this thread, folks - I'm an electronics geek so I'll have a play and post anything I find useful.

[bagoshite]

i understand that the pdf wiring diag is wrong
I also found a better solder piont for the source, but the Gate solder piont is just too small and has burnt off my pcb.
Can anybody help me locate a better solder piont for the Gate ???

thanks in adv

[boomer1]

Thanks for all this information on this topic. It really helps me in finding a way to repair my vp44 pump.

THANKS al lot.:wink:

The source is connected to GND.You have here a picture with soldering point for gate.
P.S:sorry for using drivergabrile's photos,but i didn't have any other pictures in this computer.

DONT use this, its no good for electrical work, the flux will rot all the circuits and wires for months afterwards, its corrosive.

You need a high silver content solder to get a good connection on this type of join.

hello,
so wich tranzister beter to use for vp-44.Can any one send me jpg how to replaced it?(i can't see jpg in 4 page).


Thanks

ok i got a budd of mine who is a electronics guy to install the transistor we hooked up the 2 outer wires like in gabriels photos . then the from body to middle pin, on pics we told to cut off middle pin and not use it, we used it john the guy who did it has alot more knowledge than me so i ran with it . this last connection, were they supposed to be to the bottom of transistor or to the lil plate where the wires were before as we hooked these up 2 the middle pin . , my truck is alive again except it has no power untill it hits 2000 rpm . some one help me i know the two connections are good to go but the other ones
:wink:

[cristi_bv]

It's ok,inside the transistor the plate is connected to the middle pin.Don't worry he did a good job!

[croweaglefred]

must be a shitty transistor, what is the best one to use ill get it and use it . my truck is running

Which one did you used?

[josepz]

And what about to change only the electronic module?
If my memmory is right, I think it was 100-150?...maybe less.

I think I can order the new module, but not sure if it will need to be reprogrammed or not...

I have right now an Opel Astra here with the defective pump... if anyone knows how to load the soft into the new module, I could do a try...

Sounds better than the solder method, I don?t like to receive a customer call asking why his car is burning... :rolleyes:
