bosch vp30 vp44 transistor replacement 

Super like. I heard the major failure of these pumps is soldering in the board. Upgrading the heat sink to 60/40 seems like a great idea that could not be viable for mass production but would advantageous for performance and biofuel applications. Thank you!

Good video but more detail about where to solder wires to required . Thanks .

Olá, excelente demonstração. Uma questão: o sintoma desta avaria pode ser o motor desligar quando está quente e só voltar a ligar quando arrefece? O carro também tem sempre dificuldade em pegar (gira o motor de aranque muitas vezes até pegar). Obrigado

Hello, my father bought a ford focus mk1 1.8 TDDI less than a week ago, it ran perfectly but now it won't start. The engine cranks but no start. We paid it with our last money and now we're in a very bad situation. The mechanic insists that the pump has failed and needs to be replaced entirely which would cost something like 1500€, and he's saying that we should scrap the car. This is a very lazy mechanic and is very ignorant about electronics, so i want to ask if this could solve the problem? I already got experience with microsoldering because i repair phones and computers so i'm thinking i should try this as a last resort. Do you think this could solve the problem? I just want to help my family

mate, great video and you have a really calming voice lol.. BUT.. it's orientated the wrong way round! You've got it so you can see the transistor clearly but the way the camera points at it, part of the pump casing is blocking the view of the transistor - and soldering points. But thank you for the video anyway, just your replies to comments below have given me hope that i can fix my van.

Thanks for the vedio please what is the specifacation of the transistor?. My car has been down for almost a year and Injection pump is the problem.

Well even with teh finest tip, lowest heat setting, aluflux... the small contact on my circuit board decided to burn off. I'm now screwed. Don't suppose you have a spare one for a VP30?

Tenho um 320 136cv que a bomba nao tem presao suficiente para fazer o carro pegar .. pode ser a parte electronica como mostr no video ?

Bonjour, excellent boulot 👍 petite question concernant le montage du transistor utiliser vous utilisez un iRlr2905ou irlr2905z et est-ce qu'il y a une importance entre ses deux transistor ? Merci

I have an issue with my vp44, when i put 12v straight to it the truck turns on with the ecm disconnected, so when i connect the ecm truck won't start.. any clue?? Thanks

Hi! I used your video to fix the.problem because it is the most complex. I did not measure the connector at points six and seven before starting. I did everything exactly as you did in the video. Then it occurred to me to measure the aforementioned 2 points of the connector. The result is 98 ohms. This is very low, so psg is short circuited. Can this be improved somehow? Before the repair, when the car stalled, I got the following error codes: p0100, p1664, P1564, P1608, p0335, p1246. It's all at the same time. Can it be repaired in some way or does it need to be replaced?

why not reconnect the broken connection. can you explain?

Were do I buy the transistor to fix that the part number or web site

Hi how many ohms is the resistor soldered to?

Nice explanation but you could have had the camera at better angle

Hi how did you know that the transisor was the problem?

What type of electrical cable did u use

Hello , vp30 and vp44 have the same pump control unit ? Can I purchase an Audi A6 pump control unit to repair a Ford Focus 1.8 tddi ? Looks like the same part . . . Thank you .

Thanks for the guidance, what type of solder did you use for this?

Thanks for the video!! I have a question...I tried to repair my pump and after giving ignition, I noticed some smoke coming from one of the soldering pads(the tiny one of the right). The car of course doesn't run and I checked all the connections but seems to be right. Any tip?

Maybe edit the video showing the contacts on the pump PCB and witch transistors legs go said points

Can you put hot glue as like a holder for the wires in case the solder heats up and it gets loose? Kinda like the silicone that was already there

Good a question, if the vp30-44 is not coded with the car, when turning the ignition key but without starting, would voltage also reach the flow valve, or would no voltage come out of the psg5? I have a pump that I bought from scrap, without coding, I have connected it to the car, and I contacted, to see if the voltage reached the flow valve, but no voltage arrived. So I don't know if it is because it is not encoded, or it is also broken.

Buenos dias amigo el transistor es el IRLR2905? yo lo he instalado el carro prende pero al rato vuelve y le da la misma falla quema el transistor tu me podrias decir en que puedo estar fallando?

nice

what happened to it?

What about the two wires n the side are they meant to be insulated ?

What is the problem before?rhanks.

Que video has echo, si no se ve nada

Where can I buy one of those transistors?

I have a problem with my Ford Focus TDDI 1.8 66kw. After some time of driving (30min) it "slows down". It cant acceleration as before. In diagnostic it says something about bosch pump error, so is it possible to fix it like you show in video by replacing transistor only?

Thanks for the guidance, can i do a multimeter test and how much ohm should it be?

Today I inserted a 12V 55W bulb, and when I start it, it blinks and the voltage fluctuates between 12.6V and 7.9V. But I don’t understand why the valve does not work when the valve is connected. Maybe a transistor? although if it was a transistor it shouldn't have blinked one light, right? On the other hand, when I connect the valve together with the bulb, there the bulb no longer blinks if I start. IF I disconnect the solenoid and leave only the bulb, it does blink. This could be that the transistor is without power perhaps? ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE--r797kBsHXA.html
