Bosch VP30 VP44 injection pump repair solution

[Jose19]

Have a 2000 frontera 2.2 Dti. stopped suddenly and wont start. Undone one injector pipe and noticed small quantity of fuel being disbursted. Changed cranck sensor and pump (2nd hand) and still same problem. Any ideas?

Hi

It is your first post and you ask already for help! so read this;

After that, change ecu pump and check.

Gabriel's tutorial is ok. I also repaired the pump .... but I used irfz48 are stronger. Some of the repaired work but some have fallen after a little time for various reasons. And frankly I do not like at all .... and not fix even if money is significant.

I have 1999 Astra with broken pump. Will this help me?

[MARICEL.BALAN]

for lupu_sandu: da... cam asta e solutia. si ce mai face car tool asta?

nu reusesc sa vad imaginile alea,am o problema cu o pompa de inj. vp 44 de pe o vectra an 1999

cod P1220 ideea e ca am pus alta pompa cu acelasi
cod si apare tot P1220,am verificat toate tensiunile in mufa
de la pompa conform Tis 2000 si e ok.~~~~este usor dar nu are putere iar pe tester avansul cu pompa veche sta la 2.7 iar cu pompa inlocuita e 1,7 si nu se modifica chiar daca o accelerezi.
cand ajunge la 3000 rot/min se aprinde becul si nu mai are putere
daca o las la relanti se stinge becul si marge normal.dati-mi o solutie .multumesc!

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.

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.

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

Anyone with any luck with a Saab 2.2 TID diesel pump repair with this procedure? Don't feel like wasting thousands of euros if this would work.
