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.
Greets to you all.....I do not know wich button to select... I will go for PQR

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

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 ...

Also who have problem with injection ecu 1.7 isusu motors from opel/vauxhall ask me

I know what problem they have

thanks guys for the time spent on this thread, it has helped me alot..

**alfini0507** · 28th January, 2010, 10:47 PM

One more member with the same problem. Electronic part of the pump on Vectra B 2.0DI 16v.

PS Am I right when I think that I should write 25 posts just to be able to see pictures and to download instructions for helping solve my problem. Im not so qualified so it should be stupid just to write anything to reach that 25 posts.

Does anyone know what component can be used to substitute the one on the right side of the ECU (viewed with plug to the right).

Help appreciated
