I need to have my injectors reconditioned. But I don't want the added cost of my garage taking out the injectors and putting them back in. Is it as straight forward as it seems and will there be any problems trying to start the car after re fitting. A guide would be handy if anyone has one. Thanks in advance guys. Always very helpful.

What year an engine in your car

Yeah. Sorry forgot that bit. 2008 mk 4. As far as I know there's no coding needed.

They pretty easy to remove 7 Allen key an 13 or 14 spanner I think coding shouldn't be an issue if u getting a diesel specialist to recon them

as long as the injectors go back into their original positions they should not have to be coded back in.

I take that same applies for the Mk3 as well.

Is there any special tools I need for the job as I'm thinking of doing the same?

That applies to the mk 3 and older engines only. There is no specific order in which to put in the injectors on the mk 4. You run the car for 30 mins and let the ecu learn each injector. That much I know but I want to know how to take them out and if there's any problem with putting them back in, i.e. air in the fuel supply?

the job will be easier with a removal socket

as far as i am aware the ecu can not learn injector codes,it only learns and adjusts the pilot pulse for the injectors.

I had a random set of four injectors that were put in like I said and not coded by a garage. Is this a malpractice then? I'm at a loss now. I still have the originals numbered 1-4 as they were taken out and it's those that I will send to get reconditioned.

I have done this job, but the ecu adjusts according to the wear on the injectors and age etc and would need the new injectors programmed in or it will not run well at all

Ok. That does make sense as my replacements don't seem to be running all that well.

My old ones were taken out and numbered 1-4. If I have those reconditioned will they too have to be programmed in or are they good to go?

They will also have to be re programmed, why don't you put the originals back where they were and put some injector cleaner through the system? Or are they that bad?

Well guys.... I rang 2 main Ford Dealers today and they both told me that the 1.8 tdci mk4 mondeo Siemens injectors DO NOT need to he programmed. You learn something new everyday.

Can anyone definitively tell me the procedure for when the injectors are put back in. i.e. Do they need to be primed or does cranking the engine do the trick?

They need be primed with hand pump then possibly crack the nut at the injector while friend is tryin turn engine over

Thanks for the speedy reply. That's what I thought.
