Replacing Diesel Injector - HOW MUCH :o
Discussion
How much do reckon replacing a Diesel injector on a 1.6TDCi Focus would cost......?
My Sons car went into "Limp" mode with a DTC code of P1264. Basically needs a new injector. Got a quote from a Ford main dealer.........
£480
Got another quote from local garage....
£360
The injector itself is £194+vat. I takes less that 1hr to fit but then you have to update the ECU with the number stamped on the side of the Injector!!! What the f
k!!!
I could do it myself with a second hand injector for £100 but how do you update the ECU

Hmm, a quick google suggests you can probably get an ELM327 cable from ebay for about £20 and do it yourself with FORScan

Check your exact model of focus, but that seems reasonably straight forward.
What's the worst case? You fail, and have to get a garage to do it anyway. You've lost £20 on a cable.
I'd definitely have a go first. Buy a cable, download FORScan and see if you can read the existing codes out and write them back again. If you can, go buy an injector.

Dont diesels require bleeding the fuel system etc when something is done? Might not be a simple case of "re-assembly is the reverse of removal"I could do it myself with a second hand injector for £100 but how do you update the ECU

That looks like it'll do the job...... where did forscan come from?https://forscan.org/forum/viewtopic.php?t=2

Because these things are so precisely calibrated and need to operate to such fine timing (especially so for common rail diesels) that you need to let the ECU "know" how it's been calibrated. 
Bring back surface carburetors, that's what I say!

https://forscan.org/download.htmlThere's a free version for windows, and a licensed version. I can't tell without having the car plugged in whether you can set injector codes in the free version. Worth a try...
A second hand injector will probably as bad, if not worse than the original...
Replacing them is a really crap job.. Sounds like an easy job on paper, but the lay out of them is rubbish (blame PSA as it is a joint venture with Ford)
They have to be coded, as the coding is the correction factor for the PCM to operate the injector correctly
After fitment, they also need a drive mode completed a number of times to complete injector learning, otherwise it will smoke and have horrible diesel knock.. (yep even worse than normal)
Expect the other three to fail in short order...

Just resurrecting an old thread here - but relevant to all the info above.
Got P1264 code on mine and nasty misfire.
Went temporarily away and was running on 4 again when cooled down, but on a 2nd test run, misfire and code returned.
1. On the 8V version of these 1.6 motors, changing the injector was easy. 1 bolt, 1 fuel union and 1 return hose. Plus moving a couple of wires etc out of the way.
2. Injector only needed a light twist to unseat it and it pulled right out.
3. New injector was a Siemens VDO (OEM) from Euro Car Parts - they had stock in the store.
4. New injectors DO need coding - but as above, one of my existing ELM327 leads, plus the free download of forscan was all it took to recode the new injector using the 6 digit code.
5. I then also reset the adaptation for the injectors too.
I found there's not much easily info on these engines - so hopefully the above might be useful if someone is googling this.

Using "forscan" for calibrating, it gives a little diagram for cylinder ordering which shows it in cylinder order. I guess different software could choose to number in firing order, as long as it's consistent to itself. I also cross checked the old injector code with it's apparent location forscan gave me since I had also read as you note on some forums.

It's added value for the dealer I guess......
£50 to plug a computer into the ECU and update a few numbers!!! Modern day highway robbery!
Ok so go buy the computer and the software needed, and the tools needed, and the workshop to do it in. Oh and pay the mechanic, and the book keeper, etc..........£50 to plug a computer into the ECU and update a few numbers!!! Modern day highway robbery!
