Need to get some new diesel injectors for my Mk2 1.6 TDCi Focus. This has the same engine as a bunch of Peugeots, Citroens, Volvos, etc, so there’s lots of parts available. Looking on ebay there are loads of injectors advertised for the 1.6 but with a bunch of different part numbers. Do I need to have exactly the same part number as the one that is on my Ford now? ie 0 445 110 259, or can I get away with a 0 445 110 239 for example?

I think any will do but you may need to get them coded for the ford engines. The peugeot engines don’t (or not on the earlier HDI) but some of the fords need the exact injector parameters putting into the ECU which a specialist would need to do.

tbh I would call either your local bosch centre or someone like Dieselbob who (who refurb injectors for about £80 each).

If you can afford it go for refurbed ones with nice new needles and seats that won’t get have the 1800-3000 rpm tick that you can get on some common rail engines.

Dont know about the Focus, but for the Mondeo the above is true. They need coding. There has to be a forum for the Focus. The forum for the Mondeo became talkford or something like that, so they might have a forum. The Mondeo forum was excellent, some really helpful folk.
The Mondeo ones were about £300 each new when I asked.

Coding is the issue.

And while you are at it replace all of them.

My wife’s Freelander (BMW engine) need 2 doing with 1 on its way out, so the garage (mate of a mate) advised us to do all 4, as the labour was the same.

Makes your eyes water doesnt it! £1200 for 4 sodding injectors! They really do take the….

A customer of mine had a brand new make of refrigerated van, one injector failed and this caused him to loose his entire stock of pies and meat, they gave him a hire van for a few weeks , while they replaced the injector, just the one, as they said its the only one thats failed, he wasnt happy when he found it was a common problem and the others would probably fail as well, last i heard he was trying to get of his frige van for another model.

And people buy diesels for cheap running costs, i.e. good mpg figures.

Until something like this happens…..

And yes, I am guilty of it myself.

I would contact these people /www.pattersondiesel.co.uk we use them a lot for fuel contamination claims at work quick and economical refurbishment.

Best option is to ask a Bosch dealer, as I’m not sure how Bosch part numbers work with part supersessions.

As for coding, it depends on the engine.
I know earlier 1.4s (basically the same engine as the 1.6) didn’t need coding, but I’ve not worked on any Ford/PSA small diesels for a few years.
If you look at the injector, if it has a 8 digit alpha-numeric calibration code on it, then it will need coded.
You might get away without getting it coded, but it can cause rough/lumpy running at certain speeds, and/or flag up another fault code. However, if the cars got a DPF, I’d personally get it coded to maximise the DPF life, as the wrong code could cause the engine to produce more soot, which isn’t good for the DPF.

“Need to get some new diesel injectors….”

maybe, but “some”…. I just wondered if it might be the fuel pump that is on the way out.

Yeah, you’ll absolutely have to get the QR codes for the new injector(s) or else you could get some very rough running. The code gives the ECU the flow corrections required for that particular injector so that a demanded fuel quantity will actually be delivered. The DV6 engine (what you have) also applies small corrections throughout it’s life aa the injector wears and an incorrect QR code can completely bugger these – almost to the point where the engine is indriveable.

David Breaks in Kendal is good bet for diesel diagnostics, problem solving and servicing etc.

There are specialists that can clean , ultrasonic clean, the injectors.
This would mean taking out the old ones and cleaning them, then refitting them so they will be the original and therefore the right ones (if they were the right ones to start with).
How effective the cleaning is, can be variable.
Have a look in the yellow pages for diesel specialists in your area.

if you do take injectors for refurb out make sure you label which cylinder they were in
