Technical Punto evo 1.3 diesel multijet
Others here may give better advice, however I totally stripped and rebuilt the injectors on my daughters 06 Grande Punto 1.3 Multijet with no consideration to order of fitting and I believe from memory one even came s/h from eBay!I have taking out fuel injectors to clean them but I forgot which cylinder they belong to ,
Any way to find out using the code printed on them or from car ecu ?
3 have same flow rate and one higher !
Thank you
The car started and ran fine, passed four Mots before finally selling. Obviously in an ideal World coding to ECU could arguably balance them slightly better, but from personal experience you will probably not notice the difference if you do.
My only thought is you mention one has a higher flow rate, was this tested at a diesel specialist and if so what was there advice?
I have done some research on them and those the numbers printed on the 3 has same number and one Is different.
As I said before, try them.
Your chance of finding one with exactly the correct numbers is slim.
Is it possible that odd one is for a different engine altogether and not simply a "fine tuning " coding issue.
Try putting those numbers into a search to see what engines they are used on. I know basically the same injector design was used on several different makes and capacities.
If they were the ones that came out, then personally I would just fit them and see.
Obviously if they are not what was running in the car before then that is different.
You can check on the internet yourself to see which is the correct part number.
What was the issue that needed them coming out?

Those are the ones they came out, the issue was white smoke , raugh idling , tractor sound , smell of diesel , rpm dancing up and down .
Sounds like an EGR issue or maybe very low compression if also hard to start on a cold day.

Used to Start perfectly fine even in cold days
So the reason you removed the injectors was white smoke etc.? Who advised doing that?
If nothing else is wrong, I suggest refitting injectors and when engine is running, hopefully with no error codes, put a can of DPF cleaner in fuel tank and give it a good run of around 30 miles at 2000 to 3000 rpm to see if it is just the DPF needs to clean it's self which if you are living near/in London may not be happening.
If doing the above helps then afterwards change the engine oil and filter as car trying to do the Regen may have put diesel in the engine oil.
Have any error codes been read from cars computer? If so what?
I seem to recall when I had my old early Multijet 1.3 that the injector's serial number is coded into the ECU so if you take them out it will probably expect that injector to go back in the same place. No idea why? maybe the injector has some calibration information inside its own computer that needs to be read by the ECU?
I would put them back in, in what ever order you feel fit and hope for the best, if it works then problem solved but if it doesn't and you get an engine management light or it won't fire up. you're going to need a computer to plug in and code the injectors correctly anyway. its not going to cause any major new issues to just put them in and see if it works.

I agree with @AndyRKett that ideally it makes sense to replace them in correct order.
As far as I know the coding is more of a "fine tuning" of the metering by the injectors and from personal experience of not doing the coding and using an odd injector to make up a set, for all an intents and purposes most people would be hard put to notice the difference in driving with coded or non coded injectors.
