Is there a person out there who can answer this question for me?

Is it possible to fit second hand used injectors to a dci engine?
I have been told several different things:

1. secondhand injectors are a straight swap and do not need programing.

2. secondhand injectors will work fine but will need re-programing to the new engine.

3. injectors can only be programed once and so second hand will not work and new must be fitted.

Please can somebody who is in the know advise which of these is correct?

Many thanks :d

In theory replacement injectors should allow the engine to start OK but will need programmed to the ECU.

Refurbished injectors can be programmed to suit different vehicles.

I have on cccasions fitted s/hand injecters to 1.5 dci
renaults sourced here in N/Ireland for £50 each and
worked satisfactory without being coded Hth Regards

Thanks for your replies guys.
I take it then that second hand can be used but are most likely to be re-programed unless you are very lucky.

It's not the injectors that need to be reprogrammed,the codes for the injectors need to be entered into the ECU as the flow rates are different on each one.

Having said that,the Renault dCi engines aren't sensitive to having the injectors replaced so using second hand ones in your case will be fine.

My dci got second hand injectors put in! And it runs ok, I'm pretty sure the ECU wasn't reprogrammed but not 100%! I do think my injectors need looked at and this may be why!! :idunno: I had a run of a$$hole mechanics working on my car at one stage :crazy: but I now know better and try to do most of it myself (with a bit of help:d) were possible and renault when I'm really stuck.

As already said secinf hand or new injiectors will allow the engine to run but there is a risk the ECU may go into default mode and whilst drivable it will affect fuel consumption.
The idea of programming is because the flow rate of each injector is sligtly different programming allows the ECU to make adjustments for each individual cylinder. This allows smoother running and smooths out any difference in the power output of the cylinders.

I will have to get mine looked at... but this will be when I have the money to pay Renault Thanks Noel, it helps to make sense of a few problems with my car! :d

You could try phoning around a few diesel specialists - many now have suitable kit for the job. My neighbour had his injectors programmed in for £30 by a local independent diesel expert.

Is the specialist close to Co.down by any chance?? That would just be very convenient... lol :d

My neighbour is away for a few days and I have no means of contacting him but if I remember correctly there is a garage in Netownards who employs an ex-Renault tech and they have Canclip software, etc.

I belive their name to be drautomotive somewhere in the Quarry Heights area of the town. He was referred by another garage so it's possible he may have got trade price.

Thanks again Noel! There is a guy there who is an ex renault tech according to their website blurb!! I may give them a phone later in the week to ask them a few things! Newtownards isn't too far from me though so it would be handy. :d
