I reckon it should be a set of 4 (1 per injector) 16 digit hex code (as seen in your screenshot of the tool) - On mine, there was a sticker from factory with the codes (the sticker is now long gone though, but I kept a picture…):

As above. On the 2.4, each injector has a code, and it's a 16 digit hex code.
You can find the code for each injector on the top of the plastic electrical connector of the injector, written on 2 lines. Example in pic below. /Mat Click image to enlarge |

Many thanks for your replies. The handwritten codes in the picture are what is written on my injectors. as I have a 10 digit option on The diagnostic tool.any ideas on what I should install as an injector code from my list of handwritten codes?
I just remembered there is a barcode on the injectors as well. Maybe this will give him more codes to choose from the only problem is I need to take the injectors out again again to read the barcode as they are on the inaccessible side.. … |

Your handwritten codes are not valid injector codes for the puma 2.4
As already stated, the only valid injector code format is a 16 digit hex code for the 2.4 Please check this link : https://bellautoservices.co.uk/bas2rrc-hel...ogramming/ /Mat Last edited by MatLandy on 4th Apr 2025 8:22am. Edited 1 time in total |

Ok….so found the correct injector codes right, where you said they would be.
So compared the injector codes to what my diagnostics tool was saying and the codes are identical the only error message I get now is to do a injector learning program when I try to do this I get to the very last stage and the diagnostic tool states a error in communications Tried wiping all of the error codes again and starting the sequence but still get the same message just wondering whether my Icar3 diagnostics tool doesn’t support this operation but it seems a bit weird that as you would think this was a standard function for most diagnostictools? Also, if I try to edit an injector code, I get to the very last stage and again get the loss of communication error. Does anybody have an idea on what I might be doing wrong or what the problem might be? Looking forward to your comments. |

Not sure whether it's the same problem with your diagnostic tool, just sharing what happened to me the last time I tried.
AFAIU, the injector learning sequence is actually performed by the ECU itself, the diagnostic tool just initiates it (if the requirements like engine temperature of 80°C is met) Once started, the ECU will do all sort of adjustments for several minutes, you'll hear the engine tone changing while it runs. So, long story short, the last time I ran the procedure a couple of weeks ago using my Nanocom, I had a communication error as well as soon as the procedure started, but then I left it running all by itself until completion. “A Land Rover immobilized is a moral defeat for the driver and bad publicity for the vehicle, […] it's up to you to do justice to your Land Rover!” - Land Rover Driving Technique. -- 2009 2.4 Puma Defender 90 SW 1979 Land Rover Series 3 88" |

Nowadays, with modern test benches you can get new codes adjusted to the degree of wear of the injectors. However, I am not sure if it is worth to do it on older EuroIV systems. Puma 110" SW

So my diagnostic tool doesn’t seem to even trigger the self test still keeps coming up with a comms error.
Not sure of next move. Maybe a higher grade tool might be more successful. |

A Nanocom at the latest software build or an IDTool will do it . BUT for any tool the engine needs to be above 75c and below 80c according to Bell Auto service (BAS) a highly respected tuner of defenders.

Thanks IanH,
I’ll try at a higher temperature. And track down a Nanacom unit. Update soon.. |

Yet the Nanocom SW won't start the procedure if the coolant temperature is less than 80°C “A Land Rover immobilized is a moral defeat for the driver and bad publicity for the vehicle, […] it's up to you to do justice to your Land Rover!” - Land Rover Driving Technique. -- 2009 2.4 Puma Defender 90 SW 1979 Land Rover Series 3 88" |

BAS seems to focus on the the IDTool for defenders, so Pete must be referring to the temperature needed for that specific tool. Although in his text he does not state it’s only for the IDTool.
https://bellautoservices.co.uk/bas2rrc-hel...4tdci/vcv/ The Nanocom has had a few issues with pump learn and pilot correction , which hopefully the latest software has corrected and interesting they need the engine above 80C. Have you the latest docs that reference needling to be 80C plus. It would be good to read. |
