    Injector readings are as so...

    Hi guys

    So after posting here asking if anyone had a mongoose cable and software I could borrow a gentleman named ianhayter from the forum was kind enough to lend a hand and let me borrow his cable and laptop.

    I plugged it in did live readings of injectors and this was the readings

    Injector 1 = 1.4k
    Injector 2 = 1.33k
    Injector 3 = 1.16k
    Injector 4 = 606
    Injector 5 = 1.02k
    Injector 6 = 1.4k



    I'm assuming injector 4 is the culprit? Also it listed them from top to bottom 1 to 6 I guess I need to work out which one is no 4..also is it because of no 4 being low others are high and that's where the over fueling issue is at idle? Or is no 4 good and the rest are fubard? 😥😥😥😥.. When I accelerate all level out to 1k..

    Any input guys?

    Kind regards
    AF

    Hold on a minute bud.

    I've just checked out a couple of videos on injector offsets and it's not an adjustment.

    Each injector has its offset value printed on it.

    And that is the value you need to enter.

    The injector must be clean and performing correctly for this offset value to be correct of course.

    I am not knowledgeable in this area so if anyone else knows for sure please give us the gen.

    There's a cylinder numbering thread in our S Type Stickies subforum bud.

    Bank 1 is the right-hand bank looking at the engine from in front of the car, cylinders 1, 3 and 5 from front to back, and cylinders 2, 4 and 6 on the left hand bank from front to back.

    But get the diagram from the thread, the numbering was changed!

    Hi jim

    I believe after doing some research injectors when car is at temp and at idle should read no higher than 1.4k as 1.4k is maximum trim and no lower than 600. Alot of folks with the Tdv6s readings are around the 800 to 1k mark which is good they should all be in the 800 to 1k mark when idle. So either the 600 one is lowering itself to compensate because of the 3 high one's or the others are high because of the faulty 600 one to compensate? I dunno but let's see what other input comes through...did quite abit of reading and the people who had same issue as mine where one was reading quite low and a few were quite high all replaced the higher reading ones and the rest all stabilised and everything balanced out. Also after alot of reading some said injectors are drop ins for the Tdv6 engine and don't need coding but also if you match the injector code to your own when buying new or refurbished it's even more of a bonus no coding is needed they auto adjust the offsets them selves. But again will wait for more input. How have you been and how's life treating you sir?

    Kind regards

    We're fine thanks bud, the weather has been amazingly warm and sunny for this time of year here in Cy even until today, although we've had some very strong destructive winds, very heavy rain and a tornado which damaged many houses in the next village.

    Probably due to my Prado diesel producing lots of Global Warming gases...

    But it'll fix itself soon, nights have been very cold (9°C) for about a week!

    Ok, jokes done...

    I'm wondering now if there are both those injector stamped factory values to set into the ECU/"System" for each injector as the compensation adjustment, plus the feedback values that you are seeing as a check?

    That, 2 sets of values, would make sense if correct.

    Here's what I've referred to:





    And here's that being done on a tool I've just ordered for my A Class Mercedes gearbox fault reset (its splurge says it covers many brands including Jaguar):



    Let's hope someone can shed more light, Andy_K and other members know Landrovers well?

    Hi jim

    Glad all is well and your doing good.. There are some injectors like bosch and a few others that need to be recoded but the siemens ones don't as the ecu adjusts itself. I remember reading injector coding info from a injector coder / refurbisher page and they had listed injectors that do need coding and those that don't and remember very well seeing the Tdv6 siemens vdo didn't and taking a sigh of relief one less headache also read many times on landy forums that I stumbled a cross while doing research where they were changed and they auto adjusted them selves so quite confident that is the case. But will do more research.. Had a few questions and ideas I wanted to put a cross.. firstly I believe we should have a dedicated sdd jlr section for each jag category where all sdd jlr questions are posted and maybe the sdd jlr specialists in us keep an eye on it and reply when they can as they can get lost with the rest of the posts?

    1 where in sdd can I read injector codes? So I can save info as a back up

    2 how do I reset tcm and update the powertrain that it says is available? Also does the 130 sdd come with the calibration files and automatically pick it up before erasing any flash data or it needs to download first? As I believe the newer version doesn't come with files and needs to download the files which I believe it did for someone and messed there gearbox up where it erased first and then went to download only not being able to download because it was offline or something along those lines.

    Hi AF.

    I'm sorry that I can't answer your questions, beyond my knowledge.

    So hopefully others who know will help out.

    I would like to know if SDD/IDS can read and set injector offsets/codes/IQA values as shown in the above videos, as well as read the values that you have read?

    Hi jim

    Please don't be sorry its all good.. Will find out one or the other tomorrow as will be doing some fiddling with it got everything ready.

    A little snippet I took from this post that was made in 2016

    VDO/Siemens Common Rail Injectors Injector’s – Only VW applications at this moment require coding. Typical length is 6 digits and found on the injector head.

    https://www.linkedin.com/pulse/look-...al-vinny-patel

    All my injectors have this code 5U3Q-9K546-AA

    So any injectors that I do buy whether new or refurb I will match that code and drop in there are plenty available but also there plenty more with different codes so I have a feeling that if I buy a same injector with a different code then I might need to let the ecu know that the code of the new injector in that cylinder is so and so I believe but not sure yet.

    Regards

    AKAIK injectors don't require coding.
    I do know Jag and LandRover ones are different (but the engine will run), so yes stick to the correct part number.

    Thank you for the confirmation much appreciated.. Just completed tcm reset... Completed tcm update and powertrain update all went smoothly it cleared all the codes when done... Once completed abs fault restricted mode and no traction were all showing as well as maybe 2 or 3 fault codes logged.... Went to start the car and battery was near flat and wouldn't start even though I had charger plugged in maybe not strong enough.. Got battery on charge now and assuming those faults were logged because of weak battery.. Let's hope so... Will update once battery charged and car is started. If it does 🤣🤣
