    Well I guess 2 hours at 10 Amps or more will take up to 30% out of a fully charged battery.

    Warnings are given.

    But I'm surprised at the high current drawn.

    Hi

    I believe the powertrain Control module took around 15 mins to update as well as the tcm.. Now I'm wondering as the last owner had the dpf deleted and removed so would have had the ecu edited accordingly and with me programming a new pcm would it set it back to vehicle with dpf and now can't see the dpf or read the gasses properly so has the theown up the restricted performance on the dash?

    Also while I did this I thought I'd have a look at injector 4 which was reading 600 and after taking it out I saw the copper seal that is suppose to be sealed against the chamber had about 1mm of carbon built up on it so that carbon would be sitting between the washer and the camper so no seal? Hence low pressure and other injectors high compensating?



    Cleaned it all up stuck new washer and put it all back in and as was expecting to happen 2 of the plastic leakoff connectors broke... Ordered a complete set of metal ones with new tubing... Because of that wasn't able to start or run the car to see if restricted performance and no dsc available goes away..

    Regards

    Good luck finding correct leak off connectors. I really struggled.

    Maybe I found a plastic one in the end but connections at different angles

    Hiya

    I bought this complete set for a 2.7...

    Remember my initial surprise that the injectors came out easily?

    The ones on my Merc needed a slide hammer to remove them, and also needed it to re-insert them fully after cleaning them and replacing the seals before clamping up with the securing bolt.

    A mobile mechie did them for me, 2 of mine were leaking badly and everything under the top engine cover was covered in the thick black tar I mentioned.

    Hi jim

    Yep I do indeed... injector 1 cyl 1...injector 2 cyl 4 and injector 4 cyl 5 all came out quite easily without any major force just twist back and forth and pull at same time...injector 1 and injector 4 both had carbon build up between washer and seating area of injector. Cleaned all 3 up and new washers. Thing is I don't have an black tar like or carbon build up around the outside of the cylinders or any where else so it's been kept in... I have a strong feeling as soon as i connect new leakoff connectors and bolt no 4 down the remainder of injectors will level out and number 4 that was reading 600 will go up because of compression and all will be good but will be changing the remaining 3 washers as well. I got this week to go then from Friday onwards till the 2nd completely free so have plenty time to spend on car without worrying about time.

    This cars been a major learning curve I guess once I'm done with this then it's on to how to strip an engine and a rebuild and by the time I'm done who knows, s type specialist with a dedicated garage for the s types only hey 🤣🤣🤣

    Heheheh...

    Yes that's how we learn, from good and bad experiences.

    So I'm surprised your injectors slide down fully easily, all of mine needed to be slide-hammered down until they fully seated before the mechie bolted it down to crush the copper seal.

    Keeping fingers crossed for yours!

    Could it be the walls of the Chambers still had carbon build up on them? Which were preventing them from sliding down? Mine seem to smoothly slide in like a vaccum. Butter smooth but then I did sand the Chambers and seating area down....

    Had a question for someone who might be able to weigh in on this one.. Is the pcm and ecu the same thing and if so will it hold the dpf info on it?

    Reason I ask is I reprogrammed the tcm and after that I reprogrammed a new pcm aka a powertrain control module not existing even though it was still the old unit. By reprogramming new I'm assuming it wrote the whole thing with new updated file? .... after I was done battery was quite low around 9 to 10v and It finished saying it finished but logged a few faults....i cleared all the fault codes but the dash was still reading no dsc and restricted performance ... Now as my dpf has been removed and based on that it was deleted from the ecu by previous owner I reprogrammed new pcm so would it of written original values over it aka dpf is present and now it can't sense the correct gases or values and is throwing the restricted performance on the dash if I'm assuming the above is correct or could they be because of low battery and once i stick charged battery in and take it for a ride it will sort itself out? Any ideas?

    Sorry AF, but with your choice of wording & grammar, I'm not always sure I'm interpreting your posts as you intend, so apologies if I've misunderstood, but yes, the PCM & ECU are the same thing, & yes, it would hold the necessary files for DPF operation. If you have a new PCM/ECU & programmed it to the car & updated it with SDD, it will be as the factory intended it for your car plus any updates up to the date of your software, so if your car was DPF equipped, it will contain those files. Not sure what you mean by "not existing even though it was still the old unit."?
    Why did you change the PCM? Can you not go back to the original? I would be a bit concerned about the loss of battery voltage while trying to reflash any modules, many have been rendered useless because of this. You need a good supply of power while messing with IDS or SDD, as every time you switch the ignition on & off, there is a large power drain as systems wake up/shut down & the software takes control of things for test/calibration etc.
    None of what you have done here is relevant to your injector issues, what were you trying to achieve? I don't think a drive down the road is going to sort it.

    Hi ow

    Thank you for the detailed and quick response much appreciated. As I type on my my mobile I have very limited viewing of what I have typed so certain things might be out of place... Regarding pcm it was one of the recommended options hence I did it as the gears were holding on too long nothing to do with the injectors and that's a seperate issue.. As to new or existing tcm there were 2 options given on sdd, programme existing or new I chose new after reading someone who had chosen existing and ran into faults.... So based on that I am assuming gni will have to get the dpf delete on the ecu again?
