Same, I have one replaced yesterday for 585£ (price of part same day) in Hungary. Mine has 140k miles so all should be replaced very soon. T_T Info from my mechanic: prices skyrocketed since COVID, and a really good quality aftermarket (Bosch/VDO) part is expected to arrive within half a year for a much better price. I'm trying to get my car working until then.
Hi mate, thanks for sharing the video. Do you think just deleting and resetting the adaptation is enough? Or would I need to take it for the drive sequence you mentioned by bimmer forum? Can you share me the link for that just to have a read through?
Hi! I am not a professional, so i cannot say for sure, but I would find it logical that the ECU will rebuild all those adaptations in time. But it probably takes a lot of time this way. You will find a lot of good information on bimmerprofs.com/
@@CosminRotaru I’ve managed to see bmw instructions on this and when changing/replacing injectors, you only need to carry out injector quantity compensation. Adaptations are not to be deleted for such change. Adaptations are to be reset for things like new ecu or new engine..
@@slengoslengaw8510The ecu will adjust injectors flow through their life. As much as possible. At some point there is no room for adjustments and other adjustments will be made (like long term fuel trims to correct for rich fuel mixture, for example). Then you would have misfires, fuel in oil in case of leaking injectors. That's why i think is not a bad advice to reset adaptations. I guess on their minds bmw think you'd replace injectors proactivity, before they fail and mess up the whole system...
Hi thanks for the video. I have a code for injector / misfire cylinder 3 on my N43 318i and considering steps. BMW dealership quoted £479 + £140 fitting per Index 12 injector, so replacement of all is probably uneconomical. Did replacing all 4 injectors finally resolve your rough running / misfires? I may attempt to remove and clean tips and replace seals, otherwise next replace the faulty injector with used and hope that works. Thanks.
Hi! Yes it did. If your injectors are pre index 11 it might be that you won't get it properly fixed with changing just one injector. But start easy with changing the spark plugs first. You can try swapping around spark plugs/ coils. Even injectors (but you will have to code them as you swap them.
@@CosminRotaru Thanks, yes I should’ve mentioned I have already replaced all coils and plugs with some temporary improvement. More recently I replaced the low pressure fuel sensor, and a faulty NOx sensor with a used part and fault has cleared. The cylinder 3 injector misfire fault is now showing with heavy engine shake and engine light worse than before.
@Telstar_1 i had nox sensor errors as well. But i started with fixing the misfires issue (injectors) suspecting that improper burning might have fouled the sensor. I guess i was right as the nox sensor is no longer complaining.
Hello, Thanks for great video! What do you think about the symptoms on my N43 engine: - Car is shacking at cold start (ambiant temperature in my garage is 15C so quite not cold) - Motor goes up to 1100tr/min for a few seconds then drop to 680tr/min or so - Shacking diminishes when driving then goes stronger at idle (red lights) - Same shacking on P R an D. Seems sometimes a little worse on R. - After shifting to D, when releasing the brake, at cold start, car almost "jumps" instead of being smoothly mooving forward - When car is warm, car seems way more stable - Occasionnal rough start when warm Did you have something like this?
Maybe you got the misfires just because the coils - but you might need to change the spark plugs as well as they might be dirty from all the misfires. Hopefully it is not the injectors - common issue on these engines. If you know they haven't been change ever, you should probably change them. They had 11 iterations (updates) on these injectors. The last one ("index 11") are from 2014 i think.
How is your engine running now? You get a lot more detail of what's happening with INPA. Is your NOx system working ok? Do you know if your car goes into Stratified Charge Mode? This mode is essential if you want the injectors to adapt properly.
Hi! Yes, the engine runs normal now (with no misfires). It does goes in stratified mode. I can also see that it goes into desulfuration on the highway - which it wouldn't do if all stars are not aligned. :) I still have negative long fuel trims (especially at idle) which I am trying to figure out why (I am thinking temperature sensors, PCV, Vanos). Fuel pressure (high side) still drops when stoping the engine - but I was told I got it wrong, and this is normal for this engine... And I have an error on the water pump (miscommunication or something like that). You cannot get bored with this car :D
@CosminRotaru Good to hear the misfires have gone. Do you have 0 misfires or do you still get the occasional one? You might be interested in this (from Bimmerprofs): 1. "Remark: In my blog, I have previously mentioned my observations that MSD80/81 (BMW E series) stops updating the individual adaptations of the injectors in idle/Stratified charge if the AC is turned off. I have no information regarding problems/switching off regarding other adaptations (but there is a significant possibility that previously mentioned injector adaptations are not the only ones that are turned off)." 2. "Note: keep the AC always on! Only/if AC is on DME can determine the engine’s mechanical load (alternator and AC pump). Only if AC is on, DME upgrade injectors adaptations in idle/Stratified charge." I don't know if you have INPA but if you go to the above site, you provide the required data from INPA, and these guys will analyse your engine. Nobody knows these engines better than them. It's better you spend 50 Euros on analysis than change parts. :)
@@MartiansChronicle i still get some occasional misfires . The AC-on suggestion i did not know (although i spent a lot of time on bimmerprofs. That is crazy! I shall try it 😁 Thank you!
@@paulmacheso9953 not a misfire error code, but if i look at live that i can see some every once in a while, at start basically. I'm not worrying about those.
The numbers on the injectors represent measured flow that the ecu needs to adjust fuel. You do not need to re-code as long as you put them back in the same place.
Hi! Yes. The test only shows if injectors are leaking. Also the fuel pressure during cranking might not be as high as the pressure provided by the hpfp when the engine is actually running. So s slight leak in this test might be worse when the engine is actually running. Besides leaking an injection might be broken in other ways. It might be clogged or with a bad spraying pattern. So after changing only those two injectors i still had misfires. But i think i have explained this in the video. With the misfires and the fact that the injectors were old anyway (before index 11) I have decided to change them all. My conclusion is that, with these engines, at some point you will have to update to index 11 injectors.
felicitari pentru tutorial !
Never seen em pulled out like that. Clever.
Good Job🎉😊
Thank you! 🙂
one original injector index 11 is 450£ 🙈 i have bmw with 320i same engine and already has issues on 56k miles 😢

Could the reason for still having a drop in pressure be the one-use injector rail that you didnt replace in this video?
Hi! I didn't notice and leak in that area. I also got the info that is normal for the pressure to drop on these high pressure systems .... IDK.
Hello, could rings be compresed with hose clamps? Thanks..
That seems a bit excessive... I've seen people using pen caps. And there's a special tool set from bmw...
@@CosminRotaru Okay thanks would use pen caps.

Hi! Idle control, especially is quite tricky. Everything has to work perfectly for good idle. Do you have access to a diagnostic tool?
@@CosminRotaru yes, I had serious misfire on cylinder 3 and 4.
These misfires disappeared for a few weeks after new coils then came back rapidly

The numbers on the injectors represent measured flow that the ecu needs to adjust fuel. You do not need to re-code as long as you put them back in the same place.
@@CosminRotaru These are two correction factors that have already escaped.
Just a clarification please. You found injectors in cylinders 1 & 3 were leaking, but you seemed to replace and code new injectors at cylinders 1 & 4?
Hi! Yes. The test only shows if injectors are leaking. Also the fuel pressure during cranking might not be as high as the pressure provided by the hpfp when the engine is actually running.

Or maybe i did not understood the question. I have changed ALL injector but did not show the whole process.
