Hi 😊 my problem is it takes a long time to start hot while starting in the morning is normal, the car is e60 520i, do you think the injector cleaner solves the problem or is there another reason for it
Hi Cosmin ! Great video you have a new subscribe ! I suffered from 2AAF (Fuel pump plausability) and 30DA (NOx sensor) + engine vibration at idle/cruising speed/accelerating. tried swapping fuel pump but it did not work (LPFP). used INPA and realized my LPFP is only 4.2 bar instead of 5 (fluctuating a lot in range of 0.2 bars, fuel rail pressure is 98-150 bars only instead of 200. only if I floor peddal it goes all the way to 200 bar (so probably the HPFP is working properly). And only when I clear èrror codes, I get misfires in bank 2. I now think one or both inkectors in bank 2 is leaking. does it all add up you think ?
Hi! Thank you for subscribing! 🙂 I'm not a mechanic. I just like to learn new things and fix my own stuff. I suggest you read on bimmerprofs page. There's a lot of good info there and i think also on fuel pump and pressure and all that stuff. That's where i also learned about injectors. I don't think lfp would be low because of leaky injectors. But if the lpfp cannot provide proper pressure that would be an issue indeed. Search on the site i mentioned. It will help you 🙂

Hi, super interesting video. i may be facing the same issues on the 2 liter version of the N43 engine but im relatively new to doing stuff on cars myself. Thats why im wondering what app you are using in the end of your video to read all the parameters ?
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.
@@CosminRotaru I have similiar issue. 0 missfire, but my fuel rail pressure drops after turning off the car. I am worrying about my injectors. I don't have more issue excpect this above.
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.
@@nikitasadovoy5082 hi. I have replaced all 4 injectors. If you buy new you will not find anything but index 11. I would not bother buying second hand.
@@CosminRotaru What if you change only those that are bad? if 2 will be 3 revisions and 2 new ones will be 11 revisions. Is it possible to use injectors of different revisions?
@@nikitasadovoy5082you can give it a try. I did and it did not work for me. Not because you cannot mix revisions but because i had no way to proper test them. The ones that i hoped they are ok (as they were not leaking) were not good either (maybe clogged or with improper spray pattern). BTW: the old injectors were index 9.
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.
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.
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!

Hi! I'm not a mechanic. Just a hobbyist that likes to maintain his own cars 🙂 If the oil pump is good, new OEM valve, correct oil viscosity... maybe it's not possible to create the pressure because of warn out crankshaft bearings... 🤷♂️
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.
I just can't understand. At my stand, it costs 7-8 US dollars to make such an injector. The test lasts 5 minutes. Click on the nickname, there is a video there. I made them on old stands.
To make them? What do you mean? Maybe to test? There are not many places with test/clean equipment for high pressure injectors. I asked in my area they only do diesel or regular injectors.
@@CosminRotaru Sometimes it works out. But to do this you need to understand what you are doing. I cracked their code three years ago. I had an idea to code them.
