Thanks a lot for your videos. After replacing my injectors, coils en bougies on my 320i n43 I got a rough running engine en misfires on cylinder 4. Due your video I coded the new correct values en removed the fault code. Engine runs smooth and no more misfires! Thanks a lot!
Nice vid, had a similar issue on BMW 535I GT 2010 cylinder 1 was misfiring. Owner was told he needs to replace all six nozzles, he asked me to take a look which I did. Took out nozzle out found out it had carbon deposit blocked the tips. Used a pin to clear it, replaced the nozzle and done car ran smooth after wards. It's all about paying attention to details.
This was something new for me . I do a fair amount of injector replacements and coding . I never experienced a misfire due to wrong or not coded injectors . Flow rates off yes but a true misfire never and if I would have that particular car I would do the coding and would be really surprised that it fixed the problem . Great video Luis . I learned something today .(edit) I have had cars that needed to be updated , but this solved rough idling .
I really hope u were here in belgium so i can bring my car to you LOL. Nice video tutorials you have! I'm having a bunch of codes with my 520i e61 with the same engine. and i'm getting tired of fixing one and then another one will pop up😵💫 This is one of the codes i have
Nice find, I wouldn't have thought that those numbers on an injector must be a perfect match with what's recorded in the ECU memory, in order for a motor to run.
what is it ? they tried everyone else first then bring the bodge job for you to put right ? big respect to you for all you do bro should charge double for these jobs
Very good and in depth diagnosis there! ive got a 325i that has rough cold starts, cylinders 5 and 6 always run rough on cold starts, misfire counters go up by allot but it doesnt illuminate the cel, will be pulling my injectors out to see if they are leaking, although spark plugs are always very dry and no smell of fuel, injectors are the index 11 ones, ive changed everything, spark plugs, coils, vanos solenoids and all o2 sensors, no change haha, my final conclusion are the injectors but they are coded correctly... im thinking that since cyls 5 and 6 run the hottest, my seals have gone, if not then il leak check them just to be sure, if not then i guess il just have to cry myself to sleep. 😀
@@LMAutoRepairs well... today was the day when I finally got all the seals and decoupling rings, and i took the injectors out, only to find them covered in oil as a few years back i had a rocker cover gasket leak, and... absolutely no decoupling rings in all injectors! The csr had the injectors replaced to index 11 under warranty, whoever did it were utter donkeys! Cleaned everything out replaced the teflon seals and decoupling rings on bank 2 and jeez she runs like never before! I think what happened is that there was no seal for the injector bore, the oil slowly ate away the teflon seal and on cold starts it had compression loss, cylinders 5 and 6 being the hottest ones must have accelerated the process as other cylinders ran fine, ish... but yeah problem solved! Ordered three more to do bank one and she should be sorted fully, only took a year to get to the bottom of the issue.
Thanks for a really informative video. I've had my BMW E90 318i N43 since 2016 at 35k miles (now 130k) and never had injector issue previously. I now have these fault codes with the car barely idling and just stalling and engine light on: P311B 2E32 fuel injector, cylinder 3, activation 30AE fuel injector, cylinder 3, activation I guess all this points to a leaky fuel injector and fouling of the spark plug, but interested you mention the electrical connections to the injector should be checked too. Is it Ok to pull and replace injectors like this without worrying about the seals?
Probably had an engine change? Like the Jag X-type diesel you did a few years ago. Had another engine fitted but the injectors values werent entered into the ECU
Hi there , A quick question as you might be able to help me!😊 , I have a misfire on cyl2 , tried to see my injectors value and compare them like you did above but noticed that they are all 00000 , went and get them with a camera so I can code them again (I use autel) but it will not let me ( give error on all 4) please let me know if you even encounter this ! Ps :cylinder no 2 has index 11 others have index 8 , thank you .
Hi Never had issues coding those injectors... Might not be a must, must I would get all the injectors with the same index... Have you checked compression? 👍👍👍
@@LMAutoRepairs thank you for your quick reply appreciated, I did the compression test has same values on cylinder 1 and cylinder 2 ( 225 ) seem to be ok..I am going to try tomorrow to code only the 3 index 8 at a time rather than all 4 .. I let you know how it goes . Thank you 🤞
@@LMAutoRepairs hi there , a quick update , I did manage to change the flow ratio all good on all now but the issue continues :( no leaking injectors , change coil pack and spark plugs! Noticed today the Nox sensor not present? It does run very rich as well 23mpg combined. Oxygen sensors seem to be ok equal value on both . I have notice mixture 2 adaptation is -26 ,although I did get few code yesterday after 1 hour of running (002C28, 002C7F) by the way where you based ? Maybe I could bring it to you to have a 👀 . Thanks 🙏
Hi LM Auto Repairs, I have a question. I have the 120i E87 with 170 HP and a problem. Sometimes the whole car jerks, but only when it's warm. If I then increase the revs to 3000 rpm at idle, the error disappears, but only sometimes. The fault memory is empty and the spark plugs, ignition coils have already been replaced on all 4 cylinders. According to the workshop, the injectors are also running well. Maybe you know what the problem might be.
Hi Lewis I was wondering if you have any plans to build a diy pulse sensor or purchase one from Rotkee to use with a scope for missfire finding or confirmation? The cylinder stroke overlays are very handy as well.
Hi My rail pressure is all the time over 2'000 Bar. Dosent go down when ideling. The car uses to much fuel and make white smoke, smells much petrol. What could be the problem?
I need you please. My car is e82, 2013 plate, 2.0 petrol. Have all valves on engine new, new spark plugs, new coils, new chain. Car is still missfires, “mechanic” is sayings that in time injectors will learn again to work fine but after 1 week of driving car is still showing engine light on after 20 minutes of driving. Where are based if thing that you can help me. Thank you
Luis, the unbutcher! Always fixing other people sh*t shows. Off topic: topdon as a new scan lineup that seems very promising and the price seems to be good so far. Was the artipad a good experience?
@@LMAutoRepairs you are lucky. I have exactly the same code the same problem. I changed the 4 injectors with index 11. With 4 coils 4 spark plug. Ecu new 81.2 . First day car running smoothly. After driving 30km like i didn't do nothing same problem same code . Its make me crazy. !!!! Any idea ? Maf sensor map sensor new . All cables and connectors ok . 2 venus valve changed. 🤯

well done, bit of a tricky one if you don't know that the injector values need to be in the ecu, it won't catch you out next time I know.
No it won't...😊

Ideally you change the seals, but to test you can definitely do it, once you find the problem, you can then replace all the seals...
