BMW N54 Index 12 Injector Upgrade. DIY Plus Coding

In this video I show you how to change your fuel injectors on your N54 powered BMW. This is my second DIY on this subject, I go more in depth in this DIY and explain why index 12 injectors are the way to go. This is especially true if your N54 is tuned.
I wanted to make this video to clear up any confusion from my original video and also follow the manufacturers recommendations with regards to how to properly perform this procedure.
We are using the INPA software suite to code the injectors.

I don't even own a BMW, but I found your video interesting to watch. Very thorough.

[@kirkaderkderk]

Just wanted to say that thes tutorials have been saving me a lot of headaches! Thanks, man

[@kyleresendes3974]

i have followed ALL of your videos for my maintenance in my N54 and they have gone sooo smoothly... you deserve WAY more subs.. i love you

[@Mike-og1qk]

Re-watching some of your older content and just saw your injector videos back-to-back. You have come a long way from the first video. Keep up the great content.

[@joemonday4422]

Thank you so much Vehicular DIY. My Stealership wants $2,300 for 3 injectors (yes only 3). Thanks to you and your details video that helped me save roughly $1,700. The hardest thing for me through the whole process was getting Inpa installed. Other than that, replacing those injectors was as easy as making instant noodles. Again with your step by step video instructions, I even think my 10 yr old can code those injectors using Inpa. Seriously, I cannot believe how easy the job was but the local BMW Stealership would charge people so much to do. If I can do it anybody can do it. Thank you again Vehicular DIY...!!!

The best 48 minutes of learning here. By far the best BMW E90 resources out here!

[@thai2pro]

Thank you so much for this DIY. I watched it twice, and now I feel like I have enough confidence to DIY. I was about to purchase the bimmergeeks pro tool, but since you went through everything step by step with your laptop you've saved me quite a bit of cash

[@ltdasilva93]

Hey dude, I come back on your videos a lot and appreciate both your workmanship and honesty. Good editing too

[@dougiedickson8221]

I did mine but I bought all new ones, never had a problem since. Thanks for this video it made The Job Easier!

[@CoroDan]

Great video. Researching 135i n54s before purchasing. Wonderful to have this information available.

[@shahnbeast]

Dude thank you so much for this diy, you put a lot of time and effort into making this and it made me more confident that I could tackle this job. Also looking forward to your valve cover gasket video because mine is starting to sweat a little just like yours, keep up the great work man👍🏻

[@UPPERROOMENT]

shahnbeast what’s up are you having smoking issues from the valve cover gasket yet?

[@jz7006]

Your videos are a god send! I am very very green to bmw maintenance and you make it straightforward and informative. The fact you lost each tool as you use it is what sold me.

[@jacobduenez6489]

Was just In Houston the other day I'll be in Texas for a little bit before I leave the US. Good work really helped out I bought an n54 that's basically been sitting for a while at 30k miles and been replacing a whole lot of parts will most likely be doing the injectors in a year when I come back

[@vtmegrad98]

I really enjoy that your video is paced well and in focus, so all the information you're giving is easier to process. thanks.

[@bereal8434]

Well done, very clear and straight forward.just bought coil packs,plugs and new injectors for my 135i and will use this as my reference..appreciate all the time and insight you have provided.thanks

[@passingasgarage2375]

Well done. I had a misfire on my 535xi, 2011 and it was cylinder #5 and after thinking it was a coil and replacing the coils nothing changed. Plugs were also changed so time to do the injectors.!! I found this video gives me the extra confidence to do it the right way. Thanks Again

[@e46m54nissansr20937]

This was very satisfying and informative to watch. Index 12s on the way. Cant wait

[@Pe3Cee]

Wow 3 years already since installing those cheap injectors. I still remember asking you how reliable they were. Definitely served you well considering the performance. Another great vid, extremely helpful. Decided to keep my 335i and put up with having an E92 with 2 young children. So good excuse to start tinkering with it again :)

[@VehicularDIY]

Yeah I can hardly believe it myself. Nice, good decision. It would be hard to part with this car, I've gotten so used to the torque. Worst case you could always switch it for an E90 :)

[@Pe3Cee]

Funny you mention E90, I was looking around for one to do just that. But they’re hard to come by here in the UK, and part of me doesn’t want to switch to another n54 with perhaps higher mileage etc. Mine’s on 81k atm, and the few that have come up for sale are a lot more. I would love to have one with all the optional extras like yours though haha

[@VehicularDIY]

Yeah and you can't beat the look of the coupe vs the sedan. I always loved the way the coupe looks but was never a fan of the sedan but bought it out of necessity. It makes for a great sleeper though haha.

[@Lostinthecameraroll]

Great video, had similar codes coming up on my e92 335i. Thanks for showing how to properly code the new injectors. Much appreciated!

[@TurboCarSlut]

Just performed last night.....the pick tool trick was a no go in my case. Literally had to tie nylon rope around the old injectors and use a mallet as a weight (like a pulley tool). They were IN THERE!!!!!!!!!!!!! Thanks for the video. Oh...I used the icarscan x431 tool to code my DME for the new injectors.

[@mattwardpictures]

46:13 - "Just a quick acceleration here..." Hearing the engine make *those* noises (not to mention the kinetic rewards you're getting from behind the wheel) makes me understand why N54-powered BMW enthusiasts put so much effort into keeping these wonderful but flawed vehicles in shape. Most buyers of domestic or Japanese makes can't begin to understand this.

[@bwnwilliam465]

Thanks for this video brother. Made my injector code a breeze. 👍🏻

[@bluearcherx]

"This is an index 7" ... and this is when I started crying.

[@daking8282]

Very nice video , you explained exactly what i was looking for unlike many videos on youtube they skip a lot of important things , many thanks for your video it was really helpful

[@chilledchadilss4070]

Keep coming back to your vids. great content, saved me so much $$

[@Blizzle502]

Very informative with so much attention to detail. Absolutely the best diy channel for this platform or similar. Much mahalo brother. Keep up the great work

[@1pjodan]

Just done injector 3, thanks for your help.

[@ariman60]

Always so wonderful DIYs you made and I changed my Injectors today, last part number was 079 and dealer told me they newest dealers Injectors. I hope I have now the newest ones on my engine. I followed your Diys and get work done easily and I also use impa for coding that was super easy as you told and showed to people how to do it! Thanks so much so many DIYs that you have done for helping people out to get the job done in this hard engine. What you think do I have the latest version of Injectors? Changing oil I never thought about that but you are right, my engine my Injectors have done 211000 km so long it was time to change them now, I need to make oil change almost directly if I believe in you. thanks to share all this knowledge with us! Great job with this cool car what needs always some services!

[@dougiedickson8221]

Fantastic video covers it all And explains it all. I'm going to do my 3litre e61 now!

[@jared_grey]

Awesome video. Thanks for making it. Gonna tackle this DIY soon.

[@MrKillerhaze]

Great DYI man you are the best!!! Will try this myself when the time comes.

[@annoyedby922]

I clocked your 0-60 time at 4.82 seconds!. nice :)

[@VehicularDIY]

Haha not bad, maybe I should try brake torqueing it and turning traction completely off to see if I can bring that number down.

[@peterclark2618]

Thank you so much for posting this. It is such a help to us lesser mechanically minded folk who would like to be able to do this themselves (ike me).

[@MrBatu676767]

most exciting moment in the whole video 40:16 i was so happy when the engine stopped running roghly

[@raykhan786]

Thank you!!! This was super informative.

[@MrCougar1825]

thank you will be saving this video to do it m,y self when the time comes you saved me alot of money

[@Nico_335i_DCT]

Hi, this week my injector nr 5 gave up. 6 Index 5 on only 56k miles, but almost 13 yo. Because of lack of money at this time, I decided to buy index 9 in Germany($800), on new piezo's and have tested on CarbonZapp equipment. Maybe these last 2 years or so. After that period the absurd index 12 prices will probably cool down. Today I went to the dealership to buy 6 decouplers and the parts guy told me BMW has 15.000 index12 injectors in backorder. In Europe, these index 12 will go for $500 at the moment. Crazy! Dutch regards, Nico.

[@sharonwilliams9777]

fantastic vid simple but so easy to follow I suspose this would be the same on my 118d m sport

[@prembabu5977]

This is amazing bro . Very inspired to give it a shot .

[@krzysztofkowalski6653]

thank you for this video man, this and the other when you show how to replace the injectors, i just got 3 new from bmw for my n53 engine, so version 11 and they came with this compressor piece as well, I know that there is a special tool to be putting in those seals, though I would never think that they would actually leave that piece over there, I suppose it makes sense now that you have to replace the seal everytime you remove the injector, as it may start to expand straight away maybe

[@bikdesign1561]

Hi. To ask about your n53. Which version is the best for n53 ..tq

[@Romski1978]

Great video, i just having issues with my 530d f10 beema, she shaking when is cold start so I guess is injectors problem. But I guess I will never do this on my own. But is nice to watch that can be done.

[@alquehenwebb7349]

Thanks again for your video very helpful

[@basedtiger8984]

Good precise DIY 👍

[@osagyefoghanaba]

Awesome...Thank you for blessing us with this video! Very insightful.

[@gtsleeper89]

Nice video! For releasing the fuel pressure I would recommend disconnecting the fuel pump power plug under the back seat or removing the fuse behind the glovebox. Then just crank the car for a second and it will release the pressure in the hard lines. Obviously the car won’t start since the low pressure pump is not feeding the high pressure pump. Also then you will only have a small amount of fuel come out of the lines when you take them off. Have done this a couple times on my 135i to do low pressure sensor fuel sensor and index 12 injectors.

[@cliftonjackson441]

gtsleeper89 I did that when I changed the injectors in my genesis coupe. Pulled the fuse that is

[@fast4d1]

I rather not spray down my cylinders with raw fuel

[@nadirnazim9342]

i dont think these are the kind where the gas line has an extreme pressure. The injectors do all the work here which is why they are so expensive.

[@ebmotorsport2006]

Thank you I will be attempting this now. I know exactly what you are talking about with the brake cleaner sweet smell

[@andrewr1988]

Hi , thanks for the great video . So I have been having misfire issues for the past few weeks so I ordered brand new injectors for my n55 and I’m still getting the same misfire/rough idle along with a “SES” light (p0171) , my mechanic told me that they would need to be coded , could that be the possibility for continued misfire and performance

[@huguesgalvez728]

Super bon boulot, un grand merci !

[@tomsky8414]

Great VIDEO. Thanks

[@Galileo9.81]

Very nice. Just got mine done as well. Btw, what oil do you use? I use 0w-40. Some say 5w-40 is better for turbo engine. Yes, my car def smelled different at the first crank. I do also get quite occasional afr, trim, throttle spikes while cruising with very light pedal. Can you guide me what it might be? I thought it was the injectors but replaced all 6 injectors and plugs but not it spikes still. Thank again and your videos are Awesome!!!

[@matthewweisdorfer7757]

You could use a crows foot attached to a 3” extension & torque wrench to tighten down the fuel lines to the injector & fuel rail.

[@zeenmuch90]

yes but using a crows foot and the 3" extension changes the input torque value on the fastener. you would need a torque value specific for using a crows foot. Be mindful of that.

[@robertlopez3477]

Really appreciate your videos, thanks. Have a question. I have INPA and JB4 (no BEF) on a 335i. I connect well with inpa and can see live data values fluctuating car in idle, but when I give some gas to see the values on higher rpm's INPA stalls and I have to back. It reads at idle, stalls when I accelerate. Could it be the JB4 installed interfering ?? Take care..

[@nelsonweisberg2753]

So if i was fully stock and used reman injectors after a injectors service before installing would you recommend that can the injector seal be changed on the injector ? With the other seals u recommended ?

[@skoenig92]

Super video !!!! It really helps me out. And thanks for the intro. I now have epilepsy :DDD

[@alquehenwebb7349]

I learn a lot I have to change mine bless

[@cosminpopica]

Thank you brother but where do you take the new values from ???

[@JermaineLeeBlueprintAuto]

Awesome diy... bro... thank you....

[@Autonomous21]

Ive got a 09 535i drive and about to change the injectors myself with remanufactured. Car is completely stock with the dual turbo. But anyways I just ordered the Foxwell NT510 and have seen you can code injectors with it. My question is, is the coding with it the same as the coding you do here with the computer software. Seems a lot easier with the scan tool.

[@Zid2121]

Hello friend from Chile a query the sound you have is by air in the line of injectors? If so, how is it solved?

[@ItSpooling_]

you recommend using foxwell 510 for the injector coding?

[@pastormarkm]

Thanks so much for 64 bit, video! So I have to code my new set of injectors, but when I followed the links in the description to download and install the software for Win 10 64 bit the link does not work to download inpa (I believe that was the file anyways.) IS there another source to get the software?

[@saifulardi1969]

this is very useful. where i can get the new and old value for the injectors

[@modawadeh3496]

Hey man, thank you for the great video, my dealer want 3500$ to change mine, I have 2011 535xi, do you by chance know if I can download the app on my Mac? Thanks man

[@Shadowman072]

I upgraded my coils and plugs on my 07 335i , I have index 10 injectors , car is almost fbo, just missing the fmic. Running MHD stage 2. The new plugs I installed are one step colder. After installing I had multiple misfires. I swapped coils around swapped plugs around and did that for about 3 days. Finally I got frustrated and put the old plugs back in. Car runs fine now. Is there a setting in MHD or something I'm missing? I thought it was recommended to use one step colder plugs on a tuned N54?

[@juliocadena3559]

What bmw dealership in Houston was this at that gave you that price ?

[@tommyr95]

You're lucky to have a dealership in Houston that has prices like that. Here in Austin, I was quoted $250 each.

Hey i got the n43 engine. Its really the same job isnt it?

[@richcortez2251]

Great Video ! I thought it was my 02 sensors giving up because Im tuned with JB4 all bolt ons and inlets But that lazy cold start still happens 😞 So Now time for the injectors

[@chrissmith3378]

That could be a hpfp aswell.

[@peterforeste6524]

Just received my new index 12's from FCP today going to install but dont have the software, can I drive the car to a shop to code after install, will it hurt anything?

[@benp7548]

This is a great video! Very high quality and informative! I just bought an e93 335i 6mt with 80k miles and am loving it. It is currently fully stock. I did however notice that on a cold start the engine might skip a beat or two. Not always either. Not much more than that. No codes in inpa, no check engine light, no issues driving or misfires. Would you suspect this is an injector problem, a coil pack problem, a spark plug problem, or all 3? I could do the job, but I also cannot seem to find these injectors for any less than $230 or so. I'd rather put my money in the right place at the moment if I need to at all. What do you suggest?

[@oseasalvarez1748]

Benjamin Palfi hey man I have a E93 as well I had that issue too same way you described it and got no codes, I firstly went with changing the coils and spark plugs and resetting adaptations (spark plugs smelled like fuel) and it seemed to work for a couple months but it came back and I ended up figuring it was a small leaky injector so I went and changed out the injectors and got new plugs and coils (since I bought them from FCP they have a lifetime guarantee) and issue is gone completely, 6 months now and everything is running smoothly no more hiccups on cold start like I use to get and I am tuned and run a 30% E85 mix. It’s well worth doing all at once especially if you want to tune your car. If you can’t just do the injectors because more than likely you have leaky injectors. Good luck on what you decide to do!

[@bebiotostao]

Hello there , i just installed mines and i have a small miss , no codes , wonder how cam i pinpoint witch one its acting up ! thanks

[@d1skinet995]

So I did this once and I had fuel spray out at me, this was not from the fuel lines and looks like it was straight from the injector hole. I did to check if injectors were leaking and then put the injectors back in without changing seals. Would that have been the cause?

[@westcoastnaturalwolverine4068]

Awesome video.

[@BryanChance]

I searching all over the video where you mention torque specs for the fuel line and the bracket that holds down the injectors. 23nm and 10ft pound?? I don’t see it in the description. Thanks

[@matthewbowering7690]

This is off topic but when installed your rear inlet did you have trouble clamping it to the turbo. When i slide the inlet on the turbo its fits properly and doesnt move. When i tighten the clamp you can litterly watch the inlet slide right off the turbo but doesnt when i have the clamp off. Its pissing me off

[@cdoutland]

Will this process work on an n55 as well?

[@TaylorCampbellorMapleE30]

Awesome guide, helped me out on replacing one of mine that went bad, gonna have to get the rest of them replaced soon, but the biggest help was the Inpa walk through as well. One question I had was you mentioned that was your secondary laptop and mentioned you can put the software on your daily laptop if you are able to format it if needed or erase its contents, why would that situation present itself? Faulty software? bad download? or is it something from the software that can bug up your computer, also I have a Samsung Chrome book, will that run the program or do i need to have windows OS (win7 or win10)? thanks again for the great video, probably going to watch the rest of your video over the next few days lol

[@VehicularDIY]

Hey great to hear. Yeah so you could use your main laptop but if something goes wrong with the install you might need to format the computer to get around the issue so it's much easier to buy a cheap used laptop and run a fresh install.

[@draytonPW]

I mixed Index 12's with Index 1's and I had nothing but problems. It's hard to say if it was actually the mixing of the Indexes, but when I finally switched to all Index 12's I had no more problems.

What do I need to do if I put in a new engine because my last engine seized from a bad injector, I'm close to getting the new motor in. I haven't yet verified the injectors that come with new engine but I have a 2011 335is.

[@yousefsassya]

How long into the previous install did you have to replace the seals with the OEM Teflon ones? I am currently running a budget build of sorts and would like to know please. Thanks!

[@VehicularDIY]

I only replaced them with OEM Teflon seals due to the fact that I pulled them out a couple times. They were in there for over a year without issue before I pulled the injectors out.

[@chrisoberhoff8634]

Thanks for all the helpful N54 content. I just attempted this because my no.6 plug was completely black with dry feathery carbon. I went with a Foxwell nt510 scan tool for coding due to laziness . Unfortunately the car is idling poorly and throwing codes, it seemed to be running fine with the old index 8 injectors. Would you recommend using the IMPA software to re-codeor seek professional help?

[@VehicularDIY]

I'd say a good start is to pull up the generic OBD codes, they should steer you in the right direction. Do you already know the codes stored?

[@chrisoberhoff8634]

Yes, 2A19-tank venting valve activation; 29CF-combustion misfires #3; 29D2 combustion misfires #6; 29D0-combustion misfires #4 and 29CC- combustion misfires several cylinders...

[@erenozkan3157]

at 2:28 you have alot of pressure in those metal lines. when I loosened mine there was absolutely no air or fuel that came out, is this something worry about?

[@agusgolturbo]

I know its an old video, but you could also use inpa to start the fuel pump and prime it without having to turn on/off the ignition so many times. also its safer to check leaks!

[@dwent55]

Will a Bavarian Technics cable work for this?

[@ltdasilva93]

Hey i found out i have a leaking injector on #2 after changing my relatively new ngk spark plugs chasing a misfire. Noticed the spark plug smelled like gas and the rest were dry. Do you think a leaking injector can cause excess smoke coming from the tips? I've had that recently. Changing #2 tomorrow with a remanufactered index 12.
