The SECRET To Replacing Index 12 Injectors FOR CHEAP on BMW N54 (135i, 335i, 535i)

As most of you know, the price to replace injectors on an N54 BMW is expensive. Unfortunately, the injectors in my 335i started leaking and required replacement. Since I don't like throwing money away, I decided to fix the issue the most economic way possible.

[@emilmetzger5185]

You failed to mention the importance of how the hold down brackets are orientated when re-installing. They are pre-bent and act as a spring loaded device to soften the impact from the combustion process along with the decoupler rings. If installed upside down, they don't function in that manner and can cause wear in the head bore where the injector fits into, eventually enlarging it, usually into an oval, and cause compression leaks and misfires. If left unchecked and installed wrong, it can, and will, ruin the head.

[@moenaboulsi23]

with all this talk, you failed to say how as well. the bracket is bowed. install it like looking at a rainbow, not upside rainbow

[@Iwillnotbepushed]

Hey I just wanna day you’ve been a big help to me with learning more about a engine itself and how to take care of it, also me and my ( bro ) plan to buy bmws this summer and I want the same one you have🥺I wanted the 135i first but I can’t afford 400-500$ Insurance for that car a month🤷🏽slow but surely I’m learning a lot more about this care and this fascinating N54 engine💯kinda been in my notes building my own setup as I keep watching your videos, oldest to new👍🏽great help, good guy💯

[@jake_spence]

Hey man! Thanks for watching. I appreciate that and am glad it's inspiring you. Insurance should not be $400-500 per month on a 135i! But keep saving and keep learning, I did the same thing before I finally got into this platform.

[@mxracingunlimitedltd7784]

Look into a BMW 128i 6MT, if the 135i is too much for insurance. Should be cheaper than a twin turbo rwd coupe lol. Theyre fun and light cars. Plus with a few mods and the oem 330i 3-Stage Intake Manifold, and a tune you'll be t about 300HP crank HP. With a great sounding, quick revving, amd extremely responsive engine in a great chassis. The 128i & 135i share the same chassis and lotss of other parts. They will both handle amazing with the proper mods. For example, a 328i is 230hp, a 330i is 255hp stock, and a 335i is 300hp stock. But a 128i is also 300-400lbs lighter than a 335i. Plus youd be rocking the last, most advanced (Full-VANOS), Naturally Aspirated Inline-6 BMW made after the E46 M3's motor.

[@EddieKM]

Dude I've been delaying my injectors because I couldn't get that German Inpa software to work on my laptop or connect to my OBD. If this app you are using really works, this is a life saver

[@tomharrison6762]

Good video Having refurbished and tested dozens of sets of these Injectors,testing the spray patterns,piezo stack integrity and leak testing at 205 bar,the biggest problem with these Injectors is fuel separation that causes the Injector to get sticky and fall out of its original calibration.The fact that you mentioned the symptom got worse in the cold,,points towards the direction of the waxes,varnish and olefiifins that forms during the continuous stop start and heat soak that percolates the fuel and causes the issue in the 1st place.This occurs in any of the index #'s including 12's.

[@pappyvanwinkle6580]

Where can we send injectors to have the piezo stack recalibrated?

[@VehicleVirals]

Knowing that I need them, I've been putting off getting the index 12s because of the steep price. This video came at the right time 😅

[@jake_spence]

I put them off as well, but the cold starts kept getting worse. You'll be glad when you finally replace them!

[@Nathan-gj8ch]

SAme here last night I searched for new ones and saw the $1300 price tag I was thinking of starting a IRA to fund the maintenance of this car

[@mightfight]

Keep your eye out on ebay I got a set of 8 for $350 from an auto part salvage seller on ebay out of a 2010 V8 X5M. He was pricing them by quantity because he had some others from other cars index 07 and 09 that were 299.99 for 6. He was a big seller so idk if he/she/they know what the indexes even are...

[@N54.S6]

For anyone here wanting to do this, please do NOT use Pen caps!! You will cause so many issues down the line with the seals. Even if you have to buy the tools and return them, you're going to kill your engine. People on the E90 forums have complained that this has killed their engine as the seal was not properly on there. 116$ for the tools, 75$ used sounds a lot better than buying a whole new engine or repairing your newly melted head.

[@delta8447]

doesn’t matter how you do it. as long as you can confirm it is sealing that’s all that matters. these tools work the same way, they are both compressing the seal.

[@N54.S6]

@@delta8447 You're an owner, not a mechanic. Already had to do 4 n54 motors from 23 year old kids using pencaps due to them either breaking the seal or not sealing properly. This is backed by the e90 forums as well. I made various post with photos on the e90 forums due to this. If you wanna use pen caps instead of the "proper" tool then you should sell your car.

[@lutimletap648]

The spark plugs you replaced with should have been 3 prong Bosch. They were updated from one to three prongs. Great Video. Just replaced my son's e60 with brand new index 12, spark plugs and walnut blast. The car has gained noticeable power gain in all range. Big difference...

[@rjsazon6690]

I believe he's using gapped colder plugs maybe one step or two step colder. I use two step colder ngk on mine and they are 1 prung which is what's use on these cars when running higher power. The stock ones miss fire at high power.

[@jake_spence]

RJ is correct, I'm using gappable 1 prong plugs. The Bosch 3 prong plugs are OEM, not the best for modified BMWs. Once you start modding, you want the NGK 1 prong plugs to adjust the gap and heat level. But if you're stock, the Bosch 3 prong plugs are fine. Walnut blast is another great maintenance item, glad to hear your son's E60 is feeling much better!

[@thepopo2323]

[@bishopkrout6323]

With these current prices I’ll have to try this

[@bobcooper1583]

Hey Bro, when you change coils, injectors, and plugs, you really should clear all adaptations so that the DME can restart the fuel settings. Don’t forget to reset throttle pedal throw after you clear all adaptations. This will force a quicker learn than just driving around for 100 miles and letting it smooth out. Peace.

[@BTSyaya]

Bob Cooper what advantages does this bring at all? I’ve never seen anybody suggest this after each coil, plug or even injectors change. I’ve done them all on my n54 and never had problems without doing an adapt reset.

[@jake_spence]

I've also never reset adaptations for these maintenance items. However, I don't think it would hurt anything by doing so. If you're troubleshooting issues, it's a good idea to reset adaptations. Otherwise if you're just doing maintenance, I think it's not needed.

[@MrLaloman18]

You are the man! From the latest Injectors to get to HOW TO EASILY CODE THEM, unlike other youtube clowns that ALWAYS NEVER show how to code them but you show how easy it is and how soo much money will be saved by doing this ourselves and not letting the Stealersheeps take advantage of the ignorant! Thank you very much for your precious time and effort in showing all of this to the world!

[@tomharrison6762]

Using pre owned Injectors is not very smart

[@smookey58]

Great job bro👌I didn't even know that you can coding injectors with protool. Time for buying protool 😁

[@jake_spence]

It's been a life-safer for me! Worth it, and you can use it on any BMW, not VIN-locked.

[@OakInch]

I got tired of waiting for a recall for my injectors in a 2007 e90 335i. Installed some new index 12's today using this video. There was a set of "index 1" injectors in the car--Which seemed pretty old. I have owned the car since 2009 and never swapped them. They never had any noticeable issues. I just figured it was time.

[@Justin-qs9nj]

Index 1’s are actually known to be one of the best, after 11’s and 12’s

[@yasser5380]

Hi mate thank u so much for da amazing video am excited can't wait 2 do mine.. Just one question what happens if I didn't code them?

[@The11HD]

Great advice! Went stage 2 and it seems like 5 out of the 6 injectors started to leak. I'm probably going to go 1 bank used 1 bank new. Are the used ones still doing alright?

[@friguy4444]

Pro Tool is AMAZING! I bought it and have never used INPA since. Jake's channel is the best N54 or should I say was when he was making content. Unfortunately he's obviously too busy doing other things in his life these days to make much content. I can't blame him if it makes him happy but it's a big loss for the rest of us. Sad face here. I am now watching "Zero to 60" to scratch that N54 itch LOL. But love Jake still! I was hoping the he was going to tell us some way of buying injectors of much cheaper than they are. But he's showing how to DIY to save the cash of getting someone else to do it. Which is great advice and he does a super job as usual. But I was hoping..... LOL.

[@micdev42]

Good glear video. Would it be a good idea to lightly grease the mating surface of the injector with ceramic grease before installing? This would make them easier to remove in future. Copper grease is no good as it can cause a reaction with the alumium head.

Yes, you can do that. However, if your index 12s are working fine, I wouldn't remove them to replace the seals and such.

[@commiesandmums]

Jake Spence not sure if they are or not. All I know is that my idle is rough with lots of hiccups and I’ve had a misfire in cylinder 6. I was told my code p112f was related to injectors and I need to replace them. How can I determine if the injectors are okay once I remove them? How can I tell they are bad?

[@alexfeole6212]

I got the same code on mine and it runs really bad under 2k rpm so I guess I’ll be doing this soon

[@commiesandmums]

Alex Feole just took it to my local BMW shop. Great people, very knowledgeable about 335’s. They said my p112f code was old and only happened once. Likely due to a boost leak. They smoke tested it and found no significant leak and confirmed I probably don’t have injector issues and was mostly likely due to bad e85 and carbon build up. Cylinder 6 is notorious for carbon build up. They recommend a walnut blasting if you are having consistent cylinder 6 misfires. Make sure to swap coils and sparks to make sure it isn’t an ignition issue.

[@Carlos-ro4ji]

Jake are you able to remove injectors to clean them, and put them back in without having to replace plastic ring?

Im not sure if its my injector that's failing or my hpfp, Im getting codes 29CD - Combustion misfires, cylinder 1, 2AAF Fuel pump, plausibility and 2E18 - Firing Cylinder 1. its on limp mode now. Can i switch the injector 1 and 2 to see if im getting cylinder 2 misfire to determine if in fact it is the injector thats the issue? and can i do that without replacing the rings and decompressor rings simply to diagnose? or can i casue damage this way? My original issue was after hard acceleration especially on the highway the car was choking / shaking. I have replaced the coils and spark plugs , which seemed to fix the issue for a month. few days ago i accelerated hard again and it went into limp mode and i am getting the codes above. Beforfe the limp mode I also got a code 29D9 Misfire at low tank fill level. prior and in addition the the codes above. Any suggestions? if it was the HPFP failing wouldnt I have issues with more than 1 cylinder?

Did you do the coding with jb4/Mhd disabled so that the ECU is back to stock or were you coding with JB4/mhd enabled?

Hello I purchased new (or so says the listing) index 12 injectors. They didn’t come capped. What should I do? Do I need to replace the seal on the nozzle? Or are they good? Please help I need some advice. Thanks!

[@joseevelasco4596]

Hi Brody I’m trying to source the cable connector and android you used wondering if you can help links aren’t working

[@tuurbow]

Just a comment: I believe it was running rough after the first start because you hadnt coded the injectors yet. Coding the injectors tells the ECU what the flow rate of each injector is.

[@samerhamed9484]

Hi Jake...I appreciate everything you do. I love watching your channel. I had a question about the index 12 fuel injectors. I have heard to stay away from ebay fuel injectors from other KZbin channels and to only buy new ones due to many reasons such as the inside is not going to be as good and they may fail and cause problems. I know you installed yours a while back and they are from ebay. Can you tell me about your experience 2 years later? Do you still recommend them? I purchased them from ebay which was alot more affordable but I have not installed them yet because the seller is sending me a new one since one of the 6 had the metal piece in the middle broken where apparently its welded. I am curious to get an update from you. Thanks again for everything!

[@8sbald8]

How are those used injectors holding up

[@mattolsen2589]

Just curious was your cylinder 1 closest to front on car your injector 1 when coding?

[@owaiskhan8609]

How is the car running with the injectors now? Need to replace mine because im getting some hesitation on my car.

[@AlbertaTacticalDude]

Thank you so much for this informative video! Lately my N54 experienced a misfire in cylinder 1 as well as really a rough cold start with frequent hiccups. A local shop couldn't find the issue but I suspect that it's a leaky injector. Could a leaky injector be the cause? I am not getting any fault codes pertaining to the HPFP. New NGK spark plugs and a precision raceworks ignition kit unfortunately did not resolve the issue either.

[@hackn3y199]

I have a somewhat similar issue on 3, changed plugs and coil without any change, I replaced the injector seal and decoupler yesterday and it seemed to have fixed it, but today it's misfiring again at start and low rpms. Waiting on a new injector, but hoping that's the issue. I did drive it earlier with some added techron fuel cleaner for about an hour, but still not right at idle. I think mine are index 1 injectors, so prolly need replaced anyway.

[@jake_spence]

Yes, to me it sounds like it could be an injector issue. Hard to pin-point it exactly. But you could let the car sit overnight and then remove the spark plug in the morning and see if it smells of fuel or has fuel on it. If so, I'd bet on an injector.

[@commiesandmums]

Mike Davies I’ve had rough cold starts with lots of hiccups lately too. Had a pretty bad misfire in cylinder 6. Got code p112f I believe?? Shop said it’s related to injectors. Exhaust smells of fuel

[@hackn3y199]

Just swapped my injector and so far so good. I checked the rough idle in INPA and it was going into the red beforehand, now everything is in sync. Purring like a loud direct injection engine.

[@xXicUtIoN4UXx]

Hey mate mine had the same issue its defiently a leaky injector my mechanic swaped injector 6 with injector one and the missfire went from cylinder 6 to 1 so defiently injector

[@kanagagota5228]

Do you have to tune the car if you upgrade the index of your injectors?

[@LexicalNoScope]

A word of advice to anyone, make sure you don’t strip out the bolt that holds that bracket down. The tech that did my injectors must have stripped it and when I overboosted over 30 psi it blew those 2 injectors out. Luckily I was able to tap a larger size thread on the head and tighten the bracket back down with a larger bolt.

[@jake_spence]

Good reminder. With the proper tools and torque specs, you shouldn't have any issues stripping bolts or threads. But I'm glad you got it fixed, shame that a proper tech would have that issue.

[@scottb4104]

Happened to me a bit ago, got cross-threaded then bolt broke off in the head.. Time sert is the way to go

[@setterlee]

Great video...!!! It would be nice if you mention the license cost of protool... 👍👍👍

[@jake_spence]

Good point! I can't even remember, I purchased it many months ago.

[@mrpocklington7540]

@@jake_spence around $200 ish, I bought it based on this video

[@Odysseus38]

Yo has anyone every said they love you because I think I do right now after watching this lol

[@alexanderedvardsen8320]

Can I use a K-can obd II cable with the ap? The one in your link is not available. Great video i need to replace my injectors on my n43

[@jake_spence]

Yes, I believe you can.

[@jonfield7777]

I was wondering if you had an updated link to obd2 cord?

[@seanthao]

There is now a recall on injectors for 2007-2008 n54 models. Not sure the exact months but it's a real recall!

[@jake_spence]

True, definitely worth looking into!

[@jt86tn]

If you don't have one of the 2007-2008 models there is also an extended warranty from BMW for 10 years/120k miles on the fuel injectors. It's listed under "SIB 01 17 15"

[@JP-st8sf]

Ive had to do this before and it works BUT i would spend the $80-90 for the actual installation tools

[@jake_spence]

True, but if someone is in a pinch like I was and didn't have any tools local, this will work.

[@huanweili7699]

Best strategy ever. Screw the actual tool. Lmao. 😆🤣😂

[@HydroxLoL]

Hey, I was wondering if I could use the protool app to code specific lines? I need to change radiostufe_2 to radiostufe_3_4 so my car recognizes the new LCI head unit but the computer software is genuinely a pain. Do you know if I'm able to do that? Great video btw.

[@jake_spence]

I'm not sure about that one. There is a BimmerGeeks ProTool Facebook group. Try joining it and asking the question there, they will get you an answer.

[@HydroxLoL]

@@jake_spence I'll check them out. Thanks!

[@kiyuutosa2118]

_the link of the programming cable doesnt really work. can you tell me the name of that programming cable that you plug to the obdii port?_

[@luideluna8977]

I tried this the pen cap doesn’t work unfortunately the gasket stretched so it does not fit inside the pen cap

[@jkiu2692]

What tablet where you using when doing the coding ?
