yeah that's why I don't like working on other people's cars because then you’re forced to deal with this kinda bullshit! They always get the last word and then it's like you're not even doing them a favor because they refuse to address the underlying issues which in this case is ultimately that they need all new fuel injectors. If it were my car, then I wouldn't even have to deal wtih this kinda nonsense in the first place and I could do everything my way. At least that's the way I feel.

My wife always asked why I didn't open a shop since I like working on cars. Well first I don't always enjoy it. Second, I don't like people. They're the problem.

@@pkt1213 exactly!

That’s amazing to me. When i take my BMWs to Johnny, I’m always suggesting replacing more of everything (than he wants to do) because to me it’s ALL about the labor and hassle factor of RE opening up these things, any car for that matter, Japanese American Korean etc.

Actually this time the customer might be right. The fact that those working injectors are of different revision than the failed ones means, that they were already replaced in the past. And even though they do suffer from the same problem they might still have several more years before failing as well, so it might be a right call to keep them there especially if the customer don't plan to keep the car for long. These injectors are not some cheap part costing twenty bucks that you replace just for precaution and don't care, injectors are expensive to replace and keeping them for little longer might actually make sense.

And it will cost you more in labor cost :P

If only people learned basic maintenance. I could do a single injector in about 5 minutes. It's extremely simple. A 5 year old could do it. Buy an Autel Maxi and you can code it too.

@@Tracked350Z I asked my 11 year son to do the injectors, coils and spark plugs on the family Toyota corolla while I was running new fuel and brake lines under the car. I not mad at all about having to do it. 473,890 miles. The car has just been a beast and haven't had any major failure. Just age related problems and maintenance stuff. My oldest who is 15 now will be getting it when he starts to learn how to drive.

​@@Tracked350Z 100% agree. That's how I started learning mechanic work, with BMWs. There's plenty of ressources online and videos.

At higher cost. People forget that you not only have to pay parts price twice but labor also. So for this job, that customer paid roughly $1,160 for parts and labor. ( Injectors $300 each X3 and about $160 in labor roughly an hour and a half.) Then a month or two later the other three start acting up requiring replacement so this dude gets to pay another $1,160. So if I did my math right that's about $2,320 versus $1,960 parts and labor to just replace them all at one go. But what's an extra $360 in today's economy right?

You are correct. And what’s amazing is how seamlessly he moves and without hesitancy. I’ve gone there several times snd never leave disappointed.

Wrong , he mixed index 12 injectors with old injectors , that’s a big no no !! Each bank should have the same index , so cylinders 1-3 should all be same , and cylinders 4-6 should be same , if customer didn’t want to replace all 6 then he should have removed older (good) injectors and put them into same bank and kept all new index 12 injectors in same bank , the car will have issues as it sees the injectors as a bank of 3 and adjusts to suit , but there will be an I balance in both banks now as injectors are mixed , ask me how I know !!

Snap, when i used to work on SAAB 8v's with K Jet. Sometimes they would fall out, others would put up a 30min fight.

@@dj_paultuk7052 Volvo's were the same although more fight than fall out.

That’s why he takes the specific numbers down to avoid said mixture issue… the computer compensates dependent upon the index and numbers from each injector

@@debraclancy2652 That's a different process that has to be done with any bmw injector replacement. An index below 10 is a different injector from the newest 12 being used. Shouldn't mix and match. At min one bank needs to be replaced. Since injectors on both banks are required, should have all 6. The customer made the call on this for economic reasons. Jonny was right to recommend all 6 and was overruled.

Nailed it.

I grew up in Europe in the 80's. People didn't accept lower quality and expected to keep cars for a long time. When Mercedes had a little hiccup in quality (W201 I believe since it slightly less reliable than the W123 and W124), the taxi drivers went to the head office to protest and raise shit. But the quality only went down much later and BMW managed to still be less reliable. The cars went from the Engineers and builders setting the bar, to the accountants. As of the 2000's, even late 90's, you have to do your research. But the Germans have always been better at building driver's cars.

@@pfsantos007 very true they don't accept junk. The food was better too. They have pride in who they are and what they do. I truly enjoyed my time there.

not to mention water cooled alternator, if i’m correct?

@@E46M54, you are correct. As big of a POS this thing was I still want a 135i N54. Once sorted, updraded turbos, FBO+JB4 guys are running like 21-23psi making over 600whp on stock internals SAFELY

Ah, the endless money pit that is the BMW... 🤑

@@crazyman8472, most, but not all. N55 was a lot better and now the 3rd edition of the turbo I6 in the B58 is like epic.

@@crazyman8472 couldn’t agree more. But...I would rather spend money on an old BMW, than buy something that doesn’t need any money spent on it of the same age and mileage, because that reliability suggests a dull car that was owned by someone who doesn’t care for driving.....

These injectors are in the combustion chamber and run very high pressures and over complicated for intended purpose vs port injectors ,on your E46, they should have been replaced as a set.

@@copperlocks1 Another reason to stay away from direct injection.

That's the cost difference between direct versus port injectors.

@@AJGreen-cn8kk I jumped in Head first and sank into the endless maintenance money pit🤣😂😂 , have not changed my injectors yet, but I have changed both low and high pressure fuel pumps and fuel pressure sensors.

@@TwentytenS4B8 I tried to reply not sure if it posted. port injectors depending on flow rate and impedance style ~$70-100 a piece on the N54 engines $300+ each on the later N55 engines the were redesigned and now cost ~100 - 120 each 🤷‍♂️

The coding of the injectors is because they all vary slightly in flow rate, so the ECU needs to know the flow rate of each injector to deliver fuel precisely. However the variation is small in the scheme of things, so it wouldn't hurt to start and make sure everything is running OK before coding them.

Still, why can't the German automakers make cars that are more reliable? My JDM cars arn't as fast, but they've never had major parts fail.

@@mattmalenda6585 well the answer is, it depends. “ reliability “ is debatable - the e90 328xi is extremely reliable and can easily go 200,000km without any major work but it’s not a sports car. A Honda Civic is a simple 4 banger without any turbos and they are extremely reliable but super boring. Typically for a car, you get cost, speed and reliability. Pick 2. Based on my experience, the more complex they get, the less reliable they are, especially cars with two turbos. Germans were always pushing the boundaries with speed… as long as it’s reliable over 100,000km, they have succeeded. But I will say, some of the cars they’ve made and some choices, like in the Audi’s were the timing chain is located on the back of the engine, is just dumb. I also think BMW had some questionable choice of Plastics suppliers were many hoses and gaskets are failing sooner then they should have (I.E. cooling hoses, valve covers, etc.)

@@mattmalenda6585 Could be because this engine is using high pressure direct injectors. port injectors last a lot longer because they are under a lot less stress. I have a 2008 Lexus GS460 with 80,000km it has 2 sets of injectors, one set for port, one set for direct - I expect the direct injectors will give up long before the port injectors ever do.

Probably was to prime the engine for starting in case the fuel pressure had gotten low. That way it starts up quicker because it’s already primed before you even turn the key and you dont have a “long” crank time. Yea in this one case it is an inconvenience, but also i al sure you are supposed to at least pull the battery cable to stop that from happening when are servicing fuel injectors or lines. But Johnny is the only one touching the car so he doesn’t need to if he doesn’t mind a little gas squirting out from the couple ones he changed.

I always disconnect the battery...

All you have to do is reset the clock after. Why risk the fuel pump priming?

Replaced a battery in a Renault using a voltage backup via the OBD port. Still had to enter the security code on the sound system and the windows got “lost “. Didn’t know if they were up or down and would stop halfway. Fuel pump in the sump of the tank have not needed bleeding. Have replaced a couple (latest in a BMW 1300 bike) without issues. I might be lucky but I wouldn’t bet on it.👍

Thank you. Yes we use such lights from Snap-On. We've used them in several videos.

@@realcarninja sorry buddy I have not seen the earlier videos yet so I guess I've got to do some catching up now 👍

I agree with #9 being fine but the oem are definetely to weak

I know, but this customer is a cheap gigantic pain in my ass.

Johnny Karaj legit😂👍🏻

Johnny, i always wondered will it throw a fault?? I’ve never tried to to mix the indexes. It’s an expensive job to replace all of them so i understand why he doesn’t want to do all of them, but luckily my clients generally take our suggestions on how to do this job. The ones that don’t, seem to get fired quick lol

@@powayimports4175 it doesn't throw a fault. What I found, is that, if you use an injector with numbers close to the injector you are removing, but a higher index; there's no issues. Between logging fuel data, af/r, and timing corrections. No issues.

I wanted to add though while this is true and there is a TSB on this by BMW, some members on forums have reported *zero* issues after over 8 months+ . These also molded cars. In fact I'm also going to do it myself as only my 1 injector is leaking all the others are fine. And sure it's not worth the hassle at a shop since you pay for labor but from DIY perspective it 100% yes. A very easy job to do unless some are really frozen in there but the puller tool llike Johny has works well. And tobehonenst the only reason why it's considered is because these are 300$ a piece. I hate replacing a part that ain't broke and that's expensive. I get preventative maintenance and I do like cooling hoses/waterpump, things that'll leave you stranded but for 2000$ ehhh maybe I'll give it some luck. Some members have some old indexes still running so.

I rarely ever see a clean engine on any car repair YT channel. I would say this one was slightly above average clean.

They're based in Wichita, Kansas so yes.

It works just fine. His tool is actually better because he can use it on a lot more than just the injectors. The injector tool threads on to the end of the injector and lifts the injector out of the port. His tool, a handy-dandy vice grip with the slide hammer literally does the exact same thing. It doesn't take much force to remove the injectors.

No tech at a bmw dealership uses those special tools to remove them. Only the new guys. I used a small slide hammer also

I have an Audi S4. And before I do anything with the fuel system I pull the fuel pump fuse and let the car run until the fuel lines are empty and the car shuts off. Obviously, leaving the fuse out and not opening the door until the job is done.

I’m guessing you haven’t tried to access the fuses on a 1 series before ?

Or even more simple: just disconnect the battery so fuel pump doesn't start at all.

Usually the bad injectors leak, and after sitting for awhile the spark plugs get wet with fuel, that’s what usually causes rough cold starts too

The ECU will tell you.

@@TwentytenS4B8 yeah usually through inpa, was it through the rough running program ?

@@gdw29 Jonny has a Maxi sys. Scanning the faults and probably running the injector test routine pinpointed the problem areas.

@@TwentytenS4B8 oh that’s cool

Autel Maxi Sys is what most use these days. And Abrites for coding\programming new modules.

The videos are shot with a Canon R6 and various Canon L lenses.

you cannot mix them on same bank, you can use lets say index 12 on 123 and index 01 in 456 but from experience, I seen ton of N54 cars with injectors mixed all around and it seems to work just fine as long as they are properly coded, probably not optimal tho to mix em

That what she said...

Well I could have edited my post. That's what happens when you open your mouth too early. Hahaha. That's why you're the Ninja. Thanks Johnny. Respect

@Oskar DirlewangerLol yes indeed...but some self respect to your vehicle would go a long way here.

Or, you know, they're selling the car. Come on kiddo, use that brain.

Impossible to tell when next will fail.

@BM VA he made that tool and I guess if they are shot they are shot but it has a slide hammer so it will work and that slide hammer prevents damage to the injector bore so thays what is really important

My dad got oil poisoning from never using gloves, and if he gets any oil on his hands, his skin breaks out with huge sores. He is 68, and uses gloves, because his hands cracking open looks like it would be painful.

I use them on and off. My main probably is within a minute I have sweat pouring out of them and down my arms.

Why would anyone want to do that? Lmao

Yeah that's an insane amount of re engineering. Direct injectors go into the cylinder whereas port injectors are generally located in the intake and fire at the back of the intake valve versus straight into the cylinder. You'd have a hole in the block where the injectors were in a GDI engine. If you're going that route just swap the engine for a port injected one. But don't forget to change out the ECU and associated modules and wiring. Hope you're good with coding as well.
