This channel is amazing, thanks for all the amazing knowledge you have on these cars, could you do a video on the meth injection options/ setups? keep up the quality content
Thanks for this! Super helpful. I've been running a dinan sport piggyback on my 340iGT and had some super random stutters at low rpms, on tip in really. Pulled the tune and am running some injector cleaner through but code hasn't cleared. If there's no missfire or stuttering is it probably ok to drive to work more of the injector cleaner through to see if it clears the potential slight blockage and code?
I want to add to this, my car is completely stock and started to get a bad misfire, the only difference is that I put gas from a different Costco than I usually do and it happened almost immediately after, took it to the dealer, was there for 2 weeks plus got it back with new injectors, new plugs, new valve cover, car is running fine but I do notice a slightly hesitation on cold idle only, 2017 340i, 43k miles
Could a faulty injector also cause engine knock ? I noticed my acceleration times were getting slower. In 2nd gear you could actually feel the engine reducing power. Had it checked, datalog revealed that cylinder 1 and 4 had knock retarding. Checked the cylinders with boroscope, looked good, not too much carbon build up. Replaced sparkplugs and coils on those cylinders, only minimal improvement. The mechanic now suspects the injectors. Had no misfires and no errorcodes. M140, stage 2+, TU pump, 48.000 km. Thanks!
I would like to know that too for both you guys. I just got a cylinder 6 misfire. 140601 - Combustion misfire, cylinder 6: Fuel injection is switched off. 140610 - Combustion misfire, cylinder 6: detected. 144013 - Ignition, cylinder 6: Combustion period outside tolerance. 144018 - Ignition, cylinder 6: Combustion period too short.

Love your videos man. I’ve got a 2018 340i 6MT, about 54k miles. Tuned to stage 1 at about 50k, still on the original plugs. Getting misfires under high load, gears 1-3 are fine all the way through the rpm range, misfires at 3500+ gears 4-6. Not reading any fault codes and to be honest no clue how to read these bm3 logs. Planning to change the plugs this week, is there any way to tell which cyl. Is misfiring from the bm3 logs? Not sure what I am looking for. Plugs are cheap enough to replace but don’t want to change coil packs if it could be injector issue. Any help would be great. Lost on the forums online lot of contradicting suggestions as you can imagine. Thanks ! Keep up the awesome vids
Injectors are one of those weird things where it’s literally a lottery/crap shoot. People periodically replace them thinking it protects them from failures but the truth is it doesn’t and there is a chance that the new injectors you put in could be prone to failing or failing much earlier than the ones in the car. The truth is these failures are rare and very isolated as these injectors are basically used in so many different engines/cars. B38 b48 b58 bmws minis plus all the other oems that might use them etc What you hear is the vocal minority on the internet who drove around with a leaky injector which washed down the bore and destroyed the wire arc coating in the block. Believe me if it was that widespread you’d be hearing it all over the internet. TLDR I don’t think there are contributors to these failures and it’s more luck based. The advice you gave is correct. If you experience poor running of the engine stop driving it immediately and get it towed/diagnosed/repaired.
I heard that this injector problem was fixed by BMW in the post 2018 b58's with the later models using different injectors. If this is true, can us pre 2018 b58's replace our injectors with those as a preventative maintenance? What other options are there for injectors that could potentially eliminate this issue?
@@kern417 what's the best way to get a flow matched set of injectors? In my srt4 the best were ID or FIC. I'm new to the b58 platform and I'm finding it a little bit harder to find an oem set because from what I heard they can't be purchased as a set and come singularly sourced. Im heading toward 120k mileage and I'm watching a lot of your videos that the algorithm sends my way. Very helpful videos and I watched the one you did on aftermarket injectors that flow 20% more if I remember right. While I have your attention. What are the best options for me if I don't want to run a custom tune for aftermarket injectors? If aftermarket is the only way that ensures getting a flow matched set, which ones are the "go to" in 2024 for gen1 b58's?
From Australia. Have a 2015 340i @ 140,000kms Running TU Pump MHD OTS E40 for the last 30,000kms Bought stock @ 110,000kms. Daily driver on E40 for last 12 months and haven’t flushed with a tank of 93… Runs flawlessly although got me thinking should I replace the injectors ?
E30 not so bad but Ethanol in general is a huge problem for injectors if you let a E50 or more mix sit in your system for a week change or get your injectors cleaned. Bad injectors can potentially cause engine damage. You could also run a 10 micron filter like the ID750 to improve safety.
Kern I’ve been getting error 100313, I’m not sure if this means my DI injectors are dying. Car has rough start up on cold starts sometimes and I get this code. But doesn’t misfire under pulls or regular driving.
8:30 your saying bigger fuel pump isn’t putting more pressure. What iff you take the b58tu pump. Wasn’t that designed to run 350bar. So are you still don’t punt to much pressure on it ?
Biggest thing for me was the exhaust REEKED of gas, obviously the car misfired and was acting up. But thats a sure way to tell sometimes. Be sure to NOT drive the car. If it misfires and you smell gas and have a slow crank, TOW IT!
How bad for the engine can it be if you keep driving it when it won't rev high in this exact scenario you describe? BMW said no issue here and it's completely fine to drive if you have no EML or codes... Asking for a friend lol
Installed a HPFP the other day on b58. Ran stage 2+ 93 octane, was good for five hours. Car bogged down unload and just wanted to shut off, bad misfires. I changed all coil packs and sparks. I can only thing it has got to do with fueling.
I saw a Facebook post that someone had a super dirty Injector and someone said that it probably happened because they allowed the hpfp to get dirty when installing, did you figure it out ?
It was the dumbest thing ever. So I installed all my coil packs and apparently I missed one and forgot to bolt it town. So over time it slowly snugged it’s way out and became loose therefore lacking good contact with the spark plug and causing all sorts of codes. Can’t believe I wasted money on a tow truck to take it home only to find out the coil pack was loose.
There's not much you can do about fuel quality from a pump but if you're buying ethanol off the shelf or race gas then you know it's high quality. It's just a question really to see if it affects anything
If i let my car sit overnight & i try to start it in the morning it shuts right off, however the second time it runs fine does this seem like an injector issue? I know its definitely a fueling problem I thought it was my tune at first. If i put the car in diagnostic mode first & then try to start it it starts right up. This kind of makes me think that this may be the issue. Luckily I was randomly reading about cylinder washing & i found out about this. I hope I didn’t do too much damage so far if that is the case.
As far as i know, most of the times this issue comes from low quality gas, that's why i would only use 98 octane or higher on a performance engine like this.
So I want a 340i. I’ve heard good and bad. I sold my E46 and it was okay as far as reliability, I did maintenance on a regular. Do you think the b58 would hold up if I did simple stage 2+ FBO…? Would I have catastrophic isssues down the line, I’m talking like 100k Niels how would she be if I’m running stage 2+? I’m all about keeping maintenance up, oil change every 3-4K - liqui Moli oil ONLY!
wsup brotha. I personally believe you could pull off a CONSERVATIVE CUSTOM TUNE for stage 2+ or stage 3 (upgraded turbos) with the b58 in the long run. i have the same question as well whenever I first got my 440i. if you keep up with your maintenance it will definitely run for 100k+ miles if you keep your tune on the conservative side
@@ThatGuyNers1 main things I’d take care of before/at the 50k mile mark would be: differential fluid change, transfer case fluid, transmission fluid change, power steering change, brake fluid change, coolant changed

I also realized that while in comfort mode going slow like 5-10mph i get slight pops on decel with burble set to oem.. with that along with the car not starting immediately makes me think that this is strongly the case. I put a bottle of techron when i just fueled up to see if maybe Im contaminated
The TU fuel pump is designed to run at a higher rail pressure. I know rail pressure is regulated, though that's not how that system was designed to work (ie to compensate for a mismatched fuel pump) and considering we now have fuel system issues, it is a potential contributing factor. I also don't agree with you regarding pushing the fuel system to the limit of its capacity or running non standard fuel. Any time you exceed design requirements and safety margins, you have a potential for failure. So unless someone with engineering knowledge of high pressure common rail systems can give an assesment otherwise, that for sure puts extra stress on the injectors themselves or other parts that ultimately lead to the injectors failing.
The TU pump pressure is regulated fine due to how the control valve works. I made a video on it a few weeks ago. Check it out. I also explained why running different fuels within the systems limits doesn't cause it to fail. It's like saying your wastegate failed because you're running more boost. It has a range from 0-100% and it's an on-off switch. Opening for longer doesn't accelerate wear in that sense. You don't have to agree but those are facts.

Still no real answer to the root cause though, I reckon it’s temperature related as it’s nearly always No.6 that fails, I really want to stage 1 my car but I won’t until I know what the root cause is, as staying standard means full BMW Warranty
There is no root cause. It's not due to anything other than normal causes. Injectors can fail. I'll explain to all the different ways it can happen in the video.
@@kern417 yes but 90% of time it is No.6 that fails which is tucked deep away at the rear of the engine, the only obvious thing to me is it’s getting hotter, What do you think ?
@@kern417 the B58 forum I’m a member of has weekly failures, and it’s most commonly No.6 that fails, yes others do fail but 9 out of 10 times it’s No.6, you have done a great video explaining the different types of failures and how to test and troubleshoot, but still no ones seems to know why they fail open, which can cause catastrophic engine failures
I'm a member of several forums, groups, and constantly have people in my PMs. Injector failures are random across all cylinders. And many people have replaced injectors without issue. Typically the ones that have engine failure keep driving the car after it has failed.
Had misfire today cylinder 1and general message misfire several cylinders just cruising down the road. Got fuel injection shutdown. I believe it's just cylinder 1. Got the fuel smell. I shut the car off to inspect. Wasn't near home. Restarted and sputtered down the road really slow a couple minutes and got a really loud backfire . Shut it off and called a tow. After some reading, it seems running rich may have caused the backfire. Anyone else experience this? I'm hoping no damage occurred. Will be diagnosing and replacing parts soon.
@@Kingg4453 took it to the dealer they said it was the fuel injector but they couldn't get the car to duplicate the problem.

I also realized that while in comfort mode going slow like 5-10mph i get slight pops on decel with burble set to oem.. with that along with the car not starting immediately makes me think that this is strongly the case. I put a bottle of techron when i just fueled up to see if maybe Im contaminated
Thinking it may be stuck open? Mine does the same thing at 96k miles

biggs i have it were im in second gear coasting constantly pops but low tone ones im mhd and xhp

@@Adam-gv4zj check your tune
Is there any info on ways to check on 2018+ models if new injectors were used so you don't have to worry about this? Or is that just suspicion?
Not related
@@kern417 What do you mean not related?
there is no updated part number to improve reliability.
@@kern417 Got it. Guess best I can do is check at inspection time somehow, maybe defensively replace but that's like $1000+
I don't plan on replacing mine personally
Hi sir, do these injectors need coding after replacing. Or is it a adaptation procedure and DME does the rest?
I want to know
@@pedrojotajota1 adaptation procedure and dme does the rest. If your custom tuned make sure torque limiters are off. Hope that helps
S55 injectors fail too on e86
E85
N54, n55, volkwagen, audi...all Injectors can fail unfortunately
The TU fuel pump is designed to run at a higher rail pressure. I know rail pressure is regulated, though that's not how that system was designed to work (ie to compensate for a mismatched fuel pump) and considering we now have fuel system issues, it is a potential contributing factor.
I also don't agree with you regarding pushing the fuel system to the limit of its capacity or running non standard fuel. Any time you exceed design requirements and safety margins, you have a potential for failure. So unless someone with engineering knowledge of high pressure common rail systems can give an assesment otherwise, that for sure puts extra stress on the injectors themselves or other parts that ultimately lead to the injectors failing.
The TU pump pressure is regulated fine due to how the control valve works. I made a video on it a few weeks ago. Check it out.
I also explained why running different fuels within the systems limits doesn't cause it to fail. It's like saying your wastegate failed because you're running more boost. It has a range from 0-100% and it's an on-off switch. Opening for longer doesn't accelerate wear in that sense. You don't have to agree but those are facts.
@@kern417so when upgrading to a TU pump is there any chance to accelerate injector failure?
I said 2017+ builds have a different rail in the B58 group, not injector.
I got 2017 m140i yesterday has no issues so far

So is there anything we can do to stop injector failure ? And if an injector fails and you start getting misfire does that mean your engine is automatically done? Seeing stuff like this scares me so much
Usually people that have issues keep driving with the misfire. If you catch it, it shouldn't be an issue.
@@kern417 ok, I don’t think I have any misfires but my hpfp has kinda been crashing I think which caused some timing corrections, should I go Down to a 91 tune instead of 93? That’s what others reccomended
@@kern417 also would misfires cause a check engine light ?
Crashing is due to too much boost or fuel leak
@@kern417 I wouldn’t say it was exactly crashing but like 6000 rpm 3rd gear it went below target
Do you guys have a shop?
Nope
Do you need replace all injectors or is one good?
You can replace 1

@@kern417 thanks, im thinking of buying a 340i, what do you think of the b58 engine does the car have any faults etc?
it can have problems but generally it is reliable
Hi kern where is your garage located
It's attached to my house lol
What year is your 340i?
i have a 440 and it's a 2018
Hello
Have a 340i B58 jerks during driving. It does more while driving uptown. The actuators have been changed but the problem is still there. Have anybody any ideas? Thanks for help.
Scan for codes
There are no codes i was in my garage they dont find the problem.
run some logs where it's jerking to see if something is up
@kern417 There is nothing to find with logging.
Then I'm not sure. You should take it to a shop to have it diagnosed.
Still no real answer to the root cause though, I reckon it’s temperature related as it’s nearly always No.6 that fails, I really want to stage 1 my car but I won’t until I know what the root cause is, as staying standard means full BMW Warranty
There is no root cause. It's not due to anything other than normal causes. Injectors can fail. I'll explain to all the different ways it can happen in the video.
@@kern417 yes but 90% of time it is No.6 that fails which is tucked deep away at the rear of the engine, the only obvious thing to me is it’s getting hotter, What do you think ?
That's not true. It happens across random cylinders
@@kern417 the B58 forum I’m a member of has weekly failures, and it’s most commonly No.6 that fails, yes others do fail but 9 out of 10 times it’s No.6, you have done a great video explaining the different types of failures and how to test and troubleshoot, but still no ones seems to know why they fail open, which can cause catastrophic engine failures
I'm a member of several forums, groups, and constantly have people in my PMs. Injector failures are random across all cylinders. And many people have replaced injectors without issue. Typically the ones that have engine failure keep driving the car after it has failed.
With all these problems I thought the B58 was a reliable model...
No such thing as a reliable bmw
Had misfire today cylinder 1and general message misfire several cylinders just cruising down the road. Got fuel injection shutdown. I believe it's just cylinder 1. Got the fuel smell. I shut the car off to inspect. Wasn't near home. Restarted and sputtered down the road really slow a couple minutes and got a really loud backfire . Shut it off and called a tow. After some reading, it seems running rich may have caused the backfire. Anyone else experience this? I'm hoping no damage occurred. Will be diagnosing and replacing parts soon.
Did u solve it?
@@Kingg4453 took it to the dealer they said it was the fuel injector but they couldn't get the car to duplicate the problem. After they cleared the codes, the car started fine and the problem never came back. Been driving it aggressive on custom e60 tune and no problems. I do remember the car shifting real quick in lower gears full throttle sport mode in the redline. Probably had some wheels pin and fuel cutoff is all can thank of.
