its not a dual clutch. its a zf8 torque converter you don't seem to know much about this engine setup lol

the b58 engines are fucking amazing.

This dude's just regurgitating N54 and N55 platitudes from the forums with no actual B58 knowledge... what a joke, lol.

I’m trying to sum up what I just spent 10 minutes listening to and what I got out of it is the B58 is too new (fact check was out on 2016 models so well before 2019). Because it’s so new I’ve never put my hands on one but BMW has a history of this that and the other thing so you could be in for a rough ride but we just don’t know yet. Awesome... BMW has a history of problems going back for decades (timing belts popping on the M20, profile gaskets on M42, weak cooling parts on M52 and M54, emissions parts failures on the M57, leaky everything on the N62.). I’m limiting the list to cars with engines that I’ve owned and got my hands dirty on. Most of these issues started popping up fairly early on and were well documented on the forums or the Mike Miller’s of the world while you could still buy a new one. The B58 is now on its fifth year of production and from what I’m seeing online there is nothing that identifies a common trend for a major issue on this engine to date. Nothing. On the G30 forum the biggest recent complaint was that the 2021 configurator wasn’t live in July and the male Karen’s of the world couldn’t build a car they were eager to lease. Compare that to early years of the N54 and US M57. I was hoping this ten minute video would have a objective repair data, but it’s really click bait.

Coolant loss is common on all vehicle makes and models, I work as a honda tech for 9yrs now and 80% of the cars we do have low to empty coolant in reservoir that had to be top off. For 3 yrs now my B58(M240i) been damn reliable being on stage 2 410whp racing a hell lot every other weekend with zero issue. Don't let this video deterring you from buying a B58, perhaps best engine for modding, they can take a hell of a beating with not much issue.

B58 is a solid platform I haven’t had no issue with this engine my car is 2017 bmw still using this platform going into 2021 should say something about this engine.

I haven’t seen major issues with this engine yet. I’ve done a few valve covers. Also some water pump like the B46. I know it’s still kinda new but its good so far.

This guy doesnt know much about the b58.. sounds like a n54 fanboy

I'm on my 2nd one, Toyota trusts it and so do I.

I’ve heard of these problems and in a group I’m in with 5000+ b58 members i rarely see these problems. Me myself at 61k miles I haven’t had any problems

03:04 The b58 began production in 2015 not "2019 or newer"..

2018 440i 50K miles, water pump just went bad. It's covered under the BMW CPO warranty, glad it happened now. One more year to go on the warranty hopefully all the kinks get worked out now! ;) This is the only issue I've had with the car thus far, it might start costing money in the future but it's a blast to drive and nobody ever said BMWs were cheap to own.

B58 utilizes either the ZF automatic trans, or the Manual, not a dual clutch.

B58 is not a 2019 engine, it’s 2015 engine, it’s been out for nearly 5 years now. It’s a 2019 Toyota engine option, not BMW.

I had 2017 340i. Aside loss of coolant, no other issues you mentioned. Ran the car hard. Downpipe, tune with methanol injection. 28lbs of boost. Mann oil filter never showed any signs of deteriorating. Changed oil every 5k and sent oil to blackstone lab for analysis. Aside lead (due to race fuel) everything was in normal range. Before i got rid of the car it had 33k miles

2017 340i owner with 94k miles. I daily drive the shit out of my car and haven’t had to add coolant or a single quart of oil. I regularly drive to redline and launch the car off the line as well as high speeds on highways in Mexico ;) Only issue I have ever had is the active exhaust rattle and interior rattles

Nathan, sunscreen please! Been watching for over a year since buying my 2012, 128i, E88, N52. You get burned all the time, not cool. Stage 3 metastasize melanoma survivor. 10 hour surgery, bilateral groin dissection to remove my lymph nods. Beard is kind of cheesy. I'll give it a couple of weeks.

No issues from me and our group of b58 , 🤙🏼going strong so far

I have a 2019 BMW X3 M40i and have had zero issues so far. But the vehicle only has 13,000 miles, so I’ll have to keep an eye out for these potential issues.

For Europeans it also comes in all those cars, not just the 140i. It comes in all x40i models.

WARNING read the comments before you watch this...this guy doesn't know anything about the B58 or the 8 speed zf..alot of guessing and bullshit..BMW should be able to sue people like you.

Look this is overblown. The radiator cap o-rings is a problem overtime but so is improper flush-fill of coolant at the assembly plant and service centers causing air gaps in the line which overtime makes it look like its drinking coolant. Sometimes the coolant tank under pressure developes leaks as well. The VANOS valves are redesigned and largely run by two magnetic actuators near the rear of the engine and is reachable. Oil filter disintegration usually happens because the mechanic is in a rush and yanks the filter out since its on an awkward angle.. its user-error and the fact people run too high on oil change intervals (BMW fault on interval recommendations). The only thing that is a potential problem is the gaskets and the expensive valve cover. THAT I am afraid of but that is a problem for any BMW not just the B58. Surprise: the B58 is a commendable reliable engine from BMW. It really is a gem.

The b58 has been out since 2015.

One of my buddies who is a BMW mechanic is saying the common problem he sees on b58 is the Injectors are sticking open and washing away the oil in the cylinder wall and it's destroying the cylinder and the piston . Said he had seen it happen 3 times already, and 1 car was only at 50k miles

One emerging issue that is seen in the UK are rare cases of pistons losing pieces just below the ring lands. It is said to be caused by borewash due to injector failures. The pistons however don't usually looked to have picked up like you would expect from not having enough oil. Running the engine with damaged piston wrecks to coatings on the bores.

I was curious about potential reliability as Toyota was adiment about reliability since they too are putting their namesake out there and they demand reliability.

I have a 2018 540 with a stage 1 tune 32 k miles I have no issues

Yeah okay, I got this video in the first few seconds. Its been out since 2015 for five years now. And they in most BMWs in Europe too with 40i. Most of the 2015 cars are now between 60k and 75k miles now. I've heard about the coolant loss issues but they not very common even on cars that's got a stage 2. They highly tuneable motors. So whatever problems they have will be resolved by the massive aftermarket tuning companies even in Japan that's developing parts for it, because its in the new Supra.

Now the mechanical water pump is a plus because the older engines had issues with them just failing. Though the lubrication problems could cause issues with the rod bearings...

I got a B58 2016 340i tuned it to 385WHP and loving it no issues just regular maint. and good to go!

Can't even make a radiator cap that works.

How much labour to replace that valve cover? I hate to think.

b58 is solid dk what he's talking about, my dad has had his b58 for 4 years. Trouble-free ownership of the 440i he can attest to that.

This engine comes in literally everywhere, from BMW 40i models, to the toyota supra, to the incoming Ineos Grenadier and the Morgan plus six. Not to mention that all models with the B38 and B48 use the same architecture as the B58. There is a reason why it's so widespread...

Don’t know what this guy is talking about, these b58 been very solid and reliable and powerful! He probably made this video to gain views. Coolant tank cap goes bad??? Yes it does but I happens after 7-10 years especially when tip breaks off 10yr+, bmw recommends overhauling all cooling system every 5 years just in case, so neglecting cheap drivers create problems themselves….. B58 is great, everyone knows it, even Toyota! B46 has issues with plastic return cooling pipe and it can kill the engine quick, that’s true, they have a recall now, but b58 using rubber cooling pipe and no issues there.

Early model N55 had reported rod bearing issues. Post August 2013, all the rod bearings are shared between the S55 and N55, which i haven't heard them being an issue.

No leak no oil burns strong internals B58

It is a good engine been on go for 6 years

You know the b58 comes in the 140,240,340,440 and 740i for Europeans as well it’s not just America

Drat! Suffering from a moderate "car fever" for a 340i (2017 or 2018). This vid is curing my fever. Doggone it!

Most of yall in the comments have your ears plugged screaming "LA LA LA IM NOT LISTENING". He isn't saying that its a bad engine, just be warned because when that warranty expires and you have to pay out of pocket you will be well aware.

The only reason i came back to bmw after my last bmw being a e 46 My car is stage 2 and i am at 136k and no issues. One of the best engines bmw ever made.

There is a B58 Enthusiasts group on Facebook that highlights mods and failures points, which usually happen in that order.

As a 2020 540i owner I am seriously hoping the B58 turns out to be quite reliable in the long term. Good info and I guess I will keep a close watch on my coolant level.

For a company like BMW this is a shame...

The coolant loss issue is really annoying, I had been experienced twice over three years, each time required nearly 1 litre fill up. Not sure where it went to.

This engine came out in 2015? Just technical updates since then. There may be occasional issues but I think we know now they're reasonably reliable. PS had my VANOS solenoids replaced - so that's fair. They get gunked up I think. Cheap part but a couple of hours labour 😔 Needs more regular oil changes than specified by manufacturer

I'm all for creators, and the BMW community. This is the WORST most MISINFORMED video I've ever watched on this topic. If anyone is reading this, look elsewhere for a guide on the B58.

Wasn't this engine out in 2016?

In the market for an M240i, judging from the comments the guy doesn't know what he's on about. Skip!

Coolant loss is from cap and evaporating. Totally normal. Very minimal.

Worst case scenario if it goes bang!!!! You can pick up an engine for under 5k

Coolant leaks are just the cap, or somebody messed up and punctured the lines. Don’t think this guys knows much about B58 at all. I drive a B58 and I mod it and maintain it myself. None of the problems he mentioned are really an issue. The valve cover thing you can easily just replace the PCV diaphragm for about 100 bucks, easy fix. The oil filter thing is not common at all. The B58 engine was thoroughly tested by Toyota engineers, and if you watch Savagegeese’s channel, they interviewed Toyota, and they said this engine passed Toyota’s rigorous testing reliably. All of these “major problems” are plain bloated out of proportion, cuz it’s a BMW.

Yeah me too , I haven’t seen any of the issues this guys talking about , more common with the N54 N55 engines but haven’t seen it with the B58.. only with the coolent that I’ve heard some issues but Not so much the other stuff he’s talking about

Is a miracle if you find a E24 M6 in great condition for less than forty.

On my M240i the cam cover failed causing a coolant leak that caused an injector failure and misfire. This happend around 10k miles and was sorted under warranty (took about a month, they only replaced the injector but didn't sort the cam cover and it happend again). BMW refused to put a camera down into the engine to see if it caused any scoring.

Good info thanks

Another reason to keep my E90 330i with the N52B30. BTW: I love the BMW in the background

Bro these are not issues, regular maintenance. 🙄🙄🙄

I am getting a fault 'excess pressure in refrigerant circuit'. Causes RPM at idle to fluctuate up and down. Uses lots of coolant from the smaller tank. Could the cap be an issue?

B58 huggers coming out of the woodwork

I currently own an n54 powered 335i and am welcoming the b58 once it becomes into my price range

Nathan how does the N54 make large dyno numbers with out the rod bearing issues you see in all of the M car motors. Could you do a video on the highest horse power BMW engines and do a segment on your knowledge of the N54.

Holy crap I thought you bought something with this engine haha.. Great vid tho. *Wait...(with slightly squinted-eyes)... or DID you buy something with this engine!?. *insert Dr. Evil laugh* hahaha..

I tuned mine to 400hp and I'm screwed now

What??? These issues are still present today? I thought BMW learnt their lessons with coolant systems from back in the M54 days.

I have the same problem in my B58 "fucking plastic valve cover leak" luckily bmw replaced the rocker cover with a new one under warranty

I was unfortunate enough to have my oil filter disintegrate. Bmw accepted no responsibility and I'm left with pieces of the filter everywhere. £45.000 car

I think for most bmws it depends on how you drive the car and if you abuse it way too much you are fucked

I've heard of pcv issues but not about the cover leaking.

This is a very smart guy, I've watched several of his videos and he's always right on point.

An engine that's been in production since 2015, too early to tell 🤔

Just because you don’t get the 140i in the U.S. doesn’t mean it’s for “europeans only” ;)

Bro what kind of bmw should I bay buy

can guarantee you bro has not had a b58 nor will buy one; bro has no idea wtf he’s talking about disregard

in switzerland an germany we dont have these problems with the engine. :/

this guy knows nothing about b58s

What about those who tune it to get another 60+ HP. How does that affect the engine and components. Does it put more stress and wear?

Done tons of research, no common faults on the b58, solid engine all round, wtf is this guy on?

Hi Nathan, just wanna ask do you read and respond to more of your comments than Dean does? I asked him a few things about maintaining amperage during coding and even asked if I could pay him to do me some coding on my car. But he doesnt really seem to read his comments lol or atleast he hasnt yet after afew days. Can I ask you the questions I had? (i live in uk so thought it would be better to ask him first lol but got no response) Love the videos, I think I've been subbed for a while but I always come to either you or Dean for problems with my BM which is like every other damn day lol. I really wanted a b58 but ended up with a n54 vert because I got a amazing deal on one in the UK but its mega unreliable lol and I wanted some coding and crap done to it. Thanks!

ok i got 3 minutes in and realised you dont know what youre on about, ive had 2 of the M240I with the B58 engine in the last 4 years not once did i have a problem with anything you said! I then thought "maybe i havent owned the car long enough" so i went and did some research and again even with the higher milage engined B58 they didnt show any of your problems you mentioned apart from the small amount of coolant loss. You need say time and wear in you vid at about 5mins but how would you know? youve already said in a round about manor that you will have to wait and see..Please do your research and stop talking shit!

is mhd the best ots tune for the b58? if not one of the best?

Australia and Asia get the M140i as well.

Hi Nathan, do you work on other peoples cars?

What a load of bullshit! Stop relating to other vehicle makes....

My biggest concern with the B58 which was not mentioned in the video is that the timing chain and vanos are at the rear of the engine right against the firewall. BMW and Toyota must have some real faith in the timing chain with this engine. The vanos can still be serviced with special tools without dropping the engine.

Great video Nathan. Why is it so. hard for BMW to prove engine design before selling them to the public? sndh

Not going down well with the fans this info is it bro😂

Oh god... Your informations are so not on point, it hurts my ears. You got wrong even the basic info, lol

So you’re telling me i sold my n54 to buy a newer n54😂

Great video! Would u do this kind of review on the S55 engine?

Engine’s actually from model year 2016 not 2019 so its been out for a little while we haven’t really seen any B 58 engines with over 100,000 miles yet so it’s gonna be interesting to see how these cars hold up over time as much of a good rep for the most part the dissension has I have high expectations for other than the problems that you mentioned Nathan but good video

What about a e450?

4 major problems but its too early. Lmao Hey Nate, what are your opinions on the 530i before i buy one. They had me on my 550gt and im not about to be fooled again.

Drove an e90 325 i, sold and bout an b8 Audi a4. Bmw felt a lot better to drive. Looking at a 2016 340i with M performance package, just worried about mileage. It’s currently at 80k miles, is that too much on a b58?

mostly speculative, no meat

Nathan, that staircase.... when I close my eyes I see Frank Sinatra coming down from that stairs lol.

This guy has no first hand experience hes just going off stuff hes read somewhere. Currently have 200k on my M240i no isuues.

Sounds like a good old boy too me...

2019 and newer? 2017 bmw have the b58.
