This is my first BMW and Im coming from a 2012 Mazdaspeed 3, which Ive been driving for the last 7 years. Ive had issues with my 2018 440i not idling correctly. Over time, the housing and the electronics inside degrade and fail. It basically has a more aggressive tune from the factory. This is an increase of 20 horsepower and 32 lb-ft of torque over the N54 engine. Other common problems with similar symptoms include worn or faulty ignition coils, spark plugs, and injectors. I just bought a 2017 April F20 M140i x drive and I am These issues seem a recurrent theme, so made me wonder about the long-term costs of maintaining the engine. F11 151k miles (now only tuned by 30%, in the past was tuned onev 40%) The pistons are cast, but remain strong, and the B58 receives Electric Arc Wire Spraying on the cylinder walls. I hope to get a 2015 M3 in a few years time as i would love to drive the S55! That could be said for many modern engines. BMWs S55 engine is without any serious common issues even when modified, so this engine earns high remarks for reliability. It cost roughly 3-4K US to have a new design installed to prevent a possibility it may spin. I found remove driver side first. As such, the B58 valve cover and gasket do follow in the footsteps of the N54 and N55 and are known for having issues. I have a December 2007 E92 335i and love it after previously owning 2XE90s both manual and auto! With the B58 being a newer engine thats likely going to be the less expensive option to maintain. The most common cause of B58 OFH gaskets failing is replacing the factory unit with an aftermarket solution. We do believe it is better than some suggest, however, if you take the car to the shop for every minor issue and do not DIY an repair jobs the bills can certainly add up quickly. Haha your last comment seems to be spot on! Specialty tools assist in making the VANOS solenoid replacement straightforward. Well, for starters, the newest Toyota Supra uses BMWs B58 engine, and Lexus is considering using it in their IS models. Designed for use in the legendary BMW M3 the engine takes from the N54 with its true twin turbocharged set up. All rights reserved. The B58 uses two solenoids. As such, it can't hurt to replace the valve cover while you're in there. Reliability scores the highest marks compared to the N54, N55, and S55. I bought it at about 75k. Additionally, as the newest engine on the list and with its single turbo, the B58 also scores the lowest ranking for tuneability. Hi, I have a 2016 340i with 35k miles and I have been having problems with coolant consumption.

A few recalls and service bulletins do exist for the B58. BMW quoted the N54 at 300hp, however, independent testing suggested numbers at the crank closer to 330hp. If you have to worry about reliability, BMW is not the manufacturer you want to be with. A code scan revealed code P0012. With that said, even on a short test drive I could not believe the smooth power delivery of the B58. Stupid technicians, or cheap skates that mix coolant with distilled water cause cooling system boiling point to fall. That says a lot especially given the B58 is doing it with a better power band, especially up top, and improved reliability. Minor leaks may not produce enough smoke to notice. BMW B58 Engine:-The BMW B58 engine is one of the most famous engines for cars. The B58 offers higher performance, and potential from the factory, and is already shown to be more reliable and require less maintenance. BMW Reliability Most Reliable BMW Engines. How do the BMW N54, N55, B58, and S55 stack up against each other? Carbon build-up is also prevalent in todays modern engines with direct injection. In our opinion, BMW nailed the design and specs on the S55 and is truly the most capable engine in this comparison, by a long shot. Why? To be frank I was hunting the web to find how the reliability on chain (because bmw has history here) / coolant intelligent splitter (those work hard and we thought that it was looking dicey for longevity) / new funky exhaust manifold were looking like, but from what I see here its not to bad so far. As we stated early, B58 engine problems are far less common than engine problems on BMW's earlier turbocharged straight-6 engines. Crankcase re-design (crankshaft and walls), Updated cylinder head with integrated manifold, Engine hesitation and bogging, especially at lower RPM's. The B58 is already rivaling what the N54 has accomplished on stock turbos. Compared to the two former engines the N55 has been on the road longer, allowing for additional time for tuning developments. I add small amount of coolant from time to time, but nothing crazy. Don't sweat it if you're only topping up small amounts on occasion. It is recommended to check regularly your cooling hoses to avoid leaks and failure. You can indeed tune an M340i without voiding warranty. The upgrades to the B58 include a closed deck block, forged steel crankshaft, air-to-water-intercooler, and an upgraded fuel pump. 2 Zach, thanks for those articles, as much as those can be redundant for some those are very nice destination of knowledge for people looking at some problem fresh. Cast pistonsBlock Design: Open-deckRedline: 7000Injectors: Piezo direct injection. The B58 has proven to be the most reliable modern BMW engine, perhaps as reliable as the naturally-aspirated N52. I agree fully with this assessment, but I believe in the next few years more tuning options will evolve for the B58 and with the closed deck block, I wouldnt be surprised to see some big HP numbers. Where the gasses end up is dictated by a diaphragm in the PCV system. That being said, there are a lot of bad engines out there! Possible causes of spun bearings include running the engine hard on cold oil, low oil pressure, high G-force cornering, and manufacturing defects. Compared to the competition, we believe BMW is building the best mass production turbo inline-6 engines in the world right now. My car is going in to BMW on Thursday. )Displacement: 2979cc (2.979L)Turbocharger: Twin turboCompression: 10.2 to 1Bore x Stroke: 84.0mm (3.31) x 89.6mm (3.53)Internals: Forged crank and rods. Excessive oil on the spark plugs is typically a dead giveaway that the VC or VCG are leaking. Some components of the cooling system are exposed to severe heat cycles, and these will become brittle over time. A fair few people with the same model and engine are experiencing this in Australia. N55 water pumps are notorious for their low lifespan. when removing the reservoir cap, I noticed a bunch of crustiness. Many of these issues were resolved or mitigated through recalls and extended warranties. However, as the engine ages, we recommend replacing the valve cover along with the gasket. Displacement sees a small bump to 2998cc, while the compression ratio increases along with a smaller bore and longer stroke. Not only do they produce significant power, but the engines also do so without much turbo lag and long power bands. Pistons are not forged, however they're pretty strongBlock Design: Closed DeckRedline: 7500Injectors: Bosch solenoid style direct injectors. It cleaned up ignition timing a little bit, too. Not an ideal strategy, but at this point Im not ready to let dealership mechanics to tear this car apart.

Should I continue looking for a used BMW or Replace the accessory belt every 80,000 miles. Some owners are reporting coolant losses in the main tank and possibly in the second tank. My '86 CJ-7 had the Inline 6, 258 cu. Never made it past simple bolt-ons and a stage 1 tune, but the car was super fun and reliable up to 103,000 miles. (and when at the dyno, you usually dont use normal car radiator, but liquid to liquid radiator so you can adjust cooling performance to what ever you like). Your email address will not be published. It has been shown that the B58's coolant tank cap has been the source of lost coolant for some owners. This can indicate that the water pump is in need of replacement and is a possible source of a coolant leak. Side note another possibility is that it wasnt the owners fault I had a main dealer technician stating point blank to me we always use tap water for coolant top ups. Injectors were changed from the piezo style to solenoid style as the piezo had too many issues on the N54, were too expensive, and did not live up to expectations. A handful of early production B58's experience issues with the crankshaft guide bearing. Right by the timing chainat the back of the engine. e91 189k miles However, fault codes will help point you in the right direction. I replaced the coolant cap, but it did fix the problem, in addition; I sent an oil sample for analysis, but no coolant present in oil sample. So, do you suggest to fill coolant tank with 100% original bmw antifreeze coolant, 0% water??? After numerous visits to my local bmw dealer, it got a new engine. Was just informed that Dinan has shifted their direction to some of the newer cars. Now, we left out some potentially promising information. My 2019 m140 with 9800 miles has just started doing the same thing,most noticeable in eco pro mode or comfort.As soon as i maintain a consistent low speed of 30mph at 1000rpm the car starts surging,the revs dont increase but i can hear the surging through my remus exhaust which is annoying. And thats the N54 which is regarded as one of the less reliable BMW engines. Stay safe everyone! 350-400whp will require at least a decent set of performance tires. Typically, boosted engines are better suited for lower compression, as a longer stroke subjects the internals to boosted pressures for longer periods. We are hoping to soon add an F80 M3 and F82 M4 GTS. . Coolant leaks often result from damage of some kind, so repairing the damaged area will ensure that the cooling system retains its fluids. Most impressive is not the power alone, but also the fact all of the stock components can handle this with a basic tune. Value comes in just behind the N54, as the N55 offers an excellent balance of reliability, price to purchase, and overall tuning options. Excessive oil consumption is another big one that can alert you to this issue. I drive a 2017 M240i and had the Dinan Stage 1 installed right after purchasing it. I have a 440i with m performance and sound kit during cold start there is shaking in the car I can feel the shaking if I hold the stearing wheel with both of my hands I am not sure what might be causing the problem only have about 25k miles showed to dealer they dint find anything It felt a tad quicker than my current car, BUT steering feel was much more muted/less direct. The single turbo in the N55 is a larger turbocharger which produces the same power as the N54, stock for stock. Thanks Zach! My history with bmw is: No worries , the tone of my post was made Often small issues become Chinese whispers , and the vehicle and its components get a bad rap.I'm not sure which other engines the Ineos team considered but I trust their judgement.Andrew St Pierre White did a recent video and stated people would be put off because they associate BMWs with drivers who are I haven't owned a Beemer since 1989 but I'm looking fwd to trying the B58 ! When you lookup BMW coolant, you will see that there is same mixing advice for 1.6 non charged 80bhp mini cooper for Canada region and M3 for UAE region. The Grenadier will be no different. Ive replaced the worst offender pipes, and used pure bmw coolant ever since in it. Your comments are welcomed. Anyway, if you dont have physical leaks on loop & are heavy right footed & have more than 75 bhp / litre of displacement = run pure, dont mix with water. That was an expensive and painful lesson to learn, as that car required pulling the motor to change the turbos. Happy I stumbled on this website and will definitely be reading more. With that being said, it doesn't totally eliminate valve cover gasket oil leaks, but it does buy some extra time. If you get a downpipe and aftermarket tune youll definitely want to remove the cold start function. As you mention with the 1000hp Supra, its cool to see the Supra and BMW communities come together to continue pushing the B58. You should replace the B58 oil filter with every oil change, anyways. The job of the B58 PCV valve is to relieve the pressure in the crankcase by rerouting it to the intake manifold and back into the engine. e90 200k miles. Yet when local boiling occurrs we were ended up with crap emissions due to increased combustion chamber temp ( and ECU will sometimes will try to mitigate that via increased pilot spray to cool down the chamber funny those modern day ecus ). Yeah I agree with Tazzieman completely. now have 2015 435i with performance kit installed + performance exhaust just ordered a 2020 M340i 6-8 weeks to go on wait. Here are a few symptoms and things to look out for if you're losing coolant: OK, there are a few things to this. It's a pretty labor-intensive job. Your email address will not be published.

Nonetheless, you must pay to play and the N54 is no exception. The ML variant makes 335hp while the OL features a staggering 382hp. N55 is better than the N54, but its just a reliability upgrade. Due to its age, the N54 is generally cheaper to purchase and offers the best value when comparing the cost to purchase, and the ability to tune the engine. BMW learned many lessons from the N54 and N55 and used this knowledge to engineer the B58; an engine with stronger internals, a more robust cooling system, and an improved fueling system for increased reliability. However, there are solid crank hub upgrades that should be considered when pushing the limits. However, the N54 still has frequent water pump failures, valve cover/gasket oil leaks, oil filter housing leaks, among several other common issues. Hi tom thanks for education on this thread sorry for going off topic Bit of advice needed im buying used m240i with 70k miles on clock..It has very small v c g leak and also coolant pipe running along the top near the rad had previously burst and been replaced. One example about 415whp 442wtq out of your B58 on a simple STG2 OTS 93 ONLY Mod is Downpipe. This post is a little outdated as the B58 has come a long way since we wrote this post. The B58 timing chain was moved to the rear of the engine. This helps with the length of the connector cable. Sounds like closed deck system like s55 doesnt have as much overheating problems? Well, I have N54 running 550whp on td04s. Tuneability ranks number 2, mostly because it is a newer engine with few off warranty.

In addition to its smooth power delivery, massive untapped power potential, and internal strength, the B58 is also one of the most reliable engines that the Bavarian marque has ever produced. This isn't absolutely necessary but will help get any possible filter debris out of the oil. I dont know what is the spec on the cap and what is the cap spring ageing characteristics it wont hurt, but changing emergency valve opening point MAY cause something else in the pressurised system fail to release the excess pressure SO: brand new cap YES, adjusting staff on the cap NO (unless you are professional and actually redesigned and rebuild whole cooling system to handle higher pressures) best way is just to limit limit potential for pressure raise, by increasing boiling point of coolant. Fortunately, BMW learned its lesson on the N54 and focused on improving the reliability of its future turbo engines. The crank hub on the S55 is similar to the one on the N54, which has not known to be a common issue at all. The B58 is more reliable than the N55. BMWs B58 and S55 engines are newer, so more issues may pop up down the road. Crank and block should be plenty strong to handle 800+whp. Outside of that, meth definitely has some great performance benefits. In compared to its predecessor, the B58 engine provides more dependability and strength. Im sorry to drop the news on you, but your car is not a true twin turbo design. Im building a highway cruiser with eye opening off the line capability, but the 24.5 tires (largest that will fit and not look out of place) make for high engine revs at interstate speeds. Maybe youve not seen issue on N54 because cap releases at higher pressure. Thanks for your help! Therefore, I will not purchase a BMW unless it is a certified BMW. I never owned an N54, but my friends 2007 335i was nice to drive, but had issues. It is also known as a straight-six naturally aspirated engine. A tune and bolt-ons will take the B58 into the 400whp+ range; outstanding for a 3.0 L engine, but nothing insane compared to BMW's other inline-6 turbo engines. Its that sad with bmw. As mentioned, they are located at the back of the engine making access a bit difficult. Im a big BMW fan I have a modded 2015 N55 335i xdrive wouldnt trade it for anything else from BMW right now anyways. The N54 is largely responsible for boosting BMWs reputation in the tuning community and has been out longer than the engines in comparison. Deposits can cause misfires and power loss. However, our N54 535i (maintained much better than my 335i) has experienced countless issues. Something doesnt add up. Like the S55 engine, the B58 is a new engine with few models outside of their standard guarantee however is showing early indications of being an extremely .

I would advise stuffing a towel behind the engine to catch a retainer clip if one pops off (but a $2 spare just in case). Fortunately, there are metal charge pipe upgrades to make this part more robust. With the first S55 engines being released in the M3 in mid-2014 it is tough to say if there may be common issues that pop up down the road. Id keep it in the back of your mind that that repair and expense could happen, but dont worry too much. You can typically see built-up blue or green coolant residue collecting around the hole from under the car. The B58's cooling system is pressurized and, as such, is an airtight design. Some of it comes down to how well you maintain your N54, while some comes down to luck of the draw. Just purchased a 2021 M340. Of the engines referenced in this post Toyota is only using the B58. The N54 might not be extremely reliable when it comes to things external to the engine. Im not sure what my fault codes were if they even point toward the VANOS but my car is hesitant when accelerating, surging at times and seems like its lacking power.. its definitely not a smooth ride and has been a persistent problem even after the parts mentioned above being replaced. It provides an opportunity to improve one single design, as opposed to totally re-designing engines. Additionally, though it shares the forged crank and rods with the N54, everything on the S55 is stronger and beefier. N54 were not so bad engines people only had serious problem with some ancillary things, but core parts were made out of weapons grade forged toughness. Only truly good engines bmw made were M20B20 series(2.0, 2.5 , 2.7) and the big sixes M30B35 along with all its smaller or bigger versions. Relatively speaking, yes. The M340i is a beautiful car and the B58TU is a great engine. Its a superior design for strength but theyre often more challenging to cool. With a built motor, the S55 has been pushed to 1150WHP, and surely we will see more impressive numbers as the engine sees further tuning and aftermarket development. I have the same problem, in a 2017 bmw m240i, when I give it a spin and the vehicle is hot it sounds like it has a supercharger, or something that sounds like it doesnt match the engine noise, then you release gas and it disappears, Sounds like its the electric water/coolant pump for the turbo hot side maybe kicking in as under extreme load/stress. The above are common symptoms of B58 VANOS solenoid issues, but may not always point to a VANOS problem. The B58 is a marginally larger engine displacing 2,998cc compared to the N55's 2,979cc and weighs 18 lbs more, but while making notably more power. Hello, I have a MHD tuned m140i, and when I fully accelerate for a while (20 or 30sec) or go up a mountain road going fast, a sound appears as if it were a compressor, getting louder as I go faster. Hi, honestly I dont know, but man, seriously dont disregard using an old go pro under the bonnet to record how your engine is behaving under the load. Though, it may be excessive on lower mileage B58's. Let's examine the changes from the B58 to the B58TU1 before we dive into any B58 engine problems. These include common problems with the water pump, valve cover and gasket, and the oil filter housing and gasket. Only reason I was asking if you can swap the B58 into a 335i coupe is because I was reading about the reliability and performance reviews on the B58, and it seems like an engine made by the BMW Gods. We were surprised to find this is not uncommon on other BMW engines, too. We appreciate the input and you bring up some potentially valid points. Too much trouble. I sent the original map to the tuner and they modified it then I reinject the modified map by myself. B58 engine reliability BMW engineers were able to resolve the main issues with the engines that preceded the B58, including: Updating the fuel system Modernizing the cylinder head They fixed issues with the particulate filters A fresh design for the timing chain B58 coolant pumps have been known to fail prematurely and cause significant coolant leaks as a result. Soooo if you have some noise under load best record it from engine bay. And for those with lots of money to spend theres the Ford BARRA 4.0 straight six engine! Last replaced plugs and coils at 190K. e46 380k miles True BMW enthusiast street-wear hand printed under our 40Roll clothing brand. N55 is my preferred engine in the E92 lineup. Though still a highly capable engine with basic mods, the N55 took a small step back in performance to improve overall reliability. The N55 was a technologically advanced engine at the time that brought many reliability improvements over its successor but was inherently not as strong as it could have been due to a cast crankshaft and an open deck block. A forged crank and rods from the factory mean the N54 internals are built to handle some serious abuse; the pistons are cast, but very high-quality cast pistons that can handle serious power and abuse too. Inline 6s are well known in Australia. Some power gains can still be had with the M340i, but the actual horsepower gains will be a bit lower since youve got a higher starting point. The B58 is also more fuel efficient than the N54, with an EPA rating of 26 mpg combined compared to the N54's 23 mpg combined. It makes hellcat owners cry all day, every day. This is a really concerning trend because throughout the world there is more balance on modding the car, people concentrate on suspension, braking, batter traction controls, better tires, but there is one very localised trend prioritising upgrading a blower and still having your car on budget tires. Huh, B58 can make a lot of power and is the best for reliability. For that reason, the B58 scores the worst value rating. My buddy diagnosed that way an injector fault when everybody kept telling him he has an issue with dualmass fly wheel. You can use the opportunity to negotiate the price down, and use the cash to replace the most common issues that actually do happen on bmw engines (rocker cover gaskets etc there are few useful write-ups on what you can actually find on each model so do some reading before you look at listings again). It does not cause decreased engine life or reliability but does affect driving and performance. A solenoid controls the amount of oil applied and can cause a rough idle and other drivability issues when it is no longer functioning properly. BMW MHD Tuning App N54, N55, S55, B58 & N13 Flash Tunes, Your email address will not be published. However, there is one catch on the B58. For a better experience, please enable JavaScript in your browser before proceeding. Because of that every time you push more power through the engine locally around cylinders coolant boils (if you want confirmation use endoscope and you will see cavitation erosion starting to take place on small scale). Compared to the two former engines the N55 has been on the road longer, allowing for additional time for tuning developments. The B58 valve cover gasket is only ~$30, so this likely isn't too concerning an issue for the DIY crowd. Open-deck blocks and cast pistons are not great at handling extreme boost pressures for long periods of time. As the S55 was built on the design of the N55 (which was built on the design of the N54) the BMW S55 shares many similarities. These leaks commonly develop around 70,000 to 100,000 miles. Hi mate. Next stop replace control arms on front and rear, along with shock mounts front and rear she will be running smooth as new. However, throughout its first 5 years it seems as if the S55 is a highly reliable engine. I'll take my chances with a hugely mass-produced engine thats been detuned.
