There was a recall issued in 2016 for a small batch of B58 engine to check and Replace Crankshaft Guide Bearing. The N55 has proven to be a reliable engine but is edged out by the B58. The ML variant makes 335hp while the OL features a staggering 382hp. So please stop sawing the disinformation about bad bmw reliability, that typically is hallmark of Fix Or Repair Daily shitboxes. Whats your thoughts on this? Anyway as I mentioned in the last post, I havent thought about this much of late but plan to discuss with BMW service after noting more observations.

Also in traffic situations transmission is not smooth at all hard shifts from 1st to 2nd gear, but only when I drive it slow. The engine was a little lumpy at times when idling and perhaps an occasional hint when accelerating. Nonetheless, you must pay to play and the N54 is no exception. Bit of methanol injection will help keep your intake valves cleaner. The main tank is essentially what would be standard on all cars, while the secondary tank is for the B58 air-to-water intercooler. Acnam Infotech, BMW Tuning - BMW Performance & Tuning Guides, News, Videos. Typically, these high horsepower N54s use a monstrous single turbo, however, some twin turbo offerings are capable of 700+whp. Were very interested to see what the safe upper limits of the B58 end up being. Thanks for the clarification and reply. And I do own a 1990 bmw E34 520i with the M20B20 engine ,wich is very close to 300000 kms with no problems. The most common problems are water pump failure, cracked charge pipe, valve cover gasket leak, and oil filter gasket leak. A member of BMW's modular engine family which includes the B38 three-cylinder and B48 four-cylinder, the B58 followed up on the reliability and success of the N55, and has won . )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. Great point regarding walnut blasting. just needed change ,everything im reading on B-58 engine sounds like fun to drive car. Thank you. Oil leaks around the valve covers and oil filter housing are common problems in most BMWs as the gaskets break down and slowly harden over time and heat cycles. Not quite sure wether its a B58 or still the N55 thougj.. any ideas? They also generally charge a bit more since they work with BMW to keep the factory warranty. The BMW B58 is a turbocharged straight-six engine, which began production in 2015. In 2010, the 335i received the updated N55 engine followed by the B58 in 2016, however, the model was rebranded to the 340i. Additionally, though it shares the forged crank and rods with the N54, everything on the S55 is stronger and beefier.

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. AND reliable! This was a great article. It makes hellcat owners cry all day, every day. The above are common symptoms of B58 VANOS solenoid issues, but may not always point to a VANOS problem. However, there is one catch on the B58. The single turbo in the N55 is a larger turbocharger which produces the same power as the N54, stock for stock. 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. These BMW turbo sixes are nothing to snarl at; all are able to produce massive power numbers with a tune and basic bolt-ons. Bam, 45min to an hour for the whole job. Relatively speaking, yes. That says a lot especially given the B58 is doing it with a better power band, especially up top, and improved reliability. Anyone here want to offer an opinion? I do love a straight 6. in. 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. BMW techs dont seem to know how to resolve this. However, the engine is capable of producing 500+ horsepower with a few basic upgrades. Peak power at just around 16psi. BMW really is the Ultimate Driving Machine! Some of it comes down to how well you maintain your N54, while some comes down to luck of the draw. Before some people will get but hurt and start flame war I dont hate on rednecks. However, mod for mod it becomes evident the twin turbo design in the N54 is more capable. Yes, B58 is reliable. Im not sure how many as I was never given any job sheets. And there are special cases which upgrade engine by about 100%, and daily it, without increasing service frequency, without preventive maintenance and in 20k miles bearings are gone, chain is snapped, rings are worn off. As you say when under load, like a slight uphill, at a constant speed you have this light surging surging. Ok, definitely my thought process as well. Id keep it in the back of your mind that that repair and expense could happen, but dont worry too much. Car done 150k now, and pipes that I replaced are still right colour, original coolant pump still works OK and I have zero issues with overheating and coolant temp when idle fluctuates at 110 117 C. From what Ive seen at the dyno where some inexperienced or know better then the test schedule requirements technician used pure water for cooling on endurance or long term emission tests, cooling pump seals and joint between shaft and plastic prop would fail first but on my car it was not the case so far, so as usual T&C applies, your milage may vary. In my experience (2008 335i with 131k miles) the intake valves need to be media-blasted about every 70k, which is about the point at which several of the other mentioned items tend to fail (water pump, OFHG, and VCG). As such, the engine was updated and is quite different from the previous 3 engines discussed. Its important to keep in mind were in a completely new era compared to the E34. If it fails, an upgraded crank hub is definitely the way to go. Turns out coolant was getting into the engine. Completely misread that. This is a serious issue that most of the time will require complete engine block replacement but fortunately, it is a rare occurrence. Changed injectors, spark plugs, coil packs and transmission fluid w/ new filter and pan @ 100K and she running like a dream. Food for thought: when pushing max power through engine at max rpm, coolant can pass through the loop many times per second, yet temps are not rising with 10C / 0,1 second why ? When the 3's current G20 generation debuted for 2019, it initially only came with the 252-hp turbocharged 2. . Thank you for the comment. when removing the reservoir cap, I noticed a bunch of crustiness. If you can pull out the broken filter, inspect and clean any debris. There are countless videos of B58 BMW owners with this exact symptom resulting from a damaged PCV. There's a difference between durability and reliability. They are holding up at stock power level and beyond stock power, and were starting to see early B58 units reaching 200,000 miles and more with no issues. Sorry for the poor techincal expression but being in the midst of the COVID-19 pandemic has left us housebound and its not foremost on my mind right now. We were surprised to find this is not uncommon on other BMW engines, too. Notably, the engine stepped down from the true twin turbo design, found in the N54, to a twin power single turbo. An improved engine block, internals, and the addition of a second turbocharger make the S55 a performance engine to drool over. Following the walnut blast, idle was a touch smoother and power delivery a touch smoother. The B58 timing chain was moved to the rear of the engine. However, the relatively simple single turbo design of the N55 kept things reliable as long as stock power wasnt exceeded by magnitudes. Flush out and refill coolant every 5 years. The B58 is more reliable than the N55. Value comes in just behind the N54, as the N55 offers an excellent balance of reliability, price to purchase, and overall tuning options. Everyone and their brother has done the LS swap and its become boring. Had the well known gasket issues. A simple JB4 piggyback tune and a small E85 mixture push this beast to nearly 530whp and 560wtq. Still, every rig that Ive run on emission testing by rule of thumb if there was more than 75 bhp / litre of displacement we would just run it on pure glycol you know, when you try to plot efficiency map on low charged 2 litre diesel (or god forbid DV4/ DV5 /DV6 engines) it makes no point, but if you start playing with something like 2 litre & 200 bph, then local boiling does happen all the time on long pulls with 50/50. My regret (not even a problem) was that when moving from E to F, BMW matched gearboxes and diffs more closely to stock engine torques, which in my mind was a bit of step back, because you could always count on 3 things with BMW gearboxes in the past 1. they did not provided greatest feedback 2. they always had decent of headroom potential tune 3. every-time you changed gear you felt like you reloaded WW1 full caliber rifle. 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. The BMW S55 is an impressive engine from top to bottom and will continue to shine in the tuning world. the vanos solenoids were a 20min job with a cold engine. Although, Im not sure if they have anything for the M340i. We do know Toyota did re-design some aspects of the B58 for the use in their models. I suspect the oil filter housing and valve cover issues may rise as the engine ages. Has anyone managed to get this problem sorted out yet?And if so could you let me know The B58 has had minor oil leaks, and some report coolant loss, but the internals of this engine have held up over time while providing ample performance. Required fields are marked*. ps. 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. Hi mate,thanks for your reply. It may not display this or other websites correctly. In reality these are a tiny % of the number of engines out there.And usually someone has abused it or skipped a service.I expect the engine to be very reliable and well suited to the vehicle.At least as good as any Defender engine! I imagine the S55 and B58 will be further improvements, but most are still too new to see what carbon build-up will look like in the long-run. Right by the timing chainat the back of the engine. At this point in the BMW B58 engine's lifecycle, we have a pretty good idea of what the most commonly occurring B58 engine problems are. Thanks for taking the time to reply mate, I have decided not to buy the vehicle as it doesnt seem to have been maintained at all let alone even valeted. e92 168k miles (tune about 30% up) 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. Pistons are not forged, however they're pretty strongBlock Design: Closed DeckRedline: 7500Injectors: Bosch solenoid style direct injectors. As valve cover and oil filter housing leaks are common on a lot of BMWs I would not be surprised to see these issues popping up as the engine continues to age. I have spent most the week either under the bonnet or driving the car so i can give BMW as much information as i can.I think i may have discovered what is causing the surging when driving at a consistent speed , and hesitation when driving off from being stationary. Just purchased a 2021 M340. We think the Supra carrying the B58 helps the platform a lot, too. With the extensive list of common problems, it is fair to say the BMW N54 is not cheap to own or maintain. TuningPro.co is owned and operated by 8020 Media. BMW tech found low coolant on the low pressure side. Since then, Ive been wait for Dinans Stage II, III and turbo, but, nada. Good luck with finding the issue with yours. Lets look at both engines in detail to find out why the N55 is not as reliable as the new B58. Yeah I agree with Tazzieman completely. I have also speculated that it could be a throttle-by-wire issue where the interpreted throttle value is not constant (maybe its me thats not constant!!). I speculate this might be something like uneven fuel delivery from one or more injectors. Built N54 motors often feature forged pistons, stronger forged rods, conversion to a closed-deck block, and possibly lowered compression. Don't sweat it if you're only topping up small amounts on occasion. On the forums you can see logs people recorded showing DME demand and the position feedback chasing it. Open-deck blocks and cast pistons are not great at handling extreme boost pressures for long periods of time. Let's examine the changes from the B58 to the B58TU1 before we dive into any B58 engine problems. Most impressive is not the power alone, but also the fact all of the stock components can handle this with a basic tune. It's always the minority of people with issues that shout the loudest. Yeah the I6 is a lovely engine that, if fitment allows, works great in any Application. Thanks! Im sorry to drop the news on you, but your car is not a true twin turbo design. (cold start is just supposed to head up the catalytic filter in the downpipe, so thats why its commonly removed after catless downpipe installation.)e. Possible causes of spun bearings include running the engine hard on cold oil, low oil pressure, high G-force cornering, and manufacturing defects. It is subtle, I havent observed the tachometer following this pulsing. Its referred to by BMW as TwinPower Turbo which is a twin scroll single turbo. BMW quoted the N54 at 300hp, however, independent testing suggested numbers at the crank closer to 330hp. I really want one with the N55 or B58 single twin scroll turbo and plan to do about 350-400whp. Stock Power: 424 HPWorld Record HP: 1150WHP (~1350 crank horsepower!! Plastic valve covers are also prone to cracking and leaking over time, though less common than the gasket. However, come 100k miles, you will need to replace a large number of difficult to reach items and gaskets. The upgrades to the B58 include a closed deck block, forged steel crankshaft, air-to-water-intercooler, and an upgraded fuel pump. VANOS solenoids may be considered a normal wear and tear item. Crank and block should be plenty strong to handle 800+whp. We may receive a commission for purchases made through these links. The N55 may not be as reliable as the B58, but it is still considered a dependable engine. Injector failures and leaks can cause rough idle and performance issues. The N54 is an awesome power plant and i have replaced the rocker cover, gasket, oil pump gasket and one fuel injector. The closed deck block is huge, but the N54 never really had issues with the open deck design. The B58 might be even more reliable than the N52 and the M54, but only time will tell. It cleaned up ignition timing a little bit, too. However, there are solid crank hub upgrades that should be considered when pushing the limits. Ill take it up with the dealership once we are all in better times. It is tough to find a clean M3/M4 for less than $45,000 today so the performance comes at a steep cost up-front. Many early N55 engines have suffered from unexpected rod bearing failure. Thanks for the great read. Second, last night I purchased a 2017 340 with 30k. Conclusion. Has it happened to someone else? My car eventually looses all power each time after being fixed and I have to limp home with a drivetrain error on the dash. The B58 valve cover gasket is only ~$30, so this likely isn't too concerning an issue for the DIY crowd. Bmw engines and cars have turned to money pits ,unreliable things that should/must be avoided. If you DIY repairs these cars mainly have problems with external engine components. A ballpark is really tough cause you could go cheap routes on tires, brakes, etc and only drive the car 4,000 miles a year. Hi the B58 is not the same engine as M4 M4 is S55. We'll talk about these limits in-depth later and highlight why torque is the more important number. I have a 440i with m performance and sound kit during cold start there is shaking in the car I can feel the shaking if I hold the stearing wheel with both of my hands I am not sure what might be causing the problem only have about 25k miles showed to dealer they dint find anything The B58 is a great engine, but the S55 is better. Did this fix the problem? )Displacement: 2979cc (2.979L)Turbocharger: TwinPower Single TurboCompression: 10.2 to 1Bore x Stroke: 84.0mm (3.31) x 89.6mm (3.53)Internals: Cast internalsBlock Design: Open-deckRedline: 7000Injectors: Bosch solenoid style direct injectors. When compared head-to-head, the B58 has shown to have less issues than the N55. My car is going in to BMW on Thursday. This increases performance by. Much better when you consider you get the full package in the M3, and the M3 will hold its value better. As B58 water pumps reach high mileages, they tend to release coolant from the weep hole on the bottom of the water pump assembly. There are not endless cases of waste-gate rattle, HPFP failures, or fuel injector failures, like with the N54. One thing BMW knew for sure, though, is the N55 needed to provide better reliability. The B58 oil filter is prone to shearing at the bottom. Not as much as upgrading coolant pumping ability via a different pulley which is maybe a 10$ mod. Hi Hank, Ive currently been having issues with my M140i. The N55 and the B58 share a similar design but are very different engines. Injectors are getting loud again at 200k so its time to replace them. Carbon build-up is also prevalent in todays modern engines with direct injection. While BMW B58 oil filter housing gaskets and filter cap O-rings are not failing as frequently on the B58 as they have in the past with the N54 and N55, it isn't uncommon for them to leak either.
