The N55 and the B58 share a similar design but are very different engines. BMW B58 Reliability. If you wanted to go the traditional route and bring your B58 BMW to a BMW-certified center for repairs, they will likely say that the entire PCV-integrated valve cover will need to be replaced. The BMW B58 is a turbocharged straight-six engine, which began production in 2015. Great article BTW. Ill try to describe what I suspect as a secondary issue. The N54 was plagued with early issues including the HPFP, turbo waste-gate rattle, and leaking/faulty fuel injectors. One of our N54s went 113,000 miles before its first walnut blast. Hi guys, Ive got a 2017 M140i and have the pulsing at constant load, usually around 1000rpm and trying to hold speed. Additionally, it receives the forged crank and rods as with the N54. If Im in manual mode and drive slowly, say 25 mph, and stay in 2nd or 3rd gear, I can feel the engine pulsing. Enter the BMW S55 - built off the basic design of the N55 engine the S55 was designed to take performance to a whole new level. Engines now are far more reliable than in the past. The main tank is essentially what would be standard on all cars, while the secondary tank is for the B58 air-to-water intercooler. Thank you for the comment. Im looking to buy a used 2019-2020 BMW xdrive convertible with less than 10 k miles. Reliability scores the highest marks compared to the N54, N55, and S55. Many issues with their turbo engines. It is subtle, I havent observed the tachometer following this pulsing. Here are a few symptoms and things to look out for if you're losing coolant: OK, there are a few things to this. Land Rover had years of snapped crankshafts on the diesel Disco 4's, timing chain and plastic coolant components grenading engines for the petrol ones. Two of our N54's are nearing 120,000 miles on original VANOS components. 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 cost $60-$65 each and get a few spare clips. VANOS solenoids may be considered a normal wear and tear item. Deposits can cause misfires and power loss. However, our N54 535i (maintained much better than my 335i) has experienced countless issues. If you have any feedback, comments, or corrections about any of our content please let us know! Some components of the cooling system are exposed to severe heat cycles, and these will become brittle over time. What are your thoughts and experience with the B58? . Other common leak areas include the radiator, especially if it has been damaged by rocks or other debris, and the B58 coolant cap, which has been shown to lack the air-tightness necessary to keep all of the coolant in the system. 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. Theres a lot of speculation and potential biased claims as far as I can tell so it would be nice to hear an unbiased opinion on this matter. Replace valve cover gasket and oil pan gasket at 160K. You must log in or register to reply here. Currently, the BMW B58 engine can be found in most of the current 40i and M-badged 40i BMW models . Of course, we are biased towards BMWs here at BMWtuning.co, but we fell in love with these modern turbo BMW engines for a reason. Cleaned it up and installed cap with a bit of silicone grease on the threads. Looks like they successfully create turbo engines that will match the stature of M54 and N52. My car is going in to BMW on Thursday. We did not include that as we do not consider carbon build-up an issue. Ive had fuel injectors, coil packs and spark plugs changed. Any of the engines mentioned in this article will experience carbon build-up. Considered my car is stage 1 tuned. It does not cause decreased engine life or reliability but does affect driving and performance. document.getElementById( "ak_js_1" ).setAttribute( "value", ( new Date() ).getTime() ); Absolutely excellent comparison, Zach. Your comments are welcomed. Could you give me some advice about this problem? Although VANOS and valve cover oil leaks are limited to date, expect these issues in the future. However, there is one more thing. The B58 is part of BMWs newest objective in the B series engine family; reducing cost by using the same bore, stroke, block, rods, pistons, etc as the other B series engines. As such, it can't hurt to replace the valve cover while you're in there. Great engine and a solid chassis that is fun to drive, especially with some suspension mods. Just go hard more. There are countless videos of B58 BMW owners with this exact symptom resulting from a damaged PCV. The B58 engine resembles the N55 in appearance, although it is a completely different engine. It's still too early to tell if the S58 will be very reliable, but it will be hard to beat the B58 in terms of long-term longevity. The BMW B58 engine is a remarkable one. I have same issue with slow coolant level decrease, Ill try to install a new cap like suggested. 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 ! 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). Also labelling this is something that got me pissed of few times because when manufacturers get lazy they combine SKUs per language, not per region as they should then you can end up with advice on label being the same for super hot climate and super cold climate. Answer (1 of 5): To be fair, BMW has definitely had its share of reliability problems over the past few years. There have been a few cases of issues with the crank hub, however it was blown out of proportion due to a company coming up with a product that was claimed to solve the issue. Should I continue looking for a used BMW or The engine still has not seen significant tuning and aftermarket development, so it is tough to put a number on the upper limits of the engine. Agree with you both there Tazzieman/Spjnr. This was a great article. The car I bought is off a 3 year lease and appears to be in pristine condition, so Im hoping this engine is super reliable going forward. If you get a downpipe and aftermarket tune youll definitely want to remove the cold start function. It has honestly amazingly smooth power delivery and sounds better. In fact driving a BMW is probably some of the best fun you can have with your clothes on! Crank and block should be plenty strong to handle 800+whp. (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). Soooo if you have some noise under load best record it from engine bay. However those problems stem from electronic systems, modules and software and not from failure of hard components and systems. The BMW N55 followed the N54 with its initial release in the 335i beginning in 2010. 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. We are hoping to soon add an F80 M3 and F82 M4 GTS. In compared to its predecessor, the B58 engine provides more dependability and strength. Really appreciate the info. It cleaned up ignition timing a little bit, too. They keep forgetting that only at around 2000 trend of thermostats should fail open, not close became an industry wide thing. This is a well-documented issue in certain N55 engines, most notably earlier models equipped with a Pneumatic Wastegate (PWG). Has it happened to someone else? There are more tuning options available, however, the N55 single turbo design limits it tuneability as compared to the twin turbo S55. Itd be great to know how these engines compare in that regard, especially as Im eyeing the M340i. [youtube=https://www.youtube.com/watch?v=WzgzSnYDvz4&w=660&h=372]. It manages a respectable 322-382hp and 332-369 lb-ft from the factory. BMW tech found low coolant on the low pressure side. Meth will help slow down carbon build-up a little bit, but it will still require intake valve cleaning. Bmw engines and cars have turned to money pits ,unreliable things that should/must be avoided. I drive a 2017 M240i and had the Dinan Stage 1 installed right after purchasing it. Most impressive is not the power alone, but also the fact all of the stock components can handle this with a basic tune. Its a lot of extra heat and stress on these engines. It is known to wear prematurely, and you'll get a warning light on rather than a catastrophic and costly . Thank you. Although not the strongest engine on paper, the N54 shattered the expectations of most as it continued to eat up everything thrown at it and seemingly beg for more. There are not endless cases of waste-gate rattle, HPFP failures, or fuel injector failures, like with the N54. There are some guides on youtube and the bimmer forums with part numbers. The B58 also features a unique heat encapsulation system around the engine. There are a few notorious issues in the N55. BMW Reliability Most Reliable BMW Engines. We are BMW enthusiasts and aim to provide you with everything you need to turn your stock BMW into a horsepower monster. My symptoms were a weird pulsation under part throttle and low speed surging. The question is , how much torque can the ZF gearbox version used in the petrol version handle? BMW UKS reply was change valvetronics and re-programme. That got lemoned (hpfp issues). Solenoids are relatively inexpensive and easy to replace. Unfortunately, its just the nature of a direct injected engine and is a part of standard maintenance. Not sure which car you refer to when you say single turbo. 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. Hello, I own F20 120i 2018 with B48 engine (184hp). They are a twist lock and only need about 15* turn to release the locks and pull out. Disintegrated oil filters pop up frequently, but are not serious in most cases. Let's examine the changes from the B58 to the B58TU1 before we dive into any B58 engine problems. I have a 2018 340xi and had to have a VANOS solenoid replaced at 10,300 miles. Our garage currently includes a 2008 135i, 2007 335i, and 2008 535i. Experience something very similar with a 2018 M240i. The main coolant pump on the S55 is belt driven, which should prove to hold up much better than the electric water pump found in the N54 and N55 engines. Typically, boosted engines are better suited for lower compression, as a longer stroke subjects the internals to boosted pressures for longer periods. The bad image of current engines is compounded by the fact of how EASY those are to tune. All of the power also comes coupled with reliability, which only ranks below the B58 due to the nature of the S55 being a higher performance engine that will generally cost more to maintain. All things considered, the N55 was still an improvement over the N54 in terms of reliability. I imagine a lot of (even most?) Ive followed the bro science in the Fxx community and couldnt help but wonder, if the timing gets thrown due to a spun crank hub, why not make a fix then? Hi Adam, Thanks for the information. Hopefully, it's not as bad as the below image. Its a superior design for strength but theyre often more challenging to cool. Woodcliff Lake, NJ - Jan. 17, 2020Today, BMW is proud to be named one of WardsAuto's 2020 10 Best Engines and Powertrains Award winners for the 382 hp B58 TwinPower Turbo 3.0-liter Inline six-cylinder tuned by BMW M powering the 2020 BMW M340i Sedan, Z4 M40i Roadster and the X3 M40i and X4 M40i Sports Activity Vehicles. Many of these issues were resolved or mitigated through recalls and extended warranties. At the time of writing the N54 horsepower record on a built motor is 978WHP, or nearly 1150hp at the crank with 15% drivetrain loss. Hi Hank, Ive currently been having issues with my M140i. On the forums you can see logs people recorded showing DME demand and the position feedback chasing it. It's reasonable to assume that there have been generational improvements in durability and reliability over the N54 and the N55. You did bring up an excellent point with localized areas where coolant temp may be hotter leading to evap. Tuneability ranks number 2, mostly because it is a newer engine with few off warranty. B58 Reliability: I hear it will be good long term. 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. B58 to N55 Comparison. Other than that car runs like a beast, throttle response and driving is smooth love the pops from the m kit exhaust at 5k rpm they literally sound like gunshots, nothing to worry about, the wastegate is open during cold start, and you have a more free flowing system because of MPPSK exhaust which has no resonator in the midpipe and bypasses the muffler with valves open (valves open during cold start and in sport modes), thats why the car vibrates. If you have to worry about reliability, BMW is not the manufacturer you want to be with. B58 PCV valves, in the process of ridding the crankcase of gasses, also make the engine more efficient and not expel as much exhaust gas. Cant wait to compare the BM3 to the Dinan Stage 1. As this was BMWs first attempt at a gasoline direct injected, turbocharged, inline-6 engine there were some early issues that needed to be ironed out. Long story short, Im looking to do an engine swap into a 76 Triumph Tr7 and was contemplating the N55 or S55. BMW's B58 and S55 engines are newer, so more issues may pop up down the road. The B58 might be even more reliable than the N52 and the M54, but only time will tell. The B58 is more reliable than the N55. Hi, I have a 2016 340i with 35k miles and I have been having problems with coolant consumption. 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. Proceed with the oil change as normal. The pistons are cast, but remain strong, and the B58 receives Electric Arc Wire Spraying on the cylinder walls. Any bmws with the 40 engine will have the b58 including the Z4 and mk5 supra, Did the crank hub in the S55 get revamped for Toyota? 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. Which engine is more reliable, the N55 or the B58? The B58 engine is the successor to the N55 engine. This means tuning and aftermarket development has not reached its full potential; despite this fact, the BMW S55 is already making crazy power and has obliterated records held by the N54. Now I still experience a bit of coolant loss, but much, much less. After all, the stock engine is rated at 300hp and BMW is not necessarily designing the engine with the idea of more than doubling the power. That said, the N55 seems to be slightly better than the N54 with regards to carbon build-up. Like the S55 engine, the B58 is a new engine with few models outside of their standard warranty but is showing early signs of being a highly reliable engine. Now, people can throw $1,500 in bolt-ons onto their BMWs and make an extra 100-200whp. Still a sound improvement for the B58. The B58 replaced the N55 and was launched in the F30 340i.. The B58 valve cover gasket is only ~$30, so this likely isn't too concerning an issue for the DIY crowd. But sometimes, my engine just doesnt want to start. Im experiencing the same as you when the car is under load. Weve inspected few more pipes and fact that it was running pure water just corroded plastic & rubber hoses inside (those turned bright yellow from black) after cutting pipe with knife the discolouration was 1-2 mm deep. Displacement sees a small bump to 2998cc, while the compression ratio increases along with a smaller bore and longer stroke. 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. Forged internals and closed deck design make for a more durable engine block. Guessing you are all semi-auto owners.. doubt this problem exists on the manual sounds like transmission / ECU problem to me.. #. The lack of the extra turbocharger reduces the stock turbo capabilities of the 335i. 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. This does help a bit with longevity. Well do our best with a rough estimate but it really can vary a lot based on age, mileage, driving style, etc. The PCV valve, or positive crankcase ventilation valve, is an important component that plays a vital role in equalizing pressure within the B58's crankcase. However, you may make it well past without issues. Guess where the VANOS components reside? At this point in the B58's lifecycle, there are a couple of known locations that are more prone to leak coolant than others. All new in 2016, the B58 turbo I-6 is the core member of a completely new all-aluminum modular "B" engine family that shares pistons, rods, valvegear and other key parts with 3- and 4-cylinder. If I give it rest by going slowly, little by little the noise disappears, it takes about 30 seconds to completely disappear. . Ok, definitely my thought process as well. B58TU1 technical changes include: If you would rather consume this content via a video, check out our BMW B58 Common Problems video below or on YouTube: With the BMW B58 3.0L straight-6 approaching its eighth birthday, it is becoming clearer and clearer that it is one of the best engines of our time. Same with the N54 and E9x chassis. The best one worth having and mentioned is S38B38 from the E34 M5 car. 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. The first indicator of an issue was a check engine light. Outside of that, meth definitely has some great performance benefits. Merry Xmas all from Chris in Canberra, Australia! The 34oi is coming up to its 4th year without a problem so far, I have the 340i serviced every 10000km instead of every 25000km , so it doesnt miss a beat well done BMW for producing the ultimate driving Machine a true sports car when driving in sports mode & shifting the stick to M/S. It basically has a more aggressive tune from the factory. 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. Ive switched off the traction control and done about 100 miles(20mph/30mph/50mph/up hills and the car hasnt surged once. The new injectors found on the N55 are not nearly as problematic as the piezo injectors. Disclaimer: This site contains affiliate links. One dependable BMW engine, the N52 inline-6 featured in the E90 325i, 328i, and 330i, has already been covered in detail. 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). Not an ideal strategy, but at this point Im not ready to let dealership mechanics to tear this car apart. The BMW B58 engine can handle around 600-650whp and 550-600wtq on the stock block and internals. Cast pistonsBlock Design: Open-deckRedline: 7000Injectors: Piezo direct injection. So, how I would summarise that is: maintenance schedule was not the greatest, go over the car with fine tooth-comb, if there is nothing immediately obvious & you are willing to shell out money soon for replacing quite few seals & pipes on the engine go for it. Im not convinced there isnt a secondary issue. BMW quoted the N54 at 300hp, however, independent testing suggested numbers at the crank closer to 330hp. Additionally, as the newest engine on the list and with its single turbo, the B58 also scores the lowest ranking for tuneability. Only tool I needed was a small flathead screwdriver. 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. Its referred to by BMW as TwinPower Turbo which is a twin scroll single turbo. Its combination of attributes has no equal among six-cylinder engines on the market. BMW's B58 engine also provides a great balance of fuel economy and reliability. Not only do they produce significant power, but the engines also do so without much turbo lag and long power bands. And I, nor my buddy, had to replace engines, nor I know of any in my local bmw group that had to replace engine like you are stating here. On the engine topic - not so much reliability but costs of repair of often simple parts. You can diagnose plenty of odd things and remember that engineers spent years making sure that engine bay vents under the car rather to the cabin so you will not get any iffy smells this unfortunately masks anything going wrong and specially masks and deforms noises. My 2017 M240i with 27,000 kms is suffering from the same symptoms. Hi All Fortunately, this does not seem to be the case apart from the random, flukey issues. 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. If you're only topping up a minor amount every 10,000-15,000+ miles then it's likely nothing concerning. Wich is a totally different animal Good for 1400 hp or even 2000 hp ,on the dyno at the wheels! This can result in oil-rich gasses being pumped into the intake manifold. Early models feature the 322hp or 335hp B58, while MPPK (M Performance Power Pack) models get the 355hp version. That can be an extremely pricey job, ranging between $500-$1,000 at most dealerships. We are hoping to soon add an F80 M3 and F82 M4 GTS. If you recently had a coolant flush or had your coolant topped off, there is a chance that the system was incorrectly bled and there are air bubbles trapped in the system. Peak power at just around 16psi. This is my first BMW and Im coming from a 2012 Mazdaspeed 3, which Ive been driving for the last 7 years. Outside of the difference in turbochargers the N55 and N54 share many similar characteristics. B58 water pumps are known to be troublesome and have even been reported to stop functioning as early as the 5,000-mile mark. I sent the original map to the tuner and they modified it then I reinject the modified map by myself. It's always the minority of people with issues that shout the loudest. Yes, B58 is reliable. Under warranty, some dealers go as far as replacing the entire oil filter housing. The latest iteration of BMW's iconic six-cylinder inline engine . Totally agree. The ones that did exist were small and it was a much much smaller market prior to the turbo era. Would a swap to s55 be ruinously expensive and difficult? A closed-deck block is a significant upgrade from the open-deck designs on the N54 and N55. Developed & Maintained by Never put excessive loads on the engine when its still cold. Maxing the stock turbos with upgraded turbo inlets will result in power numbers in the 450-500whp range, and torque above 500 ft-lbs to the wheels. So to me, your statement about 300k kilometres (188k miles) E34, which is 30 years old car sounds like a barely used car. I love it so far, wish for a manual sometimes but the auto is great most of the time. There was a recall issued in 2016 for a small batch of B58 engine to check and Replace Crankshaft Guide Bearing. All rights reserved. The cap leaking does seem to be a part of the cause. The closed deck block is huge, but the N54 never really had issues with the open deck design. Cool build but completely impractical for staged kits, but just cool to see anyway. BMW replaced it under warranty as one would expect. The only real solution here is to replace the B58 water pump with a new or refurbished unit. I add small amount of coolant from time to time, but nothing crazy. Im new to all of this. However, a couple quick notes that are imperative to keep in mind: B58 engine is same used for for M4 with greater HP. Completely misread that. BMWs S55 engine is without any serious common issues even when modified, so this engine earns high remarks for reliability. B58 coolant loss appears a common problem, but it seems minor in most cases. Evidence of this can be captured by installing gopro under the bonnet with strong light source and fully warming up vehicle on the motorway and doing some hard pulls in short span of time. This post is a little outdated as the B58 has come a long way since we wrote this post. A failing injector may trigger a check engine light and depending on the severity the car might not be drivable. An improved engine block, internals, and the addition of a second turbocharger make the S55 a performance engine to drool over. (4.2 l)My '06 TJ has the 4.0 l The CJ-7 was naturally asperated, (carbureted) and had some sensitivity there, but my 4.0 l is fuel injected and has been rock solid! You may notice burning oil smells in the cabin. Conclusion. You should replace the B58 oil filter with every oil change, anyways. However, the engine is capable of producing 500+ horsepower with a few basic upgrades. Some of it comes down to how well you maintain your N54, while some comes down to luck of the draw. Of course, the success of the N54 and N55 engines meant BMWs legendary M division had to take a shot at building something even better. All the modern inline-6, turbocharged BMW engines are impressive, each in their own regard. My question is what are the running costs for them (a ballpark mainly). Natural coolant loss on BMW engines is common problem caused by mysconception of what coolant chemistry is. Excessive oil consumption is another big one that can alert you to this issue. Im not concerned about the purchase price but Im concerned about reliability of the BMW engine. 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. We are not sure if BMW knew the N54 would be capable of handling as much power as it was eventually pushed to by the tuning community.
