N55 water pumps are notorious for their low lifespan. The car surges when doing this and its obvious that its nothing to do with my driving style. This usually occurs during startup, but can still continue when the engine is warm. ps. 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. 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. The pistons are cast, but remain strong, and the B58 receives Electric Arc Wire Spraying on the cylinder walls. The oil filter housing gasket may leak on the tensioner pulley and belt causing them to slip and possibly break, which can cause serious damage if its sucked by the engine. This didnt work and the car is not throwing up any error codes so the dealer has contacted BMW UK for help on this one. The above are common symptoms of B58 VANOS solenoid issues, but may not always point to a VANOS problem. What are your thoughts and experience with the B58? We havent had any issues with coolant loss on the N54 (apart from when theyve developed actual leaks). 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. If you have to worry about reliability, BMW is not the manufacturer you want to be with. e90 200k miles. DIY everything $300 to $750 a year 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). 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. 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. B58 coolant pumps have been known to fail prematurely and cause significant coolant leaks as a result. Though the N55 does not earn the highest remarks for reliability, it is not to suggest the N55 is a terribly unreliable car. A 2017 340i M Sport uses the B58 engine, which is a single turbo. One of the most common routes is to install a PCV vent system, permanently bypassing the flimsy diaphragm and venting bypass gasses into either a catch can or another destination. So much so that I'd prefer it over the N55. Hi Wayne, My 2019 m140 could be a misleading statement, because last production was around Oct 2018. Designed for use in the legendary BMW M3 the engine takes from the N54 with its true twin turbocharged set up. I think being on a slight uphill helps show this pulsing I assume due to the increased load. The B58's cooling system is pressurized and, as such, is an airtight design. Cant wait to compare the BM3 to the Dinan Stage 1. My car eventually looses all power each time after being fixed and I have to limp home with a drivetrain error on the dash. )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. 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. Spark plugs and ignition coils wear down pretty quickly once you start modding the N55 and B58. Copyright 2021 - 2023 BMW Tuning LLC. Im guessing something might be coming up in future Im not sure if any other b58 owners have this or if its common Although the B58 uses similar rubber VCG's, the engine has one advantage. 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. Usually, owners dont report major issue. Just go hard more. Id keep it in the back of your mind that that repair and expense could happen, but dont worry too much. Many issues with their turbo engines. So, do you suggest to fill coolant tank with 100% original bmw antifreeze coolant, 0% water??? Completely misread that. 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. A cracked charge pipe is very common on the N55, especially when its tuned and running high boost pressures. Save my name, email, and website in this browser for the next time I comment. Many B58 owners are experiencing low coolant in the main tank. Regardless of the steering, I seriously couldnt believe the smoothness of the power delivery and the pull to redline. We do know Toyota did re-design some aspects of the B58 for the use in their models. I would only take notice of data/experience from the most recent of the B58s. What kind of HP increase could I expect with the JB4 piggyback tune? Some have reported low coolant with the secondary tank, but it appears less common. From day one of delivery, I have often smelled coolant. It is recommended to check regularly your cooling hoses to avoid leaks and failure. 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. My history with bmw is: The pipe that goes over the radiator was so brittle that not only was leaking, but when I had wrench & beer evening with my old friend it was just cracking in our hands like crisps (or chips if youre from US). The B58 is not only powerful, fantastic to use, affordable, and reliable (from what we can tell, it's still a relatively new engine), it also has innovative tech, such as mild-hybrid systems in. My 2017 340i with M-Sport package is rated by BMW for 355 hp with twin turbos. 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. hopefully BMW will sort this out. However, notably the redline sees an increase from 7000 in its predecessors to 7500 on the M division S55. 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. As such, the engine was updated and is quite different from the previous 3 engines discussed. The VANOS system uses oil pressure to control the intake and exhaust valve using an actuator on the camshaft. 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. Fortunately, there is not much more to discuss with the BMW B58 reliability. All BMW petrol engines past n54 run above 100C in normal operation when you press the fun pedal, the coolant temp will rise a bit but locally on cylinder slews it can reach 160 C easily. Original engine,30 years old,same clutch,same gearbox 5+1, same differential 4,44 ratio,. It is more of a testament to just how good the two remaining engines are. It is also known as a straight-six naturally aspirated engine. 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. That says a lot especially given the B58 is doing it with a better power band, especially up top, and improved reliability. "Natural" is in quotations for a reason. Hardly worth mentioning as it is only a handful. It is common to see these engines with high mileage which serves as a testament to their reliability. Did BMW live up to that reputation? Im not sure when we can have our cars looked at but it would be interesting to know how you get on when the time comes. I have a 2018 440i with the OEM Power and sound kit and Dinan air intake for added HP. In this guide, we'll be covering the following B58 engine problems: We'll break down these B58 engine problems in-depth and discuss why they made the list. The B58 uses two solenoids. 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. . Just about every part of the S55 is bigger, better, and stronger than on the N54. Really appreciate the info. Haha were always down to go harder and push things to the limit. e46 380k miles Not only do they produce significant power, but the engines also do so without much turbo lag and long power bands. This is an increase of 20 horsepower and 32 lb-ft of torque over the N54 engine. We appreciate the positive feedback. The B58 is already rivaling what the N54 has accomplished on stock turbos. BMWs B58 and S55 engines are newer, so more issues may pop up down the road. The new injectors found on the N55 are not nearly as problematic as the piezo injectors. 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. Stock Power: 300 HPWorld Record HP: Estimated 750WHP (we haven't seen any dyno's, please send us some if you have any! It cleaned up ignition timing a little bit, too. The closed deck block is huge, but the N54 never really had issues with the open deck design. My 2017 M240i with 27,000 kms is suffering from the same symptoms. Most repairs at the dealer will easily run over $1,000. N55 is better than the N54, but its just a reliability upgrade. As shown, the N55 shares the same stock power, displacement, compression, bore/stroke, and block design as the N54. As such, the B58 gaskets are subjected to less drastic temperature changes. 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. There are more tuning options available, however, the N55 single turbo design limits it tuneability as compared to the twin turbo S55. Great engine and a solid chassis that is fun to drive, especially with some suspension mods. All rights reserved. However, it's fair to chalk up minor coolant loss to being natural. Although, VANOS work can be done without lifting 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. For that reason, the B58 scores the worst value rating. Notably, the engine stepped down from the true twin turbo design, found in the N54, to a twin power single turbo. BMW used an electric water pump on the N55. 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. 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? Im looking for my first sports car and BMWs seem very nice. 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 . )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. Check your turbo coolant level (smaller of the two reservoir caps). This applies to coolant hoses and coolant connecting flanges. Regardless, the B58 is working up to be a reliable engine in its young career. Lastly, issues with waste-gate rattle were mostly resolved on the N55. Too much trouble. Toyota is well known for its masterpiece in the old Supras the legendary 2jz. The TU1 update is mostly intended to improve emissions. 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. Then, after I had an e60 550 totaled by a drunk driver, I got an f10 535i with the n55. Ive had fuel injectors, coil packs and spark plugs changed. 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. Its that sad with bmw. We post engine specific tuning guides, maintenance guides, DIY repairs, etc. 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. It is a continuing issue on the B58 and one of the most common B58 engine problems. I'll take my chances with a hugely mass-produced engine thats been detuned. Thanks! Guessing you are all semi-auto owners.. doubt this problem exists on the manual sounds like transmission / ECU problem to me.. #. should i stay away? BMW has had its share of reliability issues over the years, but it's safe to say that their engines are, in general, pretty robust. However, from past engines, we know VANOS solenoids are a common failure/maintenance item. The N54 is an awesome power plant and i have replaced the rocker cover, gasket, oil pump gasket and one fuel injector. Stock Power: 424 HPWorld Record HP: 1150WHP (~1350 crank horsepower!! Do you want to get more excitement out of your B58-powered BMW? Ever since the twin turbo N54 hit the markets in the 2007 BMW 335i, BMW has been building on the design of the turbocharged, direct injected inline 6 engine.

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. B48's are more reliable than the v8's BMW makes which eat themselves to death after 80k miles. 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. Has it happened to someone else? Certain G series models began receiving the updated B58TU1 in 2019. Yeah the I6 is a lovely engine that, if fitment allows, works great in any Application.

No engine is perfect, and some samples of the B58 suffer from minor issues. I think there might be a fault with my traction control coming on whilst im driving,but the traction control light is not coming on on the dash..Ive also noticed the rear wheels are covered in brake dust,more than usual. Though, it may be excessive on lower mileage B58's. Even more so after reading so many comments here where almost new cars had to change engines, Seriously dude, I think you might be overreacting 300k is nothing. BMW really is the Ultimate Driving Machine! So much too learn, so little time. Someone knows what is due? Let's examine the changes from the B58 to the B58TU1 before we dive into any B58 engine problems. Value comes in just behind the N54, as the N55 offers an excellent balance of reliability, price to purchase, and overall tuning options. That got lemoned (hpfp issues). Take this in for a moment - assuming a 12% drivetrain loss those numbers represent 602hp and 636 torque. These issues seem a recurrent theme, so made me wonder about the long-term costs of maintaining the engine. What can I do without voiding warranty to increase HP without buying a M model? Our garage currently includes a 2008 135i, 2007 335i, and 2008 535i. Three times this has happened and Ive only just reached 14500 miles. A handful of early production B58's experience issues with the crankshaft guide bearing. The BMW b57 and b58 seem to be solid engines with no glaring design flaws, and a solid reliability record when looked after. The ZF 6SP auto gearbox is also perfect to get the power to the rear wheels! The latest iteration of BMW's iconic six-cylinder inline engine . [/QUOTE]. This is a misconception. Over time, the housing and the electronics inside degrade and fail. 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. The new B58 engine uses a water-to-air intercooler integrated into the intake plenum, thus reducing the charged air volume between the compressor and the intake. Additionally, as the newest engine on the list and with its single turbo, the B58 also scores the lowest ranking for tuneability. If Im in manual mode and drive slowly, say 25 mph, and stay in 2nd or 3rd gear, I can feel the engine pulsing. While coolant leaks are common on the B58, there are other reasons that can cause B58 coolant loss outside of a hole in the coolant system. 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. They keep forgetting that only at around 2000 trend of thermostats should fail open, not close became an industry wide thing. Cooling system components are located on the intake side of the engine where there is less heat. Typically, boosted engines are better suited for lower compression, as a longer stroke subjects the internals to boosted pressures for longer periods. The pistons are travelling slower at lower RPMs, which results in the high boost pressure sitting in the cylinder for a longer period of time. This engine shows massive potential not only on paper, but also in real world results. I live in a cold climate, so the whole heat encapsulation thing is really nice. 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. [youtube=https://www.youtube.com/watch?v=WzgzSnYDvz4&w=660&h=372]. perhaps look for a used Audi 4 wheel drive convertible. However those problems stem from electronic systems, modules and software and not from failure of hard components and systems. Right by the timing chainat the back of the engine. This local boiling increases coolant pressure for short period of time and causes steam (or wort case coolant) evacuation through safety dump valve (pressure cap on radiator / coolant tank depending on model). 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. Now I still experience a bit of coolant loss, but much, much less. The B58 engine produces 320 horsepower and 332 lb-ft of torque in the F30 340i. Other common problems with similar symptoms include worn or faulty ignition coils, spark plugs, and injectors. Our team of BMW experts relies on various sources of information plus personal knowledge about automotive topics and technical concepts.

Ill get to enjoy it a few more days before I say goodbye. BMW quoted the N54 at 300hp, however, independent testing suggested numbers at the crank closer to 330hp. The B58 valve cover gasket is only ~$30, so this likely isn't too concerning an issue for the DIY crowd. Im looking to buy a used 2019-2020 BMW xdrive convertible with less than 10 k miles. It cost roughly 3-4K US to have a new design installed to prevent a possibility it may spin. The cost $60-$65 each and get a few spare clips. Thanks. Hi Adam, Thanks for the information. 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. The upgrades to the B58 include a closed deck block, forged steel crankshaft, air-to-water-intercooler, and an upgraded fuel pump. As such, it can't hurt to replace the valve cover while you're in there. However, this may not be necessary in most cases. Thanks Zach! The B58 is a great engine, but the S55 is better. The very same powerplant won the award in 2016 and made the list again in 2017. AND reliable! Yes Im in the UK John. It makes hellcat owners cry all day, every day. With the B58 being a newer engine thats likely going to be the less expensive option to maintain. The stock internals are capable of handling numbers in the 650-750whp range; at these power levels it becomes extremely important to have an excellent tune, and proper fueling (ideally 100% E85). Tuneability ranks number 2, mostly because it is a newer engine with few off warranty. Not quite sure wether its a B58 or still the N55 thougj.. any ideas? Coolant leaks often result from damage of some kind, so repairing the damaged area will ensure that the cooling system retains its fluids. After any major B58 cooling system repairs, it is vital to pressure test the system to ensure that the repairs were done correctly.
