Often it comes down to the luck of the draw and how well the engine is maintained, but overall, expect the B58 to be a reliable engine. Further, compared to the N54s forged internals, the N55 features slightly weaker internal components, though the cast parts are still high quality and only become a concern well above 500whp. However, it's worth monitoring as the B58 ages. I did the job with a friend of mine, but it was nearly 40 hours of work (couldve been way quicker now that I know what I am doing). Certain G series models began receiving the updated B58TU1 in 2019. Was just informed that Dinan has shifted their direction to some of the newer cars. Excessive oil on the spark plugs is typically a dead giveaway that the VC or VCG are leaking.

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. Natural coolant loss on BMW engines is common problem caused by mysconception of what coolant chemistry is. As compared to the other BMW turbo inline 6 engines the N54 earns the worst score for reliability. It is usually just one of the sensors but I would do both anyway. 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. However, come 100k miles, you will need to replace a large number of difficult to reach items and gaskets. Totally agree. 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. Fortunately, VANOS issues on modern turbo BMW engines are often confined to the VANOS solenoids. Don't panic and waste money tracking down an issue that may not exist. Don't sweat it if you're only topping up small amounts on occasion. N55 water pumps are notorious for their low lifespan. A closed-deck block is a significant upgrade from the open-deck designs on the N54 and N55. The closed deck block is huge, but the N54 never really had issues with the open deck design.

TuningPro.co is owned and operated by 8020 Media. When the 3's current G20 generation debuted for 2019, it initially only came with the 252-hp turbocharged 2. . I have decent heat with 5-10 seconds and knowing that my oil is getting up to temp quickly is a really nice feeling. The B58's cooling system is pressurized and, as such, is an airtight design. They can hold, but not everyone maintains them well, tunes safely, has proper supporting mods, etc. I have had all 3, I had a 535i e60, with the n54. my buddy still has: I really want one with the N55 or B58 single twin scroll turbo and plan to do about 350-400whp. Copyright 2021 - 2023 BMW Tuning LLC. It cleaned up ignition timing a little bit, too. Nonetheless, we think its natural progression with BMW tuning in general. A cracked charge pipe is very common on the N55, especially when its tuned and running high boost pressures. 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. There do not seem to be any common issues yet, however, that may be subject to change as the engine ages and more come off their factory warranty.

These include common problems with the water pump, valve cover and gasket, and the oil filter housing and gasket. This can result in oil-rich gasses being pumped into the intake manifold. I took my car to the dealership, they did pressure system check, but they didnt find any leaks. Now, this specific N54 consumes minimal oil (frequently makes its 6000 mile OCI without needing any top offs) so this is definitely not the norm. Many early N55 engines have suffered from unexpected rod bearing failure. However, it wasnt as drastic of an improvement as some say.

Ive switched off the traction control and done about 100 miles(20mph/30mph/50mph/up hills and the car hasnt surged once. 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. Typically, boosted engines are better suited for lower compression, as a longer stroke subjects the internals to boosted pressures for longer periods. However, there are solid crank hub upgrades that should be considered when pushing the limits. The talker a 6th gear I can find the better. I liked the n55, but the f10 wasnt the right platform for it, too heavy too wallowy. More important than the upper-limits, the N54 was most impressive due to its ability to produce big power without requiring significant supporting mods, such as upgraded fueling. Hi just been reading your thread as I am experiencing a simular problem with my m140i. Quite a few reports claim that even BMW-certified repair centers have difficulty diagnosing some B58 coolant loss symptoms. Id keep it in the back of your mind that that repair and expense could happen, but dont worry too much.

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. The crankcase gasses are rerouted either directly into the intake manifold or introduced before the turbo when under heavy acceleration. 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. We did not include that as we do not consider carbon build-up an issue. Guessing you are all semi-auto owners.. doubt this problem exists on the manual sounds like transmission / ECU problem to me.. #. e91 189k miles 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. Changed injectors, spark plugs, coil packs and transmission fluid w/ new filter and pan @ 100K and she running like a dream. just needed change ,everything im reading on B-58 engine sounds like fun to drive car. Enjoy the car and Merry Christmas to you as well! My history with bmw is: 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). 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 Yeah - a straight six is a beautiful thing. Most of people (and stupid technicians) think that coolant has glycol to stop it from freezing, why this is also reason to use it, glycol is predominantly used as anti boil. These leaks commonly develop around 70,000 to 100,000 miles. Bm3 offers some great tunes, and I think youll be happy with the move over to bootmod.

Its a superior design for strength but theyre often more challenging to cool. Although, the single turbo will likely limit its capabilities without upgraded turbo(s). 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).
