Good evening, I am writing to try to get info, and outcomes from anyone who.may have experienced the same issue I am having. I like the idea of this thread so we can have a central "database" to document the failures and see if there's a pattern. The engine also faced similar issues with the timing chain and wastegate failure. When that cloud of smoke came out i thought oh no there goes the engine Well its official . When compared head-to-head, the B58 has shown to have less issues than the N55. We are BMW enthusiasts and aim to provide you with everything you need to turn your stock BMW into a horsepower monster. We can only rely on experience.Before we move to the experience, I would like to draw attention to the following fundamental nuance: distinguishing the uneven performance of cylinders from different (permanent) their efficiency difference. Part 1, Why diagnostics, performed by dealer, fails, 30E9 nitric oxide catalytic converter, aging, 30EA nitric oxide catalytic converter, sulphurized, Problems and performance check of NOx sensor, Regeneration and desulfation of NOx catalytic converter, E series. The pistons are cast, but remain strong. . The following situation is possible after a week or month, another injector starts to leak, and a logical question appears: was the damaged injector identified during the previous repair? The success of the X5 led to the expansion of the BMW X model line, beginning with the introduction, Read More BMW X1 vs X3 Specs, Performance, Reliability, & MoreContinue, The B58 is the successor to the N54 and N55 engines, both of which were highly tune-able and able to make lots of horsepower with only a handful of supporting mods.

We wrote an article here about the most common problems on the B58. Please ensure your correct model is selected. We dont really love that idea. Add to cart. A PUMA case was most likely opened for engine failure (these are rare). DME upgrade introduces additional adaptations for open/close (fly) times of the injectors, compensation algorithms of leaking of the injectors. Part 1. There are tons of "scoring threads" on this forum, mentioned on tuned and stock engines. Its also doing so with greater overall reliability. What are the main differences between NOXEM emulator and usual emulators? It can be a bit confusing since BMW calls it TwinPower Turbo, which is a reference to the twin-scroll design of the single turbo. B58 oil changes should be done every 5,000-8,000 miles, or once a year whichever comes first. Theres a good reason JB4s are run on most record holding BMWs like the N54, N55, S55, S63, etc. The B58 has 24 valves. However, LL14FE oils are designed with fuel economy in mind. Are there any ways to see the health status of the NOx system?, B58. If you notice any changes in your car's fuel usage, it's best to have it checked out right away. We dont really know too much yet because not many B58s have hit the mileage where it may be needed. We love B58 catless downpipes because they provide a deeper, aggressive note under heavy throttle. For many years already, the actual (last) release of the injectors: 11. Due to injector problems, these engines were a nightmare for BMW AG. Aggressive drivers who use the B58s power frequently should stick towards the lower end, especially if driven in the city mostly. Also, these engines didnt have a Stratified charge. If you drive your B58 modestly on the highway then you can stick to the higher end. 2 and No.5 is the smallest.Why does such a situation form? However, the JB4 can be stacked with a flash tune, known as a back-end flash. Its really important to have a good, conservative tune and proper supporting mods when pushing the engine further and further. No scoring problems on my tracked car. N43/N53 operation modes. N55. Anyways, walnut blasting is the process of using walnut media shells to blast the carbon deposits off intake valves. For a better experience, please enable JavaScript in your browser before proceeding. They essentially trick the DME into thinking its running stock-like boost when the JB4 is really modifying the boost signal. Uneven running. A Stratified charge doesnt reduce fuel consumption? Dealers attempt to sketch you for EUR 6000? Outside of that, engine problems are still rather unknown and uncommon. The B58 holds 6.9 quarts (~6.5L) of engine oil. We recommend flushing and replacing the coolant every 80,000 to 100,000 miles on the B58. Chill out. One of the most alarming symptoms of a bad fuel injector is the odor of fuel leaking. BMW B46/B58 vs B46TU/B58TU. Thats what weve run on all of our BMWs with great success. Posts. MG Flasher Now Supports Late Model B48 MINIs!

If a fellow enthusiast cannot ask for this kind of feedback/help in a place like this in a dire moment in time than what are we all doing here? Why I put an accent to is available? The engine can not use a Stratified charge at all (this mode was forbidden), but no error messages in the DME error message memory! Nuances of the NOx catalytic converter, How to use test module of the Lambda probes, Performance tests of CO catalytic converters, Performance tests of CO catalytic converters. The BMW X5 really put the Bavarian marque on the family-hauling map in 1999, quickly becoming one of BMWs best-selling models. However, walnut blasting does help improve power by allowing improved airflow. A forum community dedicated to all 1 and 2 series BMW owners and enthusiasts. Drives: 2011 E92 BW. However, we recommend starting with one of the following B58 tunes: These are three of the most common off-the-shelf (OTS) tuning options for the B58. Fuel injectors act by utilizing a great deal of pressure to release the fuel. Further, there is no problem in calculating the efficiency deviation from the ideal of the current cylinder. Ahhhwalnut blasting. Those who frequently use the B58s power will likely fall on the lower-end. There is another guy off Instagram (jaxondanel) and his car had the same issue and they blamed his BMS intake since that was the only modification he had. To become a vendor visit: https://bit.ly/ss-vendor-apply. The N54 takes the cake in regards to horsepower capabilities, but it had many engine problems as a result.

Still confused. Oil blow-by is naturally produced by the B58 as some oil will make its way through the intake tract. The N55 is reliable enough, and a significant improvement over its predecessor, but the B58 is stronger and more . The labor work costs 50$ to 150$, depending on the workshop. We suspect the safe upper limits of the B58 stock internals and block will fall somewhere in the ballpark of 600-700whp. Dirty intake valves (walnut blast needed). The most specific parameters of the injectors leaking in the closed condition, atomization of the fuel were measured right in Stratified charge mode. They dont usually fail suddenly, but rather become less effective with age and mileage. We recommend opting for an open intake like the BMS option. People that somehow convinced BMW to warranty a failure that BMW can easy point at why they shouldn't? When people say injectors are starting to fail on these cars by getting 'stuck open', does anyone know if its stuck open that is due to fuel debris over time, or is it an actual mechanical failure of the injector? Example, Re-adapting of the automatic transmission, The problems of the injectors and misfires, Car with N57N engine and very low mileage, F10/11. Dont worry the hot air intake myth has been debunked many times. Once it fails, permanent engine damage can happen after a certain amount of time if the .

Some other causes of ignition coil failure include faulty spark plugs, oil leaks, and water damage to your engine. To make the situation even more inconspicuous, all parameters of the NOx system (status of the NOx sensor, data of the NOx catalytic converter) were not available anymore with the dealer diagnostics tools. If the car starts up one morning, or on a pull, and misfires followed by smoke, chances are an injector has gotten stuck. But did not have any other issues. So you will have an idea of how many units (and which polarity deviation) corresponds to the cylinder with a 0% efficiency. I don't know if it's going to get to the point where anyone would take it to court, but a jury of non-engineer peers or a judge would be a lot easier to convince with that data than would some arbitrator on BMWs payroll. A lair of excellent specialists. Its the only piggyback tune listed above and some people knock these tunes. Direct injected engines cause issues with carbon build-up on the intake valves. Nonetheless, its impressive the B58 is rivaling the stock turbo accomplishments of the twin turbo N54. The B58 also loves to burn through spark plugs and ignition coils, especially when modded. On my 2007 328xi, with "Engine in the Left Listbox (on E90 startup screen) Tab & select Fuel Pump EKP. Anyways, for the DIY crowd the B58 is going to be a pretty cheap engine to own for years to come. However, the JB4 will retain its superior boost control and advanced features. 207. Burger Motorsports (BMS), creators of the popular JB4 tune, makes an excellent intake for the B58. Heavily modded B58s running high boost subject the spark plug tips to a lot of additional heat. Its a vague answer, but theres really no perfect answer. The TU1 update is mostly intended to improve emissions. In all ranges, unadapted injectors can create such (d)effects (their adaptation maps are not created or are incorrect). Its also not terribly expensive, especially for the DIY crowd. Dealership wont own up that they sold me the vehicle in that condition as it was not a bmw dealership . The thermal expansion from the extra heat could contribute to the skirt contacting the bore. Originally Posted by G_B58. Notes. Stratified charge: disabled. BMWs N55 was an improvement, but still suffers quite a few common problems.

It manages a respectable 322-382hp and 332-369 lb-ft from the factory. Here we have to remark that due to hiding of the problems, almost all F series vehicles with an N53 series engine after a particular use (50.000 km+) were not using a Stratified charge. Its a quality oil for a good price. Theyre both enthusiast cars that deliver great performance, handling, and driving experience. What are deviations from the ideal allowed? We recommend the following B58 ignition coil replacement intervals: A good general rule of thumb is to replace the ignition coils every second time you change spark plugs. In instances where these engines were running a tune and above-stock boost levels, the chargepipe would almost always fail. 3. 4. Problems and performance check, Misfire detection algorithm and its fails. Part 2, Persistent vibration in Homogeneous mode. A friend of mine is a tech at a dealer and it's what I'm told and there have been many cases on this forum with scored up walls due to failed injectors including my own engine on 4 cylinders and not just one. Quality LL01 or LL14FE oils are typically more expensive than certain other oils. . Where could be the problem? Use tab to navigate through the menu items. Rough run. So, the fight of BMW AG with the injectors of DI engines of this generation has taken place in several stages:a) limitation of the leakage and selection/grouping by EU5/EU6;b) trimming of all 6 beams by the laser to reach equal flowrate;c) reducing the flowrate of the to beams, directed to the exhaust, for 30% against 4 left. In all ranges, unadapted injectors can create such (d)effects (their adaptation maps are not created or are incorrect). Dont overlook this basic maintenance item on the B58. As with many turbo BMW engines the B58 loves to burn through spark plugs. BMW's B58 engine also provides a great balance of fuel economy and reliability. We broke down the rough engine maintenance costs above. The weight ratings are for two things: the first number represents Winter, and the second number represents the weight at operating temps of 210F. Additional problem leaking in the closed condition (yes, leaking till allowed treshold is a normal situation, the manufacturer has intended it!). Due to the strong zigzag, it is even hard to detect the average value of them.Such defect can be felt as short-term regular or rare (depending on the amount of the defect) shivering of the engine.Cause of the defect misfires or unregular bad fuel burning. In these engines, the same injectors as for N55/N20/N26 are used. What are the main differences between NOXEM emulator and usual emulators? Typically, FBO on the B58 refers to a tune, intake, and downpipe. Obviously, cylinders No.1 and No.6 have the best supply of air and fuel. F series. RK Autowerks B58 Port Injection Kit - B58 Gen 2. Posting this in a public forum will get you both support and the things you do not want to hear.

A fuel leak can be scary for drivers . We recommend running a 0W-30 weight oil on the B58. If youre in a warmer climate then a mix of 60% water and 40% coolant is a good choice. Part 2. Unit of cylinder mechanical efficiency measurement: scale 2.As we see, the red and yellow curves are fluctuating around 0.0;Both blue curves are fluctuating around +3.0;Green and grey curves are fluctuating around -4.0.Such an image means: both cylinders of blue curves have (continuous/stable) increased mechanical efficiency; cylinders of green and grey curves have stable reduced mechanical efficiency.According to the legend of the curves:a. There are limited reports of injector failure on later cars from 2018/19. Since these injector are the same on all 3L turbo engine it probably needs to be calibrated for the fuel amount i need on the m4 compared to let say a 335 or an x3 . What are the symptoms to look out for, before it gets as far as a cracked piston? The BMW B58 entered production in 2015. MSV70/80, MSD80 and Lambda probes. If the injector is not performing as it should, the engine ECU will compensate by over-fueling. Throttle and accelerator pedal. That won't work. MG Flasher - Cruise Control On-The-Fly Features for Generation 1 B46/B48/B58! What exactly this is already the next step in the diagnostics.Such performance of the cylinder causes the diesel car feeling permanent vibration. Most are limited to 155mph from the factory. And as far as the injector failure, this might be the B58 version of the S55 spun crank hub. The efficiency of cylinders No.3 and No.4 is average;c. The efficiency of cylinders No. B48/B58. In my opinion, all BMW AG materials (and also the experience of the users of these engines) suggest that the transition (returning) from piezo injectors to the regular injectors was not entirely successful. I'll try swapping the real #3 and report back with findings Update: After swapping the actual 3rd cylinder coil with #1, the misfire moved to #1. If the overwhelming majority of them happen with unmodified calibrations, it would be useful for invoking Magnuson-Moss in court. 1) B58 Engine Problems - B58 Coolant Loss. Probably. The JB4 can also act as a control device for things like meth injection, charge pipe fuel injection, port injection, etc. Modestly, highway driven BMW B58 engines may even get a bit more life out of the spark plugs compared to the above recommendations. Copy all codes and code Details. Yes. Stratified charge performance check, NOx sensor. Can anyone here help ? BMW does not say to us. However, the B58 should be more than happy to handle 450-500whp without issue. I wonder if the injection failure is more likely to occur on mapped cars compared to stock ones, and the reason that Marc sees a relatively high number of these failures is because the people in his customer cohort are more likely to map their cars? Part 1. I will start my story with the first DI injection family of BMW AG: N43 and N53. Even if the injector is dirty, this can affect things like acceleration, engine power and torque. It is an inline-6 double overhead cam (DOHC) engine. Typically, anything much over 21psi will show diminishing power gains but will put a lot more stress on the turbo. What is the difference between NOXEM NOx emulator and OEM NOx sensor? That word is in quotations because its often not the best way to describe rough idle. Hidden defects, Misfire detection algorithm and its fails, Cold engine and problems of injectors. Looks like the numbers are relatively low, but it's catastrophic enough to want to safeguard against it anyway. After 5 mins parked engine off it went away . Baum Tools. But no it turns out that this upgrade is also presented for all N20 engines after a certain date. N series. Part 2, Importance of the service procedures. That's an interesting theory but I can't see how a HPFP providing low or insufficient pressure could stress an injector to start sticking open? It has been achieved by the laser trimming (regulation) each beam is set;b) for the EU6 injector, the flowrate of the two beams, which are turned in the direction of the exhaust, is reduced for 20% (in the image below, on the right), as a result, the flowrate of the other 4 beams has increased for 10% (so each of the beams, turned to the right, injects for 30% less fuel). All direct injected engines will likely need this at some point. Even then, its not truly needed.
