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? Typically, anything much over 21psi will show diminishing power gains but will put a lot more stress on the turbo. Changed all spark plugs and coil pack changed oil too . Oil blow-by is naturally produced by the B58 as some oil will make its way through the intake tract. Interestingly mine has 13538625396 fitted, did yours have 13-53-7-639-990? But did not have any other issues. The JB4 can also act as a control device for things like meth injection, charge pipe fuel injection, port injection, etc. Will report back with results That should do it. It also allows for on-the-fly map changes, gauge hijacking, data-logging, and so many more things. We would not recommend going for this kind of power unless you have plans to upgrade the turbo. 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. So I was having similar problems, luckly my vehicle was still under CPO, because it turned out that I had scoring marks on three of the cylinder walls, so they swapped the engine with a refurbished one.. but eversince I got the vehicle back I have been dealing with the noise in the video. have you guys experienced this ?

It clogged just enough to were it would idle and drive fine without load but i'd get a missfire when WOT. The B58 is part of BMW's new modular engine family, each engine using a displacement of 500 cc (30.5 cu in) per cylinder, following the B38 and B48 engine.. Lieutenant . Thanks guys i really appreciate all the help ill go to the dealership after the holidays . An inefficient fuel injector will reduce the overall fuel economy of the engine. Its a quality oil for a good price. The first one noted occurred in 2016 and it was not flashed.. JB4 only + meth and luckily the dealer covered it. What would I do, if I had the engine, equipped with these injectors?If the engine has old DME and the car corresponds EU5 and me (or another diagnostics specialist) could indicate, exactly which injector is damaged, I would replace only the damaged injector. There was no need for two injection impulses anymore. Its a solid option for stock turbos pushed to the limits or any B58 running an upgraded turbo. 220.00. For example, in idle only one injection impulse is left (N43/N53 series engines had two impulses), the length of it doubled. Originally Posted by G_B58.

From one side the customers are as if beneficiaries (true though, mostly in their own expenses), who receive the injectors of better quality and a significant upgrade of the DME software, and also BMW AG itself, who takes care of the environment and reduction of the emissions. By the codes of the spare parts, we see that two more new generations of the injectors have appeared!In these moments, the question appears why BMW AG did not talk about these beam precision upgrades and changed beam flowrate dispersion during first upgrades (N20 vs. N26)? Look for things like cooling system problems and gasket oil leaks. Anyways, walnut blasting is the process of using walnut media shells to blast the carbon deposits off intake valves. In my opinion, cylinder scoring is bad air intake or an oil problem. No scoring problems on my tracked car. document.getElementById( "ak_js_1" ).setAttribute( "value", ( new Date() ).getTime() ); Our site is dedicated to all things BMW Tuning related. **Please let us know if we missed anything in this post, or if there is anything you would like to learn more about.

Throttle and accelerator pedal. 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. Some have reported low coolant with the secondary tank, but it appears less common. In these engines, the same injectors as for N55/N20/N26 are used. 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? As with the N55, the B58 engine uses a single twin-scroll turbocharger. Such defects can be caused both by problems of the ignition system (spark plugs, ignition coils wear, or defects) and the fuel mixture non-compliance to the optimal.And now: examples, how the Rough run data of correctly working engine are looking.Idle: Low required torque (20 .. 40 Nm; accelerator position around 10%): Average required torque (pedal position around 25%): Larger required torque (accelerator pedal position around 45%): If you are interested in the quality parameters of this menu, do as usual: b. turn off the ignition coil of some cylinder for a running engine. Problems of air-tightness, Idle. Again, we absolutely love the JB4. How did DI fail on cyl 6 ? But there was a major update done in 2018 and then another for 2020. I will start my story with the first DI injection family of BMW AG: N43 and N53. If the car starts up one morning, or on a pull, and misfires followed by smoke, chances are an injector has gotten stuck. However, the JB4 can be stacked with a flash tune, known as a back-end flash. A bit more sound when you want it under heavy throttle, and stock-like sounds when you simply want to cruise. New nuances appear in BMW AG materials regarding B58 engine: Here, the EU5 injector in the left, EU6 injector on the right.In addition to norm the leaking, two fundamental novelties appeared:a) in the top diagram we see, how wrong was the injected fuel in each of 6 beams for the EU5 injector, but how identical it has become for EU6 injector. Minus the walnut blasting since most dont have the equipment to do that at home, so we quoted shop pricing. Why I put an accent to is available? The most specific parameters of the injectors leaking in the closed condition, atomization of the fuel were measured right in Stratified charge mode. 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? Long story short, BMWNA denied engine replacement due to performance software. BMW part number: 13538625396. 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.

What sort of personal outcomes are you looking for? 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. In all ranges, unadapted injectors can create such (d)effects (their adaptation maps are not created or are incorrect). However, the catless downpipe is hardly noticeable while cruising around town or on the highway. 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.

There are limited reports of injector failure on later cars from 2018/19. Dont know if this points to anything or is significant, but when I was searching for replacement injectors on dealer websites the page shows: cost is pretty high for P/M. Poor fuel economy. Typically, FBO on the B58 refers to a tune, intake, and downpipe. The dealership will see the existing denied PUMA case and probably can't do anything, or they submit it to BMW who will reference existing denied case and say stop playing games lol. Time will tell how often its necessary on the B58. Certain G series models began receiving the updated B58TU1 in 2019. As with many turbo BMW engines the B58 loves to burn through spark plugs. Good question, and there is no perfect answer. Drives: 2011 E92 BW. They also recommend using an LL-14 FE+ approved fuel. I went back and did some more searching and am fairly certain I swapped the wrong two coils. Individual adaptations of injectors.

Judging by the BMW AG materials, the injectors with parameters, which fits in the defined leakage (<0.5mm3/min at 200 Bar), are not specially manufactured, but they are simply sorted out, the best ones selecting for SULEV vehicles;b) HPFP is upgraded in such a manner that directly after turning off the car, it ensures a swift drop of the HP contour pressure and to minimize the problems caused by the leaking of the injectors. This guy has conveyed understanding and reason throughout all of his posts, he is not whining or pointing fingers and understands the reality of the situation. Theres no right answer, but in general the B58 should last as long as youre willing to continue repairs and standard maintenance. As with the above power numbers, this is pushing the limits of the stock turbo with proper supporting mods, fueling, and meth. 2days later at the traffic light medium throttle it happened again . But. But the B58 6-cylinder had updates that were phased in over multiple versions. Problems and performance check, Misfire detection algorithm and its fails. Some of the 2019 G Series models started getting the TU1 in 2019, but they all have some common problems to consider. Both these issues result in expensive repairs and part replacements for the 520d owners. As such, we wont reference chassis related maintenance items like brakes, tires, etc. Part 2. Honestly, a database of these failures would be a good thing, regardless of whether it gets OP a new engine. Also curious what made you go PI meth over PI e85? Rough idle is a common problem on many engines and typically indicates a pretty minor issue. Speeds upwards of 180-190mph are possible with tunes and bolt-ons.

Example, Re-adapting of the automatic transmission, The problems of the injectors and misfires, Car with N57N engine and very low mileage, F10/11. Now that motor is torn down, what damage was done to #6 ? Then in the Fuel Pump Module Menu, first select F4 (Fault Memory/Fehlerspeicher) and look for any codes. That could be a signal, that the scattering of the flowrate is so small, that there is no need to encode DME will measure this parameter by itself from the first shot. I'm not sure if these changes in the B58TU have anything to do with this. However, time will tell just how bad the valves look around the 100,000+ mile mark. Stratified charge performance check. Its tough to say. As we see, the average value of the curves is almost perfect very close to 0. Well discuss this more in the next question below. What exactly do you expect to achieve here? No possible repair only complete 40k engine replacement . 5. 71. 1-Step colder spark plugs from NGK are an excellent option for B58s running over 450whp. Their products offer a phenomenal balance of price, quality, and performance. Obviously, these upgrades were not yet introduced at that time! This means each cylinder uses 2 exhaust and 2 intake valves for a total of 24 valves. While both carry an M-badge only one of them is truly an M the BMW M3. Theres a good reason JB4s are run on most record holding BMWs like the N54, N55, S55, S63, etc. F10/11. Such a solution has as if improved the fulfillment of cylinders. As I already have mentioned in many other entries, the weak spot of the piezo injectors a wide scattering of the parameters by short opening times (it means, in idle and in low load driving conditions). Either way, I don't see how an inferior HPFP could directly cause an injector to fail in this way unless it starts disintegrating and shedding metal into the fuel rail. Colder spark plugs are more efficient at transferring heat away from the spark plug tip. The TU1 update is mostly intended to improve emissions. The recommended oil weight from BMW is 0W-20. Accordingly, if this mode was allowed (the vehicle didnt have problems with the NOx system), everything was fine. As we discussed briefly above, the N55 was an improvement over the N54. Stratified charge performance check, NOx sensor. We recommend a 50/50 mix of water and coolant for the B58. Coolant also helps prevent corrosion. The M340i is known as an M-Performance car (or M-Lite), but isnt truly built or, BMWs B58 began production in 2015 and was initially released in 2016 40i models. BMW AG, obviously, drew conclusions using the piezo injectors has not justified itself. Unusual odor. F10/11. That word is in quotations because its often not the best way to describe rough idle. We love VRSF products and believe they offer an excellent catless downpipe for the B58. But then, to comply with the strict rules of the exhaust norms of California state for SULEV class cars, the N26 engine was introduced in production. Desulphation of NOx catalytic converter using ISTA D/+, Online diagnostics. The labor work costs 50$ to 150$, depending on the workshop. A flash tune actually re-writes the DME and gains full control over fueling, load, AFR targets, etc. What is the difference between NOXEM NOx emulator and OEM NOx sensor? Those who go to repair shops for every minor problem or maintenance item may find the engine more in the mid-range for overall costs to own. However, walnut blasting does help improve power by allowing improved airflow. Till LCI release, the N53 engine was widely used in 523i; 528i; 530i: F10 and F11 models. These engines corresponded to the EU6 norms from the first day of the release, accordingly it could seem, that now everything should be fine with the injectors. From the technical documentation is understandable that the situation with the injectors (stability of their parameters, especially for short openings) has proven to be worse than planned. Rough run. Smooth run. Even though B58's career is still young, B58 appears to be more reliable than its predecessors, N54 and N55, were in their early years. The B58 crankshaft is made of forged steel. Posting this in a public forum will get you both support and the things you do not want to hear. ~480-500whp. Please ensure your correct model is selected. Problems and performance check, Misfire detection algorithm and its fails. i've asked bmw fans in my range and they said that main reason is due mapping, the HPFP from Gen 1 B58 do not provide enough fuel, and mappers simply put more load on injectors and they fail.
