There is no perfect answer to this. A PUMA case was most likely opened for engine failure (these are rare). Anyways, we ultimately recommend the JB4 and well dive into that more. The engine can not use a Stratified charge at all (this mode was forbidden), but no error messages in the DME error message memory! What exactly do you expect to achieve here? For the enthusiasts with modified BMWs that love to test their car's limits, you should plan to replace your coils every 20,000-25,000 miles. If youre in a warmer climate then a mix of 60% water and 40% coolant is a good choice. Spark plugs are a standard maintenance wear and tear item. 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. We truly believe a JB4 + BEF is the ultimate tuning solution. Issues such as HPFP and fuel-injector failures were no problems yet for B58s but let us assess some common ones: Coolant Loss Part 2. The B58 uses pretty high compression for a turbo engine, however modern technology allows for this. Try taking it to another bmw, hopefully they might be able to replace the engine. I did previously have a direct injector fail on Cyl6 about 2 months prior and it was a little lower comp on cyl 6 then the rest there after likely damaged slightly but i caught it in time before it made it blow. Look for things like cooling system problems and gasket oil leaks. The B58 has 24 valves. Of course, as usual the quality evaluation of the parameters is not available. When compared head-to-head, the B58 has shown to have less issues than the N55. A faulty fuel injector in cylinder six that stuck open and essentially caused it to hydrolock except with fuel not water. New. 340i and 440i models received the 320hp variant with 332 lb/ft of torque. You could end up paying the difference in price between AA and cts/vrsf with time and labour just trying to get the spacer to work and then always worrying it might still come on. Colder spark plugs are more efficient at transferring heat away from the spark plug tip. Simple Yet Solid. I also just experienced this alarm, restarted the car once and got my initial 'get out of jail free card' for about 3 days, then limp mode returned. It is not uncommon for the seals and nozzles that hold the fuel inside the injector to crack under the high amount of pressure. Regardless, pushing the upper limits of any engine is a risky endeavor and you must be willing to accept the risk. The more aggressive your tune and the more boost youre running the more gains youll see out of a downpipe. 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. Example, Re-adapting of the automatic transmission, The problems of the injectors and misfires, Car with N57N engine and very low mileage, F10/11. Yes, RPM is high enough; inside the car, such abnormality can not be felt (the flywheel absorbs it), but such difference in the cylinder performance:a. gives increased load on the CO catalytic converters and damages them;b. reduces max torque of the engine;c. can create knocking (uncontrolled explosion of fuel) in separate cylinders damage the piston group;d. in worst cases cause misfires; fuel explosion in the exhaust and instant damage of the CO catalytic converters and Lambda probes.Causes of the defect:a. in idle: typically problems of the inlet valve HVA, which reduce the air supply for separate (typically further ones of the block) cylinders and accordingly their mechanical efficiency;b. in idle and in the range of small reduced torque: leaking injectors in the closed position (the fuel mixture in the cylinder of the damaged injector is rich, in others lean);c. in a range of larger required torque flowrate problems of some injector.Notes. Search Entire Site . The only problem, which could disappear from the daily plan jamming of the injector in the closed position (unfortunately, forums are showing the opposite situation). An example. The N54 takes the cake in regards to horsepower capabilities, but it had many engine problems as a result.

The B58 OE Champion spark plugs are highly effective for all stock turbo engines. Copy all codes and code Details. 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. Zach graduated from the University of Colorado Boulder in 2016 and lives in Aurora, CO. New. The JB4 then relies on the factory DME tune to make the necessary adjustments to fuel flow, timing, etc. . Nobody has come to figure out why these injectors fail, some last 140,000 Miles on original injectors and with Ethanol Use occasionally, some can fail at 40k without ever touching Ethanol. Look no further. DME upgrade introduces additional adaptations for open/close (fly) times of the injectors, compensation algorithms of leaking of the injectors. Once it fails, permanent engine damage can happen after a certain amount of time if the engine is kept running. From what I've read this issue was only on 2016 plates and some 17 plates. 2007 Jectron Gasoline Fuel Injection Cleaner, 300 ml. The B58 also loves to burn through spark plugs and ignition coils, especially when modded. 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.
