Bmw i3 drivetrain error P0301 P0302 P0300

[Rapgain]

One day my i3 suddenly turned off with drivetrain error. After linking obd scanner it showed misfiring on both cylinders. I've checked everything submitted by reinhold in this case, even rdme with its sensor of the level above the sea. I've swapped the coils, plugs, and fuel injectors, fuel relay. I've got out the engine, checked the system of gas distribution. Everything is up to admission. Can anybody share your experience, if you faced same issue. Thanks in advance
