Are these correct values for n63 engine?

RE: Are these correct values for n63 engine?
The different cylinders have each misfired a different number of times. The DME keeps a rolling tally of how many times each cylinder has misfired. It helps to determine if you have a problem with a plug/coil/injector.

That should give you an idea about how often you get a misfire on that cylinder. Then consider how many times in that distance your cylinder has had to fire. That should give you a pretty good idea of what % of fires are misfires. |

So it misfires in every 17kms. Is it good or not? Must be so or not? injectors are index 11

At an average rpm of 2000 that is 1 misfire every 25000 times it has fired. If it was every 100 times then you would have an issue but 1 every 25000 is hardly significant. |

Thank you very much but do not have an idea why it happens. Car was new, has only 42000km. What to replace in order not to have this misfire? Injectors are index 11.
