I'm gonna email my dealership. I wonder if the service computer has to be reset after the fluid change too.

There is a special procedure

However, it is rarely done

I've confirmed this with both independent and BMW technicians

In theory, if you want to replace all of the old fluid it should be done

Whether or not it is really necessary is a matter of debate

You will also want to consider changing and bleeding the clutch fluid as it shares the same reservoir as the brakes
