Found the problem was #1 coil, replaced and runs great.

How do you erase a bad code, some cars you can disconnect the battery and that will do it but how on the BMW

I think, you have to use special tools to erase a bad code on your car.
anyway, dont disconnect the battery....it will give an effect to your bmw.
