Hi guys.. the question is:

Can I change the FRONT POSITIVE BOX without reprogram module?

My problem is: This box is not sending 12v to starter motor(only 3v)

Now I need to change to new one.

This box it’s where we use to update the battery

I'm not a BMW programming ninja but I'd say no that doesn't need any reprogramming since that isn't an electronic module. Appears to just be a power relay. Someone more knowledgeable may chime in though.
