Any E30 OBC will work, there is a coding plug on the back. For your M3, the
code will be displayed if you press the 100 and the 1 button at the bottom of
the unit together. The display will read 3 - 1.1 TYP. Just remove your
coding plug and install into the new OBC. BTW, if you press the 1000 and the
1 buttons together, you will get the fuel remaining in liters.
