Sorry guys if this is a noob question, but I got a check engine light in my 90 325is and i did the fault code check and i got 1211 = DME control unit. Now what is that unit and where is it located so i can replace it.
also can i replace it from an earlier bmw model say an 86 325es or 88 325is?
thanks
Luke
