04 View BMW DiagramSee this part on the official exploded view→This is a genuine BMW voltage regulator, part number 12 31 1 748 607. The number stamped on the part is 12311748607; BMW's catalog files it under the short number 1748607. You will find it on our Electrical shelf, under Alternator with motor and mounting. It supersedes the older number 1730601, so a part carrying that number is the same part.
It fits the E36 sedan, coupe and convertible (320i and 325i, 1992–1995), with the M50 engine.
BMW draws it on 9 diagrams, among them Alternator Parts 90a (12_0497) and Alternator, individual parts 105A (12_0498). It weighs about 101 g (0.2 lb).
We have not had one on the shelf yet. Request it and we will tell you when one comes off a car.
