14 View BMW DiagramSee this part on the official exploded view→Genuine BMW part 12 31 1 735 742: Voltage regulator. The number stamped on the part is 12311735742; BMW's catalog files it under the short number 1735742. You will find it on our Electrical shelf, under Alternator with motor and mounting. It supersedes the older number 1731908, so a part carrying that number is the same part.
BMW's catalog records no E36 or E46 it is fitted to; it belongs to other BMW models.
BMW draws it on 12 diagrams, among them Alternator Parts 140a (12_0251) and Alternator Parts 140a (12_0253). It weighs about 58 g (0.1 lb).
We have not had one on the shelf yet. Request it and we will tell you when one comes off a car.
