This is a genuine BMW additional alternator, part number 12 31 1 466 340. The number stamped on the part is 12311466340; BMW's catalog files it under the short number 1466340. You will find it on our Electrical shelf, under Alternator with motor and mounting. BMW has since replaced it with 1731103.

BMW's catalog records no E36 or E46 it is fitted to; it belongs to other BMW models.

BMW draws it on 2 diagrams, among them Additional Alternator/Mounting Parts (12_0385) and Additional Alternator/Mounting Parts (12_1597).

We have not had one on the shelf yet. Request it and we will tell you when one comes off a car.
