Genuine BMW part 12 31 7 509 109: Generator, water-cooled (exchange unit). The number stamped on the part is 12317509109; BMW's catalog files it under the short number 7509109. BMW's catalog calls it “EXCH generator, water-cooled”. You will find it on our Electrical shelf, under Alternator with motor and mounting. BMW has since replaced it with 7526285.

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

It weighs about 9.3 kg (21 lb).

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