Generator, water-cooled (exchange unit) — a genuine BMW part, number 12 31 7 508 286. The number stamped on the part is 12317508286; BMW's catalog files it under the short number 7508286. BMW's catalog calls it “EXCH generator, water-cooled”. You will find it on our Electrical shelf, under Alternator with motor and mounting. It supersedes the older number 7508258, 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 the Generator, water-cooled (12_0981) diagram. It weighs about 9.4 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.
