Genuine BMW part 12 31 8 510 088: Voltage regulator. The number stamped on the part is 12318510088; BMW's catalog files it under the short number 8510088. You will find it on our Electrical shelf, under Alternator with motor and mounting. It supersedes the older numbers 7567619 and 7568258, so a part carrying any of them 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 5 diagrams, among them Alternator 140/150A (12_1310) and Alternator (12_1419). It weighs about 150 g (0.3 lb).

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