Genuine BMW part 12 31 7 546 284: Alternator. You will find it under Electrical (Alternator with motor and mounting). It supersedes the older numbers 12 31 7 519 721 and 12 31 7 519 723, so a part carrying any of them is the same part. BMW has since replaced it with 12 31 7 541 694.

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

BMW draws it on the Generator, individual parts drawing. It weighs about 6.8 kg (15 lb).

Out of stock. Request it and we will notify you when it is in stock.
