Genuine BMW part 12 31 7 532 964: Alternator. You will find it under Electrical (Alternator with motor and mounting). It supersedes the older numbers 12 31 7 521 489 and 12 31 7 533 272, so a part carrying any of them is the same part. BMW has since replaced it with 12 31 7 533 268.

Fits E46 316i, 316ti, 318i and 318ti (2004) with the N45 or N46 engines.
