Alternator — a genuine BMW part, number 12 31 1 734 322. The number stamped on the part is 12311734322; BMW's catalog files it under the short number 1734322. You will find it on our Electrical shelf, under Alternator with motor and mounting.

It fits the E36 sedan and coupe (318i, 1992–1999), with the M40 or M42 engines — and the European-market versions.
