Compact generator (exchange unit) — a genuine BMW part, number 12 31 7 509 110. You will find it under Electrical (Alternator with motor and mounting). It supersedes the older numbers 12 31 7 509 113 and 12 31 7 511 604, so a part carrying any of them is the same part.

BMW draws it on 3 drawings, among them two Compact Alternator drawings. It weighs about 5.8 kg (13 lb).
