Cable alternator-starter — a genuine BMW part, number 12 42 1 439 743. The number stamped on the part is 12421439743; BMW's catalog files it under the short number 1439743. You will find it on our Electrical shelf, under Other Engine Electrical System parts.

It fits every E46 body style (320i, 325i and 330i, 2001–2006), with the M54 or M56 engines — and the European-market versions.

BMW draws it on 3 diagrams, among them Compact Alternator (12_0626) and Cable starter (12_1106). It weighs about 190 g (0.4 lb).

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