Genuine BMW part 12 32 1 739 435: Voltage regulator. The number stamped on the part is 12321739435; BMW's catalog files it under the short number 1739435. You will find it on our Electrical shelf, under Voltage regulator. It supersedes the older numbers 1437340, 1735788 and 2244626, so a part carrying any of them is the same part.

It fits every E36 body style (318i, 318ti, 320i, 323i, 325i and 328i, 1992–1999), with the M40, M42, M43, M44, M50 or M52 engines — and the European-market versions.

BMW draws it on 16 diagrams, among them Alternator, individual parts 80A (12_0468) and Alternator, individual parts 80A (12_0470). It weighs about 101 g (0.2 lb).

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