02 View BMW DiagramSee this part on the official exploded view→This is a genuine BMW voltage regulator, part number 12 31 1 432 965. The number stamped on the part is 12311432965; BMW's catalog files it under the short number 1432965. You will find it on our Electrical shelf, under Alternator with motor and mounting. It supersedes the older numbers 1702929 and 2246073, so a part carrying any of them is the same part.
It fits the E36 sedan and compact (318i, 1992–1998), with the M43 engine — and the European-market versions. It also fits the E46 sedan, coupe and touring (320i, 323i and 328i, 1999–2005), with the M52 engine — and the European-market versions.
BMW draws it on 12 diagrams, among them Alternator, individual parts 100A (12_0581) and Alternator, individual parts 80A (12_0628). It weighs about 129 g (0.3 lb).
We have not had one on the shelf yet. Request it and we will tell you when one comes off a car.
