02 View BMW DiagramSee this part on the official exploded view→Genuine BMW part 12 31 7 788 246: Voltage regulator. The number stamped on the part is 12317788246; BMW's catalog files it under the short number 7788246. You will find it on our Electrical shelf, under Alternator with motor and mounting. It supersedes the older number 2249968, so a part carrying that number is the same part.
It fits the E46 sedan, touring and compact (318d, 318td, 320d, 320td and 330d, 1998–2004), with the M47, M47N or M57 engines.
BMW draws it on the ALTERNATOR PARTS 120A/150A Valeo (12_0914) diagram. It weighs about 98 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.
