Genuine BMW Part

Photos coming soon

This is a genuine BMW voltage regulator, part number 12 23 7 791 139. The number stamped on the part is 12237791139; BMW's catalog files it under the short number 7791139. You will find it on our Electrical shelf, under Generator cooling. BMW has since replaced it with 7792387.

BMW's catalog records no E36 or E46 it is fitted to; it belongs to other BMW models.

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