-Control unit (exchange unit) — a genuine BMW part, number 12 14 1 284 409. The number stamped on the part is 12141284409; BMW's catalog files it under the short number 1284409. BMW's catalog calls it “Exch.-Control Unit”. You will find it on our Electrical shelf, under Other Engine Electrical System parts. BMW has since replaced it with 0028580.

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

BMW draws it on 2 diagrams, among them Control unit (13_0194) and Control unit (13_0206). It weighs about 962 g (2.1 lb).

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