This is a genuine BMW basic control unit DME (exchange unit), part number 12 14 1 404 270. The number stamped on the part is 12141404270; BMW's catalog files it under the short number 1404270. BMW's catalog calls it “EXCH Basic control unit DME”. You will find it on our Electrical shelf, under Other Engine Electrical System parts. It supersedes the older number 1403611, so a part carrying that number is the same part. BMW has since replaced it with 1404738.

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

BMW draws it on the Uncoded DME control unit (12_1672) diagram. It weighs about 575 g (1.3 lb).

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