-Control unit (exchange unit) — a genuine BMW part, number 12 71 1 403 275. The number stamped on the part is 12711403275; BMW's catalog files it under the short number 1403275. BMW's catalog calls it “Exch.-Control Unit”. It supersedes the older number 1403274, so a part carrying that number is the same part.

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

BMW draws it on the EML control unit (12_1663) diagram. It weighs about 957 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.
