Genuine BMW part 13 51 1 256 543: Warm-up regulator (exchange unit). The number stamped on the part is 13511256543; BMW's catalog files it under the short number 1256543. BMW's catalog calls it “Exch-Warm-Up Regulator”. You will find it on our Air Intake shelf, under Injection pump, control part, mixture c.. It supersedes the older number 1256538, 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 2 diagrams, among them Regulator Warm-Up-Phase (13_0087) and Mechanical Fuel Injection (13_0683). It weighs about 460 g (1.0 lb).

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