Ultrasonic transducer, painted — a genuine BMW part, number 66 21 2 180 144. The number stamped on the part is 66212180144; BMW's catalog files it under the short number 2180144. You will find it on our Instruments & Electronics shelf, under Other Cruise control, remote control parts. It supersedes the older number 0143458, so a part carrying that number is the same part.
It fits the E46 coupe, convertible and touring (323i, 325i, 328i, 330i and M3, 2000–2006), with the M52, M54, M56 or S54 engines — and the European-market versions.
BMW draws it on 3 diagrams, among them Ultrasonic-sensor (66_0228) and Ultrasonic-sensor (66_0273).
We have not had one on the shelf yet. Request it and we will tell you when one comes off a car.
