Genuine BMW part 82 11 9 418 405: Ultra sonic-module. The number stamped on the part is 82119418405; BMW's catalog files it under the short number 9418405. You will find it on our Merchandise & Accessories shelf, under Other Universal Accessories parts. BMW has since replaced it with 9401798.
It fits the E36 sedan, coupe and compact (318i, 318ti, 320i, 323i, 325i, 328i and M3, 1992–1999), with the M40, M42, M43, M44, M50 or M52 and other engines — and the European-market versions.
