Crash alarm relay — a genuine BMW part, number 61 35 1 384 732. The number stamped on the part is 61351384732; BMW's catalog files it under the short number 1384732. You will find it on our Electrical shelf, under Control units, modules. BMW has since replaced it with 8364691.
It fits the E36 sedan, coupe and convertible (318i, 320i, 325i, 328i and M3, 1992–1999), with the M40, M42, M43, M50, M52 or S50 engines — and the European-market versions.
BMW draws it on 5 diagrams, among them Various Relays (61_0066) and Various Relays (61_0571). It weighs about 35 g (under 0.1 lb).
We have not had one on the shelf yet. Request it and we will tell you when one comes off a car.
