This is a genuine BMW diode relay, part number 61 36 1 391 397. The number stamped on the part is 61361391397; BMW's catalog files it under the short number 1391397. You will find it on our Electrical shelf, under Relay. It supersedes the older number 1244019, so a part carrying that number is the same part.
It fits the E36 sedan and coupe (318i, 320i, 325i and M3, 1992–1999), with the M40, M42, M50 or S50 engines — and the European-market versions.
BMW draws it on 6 diagrams, among them Various Relays (61_0066) and Relay (61_0550). It weighs about 32 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.
