Genuine BMW part 61 31 1 378 211: Relay battery disconnection. The number stamped on the part is 61311378211; BMW's catalog files it under the short number 1378211. You will find it on our Electrical shelf, under Switch. It supersedes the older number 1366203, so a part carrying that number is the same part.

It fits the E36 sedan, coupe and touring (318i, 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.

BMW draws it on 12 diagrams, among them Installing Set 2.Battery (03_3490) and Installing Set 2.Battery (03_3491). It weighs about 238 g (0.5 lb).

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