WARNING: This page is about a different car, the 2002 BMW 745i and 2002 BMW 745Li. However, it is still accessible from the selected car via links, so may be relevant.
Individual pairs of firing circuit wires may be repaired using BMW air bag cable kits. Only one crimping connector can be installed into a single wire. Wires cannot be lengthened as a result of the repair. Damaged wire or connectors in door wiring harness must be repaired by replacing the entire door wiring harness.
