Used OEM BMW ground cable strap part number 3420477, also replacing 3402862, 3420482, and 3405888. This genuine ground cable provides the electrical return path between the engine and chassis on the X3 with 2.5L or 3.0L naturally aspirated inline-six engines (M54 or similar). When the strap corrodes or breaks, symptoms include hard starting, dim lights, or intermittent electrical gremlins. A straightforward bolt-on replacement that restores proper grounding.
