Original BMW Ignition Switch for BMW E60 5 Series, E63 and E64 6 Series, M5, and M6 (2004–2010)

Made in Germany, Original BMW ignition switch 61-32-6-937-075 starts the engine and switches power to the accessories on 2004–2010 BMW 5 Series, 6 Series, M5, and M6 models from the E60, E61, E63, and E64 generation. The switch works with the key or start button, moving through off, accessory, on, and start positions that each power different vehicle functions. Ignition switches are a common replacement on older BMWs. A failing unit can leave the engine refusing to start or cranking only intermittently, and it can cut power to the radio, lights, or windows even with the ignition on. BMW began production of this switch in March 2003.

Original BMW Parts carry a 24-month parts warranty.

This number supersedes the earlier switch, 61-32-6-922-643, and BMW rates the change as exchangeable retrospectively, so it covers early cars built with the older part as well as later ones. One switch serves the whole range here, from the six-cylinder 525i, 528i, 530i, and 535i to the V8 545i, 550i, 645Ci, and 650i and the V10 M5 and M6, across sedan, Touring, coupe, and convertible bodies, pre-facelift and facelift alike.

The engine failing to start or cranking intermittently is the most common sign. Accessories shutting off unexpectedly in the on or accessory position is another.
