The cost of replacing a BMW high-voltage safety switch module varies according to the exact module, whether the part is new or used, workshop labour, required programming and the diagnosis needed before installation. An accurate price requires VIN-based compatibility checking and confirmation from the original module’s complete label. The marked number 8667593-02 may identify a shortened reference or revision, so it should not be treated as the definitive BMW ordering number.

Items that should appear in your replacement estimate

Your estimate should distinguish the module price from BMW-compatible scanning, safe high-voltage isolation, removal and installation labour, post-repair testing and any required coding or commissioning. Compatibility can differ between F30, F15 and G30 electrified vehicles, including the 330e, X5 xDrive40e and 530e, depending on production date, battery version, connectors and superseded part numbers. A drivetrain warning, charging failure or inability to enter READY mode does not prove that this module is defective; similar symptoms can result from the 12-volt battery, interlock wiring, contactors, charging electronics or battery-management system. Request the recorded fault codes and test results before authorising replacement. Work around the high-voltage battery and orange cables must be performed by a technician trained to isolate the system and verify that it is safe.
