Verify the vehicle’s model year, engine designation notes, and rear brake configuration before ordering. Some listed BMW applications include production-date and performance-package exclusions, so match the fitment notes carefully. Inspect the connector shape, terminal count, and sensor routing before installation to confirm the replacement matches the original part.
